yea, i have been remixing music on my computer for close to a year now, and i have gotten real good... well at least up to my expectations. I have been looking for a turntable.. really the only thing i want a turntable for is so i can scratch to my remixes.
My neighbor has one and will probably sell it to me for very cheap, like 25 bucks. and i am just wondering, if all i need is a turntable to do what i want to do, because ill probably need a mixer and an amplifier, i dont know, im so clueless about turntables its not even funny, i just really want to get involved with them and whoever this email goes to, please help me out, give me a list of the things i need to hook up a turntable and make it work and everything... please...

Turntable: There should be a rubber cover on the platter, take it off to expose holes that allow you to see the belt. Get a grip on the platter and turn in clockwise while pulling it upwards. It should come out then.

DMV: Get a piece of notebook paper and roll it into a cone (.3" diameter on small end / 2" diameter on large end). Connect the safety pin to the small end and touch the point to a spinning record. You are now Edison, MUSIC IS MAGIC.

I've got a Sony turntable that's just used for domestic purposes (no DJing) that's got a power cable connected to the back. The end of the cable is just this tiny bi-pinned thing that plugs into the back of the main console. Only thing is, the main console doesn't work anymore and I can't find that particular slot on any other console, including other Sonys.

Any clue on what I can do?

Do you live in a major city? If so go to a pawn shop and buy a Technics 1200. The pawn shops are stocked with them at the moment because urban ding-dongs learned DJing is harder than in looks. Pay no more than $175 and you have a turntable FOR LIFE.

PP - see if anywhere on the turntable or the console it says what the voltage is of the output of that 2-prong plug. If it's standard household current, you can just cut the cord and put on a regular outlet plug. If it's DC, you can probably find a power supply to match.

If you can't figure it out, post the model numbers

dave vire think (dave225.3), Monday, 17 April 2006 00:02 (sixteen years ago) link

It's a DC 12 volt. Not exactly household, is it?

Pleasant Plains /// (Pleasant Plains ///), Monday, 17 April 2006 00:51 (sixteen years ago) link

No, but 12VDC should be easy to find a power source, if you're comfortable with twisting some wires together. You can use an old PC power supply (or a new one) or buy an 12V transformer. You might even be able to pull the transformer out of the console if the transformer part still works...

I'm now using a Yamaha P-750 for the home. It sounds just great. However, it is loaded with buttons and knobs, and its manual has never been posted online. Anyway, there is a LOCK/FREE flipswitch by the base of the tonearm. I've farted around with the thing, but I don't know what it does. Help!

QuantumNoise, Sunday, 7 October 2007 19:31 (fourteen years ago) link

I'd imagine it is to lock it in place when you transport it so the tonearm doesn't get damaged.

Chewshabadoo, Monday, 8 October 2007 13:11 (fourteen years ago) link

Thanks. I'll try securing the tonearm in the clasp, then flipping the switch to LOCK -- see if that somehow locks it in there.

I have just purchased a Pro-Ject Debut III (partly due to people recommending it here) and am finding there's something weird about the tonearm/cartridge/needle/I'm not sure — I get this humming sound, mostly in the right channel. If I move the tonearm a little, especially if I lift it so it touches the anti-skating weight support hoop, I can usually get the hum to go away... but it comes back after a few minutes.

Does this sound familiar? Is there a way to fix it? Do I have to "adjust the azimut," whatever that is?

This is my first serious turntable — before I just had this old Garrard changer and didn't ever have to do any assembly or anything, just replaced the needle once or twice.


eatandoph, Saturday, 1 March 2008 07:25 (fourteen years ago) link

Do you have the grounding wire connected? (little fork shape cable that runs beside the two phono connections - should screw on to a post on your amp/ phono stage)
If that's not it then it might be a loose connection from the arm to the cartridge - 4 connectors with fiddly little sleeves that fit over 4 posts on the cartridge; try touching them one by one and see if the hum changes or goes away...

sonofstan, Saturday, 1 March 2008 08:11 (fourteen years ago) link

Thanks for your reply. The grounding wire is connected. If I touch the metal screws connecting the tonearm to the cartridge, the hum reduces but doesn't quite disappear. Touching the sleeves (black, rubbery things?) makes the hum louder.

eatandoph, Saturday, 1 March 2008 08:26 (fourteen years ago) link

Ok - without hearing the hum, its hard to tell (and might be hard to tell anyway) if it doesn't entirely disappear when you touch anything on the cartridge, it suggests a more fundamental earthing problem; if you've just bought this, the safest - and cheapest - thing might be to bring it back to the shop, and either get a replacement or get them to fix it......

sonofstan, Saturday, 1 March 2008 13:12 (fourteen years ago) link

I just had a similar problem and it ended up being an internal ground in the cartridge itself. Replacing the cartridge solved it....if it's a good shop they should definitely be willing to replace or fix.

I have a Rega so I'm not sure exactly how the Pro-Ject's ground out...the Rega ground internally in the arm...so it could be a number of things but maybe if you have another old cartridge around it might be worth throwing it on just to see if that solves it.

M@tt He1ges0n, Saturday, 1 March 2008 14:43 (fourteen years ago) link

Thanks again.... I ordered the turntable from NeedleDoctor, which makes returning it a hassle, but I'll probably do that since even the prospect of replacing the cartridge frightens me terribly. (NeedleDoctor provide a link to this Beginner's Guide, but just the list of "tools at a glance" is intimidating.)

eatandoph, Saturday, 1 March 2008 20:19 (fourteen years ago) link

Just read the guide....... have the say, I've changed cartridges without a tweezers loads of times but it makes sense to use one; is there anyone local who does repairs who could swap the cartridge if just to eliminate that?

Hey guys I've got a Pioneer PL-990. My cat knocked it off the stack last night and I think the motor might be fucked up: the platter is spinning v irregularly. I thought I might just need to rethread the belt, so I did, but no dice.

Any other suggestions? If it is the motor, is it cheaper to get a motor and repair/have it repaired, or do I just need a new turntable?

A repair might work, but it's going to cost you parts and labor and you'll still be left with a Pioneer deck. Double your costs and you could end up with something much better—for example,

hoos, kinda echoing michael, but yeah getting them fixed is tough. very few places fix turntables anymore, don't know abt your city.

if you don't want to step up to the 300+ range, like the Rega P1 (which i own) or the Pro-Ject, then i'd definitely check craigslist you can find some great deals on there.

remedial turntable question: with an old, 80s all-in-one cassette/turntable unit, will a microphone input work as a line-in/auxiliary setting? would i be able to run music from a computer through the stereo? and is there a big disadvantage in it being a single jack input, rather than a dual phono red/white input?

schlump, Tuesday, 30 September 2008 14:50 (fourteen years ago) link

I would try it, but most mic imputs are a lower impedance level than line inputs. some of those older systems have built-in preamps though. the jack is probably 1/4" stereo, but it might be mono (which might also be a problem for you).

sleeve, Tuesday, 30 September 2008 14:56 (fourteen years ago) link

ehh, i think i might just go for it. there's always headphones if not. thank you.

schlump, Tuesday, 30 September 2008 14:59 (fourteen years ago) link

i bought this, by the way, it being small enough to fit my needs and also being really cool. i was shocked - SHOCKED - to see how cheap stereos are generally on ebay, though; anything without a cd player, even if it's separates with a turntable and decent speakers, can be had for >$75, inc. shipping.

cozwn, Thursday, 15 January 2009 00:59 (thirteen years ago) link

I have an experience receiving turntables sent air mail.

Dust covers shattered, a lag (in the spinning part) in both of them which never really went away, and unsurprisingly little foam/air bags in the box.

Should have known, the guy's name was Elvis Santana.

mehlt, Thursday, 15 January 2009 01:05 (thirteen years ago) link


did you get a refund?

cozwn, Thursday, 15 January 2009 01:06 (thirteen years ago) link

At a minimum you need to strip the thing down. Most important is to take the platter off. I'd pack it under the turntable where it can do the least harm

There are also sometimes shipping screws for the suspension accessed from under the turntable. If you don't have a manual for the 160, sometimes you can get one online. Tightening the screws will immobilize and protect the suspension.

Tie down, or tape down the tonearm to the support so that it can't get loose and damage itself or the stylus.

If the stylus has a cover, pop it into place, or take the stylus out if that's easily done. Some styli come as an insert that is removable from the larger cartridge.

Unscrew the counterweight from the tonearm.

In a perfect world, think about shipping the plexiglass cover separately. They're fragile and crack/scratch easily; if you don't pack well, the turntable (and especially the platter) can shift around and damage them.

Michael Train, Thursday, 15 January 2009 03:47 (thirteen years ago) link

Xpost, we sent back the non-working mixer and got much more than it was worth. I managed to get two years of use out of those turntables though, although there were always good and bad days with them.

If you have an original box they came in, preferably with appropriate fitting pieces of styrofoam that keep it in place, I imagine that would be a good receptacle.

reposted from another thread (threads, actually, my mistake(s))

I think I'm going to get a new set of Shure cartridges
I'm looking at these and realizing that it might be worth the extra 17 (X 2) dollars to step up to something better, namely the M44-7, especially if it's going to have a significantly longer life than a more entry level cartridge.

I really don't know anything about needles, I'm changing them now because I got a pair that came with used turntables and I'm afraid they're worn out (there's skipping here and there, sometimes I have to raise the counterweight, etc.), but ultimately I have no idea. I'm not playing at clubs or on a HiFi system, so I'm not sure (not shure?) what difference it ultimately makes for someone like myself.

EDB, Wednesday, 16 September 2009 14:57 (thirteen years ago) link

It's going to wise to change your cartridges if they've seen a lot of use as they wear down, and eventually get to a point where they might start damaging your records.

Always set the weight of the cartridge to the maximum recommended by the manufacturer - less weight could mean the arm may bounce up and down, again damaging records. As a general rule, hi-fi carts are set to around 1.5g, house and techno DJ carts where some back-cueing is used are around 3.5, and scratch DJs will use at least 5g to lessen the possibility of skipping.

Records skipping can sometimes just mean the records are damaged of course.

It's always good to have some spare cartridges around just in case anyway - they'll last virtaully a lifetime if not used.

Chewshabadoo, Wednesday, 16 September 2009 15:10 (thirteen years ago) link

I'm sure you know this, but for anyone who doesn't:


Chewshabadoo, Wednesday, 16 September 2009 15:13 (thirteen years ago) link

Actually ignore that - it's good up until point 4, which seems plain wrong. Just turn the counterweight to the required number which should correspond to the weight you are after. If setting DJ tracking weights you may need to add a weight to the headshell (very often this will be a small coin held on with blutack!)

Chewshabadoo, Wednesday, 16 September 2009 15:16 (thirteen years ago) link

The link that should have been where I wrote that was lost, so there it is again.

Thanks, though. Mainly I'm mixing records, so I'm concerned about wear. At this point I'm definitely going to buy new cartridges, the question is whether the M44-7 is worth the extra $17 (times two, $34) dollars over the M92E for a bedroom DJ like myself, looking in the long run (i.e. how long these will last for, etc.)

EDB, Wednesday, 16 September 2009 15:22 (thirteen years ago) link

Sorry, can’t help you there, I’ve always been an Ortofon man myself. The main thing to take into consideration with wear is that a spherical diamond will damage records much less when back-cueing, but will not have the clarity of an eliptical diamond.

Chewshabadoo, Thursday, 17 September 2009 12:34 (thirteen years ago) link

Well I got cartridges and everything is set up (properly, I hope). My question now is what's the deal with this screw in the cartridge at a 23% angle business? I've had Stanton cartridges which came pre-angled, but turned clockwise, and with a straight tone arm if that makes a difference?), but otherwise I am again in the dark, but it seems to make sense, and better tracking is better tracking...

Are there potential pitfalls to this? If it's angled at say 15, 20 percent will it make a difference?


EDB, Saturday, 19 September 2009 04:33 (thirteen years ago) link

You can get pfs of protractors to help with alignment. Make sure you print at 100%


I've just used the 'stupid protractor' in the past. Haven't bothered the last few times tbh.

Chewshabadoo, Saturday, 19 September 2009 09:08 (thirteen years ago) link

An hour researching on google and I still have no idea how to use that.

EDB, Saturday, 19 September 2009 16:07 (thirteen years ago) link

You just print them out, make a hole where the blank dot is and then place it on your turntable to see if the cartridge lines up (more or less) in both positions when viewed from above. Simples.

I'm thinking about upgrading before the end of the year and I'm batting about the U-Turn Orbit and the Pro-Ject T1. As much as I love fully auto or even semi auto turntables, I don't think going full manual would be too much of a drag, and I like the low profile appearance both of these tables offer. Anybody here have a preference between them? I rarely ever play anything on 45, so moving the belt between gears isn't really an issue.

Is a fully manual tt more annoying in reality than it is in my imagination?

Johnny Fever, Friday, 11 September 2020 23:41 (two years ago) link

once you are at peace with knowing you will eventually wander off/fall asleep and leave the needle riding the runout groove for 6-10 hours, it's fine

avellano medio inglés (f. hazel), Friday, 11 September 2020 23:48 (two years ago) link

Depends where the motor is. If it's in the chassis and you actually have to lift the platter off the spindle every time you want to change speed - that can get annoying. If it's outside the platter and it's just a case of nudging the belt up or down - no problem at all. Looks like the Pro-Ject T1 is the former, and the U-Turn Orbit is the latter. But I do like Pro-Ject stuff. I've had a Debut Carbon for the last five years and no complaints. I don't think U-Turn is available over here.

xp - oh yeah, the lack of auto-return; well, I haven't had that since my Ariston in the early '90s. If you want to listen to an LP, stay awake, stay in the room :)

Michael Jones, Friday, 11 September 2020 23:56 (two years ago) link

What's the real benefit to an acrylic platter, btw? I've already got an acrylic slipmat, so a platter might be overkill (though the T1 has a glass platter, so I don't know what I'd do in that situation).

I've been using an MCS 6502, which is really a rebranded Technics SL-23, and it's been good to me, but it's starting to have speed issues and I've fiddled with every remedy I can find short of replacing the motor. Also it's limited to the AT71 cartridge and nothing else because the headshell/cart combo isn't removable, so I'd like to have more options in that department as well.

Johnny Fever, Saturday, 12 September 2020 00:05 (two years ago) link

I think it's just heavier, denser, less speed fluctuations and less resonant. Whether you can hear any difference vs MDF is another matter. Back in '97 a physics postdoc pal of mine, who had access to a nice precision lathe and the raw materials, made a very heavy polycarbonate platter for his turntable. I got his "pre-production" effort to put on my Systemdek. Yeah, it was great, but I changed the tonearm and cart at the same time, so I'll never know whether the platter made a difference (and I had to shim-up the tonearm base to match, so I couldn't really go back).

Michael Jones, Saturday, 12 September 2020 00:21 (two years ago) link

I’ve got a project carbon and I get motor gum from it. Apparently it’s an issue with my model. I’ve since bought a used Thorens that was cheaper and waaaay better. If you’ve got a good local shop, a used turntable is the way to go.

Cow_Art, Saturday, 12 September 2020 01:29 (two years ago) link

Motor HUM.

But motor gum sounds kind of cool.

Cow_Art, Saturday, 12 September 2020 01:30 (two years ago) link

Oh yeah, there's motor hum with my Carbon too - getting worse towards the end of each side? Or maybe it just manifests itself after 20min+ of use. Anyway, at the levels I listen at (rarely headphones with vinyl), it's only noticeable between tracks. I see there are a few tweaks out there to remedy it; either to do with the transport screws (pretty sure I removed those) or damping the screws around the motor base. It's not as annoying as the anti-skating weight slipping off the notch on the counterweight, which it seems to do every time I go to use it.

Michael Jones, Saturday, 12 September 2020 11:07 (two years ago) link

My Carbon has that hum too. Not a huge deal, but noticeable if you pay attention to it. Pretty much a non-issue once the record starts playing, at any volume. I've also had an issue with the dust cover, stopped staying open on its own after a while, and became increasingly hard to open past 45 degrees. Wound up replacing it with a cloth dust cover.

henry s, Saturday, 12 September 2020 15:28 (two years ago) link

Yes, same here with the bloody dust cover!

I've got a Linn LP12 but it's currently out of action because there is a loose connection in the wires connecting the cartridge to the tonearm. I think I'm going to have to take it to a shop because I have no idea how to fix this or even where to get replacement wires from. this is probably going to cost a lot of money isn't it?

CP Radio Gorgeous (Colonel Poo), Sunday, 13 September 2020 17:03 (two years ago) link

These are the short headshell leads? You can buy some for $10 on amazon. Take a picture of the current connections and match it. You might have to realign the cartridge after if you move it.

bogo jumbo boba (Sufjan Grafton), Sunday, 13 September 2020 19:11 (two years ago) link

might also be able to squeeze the loose connector with some tweezers before slipping it back on

xp you might try turntablelab.com or lpgear.com

maybe worth seeing if a local retailer is a pfanstiehl dealer, which in my experience is a great deal cheaper

depending on the cartridge it might be easier just to buy a brand new entry-level headshell / cartridge combo, in which case you could just plug it in / screw it on and go

Reviews on the pfanstiehl stuff are mixed. My experiences with Tonar have been uh not good. Jico, however, has come through for me in a big way, and I’m glad to buy styli from them for any carts I can’t find OEM styli for.

headshell and cartridge?

bogo jumbo boba (Sufjan Grafton), Wednesday, 16 September 2020 16:03 (two years ago) link

yeah both. I had one that I used for a year, bought cheap cuz my kids broke 2 already. but now that they finally understand that ONLY DADDY TOUCHES THE NEEDLE I don't have that problem anymore. another thing I'm curious about is which setting to use on my receiver. I can't use PHONO because my turntable has an amp so it sounds like blown out garbage. AUX is pretty good, but it can't handle noisier records well (such as Dan Deacon's Bromst). I have it set to TAPE MON now and it sounds pretty good. idk if that's ideal though.

frogbs, Wednesday, 16 September 2020 16:25 (two years ago) link

I think AUX and TAPE MON are likely the same in terms of level

bogo jumbo boba (Sufjan Grafton), Wednesday, 16 September 2020 16:32 (two years ago) link

I've been A/B testing them and in most instances they're the same but AUX seems to flatten the noisier/busier sections. I think there might be some built-in volume adjustment there, with AUX it seems to like to crank up any quiet bits to the point where they're louder than the parts that are supposed to be loud (for example Faust's "Just a Second" - the weird electronic bits in the second half are notably louder than the guitar jam in the first). Maybe this causes strange things to happen when listening to records that are a bit more nuts. As a side note Dan Deacon is a hell of a test for a new speaker set up

As for the new headshell/cart...one thing I was noticing on the old one was that the cymbals & hi-hats didn't sound crisp which I've heard is a sign your needle is going. I'd guess I've used it for around 400 hours which I think is about the lifespan of a cheap one?

is there a way to turn off the phono stage built into your turntable? I had a Sony one with a built in phono stage and the switch was somewhere fiddly, like under the platter mat

umsworth (emsworth), Wednesday, 16 September 2020 20:33 (two years ago) link

one year passes...

About four years ago I splurged on a Speed Box S for my Pro-Ject Debut III so I wouldn't have to lift the platter every time I wanted to switch from 33 to 45. Recently after I moved turntable and Speed Box from one shelf to another, the Speed Box stopped working. It powers on when not connected to the turntable, but when connected the lights flash briefly and then nothing happens. The turntable is switched on as appropriate and works fine with its own power supply. I thought the problem might be a short in the tiny cable that connects Speed Box to turntable, but a replacement cable made no difference.

I don't want to go back to switching the platter all the time, yet I cringe at the thought of buying another $150 thing just so I won't have to. Any suggestions?

eatandoph (Neue Jesse Schule), Saturday, 15 January 2022 01:18 (eight months ago) link

Scrap the pro-ject & buy a TT with a speed selector like every TT since the end of WWII has had?

war mice (hardcore dilettante), Saturday, 15 January 2022 04:45 (eight months ago) link

I don't have any experience with this component, but a search confirmed that others have had issues. Checking the cable was a reasonable thing to do. In most cases, some of the components in the box are fried. If you don't have a warranty or anything else to worry about voiding, I'd open the case and look for obvious signs of overheating. Perhaps, it failed in a somewhat graceful manner and can be fixed.

If you can't fix it, maybe it is a good time to sell the pro-ject and get something with the integrated speed selector. It's a bummer that the box failed, and I hope you find a solution.

Lack of push button speed change sadly very common in mid to high end belt drive TTs. Used to have take the platter off my old Systemdek, same with the current ProJect. My Michell had a free standing motor outside the platter so that was just moving the belt. The idea that a speed switch is an optional extra, or involves buying an expensive DC PSU, is just one of those weird inconveniences that’s become the norm.

Hope the Phono Box lives again.

maybe try contacting sumiko?

Thanks for the replies, even the non-empathetic one. As Michael Jones suggests, the Speed Box seems to have gone into decline since, oh, 9/11. Although the new Debut Carbon Evo actually has a speed button!

I don't think the speed box is covered by warranty, so I'll give a shot at looking inside despite my ineptitude with these things. This hasn't changed much since I was complaining about this turntable upthread 13 years ago -- after the hum issue, I contacted the (now sadly departed) Needle Doctor and they ended up just sending me a replacement, which is the one I have now.

Hi, I received a SL-1500c for my birthday. It’s awesome. What do I need to get good quality rips of my rare dance music vinyl? What cartridge? Amp? Pre-amp? I don’t know anything!

Allen (etaeoe), Saturday, 11 June 2022 15:53 (three months ago) link

Does it have a cartridge on it already? I'd start with the minimal setup and upgrade from there. The sl-1500c has a built in pre-amp if you plug into the "line out" ports. You can buy a 2-channel usb audio interface that takes RCAs as input, download audacity, and you are in business.

If you want to upgrade, I'd guess the best place is at the usb audio interface. The nicer ones will have separate gain on the 2 channels and 1/4"/XLR inputs. I'd focus on obtaining a low noise capture. You can add equalization after capture if needed. But if you'd rather plug in external stuff that gives you a sound you like, that would indeed be convenient. So you might look at swapping phono pre-amp and cartridge.

three months pass...

hoping ILX's home audio hivemind can help me out here. i'm trying to set up a record player with a preamp/receiver to speakers. i'm using the following equipment:

- technics 1200-sl mk2 turntable
- bellari PA550 phono preamp
- onkyo tx-8220 stereo receiver
- audioengine hdp6 passive speakers

the turntable was purchased used off ebay, everything else is brand new. i have everything connected but can't get any sound to come out of the speakers.

- when i plug headphones into the preamp i can hear sound in the left channel, but not the right.
- when i plug headphones into the receiver, it's the same except it's far more faint, like i basically have to turn the volume on the receiver all the way up in order to hear it at a normal volume.
- the ground wire from the turntable to the preamp is bare and attached to the preamp's grounding post. the RCA cables from the turntable are going into the PHONO plugs in the preamp, the RCA cables are going from the preamp's OUTPUT to the LINE function in the receiver, and the speakers are attached to the receiver with banana plugs.

am i doing something wrong or do i possibly have a defective part somewhere? my feeling is something could up with the ground wire from the turntable to the preamp but i have no idea why no sound's coming from the speakers.

how is the sound for CD, radio, AUX?

budo jeru, Saturday, 17 September 2022 18:46 (two weeks ago) link

i think you should start by plugging your 1200 directly into the PHONO jacks on the onkyo and see how it sounds.

budo jeru, Saturday, 17 September 2022 18:50 (two weeks ago) link

Does that receiver have A and B speaker inputs? If so make sure you have the right one selected.

mizzell, Saturday, 17 September 2022 19:47 (two weeks ago) link

If something was up with the ground wire it would most like just produce a hum or buzz. It wouldn’t stop sound being produced.

mizzell, Saturday, 17 September 2022 19:48 (two weeks ago) link

i would definitely start with budo jeru’s suggestion of plugging the technics directly into the phono input on the onkyo.

Tracer Hand, Saturday, 17 September 2022 23:13 (two weeks ago) link

Yes, bad preamp most likely

Sufjan Grafton, Saturday, 17 September 2022 23:25 (two weeks ago) link

update: followed budo's suggestion and plugged the RCA cables directly into the receiver, and it definitely sounds much better now. the bare wire on my turntable is really short so we had to electrical tape some additional antenna wire that we had lying around to get it to reach the receiver. as for the speaker issue, i think i just had the cables in the wrong outputs - played around with it and it now sounds pristine. thanks y'all :)

donna rouge, Saturday, 17 September 2022 23:25 (two weeks ago) link

also uh anyone need a preamp lol

donna rouge, Saturday, 17 September 2022 23:38 (two weeks ago) link

great news! happy listening :)

budo jeru, Sunday, 18 September 2022 00:08 (two weeks ago) link

can you return the preamp? and happy listening!

assert (matttkkkk), Sunday, 18 September 2022 01:32 (two weeks ago) link

The other thing to check is if the preamp and the receiver both have volume controls, make sure the volume on the preamp isn’t all the way down. Usually you would have the receiver volume at max and just use the preamp to control the volume.

Abel Ferrara hard-sci-fi elevator pitch (PBKR), Sunday, 18 September 2022 01:42 (two weeks ago) link

I would probably put the preamp near max, or match volume with other line inputs, and control volume from receiver which likely has a remote.
