SOURCE: Gain on one channel stuck at max

Hi there

Check for a dry solder joint on one end of the vol control(earthy end). This will be causing your problem. The pot itself may actually be faulty to. You can always get stuff like that, just got to identify it. Check soldering to the pot first.

best regards
Graeme

SOURCE: turntable to reciever connections

check the continuity in your cables. you will need a multimeter or something else to check the cables. the multimeter is about $10 or so. other than that, make sure that your turntable is actually giving output and that the pre amp is both recieving and sending(same with the regular amp. and make sure that the levels are up on everything and the speakers connected properly etc. you probably know this already, but sometimes a good, friendly reminder helps. good luck!!

Reverse your RCA input around and see if the problem follows, this will determine if the problem is in the turntable output signal or the preampsection of your amp. If it stays on the same channel, slightly move the RCA that's dropping out signal around. If the signal cuts in and out, you know it's just a weak solder joint on the input rca of the amp. If it does not change, your problem is deeper. Chances are it's a "cold solder joint" on the input section of the amp and would only be a labor type repair and no parts involved. That can be a double edged sword as well depending on how long it takes to find it. If you have to have it serviced, find a local shop that's been around a while, they are likely to be a little more insightful as to the exact problem quicker. Hope this helps

SOURCE: record player does not work

Hi, I don't think the amplifier has a mm/mc phono stage, I think it's an optional item.

You can buy one pretty cheap.
If you need more help , please ask

I have Sansui G-9000, and its phono stages emit a buzzing/distorted sound even if a turntable is not connected. There is also no sound coming from the left speaker (I already tried switching the speakers,...


The Phono section has a very high level of amplification and so the audio input is very sensitive. So a possible faulty/loose grounding of the input can create a HUM which can be due to even a poor shielding of the input from stray AC factors. So you need to check for the these factors that can bring in the hum , you can confirm by isolating the phono circuit and working to the faulty stage.
Also it can be due to a faulty power supply - non filtering in DC- to the phono preamplifier.Finally faulty capacitors in power and feedback circuits can be a reason- check the negative feedback circuit which can be an op-amp with a feedback , check the capcitors here as a higher amplification can also be a reason.- check the preamp IC.

I cannot get the audio from my electro brand turntable (L2650) to work thru my Sony DVD Home Theatre System DAV-DZ170.


Hi,
would you please try to explain how did you connect it to each other ?
and which input you have used on DAV-DZ170 ?
does your DAV-DZ170 have any "PHONO" input ?
it is important to know the existing connection to offer acceptable solution..
Thanks.

Low volume through amplifier


Turntables generate a very low signal. Phono inputs on receivers containa pre-amp section to boost the signal to "line level" or the same level as other audio devices. I would suspect that you need to add that pre-amp section. Phono preamps are available for around $20 or so and are inserted between the turntable and the standard audio input on the receiver or amp.

Hope this helps,
Dan

Is there a way of connecting my ipod to my sherwood cd player?


The answer isn't with the CD player, it's with the amp.
Does the amp have selectable inputs, or does it just have one input for each channel?

If it's a simple power amp, then you'll have to unplug the CD player and connect your iPod to the amp inputs. I'm guessing that the CD player connects to the amp with RCA (phono) connectors like these ones.
If that's the case, you can get a cable (like this one at Radio Shack, but any office supply store will have one too) to connect your iPod to the amp.

Cambridge A5 Amp, only one speaker works when phono selected


If both speakers work okay on other inputs .Then cable from pre-amp to amp and main amp are okay. If phone RCA jacks go directly to electronics board .Then its possible solder on phono jacks need to be resoldered or other connections in that section.If unit needs repair you can also purchase a phono preamp from radioshack hook up your and use it on other good inputs such as CD etc..Please note PHONO inputs are only for turntables .If a non turntable input such as CD,TAPE,TV Etc is used on PHONE .Then you will overdrive this input .

How to connect my qqualizer to my djm pioneer 400 mixer


Use the stereo master outs from the DJM into the A and B Inputs of the EQ (you'll need 2 phono to Jack or 2 phono to XLR cables) then from the A and B Outputs of the EQ to the power amp/ speakers, etc (you'll need jack or XLR cables depending on what is powereing your speakers)

Instruction manual for ministry of sound mixing decks


What are Ministry of Sound mixing decks? I am familiar with MOS, but was not aware they manufactured mixing decks?

Are you connecting these to a DJ mixer, or a Home Receiver?

If it's going through a home receiver, make sure you have them connected to the PHONO input on your receiver. If your receiver does not have a phono input, and you are connecting to the LINE IN or AUX IN section on the rear, you will not hear much. Most turntables require a pre-amplified signal, and only the PHONO input has this option. So, you will need to purchase a PHONO PRE-AMP, and connect your turntable to it, then connect the PHONO pre-amp to the LINE IN.

If you are connecting to a DJ mixer... same thing. Make sure you have them connected to the PHONO INPUT on the mixer. If you still don't get anything, then there might be something wrong with your mixer.

If you could clarify you exact set up, and the EXACT models, we can help you better.

Pioneer a858 amp no sound from phono stage, I bought it from ebay and dont know whether someones connected a line level component to it such as a cd player. and if they had would it kill the phono stage...


Hi Big John

This is a nice reference series amp with a decent phono preamp stage. It is unusual to see a phono stage get damaged in this way.... but Murphy's law tells us "If it can be blown up, then someone will do it". I recommend that you do fix it. First up, perhaps check the settings for the preamp on the rear of the amp(from recollection). Be sure that you have it in moving magnet (mm) mode if you are using a MM cartridge.

Although its been a few years, My recollection is that there is a separate power supply for the phono preamp, with maybe even power regulators on on the actual preamp board. First check would be here to see if both DC rails are present for the phono Preamp stages. Most common failure here is heat stressed cracked/dry solder joints.

You need a good HiFi/Audio tech to have a look at it for you if the problems run deeper than DC supply for the preamp. Good luck. A FixYa rating is a great reward for my time to address your problem. Cheers

Not a good sound


you can't...the technics need to be pluged into phono..because the signal has to be amplified for it to play...phono channels on amps and dj mixers have an amp built in....
