Gain on one channel stuck at max

On my NAD 304 ampilfier, one channel is stuck at maximum gain, even with the volume knob all the way down. The other channel seems to work fine. I've checked the RCA connections, and tried a few different inputs (CD / Tape specifically). The problem seems to be in the preamp section, as if I connect an external preamp to the amp section, things seem to work OK. Is this something reasonably common such that I'd know where to look for a DIY fix, or is the amp ready for the bin?

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

I have a Behringer 1002 mixer. Applying 0 dBu unbalanced to the input I need the -10/+4 control in its most sensitive position to acheive 0 db out with the main output control set at 0 dB. Is this cor


Depends on the input you are using. First you need to calibrate signal coming in with the Gain attenuation knob. Setting this prior to adjusting your channel output volume should calibrate the signal so when the channel volume knob is set to 0 and the Main volume is set to 0, the meters should indicate a true 0 reading.Not setting the Gain correctly will affect this. On the 1/4" channel inputs, you have less adjustment and may have to adjust the item you are plugging in from its source. If you are having issues with high gain, chances are it could be a cable issue, or something from the source itself.

Play mac through Fender Frontman amp


Simple: connect the headphones out (3.5mm jack) to the input jack of your fender (6.3 jack). By doing this you will loose one channel so you better generate a mono signal inside your computer before. Electrically this is no problem, nothing will be damaged. Turn the gain and volume knobs down and apply a signal from your Mac. Gently increase gain and volume. Et voila wonderful mono sound through a guitar amp

How do you connect power amp to av


I presume you want to use it to drive speakers from a source controlled by the Denon??? Probably the Front channels? We'll assume that's it...

Run RCA cables from the Pre Out jacks to the NAD's L and R inputs. If it has a volume control, set the NAD to its maximum volume (for consistency *), run through the setup for levels and you're done.

* If it doesn't have a volume control it's already set to max. That's normal for power amps. Your receiver / preamp controls the volume fed to them.

BTW: If you're thinking of using two sets of Front channel speakers simultaneously you'll have to choose a level on the NAD that will match up with the others in volume.

Fender Deluxe. The volume knob has no effect whatsoever. Volume only changes with the drive knob.


Your amp has two channels - "normal" and "drive." When you are on the normal channel, the "volume" knob controls your gain. In the "drive" channel, the drive knob controls your gain. In both channels, the "master" knob limits how loud the amp will get.

Most likely, you are on the drive channel, so the volume knob will have no effect. Try pushing the "channel select" switch. You should notice the channel indicator lamp (next to the drive knob) turn off. When it is off, you are in the normal mode. Yellow = drive, and red = "more drive."

Experiment with different settings to get a variety of tones.

To get the most out of this amp, try reading the manual, available online here:

Have fun - it's a great amp.

Sound through one channel


Only the right channel had a sound,the left channel is mute, whatever adjustment you did and whatever balancing you done nothigs happen,even you interchange the speakers. The problem is in the power amp. The STK IC there is busted already, it's better to change it with a new one so the performance become normal again.

I have a PVX 20 preamp by gemini. the volume knob doesnt seem yo do anything. what is it suppose to gain?


Hi there - did you ever solve the problem? I have one of these and it only seems to have a gain of about 5. As long as you're taking your output from 'Pre Out' 1 or 2, the volume control should adjust from no output to max.

Alpine mrp-350 amp


1) If you bridge on a non bridged amp your sound will be horrible as they sine waves comming out of the two teminals will be different... I suggest removing the bridge. 2) The gain knob is to adjust when the amp will reach its max volume with respect to the sterio;s volume. 3) the LP filter is a Low Pass filter and its purpose is to eliminate the higher frequencies that do not sound all the well when played over subwoofers.
