Hi danjan

Sounds like you have a faulty master level control, or dry solder joints connecting it. There are a few things that you can do to sure this. .

  1. Pop the unit apart so you can get access to the control solder side of the printed Circuit Board.
  2. First, visually check the soldering to the control where it connects to the board,
  3. If soldering to it looks ok, then try a squirt of CRC 2-26 contact cleaner lubricant into the internals of the master control.
  4. Before replacing it you need to be sure that the pot is faulty is to look for audio in the center wiper of connection of the control. You will need some test gear to pursue this level of diagnosis
  5. If you have audio in and out from the pot, then there is a failure after the pot in the summing amplifier stages. No audio into the pot points to the stage prior to it.
If you have no experience with this sort of repair work to high density surface mount circuitry, then I strongly urge you get an audio tech to have a look at it for you;:) This sort of repair expect to set you set you back $40-80 across my workbench, depending on what needed to be done. Good Luck

SOURCE: the volume knob is flashing red on my AX-SD1 amp..no sound.

Unplug the receiver, let it sit for a minute or two then plug it back in. It's either in "mute" or in Protection. Generally, Yamaha's will say "Ck. Spkrs" If it still has a problem, post a comment and I will look up some sources and help some more.

Best place is at the head phone jack. or get a head phone to rca adaptor at The Shack or on the web. Then you don't even need to take the cover off or solder.

It is possible then that the root cause may not be electrical, but acoustic if you're noticing the issue from your listening position.
If you can run a channel test signal identically one channel at a time by positioning your meter less than a foot away and exactly the same distance with each speaker and the level differs by more than 1/2dB, then it's not the acoustics.

My sony xplod 1200 whatt amps red light keeps coming on all the wires are good when it gos to hit it gos red


check your ohm load on the sub and see if your amp can do the same, That is why every time it shuts off into protection mode. Check your gain level on the amp to this is not a volume knob for your amp, It is to get both the amp and cd player on the same page. Hope this was helpfull

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.

No volume control on Velodyne SPL12BV sub amp


If my memory serves me on this amp, the volume control is actually a chip in the pre-amp section.

You could try and replace the actual knob on the panel and see if that fixes the problem.
If not, you will most likely have to send the amp section back to Velodyne for repair.

If you do send the amp back, use some masking tape and mark the speaker leads. Hooking these back up wrong will blow the driver and the amp.

My amp won't play distortion.


Hello all you have to do is turn your master volume down to just barley on then turn your pre amp volume somwhere about 2:oclock depending on how much distortion you want ajust your volume on your guitar a little past halfway to give yourself some headroom in case you need to turn up some while you are playing! just think of it as your guitar is your first pre-amp then your amp is second preamp in line ,that is your over drive ,then the master volume is how loud you want the overall volume i hope this help's ya!

Amps and sub-woofer not working


Enter into the Audio Setup mode(press and hold volume button for at least 1 second). Next, repeatedly push the volume button until the display shows "2 ZONE". Make sure this feature is turned off. Hold the volume button again for at least 1 second to leave Audio Setup mode.

Now you need to make sure the Subwoofer Output is turned on. Do this by holding down(AM position) on the control knob(toggle stick) for at least 1 second. Each time the button is pressed, the Subwoofer Output is turned ON/OFF. the display should show "SW ON".

Next, you can go into Audio Control mode(press but do not hold volume button). Keep pressing on the volume knob until "Sub-WLevel" is displayed. Here you can adjust the amount of gain for the Subwoofer ranging from -15 to +15.

I hope this fixes your problem with it.

Cheers
