I have purchased a peavey pv 6 (not the usb) and I have a squeal problem when I activate the tape to mix button and rising the master fader to 0 and my headphone volume. I am using a creative soundblaster external sound card. my connections are, mixer tape out to sound card line in and sound card line out into mixer tape in. I have no problem when I don't use the tape in of my mixer or pushing the tape to mix button. Do I have a wrong connections?

Contact Peavey Customer Service. They can email you the schematic, and you can get the part directly from them.

what operating system are you using?

Kinda hard to tell you exactly what the problem is. Your current power supply may not be able to give you the amperage you need even though the voltage is the same. You can get the correct power supply on Ebay.

PV series mixers from peavey suffer from horrible sliders pots quality, so be prepared to change that pot, it is pretty easy to change, real difficult comes out when you are trying to reach it, let me know a bit further to help you out troubleshoot accurately the issue.

With the headphones plugged in, and the headphone level turned up you should be able to hear whatever is coming through the main mix. If you cannot hear anything, make sure the buttons marked 'TAPE TO CTRL/ HP' and ' TAPE TO MIX' are not pushed down.

I would expect the numbers are on the installation disc, not the hardware. Also check labels on the original box it came in.

Several things to do: Plugging into the tape type inputs... say the 7/8 channel.

The little button below the set you plug into needs to be pushed to the down position. This selects the "B" set which are the RCA jacks.

Below the set you are plugged into. Turn up the top knob "Gain" until the "clip" LED just isn't quite flashing.

At the bottom of that same column Turn up the "level" as needed for the mix.

Then of course, advance the Master level as needed.

Hi there,
you can run one amp from the main out puts and the second amp from the CTRL Room out puts. The CTRL ROOM are outputs that are linked to the same bus as the master fader. This will work fine...
Best of luck

check for cold solder joints from the input jacks and the fader. If any look suspicious (dull or grainy) re-solder.

its obvious that the fader in question needs replacing ..parts are available from www.peavey.com
