    The display does not say protect and the standby light is not flashing.

Is there an indication of protect mode on the front display? Have you checked to see if the tape monitor switch is on? Did you hear a click when you first turn on the receiver followed by a second click?

    The lack of the click indicates that the output section is not on. This is usually becauise a problem has been detected and to prevent further internal damage or damage to the external speakers, the outputs are disabled. This is called "protect" mode. Many receivers either flash the standby light or display the word protect on the display panel. This particular unit used discrete transistors so the repair is relatively simple. If you are not familiar with electronics repair, get this to a service shop. Expect a parts cost in the range of $20-$40. Add in the local labor rate for the total repair cost.

I have a Vx2433WM and am using it as a tv for my PS3 through hdmi connection. The audio stopped working. I tried muting and un-muting but nothings happening. How do I get my audio back??

I'd check in the control panel under sounds and see what the system thinks the output device is. Probably not the speakers. If not, change the output to your computer speakers.

I just hooked up an AOC monitor to two computers. Sound is working on one but not working on my HP Pavilion. How do I resolve that? I don't have any extra speakers.

The sound goes out of the computer to a set of speakers. If the monitor has speakers built into it, then the sound comes out of them. Each computer must have a connection to the sound card (the little green hole) to speakers. If you want sound from the second computer, unplug the sound cable from the one computer and plug it into the other one.

Dennon DRA 697ci with bose 901 speakers.....just moved to new house....hooked up stereo and can only get minimal output

I assume it used to work. You need to ensure the connections to and from the active equalizer are all proper. I would think you have it in the Pre-Main loop.

It sounds to me like you have an in/out reversal at the EQ or a dead Tape Monitor selected.

Or MUTING is selected on the DRA.

From the remote control ONLY:

Press MUTING to mute the sound through all

speakers and headphones connected.

"MUTING" appears on the display and the

volume turns off (the volume level indicator goes


To restore the sound, press MUTING again so that "OFF" appears

on the display.

• Turning MASTER VOLUME on the front panel or pressing
VOLUME +/- on the remote control also restores the sound.

Hi, i have a nad c325 bee amp and i have a problem with hooking up speakers. I have just the tiniest amount of sound coming out so there's some signal there. I have tried different speakers so i know its...

Before you continue, turn the volume DOWN. If you can't hear it at mid-volume there's no sense in spinning the volume knob higher. You'll only endanger your ears and speakers if you suddenly resolve the switch or whatever is the problem.

Are all sources acting the same?

Check these things (from the manual):

Tape Monitor selected?


Headphones inserted?

Jumpers missing between Pre-Out / Main In?

BTW: the manual is available at

Computer speakers are buzzing

Common humming sounds from computer sound systems stem from the follwing:

1) Interferance with other electrical componants / devices
Solution: EMF / Radiostatic shielding may provide the solution

2) Defective componants
solution: try the hardware in another PC, if it still hums, your board / plug-in compants may be defective.

3) Jack(s) - Headphones / speakers have loose connection
Make sure everything is plugged in securely, and your jacks have not been damaged, also make sure you are plugged into the correct ports.

4) Microphone boost / auxiliary settings
check your sound settings, disable any ports you aren't using. Line-in, Aux, CD-rom, Digital Input.. if they aren't being used, they may be creating "whte" static in the lines. Muting them, or disableing them in the sound settings for your device may provide the solution..

5) It has been known to happen that certain CPU / Case / Power supply fans emmit a sonic frequency through the speakers due to EMF expulsions from the electro-magnetic motor. This is rare, but is possible, Disable the case fan to determin if it's the culprit, swap power supply, or CPU fan to determin if they are the issue.

WARNING: Never run your PC without the CPU fan in full operation, Never run the PC without your Power Supplies fan in full operation: This can lead to DAMAGE to your PC.

On a personal note: My card has several different ports, make sure you are plugged into the correct port, and muting the Aux cleared the humming in my computer's sound system.
