Question about Yamaha RX-V690 Receiver

1 Answer

Balance control I am currently only using this as a stereo amp. I have to turn the Balance control to about 8 o'clock to get equal volumes from the left and right speakers. But, when I set the Balance Control knob to 12 o'clock and use the Test function/button via the controller, the volumes in the left and right speakers seem equal in volume. I have tested/ruled out each audio device connected to the amp that gives the same balance problem.

The channel that is weak will either have a faulty transistor or a bad capacitor on it. Most engineers would test it by injecting signals into the circuit at different points. Working backwards from the front end. When the signal goes weak, you have found the faulty stage.

SOURCE: Left front main speaker level drops after being on for a few hours

Run the speaker test mode :

While running the speaker test tone to balance your speakers, you cannot adjust the balance of the Main speakers independently. The speaker test allows you to balance the sound (dB) levels of the Center speaker, Rear Left, Rear Right speakers to match the level of the main speakers. So, the first thing you do is press the [TEST] button on the remote. Next, adjust the [MASTER VOLUME CONTROL] until you can adequately hear the level from the main left and right speakers. Then, as the tone travels clockwise to each speaker, listen carefully from your main seating position in the room to determine which speakers (if any) need to be adjusted in level (either up or down) in order to balanced the sound to the main speakers output. Then adjust the Center, Rear Left or Rear Right speakers accordingly until the proper balance of level is attained. If you would like to change the level between the mains, you can use the [BALANCE CONTROL] either located on the front panel of the receiver or in the Set-Menu. A common challenge people have is that they try to adjust the main speakers to match the center or rear levels. If your center speaker is louder than your mains, You cannot adjust the main level up, you need to adjust the center speaker level down. All speakers need to be adjusted to match the main level.

SOURCE: we want to hook up

Without a huge mess, I would suggest one of the multi-speaker selectors that sells or a similar item.
Just put "speaker slector" in their search engine.

If youre going to 8 other might try a couple of wireless speaker systems too. They work in stereo and wires

SOURCE: Yamaha RX-V1000 volume control erratic, remote


The volume knob issue alone sounds like it's hardware-related and therefore not easily fixed. Also, since the remote appears to be working (the LED's are lighting up), but the unit is not controlled anymore, the IR sensor is probably faulty as well. I would seriously consider sending this AV receiver in for repair. If it's still within warranty, you shouldn't need to pay anything for the repair.

Manual for your receiver:

It's not much but I hope this helps.

Direct monitoring, plugging headphones in, the right side is quieter than the left side.

You have to slide the switch on the front of the mic to the Mono position. You're monitoring in Stereo mode, which is only for when you plug a stereo cable into the input jack of the mic.

When using the microphone itself, always put the Monitoring Switch in Mono mode.0a08a992-b4ca-4d4e-af74-53f7136ceeb0.jpg

Volume balance between the speakers as there doesn't seem to be a balance left/ right switch.

Check all of the connections affecting the two channels. Speaker wires, inputs, outputs, etc. A poor connection can have resistance that will affect proper balance between channels.

Also check your volume and/or balance controls for proper tracking. With the unit completely turned off, turn the volume control many times from extreme counterclockwise position to clockwise position. Ditto for any and all speaker switches. If none of these steps clear up the anomaly you have a difference in gain between amps responsible for unequal outputs and the unit will need to be troubleshooted for bad cap and/or resistor causing the anomaly.

Audiosource amp 100 on lower volumes right speaker louder than left speaker 2.1 setup

The problem is not due to how the circuitry is configured; the problem is due to failure of some element in the right channel amplification circuit. This will require detailed troubleshooting to correct.

The volume jumps up and down when i turn the volume up .also the balance tuns completely left on its own

Years ago the volume and balance on amps were on seperate circuits. But these days they are on one. It sounds like this problem is all down to an IC in the pre-amp stage. If you trace the connection from the volume control to the PC board you will find this chip. If you come accross more than one, put the code numbers into Google and see what they do. If you see one the at deals with volume and balance, you have got the culprit!

HI , just found your post . I also have just picked up a denon DAP-2500 pre and 2 POA 4400 amps with klipsch belles, having same probs with power balance i followed some helpfull advise and deoxidized all rca jacks speaker terminals ect. also i opened the pre amp and cleand it even though it was fairly clean, i used cleaner on all switches and volume controll's . WOW I could hear it nice and clean . Next i will clean the amps. hope this works for you as this is great equpment well worth saving.

Alpine 9845 cde head unit car stereo i Cannot figure out how to access the Fader not the balance,altho i havent seen that function either. ive been to the alpine site and they dont even mention it. im sure...

Press the Rotary encoder (CDE-9845/CDE-9843
only) or press MODE (CDE-9841 only) repeatedly
to choose the desired mode.
Each press changes the modes as follows:
BASS: -7 ~ +10
TREBLE: -7 ~ +7
Subwoofer : 0 ~ +15
Balance : L15 ~ R15
Fader : R15 ~ F15
Defeat : ON/OFF
Volume : 0 ~ 35

NAD 302 stereo balance problem

I would replace the output transistors of the bad channel and any very low ohm resistors associated with them.
Whilst youre in there replace the electrolytic caps in the power amp section. Caps are cheap and plentiful.
I dont know what the rest of the circuit looks like but there might be a need to balance the DC offset after replacing transistors. and carry many good replacement transistors.
