It could be that the couplers between pre-out & Main-in are missing
On the back panel, to the left of the Main speaker terminals, there is a set of 10 phone terminals with the label 'Coupler / Output' above.
The 4 terminals below the word 'coupler' should be joined together, left to right (or pre-out to main-in) with a small horseshoe coupler which plugs into the phono sockets, effectively joining them together.
Without these couplers, your front end main speakers would not work as the amp thinks you are using a power amp to run the main speakers and not this amp.

My receiver no longer produces sound to the speakers unless I push the "Pure Direct" button.

verify that the optical cable (or the tv optical output) is not the problem. try using a different audio source with optical output such as a cd player if you have.

Yamaha A-960 amp hookup instructions

The inputs and outputs have to be connected accordingly.
first of all check the speakers and connect them one by one while checking the terminals for the rear/.main and frint speakers. Connect the ouput of the sources, be it the CD, VCR, etc., to the respective inputs marked. You can use the optical cable for the DVD or Blueray.
Now switch on select input and set the tones.
Please give me more inputs if the tips are not enough.

No sound. Tried disconnecting/reconnecting all input/output HDMI cables. Only computer is connected via RCAs (for sound only). No sound at all. Audio works on HDTV, which is going from cable box,...

Did the speaker relays light up ? and did you hear the third speaker relays ON clicking sound? If both no, DSP problem. If both yes, DIR problem. If the speaker relays lit up but NO speaker relay clicking sound, check relay driver +24V power supply.

My yamaha DSP AX1 amp does not work when audio is connected via optical or coaxial any suggestions how to correct this. no sound comes from any speaker except the subwoofer.

Are all the speakers turned off (set to None) in the speaker menu.(except the sub)?

2 channel direct analog stereo may still work, but any surround modes will use the speaker settings and the full DSP digital section.

Check also the input mode isn't incorrect - although if the sub is wired correctly and gives sound this can't be whats wrong.

I want to connect YST-Sw1500 sub woofer to the AX-596 amplifier .How can I do the connections .

on ur subwoofer u will see HPF output, connect this output to MAIN IN of ur power amp (first remove jumper between pre-out and main in from ur power amp) connect pre-out of ur power amp to input 2 L&R (Left is also for mono input). the HFP selector switch will cut off 80Hz or 100Hz to the main input depending on the position enabling u to have high frequency sound on your main speakers. connect the speakers to the main output terminal of ur power amp. do not connect speakers on the woofer ouput.
make sure u are using the right impedance speakers. do not switch speaker impedance selector while the unit is on.

Rx-v463, no sound from rear speakers, and hookups

Sounds like an internal software issue dealing with this may have to return it to the manufacture for this repair.

No center main volume

Make shure your initial setup on the amp is for center as an active speaker,then to check volume on center at zero. Possible to check speaker and wires for open or short.BIGRED
