Bought a dsp a2 of Ebay. Main speaker outputs not producing any sound. have checked speakers, cables, speaker set up. All other ouputs (front, rear, centre) are functional. Is there any easy solution or have I been taken for a ride??
I also have a similar problem with my DSP-A2,i have no sound from my 2 front or 2 rear speakers,my center speaker works fine.I have checked the sound on the test mode,and the fault is still the same, the A and B switches are turned on and all the speaker cables are connected ok. Any ideas would be greatly appreciated as i.m baffled now I also have a similar problem with my DSP-A2,i have no sound from my 2 front or 2 rear speakers,my center speaker works fine.I have checked the sound on the test mode,and the fault is still the same, the A and B switches are turned on and all the speaker cables are connected ok.

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.

Tip: The max point reward for answering a question is 15.
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.
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.
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.
Hissing or high-level digital hash noise? Undecoded DTS or data bitstreams produce very loud 'rush' sound when treated as analog sources. Is it all sources or just some?
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.
disconnect the cabel of left channel from your amp disconnect the cabel of right channel and put it in place of left channel if the problem goen your problem is in left speaker itself (cabel or speaker).if the problem excit the problem will be in amplifier output stage
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
