I upgraded my spent capacitors for higher power IE: 30 to 50, also found a crack in the 16 pin amp chip. works like new. the capacitors are slightly under powered for most 100 amp systems and they fry like batteries left in a flashlight. The parts can be ordered online and they are noticeably bad upon visual inspection. if electronics is not you forte seek an electronics nut and they will be able to download specifications and schematics to replace parts. The capacitors seem to be the most common meltdown and only cost a few dollars online. just get the description on the existing capacitors and then upgrade the power rating for higher peak performance.

    Ps. capacitors hold a charge and need to rest or be discharged before attempting to replace. Caution must be exercised.

How to set-up the audio. I have 5 speakers and 1 subwoofer

It's all explained in the manual.

Your subwoofer needs it's own audio power (amp). I'm pretty sure the manuals for the speakers cover their requirements and set-up.

My receiver is not picking up the subwoofer, there is noise coming from the sub when I'm playing with the conection. The speakers are working and im getting prefect sound from them Please help.....

It would be helpful to know if this is a new problem on working equipment or a new problem on NEW equipment. And if you've flipped through the manual without success.

Of course you KNOW the sub must have its own amp, right?

First, you need to determine if the Onkyo or the unnamed sub is at fault.

At the Onkyo, check to make sure you have run the speaker setup starting on Page 40. If that doesn't work...

Disconnect the subwoofer pre-out at the Onkyo and move it to the VCR Out, tune an FM station and be ready for some real loud subwoofer output if your sub has no volume control of its own. If you can hear the sub, it works and it's back to the Onkyo. If not, the unnamed sub

I can't get sound from my speakers. I have a Sharp Aquos 60 inch tv. Hooked up to my Onkyo TXSR608 Receiver. I can't get any sound from the speakers.

Some Onkyo receivers have support for speakers in different rooms, or zones. Make sure your speaker is not set to send the audio signal to Zone B.

Hello what is the best setting for ps3 slim when played through onkyo 608 pcm or bitstream at the moment it is saying multichanel on the amp if i change it to bitstream it says on the screen some audio...

Bitstream will pass the HD digital audio directly on to the receiver, in either DTS or Dolby format. This allows your receiver to decode these formats. The Onkyo TX-SR608 is capable of decoding all the new HD audio formats, and has quality Burr-Brown digital-analogue converters so it would be a shame not to use bitstream in my opinion.
Electing to output the sound as PCM will utilize the PS3's internal digital audio decoding, and I believe output a two channel analogue signal... which your receiver will then reprocess into simulated surround sound... not ideal really.

Best hook- up Polk psw10 sub woofer to yamaha rx-v663 receiver

You will not need to y connect your subwoofer, if you have only one RCA sub out on your receiver the other end of the RCA connector cable goes into the left input on most powered subs, there is no loss of signal, the option exist as some receiver do sport a double RCA sub out.

Barely hear subwoofer

I had the same problem initially, but going through the auto speaker setup, the receiver boosted output to the subwoofer to compensate. Seems ok now.

Onkyo TX-SR304

Onkyo offers access to manuals at their web site. HERE is a link to the receiver line.

Personally, I'd connect the speakers to main left/right. The subwoofer to subwoofer out. The Go VIdeo unit to VCR/Video 1, the cable box to Video 2 and the video output to the Sony TV composite input. No need to connect the TV audio out to the receiver since the audio feed comes from the cable box.
