Speakers not working

I have configured all the speakers (5) on the TX-SR504 receiver and when I test them they all have great reception, however when I click off test the front right and the left surround speakers do not produce sound. Can you tell me what to do?

Hi! I have purchased a JAMO S608 HCS 3 and a SUB 650 using an OKYO TX-SR508 Receiver. I can't set it up correctly. When I played music I've heard a lot of bass, I think there are some high...


The TX has speaker setup and test tones for setting the balance and distance with test tones and proving the hardware works. If that all works the difference is probably external or settings.

What is different between the music source(s) audio and the HD movie source(s) audio? Ask yourself, how would a sub make high frequencies go missing? It can't.


Your other speakers are responsible for conveying the high frequencies.

Hi, what causes hums from speaker is when there is no ground shield from either the power supply or from the cable you plugged into the socket from the power supply.

So you will need to check that out and replace untrusted cables for connection..

If after doing this troubleshooting exercise, you will now need to test the speaker with another set to be sure the humming sound is not coming from there.

I guess that will Do.

Have a nice day...

you're going to need a ohm meter (good electrical testers have them) and make sure ohm ratings from speakers match the ratings for your receivers. Sounds like to much resistance for receiver(s)

I have a Onkyo TX-8222 receiver. Sound is ok for music but voices are very low. When two voices, one is very clear abd the other very low. What is the problem ?


You don't say what source(s) are affected. I'm guessing TV or Cable-TV is the problem because music with vocals has voices and you say it sounds ok. Your speakers have no clue whether a sound is a voice or music so that lets THEM out and your receiver doesn't know or care either.

In the modern multichannel world it's usually assumed your electronics are multichannel. This receiver is old-school stereo.

The Center channel is usually where voices are found but some systems (like yours) don't have a Center speaker so they have to be configured to share the Center duty with the front left and Right speakers.This isn't possible or even normally necessary in your case. WYSIWYG

The audio coming in from 'wherever' should be correctly mixed to 2-channels at the source or you'll probably be missing something. I'd look higher up the audio food chain for where the voices are being attentuated. If a cable box is involved I'd look at its audio settings regarding stereo mix-down

Wait, I just had an inspiring thought. Centered voices being mono in nature would partially cancel out if your two speakers were out of 'phase' with each other. Bass would also suffer. Make sure your two speakers are wired identically regarding the red and black (or plus and minus) conductors. If turning the Balance control fully to one side makes bass of voices sound louder you probably have a phase mismatch. Reverse the wiring on either speaker to match the other. There is no absolute right or wrong for phasing as long as they're all the same.

Cerwin Vega SUB8...how do I connect


grady66,
We will start with the easy one, Phase. The phase selector is a setting that can be adjusted by sound; which one sounds better? Either one will work fine. It's mainly for situations where the sub enclosure is located at a distance or behind the listening area. The 'in and out' crossover selector and the input from the receiver goes together. The 'in and out' crossover selector is asking if you want to use the internal crossover to block the bass from getting to the satellite speakers. Most home surround sound receivers only have the one sub out and most subs have both left and right inputs. When there is a single signal being fed to the sub you use the subs left input or buy a splitter and send the signal into both left and right, but either way will work equally the same.

There is two ways to connect the speakers to the receiver.

1) Cross-over 'In': you connect the output speaker wires from the receiver to the speaker inputs on the sub and the speaker outputs on the sub to the satellite speakers; the sub will get its sound from the input speaker wires.

2) Cross-over 'Out': you connect the sub to the receiver using the receiver's single sub out, then connect the satellite speakers directly to the receiver's speakers outputs; in this configuration the satellite speakers are given a full range of signal including the bass.

I have used #2 with the same system and had great results.

How to hook up bose series 2 eq to onkyo tx sr 875 receiver.?


I wrote most of this for a different receiver, but if you account for minor differences to your receiver this will work just fine.

There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.

The good news. I have a setup similar to what you want to do and it works great! I see on the SR875 there are Pre Audio OUTS. This is easy.

A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.


Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

How do I connect my bose 901 active equalizer to a onkyo tx-sr506


AV receivers are notoriously incompatable for Bose 901s. The problem is the EQ charges the entire system and could damage the surround processor. Some higher end AV receivers, including some of the newer Onkyo models have pre out power in inputs on main or all seven channels.which you could install your EQ directly between pre amp & power amp without damaging processor. You can also add a two-channel amplifier to the pre out jacks front channels and use your recever's remote to control volume.
