Acoustic Research Model AW871 wireless sterio speakers

I just purcheased these Acoustic Research Model AW871 wireless sterio speakers and a ONKYO Model TX-SR504 AV receiver. The Acoustic Research transmitter has an audio level indicator light which should flicker intermittently if there is a good connection to the wireless speakers. But the light does not blink or flicker for me - nada. The speakers each show a blue light which means they are picking up a signal from the transmitter, but no sound. Everything is plugged in correctly for power. The AR transmitter comes with a "Y" adapter cable with metal connector plug-ins on the ends for an analog connection. However the ONKYO receiver accepts only bare wire connections for its speaker outputs. So I cut off the metal connector plug-ins, stripped the wire back 1/2" and inserted it the terminal posts for "Front Speakers A." My audio source is a CD player which is plugged into the receiver. The receiver setting are set for CD input and front speakers A output. I am not getting any sound from the wireless speakers and no audio level indicator light on the transmitter. What am I doing wrong

    Thanks Dyllan. Actually I found out that the RCA plugs for speakers have two wires, not one. You can see that I am not electronically literate. So I rewired one to "+" terminal and one to "-" terminal for the right speaker and for the left speaker and it worked. Then I discovered that the original RCA plugs (I had a second set that I did not cut) actually work better in the "CD Out" on the back of the receiver. The "CD in" is for the plug coming from my separate CD player.
    All is well. Thanks.

Your connection between the AR transmitter and the ONKYO receiver sounds solid. I'd guess it's the wireless speakers that are the wrong point, or at least that's what I'd look at first. Doing a bit of research, I noticed a couple minor points. First, these seem prone to RF interference from other RF devices. Have to tried switching channels on them? Second, someone reported theirs would not work properly unless the speakers were turned on just before the transmitter, and turned off shortly after the transmitter. Apparently you have to hold the button on the front in for 5 seconds to turn the speakers on or off. I know that's rather basic, but it's been a few days and no one else has responded, so I figured we should start somewhere.

Perhaps you just use a cable like this:

Wire Kenwood GE 7030 equilizer to onkyo tx sr504 receiver

The manuals explain it.

For all practical purposes an EQ or any analog audio processor connects exactly like a Tape Deck - into any RCA pairing that has both an OUT and an IN and can be selected to be in or out of the audio path.

However, on this and just about any modern digital-capable AV Receiver, activation of any external loop that would connect a processor or tape deck would automatically DISable any digital audio sources. The effects of the processor, therefore, can only be used with analog stereo sources. It WILL affect the sound going to all speakers if you use the various Digital Sound Porcessing modes as the extra channels are derived from the stereo channels anyway.

How do I adjust the balance on my onkyo receiver?

You don't. Once the speakers are adjusted relative to each other using the test tone that's it. The modern presumption is that you're sitting in the sweet spot at all times and all program material is perfectly recorded.

The manual is available at for free.
