Question about Aiwa AV-D50 Receiver

1 Answer

Center, surround speakers not working. "Can't Use" message for DSP.

We can't seem to get the center and surround-sound speakers on our Aiwa AV-D50 working. All the speaker types are right, and we have everything hooked up correctly into the back of the unit, and the back of the speakers, checked and double-checked. (position, pos/neg, all that.) The left and right speakers, as well as the subwoofer, are working just fine. Another problem, perhaps related, perhaps not, are our DSP buttons. For some reason, we get a "Can't Use" message, no matter which setting we press. Dolby Surround, Live, Arena, etc. It was working fine before we moved to a new apartment and set everything up again, but we can't find out what we've changed that might cause that error, or how we can fix it. Can you help? Any assistance is appreciated.

Sounds like the old stuck button thing after a move??? What i mean it go over all the push buttons and maybe you will find one that is not pushing in and returning??? If alls ok then you should check the obvious like bent shafts or balance controls ect. ay have jogged something inside and you will need to see a pro to assit you unless you know how to trouble shoot solid state electronics?? These units have no real serviceable parts inside. Check with your owners manual for the sevicer nearest you. If they are not listed call the service # or try 1-800-289-AIWA . good luck

The STR directs sound to the center as instructed by its speaker setup. You say the center does not work on calibration. Is it defined?

Prove another speaker does or does not work on the center output. Then we'll know if it's the receiver or the speaker ensemble that has the problem.

Have you checked the manual for this "
There is no sound, or only a very low-level sound is heard from the center/ surround. "?

Is model AV-D75 compatable to AV-D50?
Compatable [sic] or comparable? Everything is compatible to some degree, but one doesn't often link AV receivers to each other.

The AV-D75, according to what little I could find, is a circa 2000 unit that does NOT some things the AV-D50 does have:

BBE processing
Super T-Bass
Graphic Equalizer
5.1 analog inputs
Numerous DSP modes

Only front and center speakers work, not surround.
If by white noise do you mean the test tone generated by the receiver? If so, this is actually pink noise and it is internally generated by the receiver. I would make sure either in the menu or on the remote that you haven't accidently turned off the surrounds and double check the wiring to the surrounds. Good luck.

Hi there, i have a Kenwood V7090D AV receiver. the problem is a) i cannot switch the DSP off without 5.1 switching off as well and b) DSP affests all channels when speakers B is swithched on. if u can...
If you have only Left and Right connected the receiver wont know what to send to the other speakers without some kind of DSP.
If you are using an optical or coaxial connection from a dvd player it may utilize the other speakers if the DVD player is providing that information.
If you dont like the DSP but still want to have all the speakers function while listening to non surround sound material try setting the DSP flat or to a reduced setting.

If you are listening to a DVD with surround sound information and the DSP off still provides no sound to the rear speakers check the manual for that receiver for a "auto surround detection" setting.
good luck.

If all others had been fine before this problem arose, and you are sure that you haven't changed anything in your amplifier's channel selection menus, the problem might be deeper to solve! Try these out; 1-If the amplifier has a test menu to check out all channels plugged in, activate it. You must be able to get sound, which is like rustle, from each speaker. 2- Check your plugs, cables etc. be sure that there isn't any short circuit 3- Grab your amplifier's remote control and find the "channel selection menu" that allows you to increase and decrease volume levels for each speaker independently.
