Question about Aiwa AV-DV75

1 Answer

Speakers stopped working.

Well I use my av-dv75 for surround sound on my Xbox 360. Up to this point I had full surround and bass. I turned it all on the other day and noticed that only the left front speaker had any considerable volume output. The sub has also stopped working. I can get the sub to make noise by touching the connector wire so i know it's not blown. The rear speakers also make static but no actual game sound. The front left and right work perfectly still. What would the problem be? This all started without anything on the unit being changed... just happened. And I don't ever turn it up past 15.

    Connecting the wire to make a noise is a bad thing, but is it full volume when you do this (I assume you mean connecting directly).
    Does the unit have multiple inputs? (aux in or l/r stereo in?) If so it may be worth trying them if you have the cables... that way you can see if it passing sound through properly to the speakers...
    At a guess it sounds like there is a problem with the amplifier, loose wire/burnt out internal connector etc. since one speaker works and you claim the others don't work.

More than likely you have blown outputs, as the sound you hear when you touch the leads to the terminals is the DC offset of the power supply being routed through your speakers...accordianman

Do large speakers have to be in front


This being a generic question, I can only provide a generic answr:

In multichannel rigs the question of Large vs Small denotes nit the 'size' but the ability to handle bass - Large presumed to be bass-capable. When you identify a particular speaker as 'small' in an AVR you're telling it to redirect bass to either the Subwoofer or the Main Speakers if they are 'Large'. Some AVR's also allow sharing the bass with the sub instead of having it all go there. If you have large speakers configured for bass the realism of surrounding bass sounds is better.

You can have many combinations of Large vs Small speakers in most AV setups but there usually are some dependencies. For example, bass can't be directed from one 'small' speaker to another; or if you select 'small' for the front speakers a Sub is presumed to exist.

I have all large speakers in my set.

New Yamaha AV Receiver and Tannoy Speakers muffled weak bass only


Maybe some wire is faulty... Try to disconnect everything and connect each speaker one by one, first trying only radio tuner and then trying to connect the TV and other devices. Using that you can isolate the fault into the specific component/wire.

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.

Broken receiver


I bought my AV-DV75 from Best Buy about 10 years ago and it still works. However it did stop working a while back. I don't know why. I alsmost threw it away. But I unplugged it for a couple of days, then plugged it back up and it came back on. It is still working. Maybe that will work for you.

PS
my center speaker quit working recently. If you decide to sell your AIWA speakers will you please email me?

AV-DV75 center speaker works surround speakers do not


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.
