Aiwa Shelf system volume control doesn't work right
Apparently (I believe it is the same type of volume control on most of these systems) the volume won't go down when knob is turned counterclockwise and vica versa. I have to spend a lot of time turning the control both directions just a little bit to effect a volume change, usually not to a level I want. Is the volume control defective? It does not act like a standard volume control that has stop detents at min & max levels. This is an international version as my son purchased it in Germany and it has dual voltages plus dual AM channel spacing for Europe and the U.S.

Hello. I had a similar problem with my AIWA ie. erratic control of volume. I found a how-to on youtube which describes how to take apart the volume control, clean it, and put it back. It now works fine. For me, the tricky part was getting to the front face of the PC board.
On most TV's with speaker control there's a way to disable the TV's volume control effect on the level fed out to an external amplifier. Find it and disable it it or select FIXED for its level, or, while listening through the Aiwa, raise the TV's volume through its own remote and see if that affects what the Aiwa gets for volume.
Or, enable the TV's speakers but find the same interna lAudio setting and make it Fixed, but turn the TV volume down if you don't want to hear its speakers. That way, you could actually listen to the TV on its own speakers if you want, say, for casual watching of the Weather Channel or news, for example.
The "volume control" on your Aiwa is in fact what is called an "encoder". These can fail. They work in concert with the microprocessor to control the electronic volume control IC. Yes this part can be replaced. Try calling Sony with your model number and request the part number for the volume encoder. They should be able to help.
I'm sorry but I don't have a listing for that model number. Many of hte Aiwa units use what is called a digital encoder. A call to Sony with the model number should get you the part number as well as the cost and availability. Aiwa is a brand of Sony.
Normal Aiwa compact shelf units use what is called a jog switch for the volume. Usually you can tell the difference if when you you turn the volume up or down. It goes a short distance and seems to spring back. In this case there are two momentary contact switches. One for up one for down. With a plastic lever on the back of the knob that bumps the approriate switch whether turning down or up. If the lever is broken it will bump up against one but not the other. If it is broken plastic you know how good gluing plastic goes it never seems to hold.
