balanced volume control

diy student · 15th January 2002, 09:37 PM

Could anyone recommend a good reasonably priced balanced volume control. Does this mean the control must have four poles or six. I can't afford the $200 dollars to buy some of the attenuators I've seen such as the shalco. Any suggestions would be welcome. Thanks.

Some of the others may scream, but think about some of the MDAC volume controls, specifically the TI/Burr Brown PGA2610 or Crystal Semiconductor CS3310. They have 2 matched sections which would work well for balanced volume controls. You can get parts cheap: most companies will give you a piece or two as engineering samples

Definately cheaper than $200, but these two devices are serially controlled, so a microcontoller would be convenient.

Although the description for these ALPS pots say 2 ganged, they actually have 4 ganged sections...and they're dirt cheap. They even have a motorized version...check their site under potentiometers.
