Hi everyone,
I have a set of satellite speakers and subwoofer made by Cambridge SoundWorks. The subwoofer has an amplifier built-in, and connects with a cable to any stereo headphone jack or RCA line out jacks (through an adapter). The cable has a simple inline potentiometer to adjust volume, like an attenuator.
I would like to replace that potentiometer with an unit with digital control of the volume, Mute and Power on/off setting, which should be operated via an infrared remote control. The idea is to connect the speaker set through this unit to any audio source (like VCR, or satellite receiver, which don't have built-in volume control) and be able to adjust the volume from anywhere in the room. If possible, it would be great for the unit to retain volume level while powered off.
If anyone could help me build such an equipment, I'd really appreciate it. I'm not an electronic graduate, so take it easy with me... any information will help: web pages, schematics, suggestions for circuits, anything. I live in Eastern Europe, can mail order most circuits and equivalents from a nearby components distributor. Thank you kindly for your time,
Best regards,
Mr. Titel
