Description
| This audio selector for BF (audio-frequency) signals makes it easy to choose between four stereo sources and route the signal to two separate outputs: a fixed one for recording and an adjustable one for amplification, fitted with volume control. Thanks to digital channel selection, it offers stable, precise and reliable audio signal management.
The inputs can be selected via jumper, but for even more convenient operation you can use an external 4-channel selector (available separately), which lets you switch sources without working directly on the circuit. A fifth, additional input, called Tape Monitor, is also available, selectable via toggle switch, ideal for directly connecting cassette recorders, reel-to-reel decks or other devices with a monitoring function. Perfect for anyone wanting a simple, effective solution without resorting to complex or costly systems, this device lets you manage multiple audio sources while always keeping volume control on the output feeding the amplifier. Note: the potentiometer knob is not included and can be purchased separately. Soldering required for assembly. The kit is supplied complete with instructions. ![]() |
