This Audiophonics RCA source selector lets you connect different analog sources to an amplifier, preamplifier or active loudspeakers. Its function is to enable permanent connection of multiple sources (up to 4) to a single amplification device. Once the source selector has been integrated into a complex audio installation, simply use the rotary knob to select the active source.

As a passive device, it can also be used in reverse, sending one source to several amplifiers, for example. The advantage of a source selector is that you can enjoy the convenience of changing sources without touching the connections of your Hi-Fi system. It also preserves the life of the system's mechanical parts (connectors, plugs, cables), as they are less subject to frequent handling.
