Scope of application:
1. Switch between signal sources such as CD players, digital broadcasting, set-top boxes, radios, decoders, etc. and power amplifiers (or active speakers);
2. Switch between the front and rear stages of the power amplifier.
A switcher, as the name implies, is a switch. It cannot mix multiple input signals, nor can it output multiple channels at the same time. The signals can only be rotated in and out.
