SoundDigital SW8 8-Way Automatic/Manual 2-in-1 Switch

The SW-8 is a high-performance 8-channel audio A/B switcher with automatic/manual switching capabilities. It enables one-touch switching of output signals from Group A's 8-channel balanced audio input to Group B's 8-channel input. The internal circuitry features passive/lossless switching with active control architecture. Manual mode supports both digital and analog signals, while power-off A-channel bypass and dual power supply ensure reliability. Multiple SW-8 units can be connected for seamless one-touch switching, maximizing operational safety. This device is ideal for audio systems in studios, main control rooms, and broadcast vans.

Two switching modes

·Automatic switching mode: Selects either an external signal (analog audio) or the first channel of Group A as the detection source (digital/analog compatible, following the input signal pattern). When the input signal falls below a specified threshold for an extended duration, the switch automatically switches channel A to channel B (8 channels switch simultaneously).

·Manual mode: (Digital/analog compatible) When the device is set to manual mode, the A/B signal channels (8 channels each) can be switched with a single button.
