Automatic A/B Line Level Switch
This switching device automatically selects between two line level sources to a single input. L/R RCA female input/output connections accommodate left and right channels, making it perfect for all consumer electronic devices.

Trigger sensitivity is fully adjustable from 10~100mV. Off delay (from B back to A after absence of signal) is adjustable in eight steps from 0.5 seconds to 10 minutes. The unit requires 12VDC, AC adaptor sold separately,
