question

Can each output channel switch between either input? Aka can both channels play either source freely of one another or can Output 1 only play Input 1?
Asked by: Daniel L.
The JBL CSA 2120Z Audio Amplifier does not allow for source selection on each output. Input 1 will be routed to output 1 and input 2 will be routed to output 2.
