Pro Panel Internal/External Switch with Output and Input Jacks Above

Switch to Internal puts signal direct from 8ohm output to internal speaker (8ohm). Switch to External sends signal to OUT to either External Cabinet or device such as Night Light's FROM AMP jack (switchable on fly). You would then connect the TO SPEAKER cable from Night Light to the IN jack above, this routing the NL's signal BACK to the internal speaker. NOTE: ALWAYS HAVE A LOAD CONNECTED TO THE OUTPUT JACK WHEN SWITCHED TO EXTERNAL. Ideal match should be 8ohms. If no load present for extended period with switch to EXTERNAL, damage can occur to Output Transformer. NL does count for a load if connected though the TO SPEAKER back to INPUT on panel must be connected if the NL is ever in BYPASS mode. In addition, you can only run EITHER the internal speaker OR the External Cabinet, not both at same time. For more on NL including hookup diagram, see Night Light FAQ.
