AMP 1
If you are using the interface to control a single amp, plug it in here. The amplifier
supplies power to the interface through this connector, so an additional power supply is
not required.
Use a cable with 8 pin male DIN connectors on each end. You should have received a
cable with your unit. Be careful with this cable. It IS NOT commonly available in most
music or electronic stores.
If it ever becomes necessary to replace it, you can order one from Rivera or make it
yourself. It does not require shielded cable, and the pins are wired straight through.
(1-1, 2-2 etc.)
AMP 2
The FS7M has two amplifier connectors. The second connector can be used to control
a second amplifier if grounding issues are addressed. If you connect the audio path of
two amplifiers together and also connect the footswitch control path, a ground loop will
be created. This ground loop may produce a bad hum.
There are many different techniques to eliminate this problem. Solving ground loop
problems can sometimes be tricky depending on the details of your setup. This manual
does not provide instructions for fixing ground loops. If you have a question about a
specific combination of amps, please contact the factory, we will try to help.
MIDI IN
Standard MIDI input. Use this to connect any standard MIDI controller.
MIDI THRU
Standard MIDI thru, passes data from the MIDI IN to additional MIDI gear.
