RJM Carol-Ann MIDI Interface Instruction Manual

Carol-Ann MIDI Interface
Instruction Manual
This interface is designed to connect a Carol-Ann amplifier to any MIDI controller,
allowing the amp to be switched in conjunction with any other MIDI capable equipment
you may have. This interface is compatible with any Carol-Ann amp that originally
came with a 4 button or 5 button footswitch. It isn't compatible with any other amp.

Basic Operation

Using this MIDI interface is pretty simple: connect this interface to your Carol-Ann amp
using the amp's footswitch cable. Then, connect the MIDI output or MIDI thru
connector of your MIDI device to the MIDI input on the interface.
Once connected, the LED on the front panel should light up red to indicate it's powered
up. Any MIDI program change (PC) message sent to the interface on MIDI channel 1
will change the amp's channel, lead boost and effect loop (on models that have a
switchable effect loop).
The PC number determines which channel and other features are turned on:
PC#0: CH1, loop on, lead boost off
PC#1: CH2, loop on, lead boost off
PC#2: CH3, loop on, lead boost off
PC#3: CH2, loop on, lead boost on
PC#4: CH3, loop on, lead boost on
PC#5: CH1, loop off, lead boost off
PC#6: CH2, loop off, lead boost off
PC#7: CH3, loop off, lead boost off
PC#8: CH2, loop off, lead boost on
PC#9: CH3, loop off, lead boost on
The PC number sequence repeats: PC10 is the same as PC0, PC11 is the same as
PC1, etc.
