MIDI CHANNEL SELECTING

The channel switching function of the RT2-50 can be used with any MIDI capable guitar preamp.   The RT2-50 was

designed to compliment the RM4 modular preamp, but will also give you tube power for all the current MIDI digital

guitar preamps.    

PROGRAM CHANNEL SWITCHING

1. First connect a 5-pin MIDI cable from the  THRU  jack on RM4 or other MIDI guitar preamp, to the  IN  jack on

the rear panel of the RT2-50.  

2. First select the module or channel from your preamp that you will be assigning to the certain power tubes.  

3. Once you have the selected the preamp channel, select which RT2-50 channel you want to program to this

particular preamp    channel.     

4.  After you have selected the preamp channel and RT2-50 channel you want to use, simply press and hold the

RT2-50 channel select button for 3 seconds, and it is now programmed for that preamp channel.  

5. Repeat this process to program any of your modules or preamp channels, to be used with the desired power

tubes.   

6. Once you have programmed all the your modules or preamp channels, to the specific power tubes, you can now

use the RF4 or MIDI footswitch to select both the preamp and power tubes at the same time.
