Randall Amplifiers RF8 - Manual

Randall RF8 User’s Manual
The Randall RF8 MIDI footswitch is an 8 button MIDI controller that can work with a variety of amplifiers and
other MIDI devices. The RF8 can be configured to send MIDI program change messages, continuous
controller messages or both.
Connecting to your amp or other MIDI device:
The RF8 has a 7-pin MIDI connector, but you can use either a standard 5-pin or 7-pin MIDI cable to connect
to your MIDI device, whichever matches the connector on the device. Either type of cable will work with the
RF8.
Powering the RF8:
If your MIDI device provides phantom power over pins 1 and 3 or pins 6 and 7 of the MIDI connection, it will
power the RF8. If your MIDI device doesn’t provide phantom power, you can power the RF8 with an AC
adapter. The RF8 accepts 9 to 12 volts, AC or DC and draws 100mA.

Settings:
The RF8 can work in a variety of different modes. The RF8’s mode determines how many of the RF8’s
buttons send program change messages and how many send continuous controller messages.
There are four switches on the rear of the RF8 that control the mode. Moving a switch up turns it on and
moving it down turns it off. The different switch combinations – and the MIDI messages they send – are as
follows:
