The ARMD allows you to control the footswitch functions of Tech 21s Trademark Series of guitar amplifiers and Landmark Series of bass guitar amplifiers with any MIDI controller. Connect a standard MIDI cable from the MIDI out on your MIDI controller to the MIDI In of the ARMD. Connect any standard instrument cable from the 1/4 Out of the ARMD to the 1/4 footswitch jack on whichever amplifier you want to control. An additional 1/4 Out is provided for connecting two of the same amplifiers. The ARMD is phantom powered through the instrument cable from the footswitch jack on the amplifiers, so batteries are not required. A MIDI foot controller transmits information to remotely control anything that accepts MIDI program change information. In order to communicate program change information, the MIDI controller and the ARMD must be set to the same channel. Channels can be set on the ARMD by accessing the internal DIP switches. The factory setting for the ARMD will be for Channel 1 and the AR6 footswitch. If you are using the Trademark 60, Landmark 300 or 600 model amplifiers, set the #6 DIP switch to the up position for the AR3 footswitch.
