The key to more rig possibilities.
The Diamond Amplification MAC-2 lets you control your amp from your MIDI controller. The MAC-2 is designed to control any 1/4" tip to ground switching mechanism. Simply connect your cable from a function jack on the MAC-2 to your control jack, set the state of the switch, send a MIDI patch change to the MAC-2 and hit write. Every time you select that MIDI preset on your MIDI foot controller, that switch returns to its memorized state.
The MAC-2 provides you four jacks, three 1/4" mono jacks and one 1/4" TRS jack for a total of five functions, which means the MAC-2 can control up to five functions like effects functions activated through 1/4" jacks, amp channel switching or features. Control two amps, one amp and multiple effects pieces, etc.
