G-Lab's MAC-4.4 MIDI Amp Controller is an adapter that enables you to control amplifiers equipped with External Switching or Footswitch inputs. The MAC-4.4 can be controlled with every programmable MIDI controller (which enables to program and send chosen MIDI program change or control change commands for any controller's preset). The control signals are applied to a terminal strip that can connect up to eight mono jack cables (like the SC-MB cable set) to be connected to the corresponding jacks on the amplifier.
The MIDI Amp Controller can either be supplied from the 9V power supply adapter or from the GSC-2 controller - through the MIDI cable (five wire) by using the MIDI PHANTOM adapter. The MAC-4.4 MIDI Amp Controller can be placed in a rack system using the G-Lab 1U RMS Front Panel.
