The RS-10 requires 9VAC at approximately 200ma. Power is applied via pins 6 and 7 of the 7 pin MIDI out port. If your
RS-10 is equipped with a 5 pin MIDI Out jack, power will be applied to pins 1 and 3. There is no provision for power input
other than these connections. When using the RS-10 with other CAE products, such as the 4x4 or 2x4 Audio Controller,
use a 7 pin cable to connect the RS-10 MIDI out to the CAE rack unit’s MIDI in. An adapter may be required if the RS-10
is supplied with a 5 pin MIDI out connector. There is no need for an extra 9VAC adapter. The 9VAC that powers the rack
unit also supplies power to the RS-10. RS-10’s supplied with custom switching systems from CAE may also have XLR
connections for power and MIDI out. These are usually 4, 5 or 7 pin configurations. Consult the factory if there are
questions regarding phantom powering of other units.
