Topping off the innovative design of the ERGOMIC, the microphone heads can also be easily switched between a Dynamic or Condenser element. The GA64/SC utilizes Galaxy Audio's popular mic elements from the HH64/HH64SC wireless mic transmitter. When the mic element is removed, this exposes a switch which must be moved when trading between condenser and dynamic elements. This switch is the on/off switch for the preamp when using phantom power to power the condenser element.
