microphone transmitter. In addition to its use with wireless transmitters, the TR-50 can be
used as a low impedance hard-wired microphone with the TR-79 power supply. 12/48v
phantom powering (in addition to internal powering) is available on all TR-50*PS
microphones and TR-79+ positive bias power supplies.
The TR79 power supply provides a balanced transformer output to an XLR connector and
uses an Eveready 357 battery. The battery compartment is designed to permit only one
insertion direction, so the polarity cannot be reversed. This compartment is accessible by
turning the black plastic end cap counter clockwise and pulling firmly. The battery is removed
by pushing it out with a sharp object through the hole provided in the bottom of the
compartment.
