Tram Power Supply. For microphones with a TA5F for Lectrosonics systems. Positive bias. Runs on a standard watch battery.
The TR79 power supply provides a balanced transformer output to an XLR connector and uses an Eveready 367 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.
Remove the internal battery when using phantom power. The battery should be removed when the microphone is not used for extended periods of time.
