Power Supply for TR50 with Lectrosonics TB5M Connector


Detachable power supply with Lectrosonics TB5M connector. 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. Negative bias, operates on internal battery only.
