120 VAC 50/60 HZ 15 VA: Power Cord. Connect to a properly grounded AC source.

12 VAC: These two terminals provide 12 volts of ac current. These are available for connection to low power accessory units.

INPUT: These three terminals, labeled + for the positive or “hot” connection, - for the negative connection, and the ground symbol for earth ground connection are for connection to the balanced or unbalanced input signal to be distributed.

CH6 - CH1: For each channel; the two terminals labeled + for the positive or “hot” portion of the output signal, and the - for negative or neutral portion. The ground signal indicates the terminal to be connected to earth ground. This terminal may be lifted in the event of ground loops.

INSTALLATION

Install the RA63 in a standard 19” rack. The unit is intended for installations where several zones or areas need to be controlled and a high level balanced signal is required to drive the input lines.
