[. . . ] The second input is unbalanced, and terminated to a single RCA connector. A contact closure will give priority to the balanced input. Activation of the balanced input priority turns on 18Vdc (300mA) power at a barrier connector on the rear panel, which may be used to drive LEDs or relays.

It shall operate on 115VAC or 230VAC at either 50Hz or 60Hz and have its source power supplied by a detachable IEC power cord. In addition, the unit shall be capable of being directly powered by a 24Vdc source such as storage batteries. It shall have a power switch on the front panel. The unit shall have a constant-impedance output to drive a 4 load at its rated output. It shall also have 25V, 50V, 70V and 100V constant-voltage outputs with like performance. The unit shall be capable of being remotely turned on from a stand-by mode, with a contact closure. The amplifier shall have an active balanced input and an unbalanced input. The balanced input connection shall be made through barrier connectors. The unbalanced input shall have a sensitivity switch on the rear panel to select between a nominal input signal of 0dB or ­20dB. This input shall be wired, in parallel, to an unbalanced output connector.
