DESCRIPTION

The 1593C Power Amplifier is a solid-state unit delivering 50 watts of power at less than 1% total harmonic distortion (THD) from 50 Hz to 12 kHz. The amplifier provides outputs for 4-ohm, 8-ohm and 16-ohm loudspeakers, plus a 70-volt line output for distribution systems. In addition to the high-impedance input, the amplifier has an octal socket to accept a line-isolation transformer. A selectable high pass filter is included for use in speech systems. Cut-off frequency of the filter is 300 Hz.
The 1593C is capable of operation from a 120V or 240V ac source or a negative grounded 28V dc source, and features silent, automatic transfer to dc operation if ac power fails.
Designed for rack mounting, the 1593C occupies three vertical units of rack space (5'/4"). A hinged front panel allows servicing without removing the amplifier from the rack.
