ARCHITECT'S AND ENGINEER'S SPECIFICATIONS
The power amplifier shall be capable of operating
from a 100/120/220/240V ac line or from a
24/28V dc battery. The power supply shall auto­
matically transfer the power to dc operation if ac
power fails. An octal socket shall be provided on
the rear panel for installation of an accessory line
transformer. The front panel shall be hinged to
permit access to the chassis interior without
removing the amplifier from the equipment rack.
The power amplifier shall meet the following per­
formance criteria. Gain, 61 dB. Input sensitivity,
0.8V rms for rated output. Power output, 50 watts
at less than 1% THD from 50 Hz to 12 kHz. Fre­
quency response at 1 watt output, ± t dB from 20
Hz to 20 kHz and ± 1 dB 50 Hz to 12 kHz at rated
