Fig. 1 - M5700 Transistor Program Amplifier
The Gates Transistor Program Amplifier is
available in two versions:
1. The M5700 is designed specifically for
use in Gates Transistor Consoles. It is
supplied less the interstage level control.
and with th,e input unterminated. The con-
trol is mounted externally on the Console
panel.
2. The M5700B is designed for rack mount-
ing in system installations with the level
control mounted internally.
The input of
the amplifier is unterminated to facilitate
application.
Terminate the input connect-
ions on the amplifier mounting tray in the
proper resistance (150 or 600 ohms).
The
gain of the M5700B will then be approxi-
mately 70 db maximum.
