  • Master Control Unit

    A versatile "master control" pre-amplifier unit for microphone, recorded, or radio inputs.

    Provides compensation for four recording characteristics together with comprehensive tone control. In addition to standard equalization for the principal recording characteristics, it has independent bass and treble controls giving continuously variable rise and fall up to 30 dB, and separate variable-slope filters giving a "roll-off" at alternative fixed starting frequencies of 5, 7, and 9 kHz.

    An interesting feature is the ingenious parallel-line graduation of the front panel which serves all the controls.

    Supply requirements: 8 mA at 350 V, 2 A at 6.3 V.

    Finish: Panel & knobs cream, chassis Lowther green ripple.
