5 volt phantom voltage is available to power electret
microphones.
Technical Description
Microphone signals are passed to a voltage controlled
amplifier under control of a signal derived from rectifying
the stage output signals, providing 3:1 compression ratio.
The output of this stage is fed to an LED output level
display and a three-band equaliser (100 Hz, 1KHz, 10 kHz).
Power is supplied at nominal 24 VDC via separate cabling,
the phantom power on the audio + and audio - being used
for fault detection only. A regulator circuit provides 15 VDC
for powering the 1ZPR electronics.
The 1ZPR provides for the following LED indications
