Phantom Power +48 VDC is applied to balanced inputs (via
6.8 kΩ current-limiting/isolation resistors) for
powering condenser microphones; may be
turned ON or OFF via rear-panel phantom
Master switch.
When Master is ON, individual channels
may be turned ON or OFF via +48V
switches (with red LED) on each input chan-
nel.
CH LED Indicators
PEAK LED(red) built into each CH INPUT turns on
when pre-Fader level reaches +17 dB.
NOM LED(yellow) built into each CH INPUT turns
on when pre-Fader level reaches 0 dB.
SIGNAL LED(green) built into each CH INPUT turns
on when pre-Fader level reaches –13 dB.
ST CH LED Indicators
PEAK LED(red) built into each ST CH INPUT turns
on when pre-Fader [L+R] level reaches
+17 dB.
NOM LED(yellow) built into each ST CH INPUT
turns on when pre-Fader [L+R] level
reaches 0 dB.
SIGNAL LED(green) built into each ST CH INPUT
turns on when pre-Fader [L+R] level
reaches –13 dB.
Oscillator/Noise Switchable sine wave @ 100 Hz, 1 kHz or
10 kHz, or pink noise.
