Phantom Power
+48VDC 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 channel.
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.
Scene Memory
Direct Scene Memory recall switches (1–8)
Switchable Scene Memory recall (1–128)
