Input Features
Input Channels 15 & 16 Front Panel Features
MIC GAIN CONTROL Rotary control adjusts the gain of the microphone preamplifier. The range is +10
4.
to +56 dB. The output of this gain stage also drives the SIG/PFL LED.
GP 5/6 CH 9 SWITCH When this switch is in the default UP position, the microphone input feeds the
5.
main channel, and simultaneously the line inputs feed the Group 5/6 output buses. In the DOWN posi-
tion, the microphone input is disabled and both line inputs are summed and routed through the channel.
The Group 5/6 distribution is disabled in this mode. The LINE LEVEL control is attached to an active dual
gain stage just after the line input connectors and does not affect the microphone input gain.
EQUALIZATION Three-band equalizer with fixed shelving EQ at HF: 12.5 kHz, LF: 80 Hz and MF: 800
6.
Hz (bell shaped EQ). Adjustment from -15 to +15 dB with a center detent position is included.
AUX (PRE) SEND CONTROLS Aux 1 and Aux 2 are pre-fader foldbacks. Each control drives the corre-
7.
sponding Aux bus, after the Aux 1/2 gain stage, and has a range of infinity (OFF) to +10 dB. A center
detent is provided at 0 dB and represents unity gain at the Aux 1/2 amplifier stage.
AUX (POST) SEND CONTROLS Aux 3, 4, 5 & 6 are post-fader foldbacks. The two controls drive
8.
either the Aux 3/4 bus, or the Aux 5/6 bus, depending on the position of the AUX 3/4 AUX 5/6 push
switch. The default mode of AUX 3/4 is active when the switch is in the UP position. These post-fader
sends are driven from the main channel, post fader gain stage, just before the channel assignment stage.
Each control has a range of infinity (OFF) to +10 dB. A center detent is provided at 0 dB and represents
unity gain at the post fader stage (AUX 3 - 6 outputs).
BALANCE CONTROL A single rotary control assigns the post fader audio, after the final channel gain
9.
stages, to any combination of the Odd (Left, Group 1, Group 3) or Even (Right, Group 2, Group 4) side of
the main output buses. Which buses are driven is determined by the position of the L/R, 1/2 and 3/4 Bus
Assign switches.
MUTE SWITCH This push button switch toggles the channel audio mute status. When the switch is in
10.
the DOWN position all audio is muted, including the L/R, Group 1-4 and Aux 1-6 bus sends. The
MUTE/PK LED will illuminate RED when the channel is muted.
MUTE/PK LED This dual-function LED will illuminate solid RED when the channel is muted. When the
11.
channel is not muted, this LED will flash to indicate audio clipping. Clipping indication is provided after
the first gain stage and the EQ (pre-fader). The LED becomes active at 2 dB below the clipping point at the
output bus.
SIG/PFL SWITCH This push button switch toggles the channel audio onto, and off of the PFL head-
12.
phone bus. When the switch is in the DOWN position, the audio is included in the PFL mix, and the PFL
(right master) meter (see page 28). The corresponding SIG/PFL LED will illuminate yellow when active.
SIG/PFL LED This dual-function LED indicates the status of the PFL assign and the audio signal level.
13.
When the LED is illuminated with solid yellow, the channel is assigned to the PFL bus, as determined by
the SIG/PFL switch. When the channel is not assigned to the PFL bus, this LED will constantly indicate
the audio signal presence level (-15 dBu) after the EQ, and just before the fader.
BUS ASSIGN SWITCHES (L/R, 1/2, 3/4) Three switches for assigning the post-fader audio to any com-
14.
bination of the Left/Right, Group 1/2 or Group 3/4 output buses. The assignments are made in pairs when
the switch is in the DOWN position. When none of the assign switches are in the DOWN position, the
channel audio signals will not appear at the main output buses.
FADER 60 mm precision fader controls the channel's main audio after the final gain stage and before the
15.
assign switches. Unity gain is represented by the 0 dB mark and the range is infinity (OFF) to +10 dB.
