AUX 1-2 MASTERS

These controls set the levels of the AUX 1-2 channels sent to the output connectors. It ranges
from (–)infinity, to unity gain at the center detent position (reference setting), to +6 dB at full 
clockwise. 

53. GROUP 5/6 

ASSIGNMENT 

SWITCHES

These switches connect the Group 5/6 signal to MASTER L/R, GROUP 1/2 and GROUP 3/4 
buses.

GROUP 5/6 TO AUX 1 and AUX 2 CONTROLS

These two rotary controls set the level of the GROUP
5/6 signal sent to AUX 1 and AUX 2. Adjustments 
range from (–)infinity, to unity gain at the center 
detent position (reference setting), to +10 dB at the

55. HEADPHONE 

OUTPUT

This stereo (TRS) jack, located on the front panel, 
provides the signal to drive stereo headphones. 
Tip=Left, Ring=Right, Shield=Ground. The level at 
the Headphones and Control room outputs is set by 
the headphone level control (56). These two outputs 
listen to L/R Master output (default) or choice of 
2TRK input or AUX 1 - 2 signals according to the 
position of the corresponding L/R–AUX 1 - 2 –2TRK 
switches in the headphone master section. When 
one of the PFL switches on any channel or 
Group is engaged, these outputs listen to the PFL
(mono signal in both headphones).

LEVEL CONTROL

This control adjusts the level of the stereo 
Headphone and Control room outputs.

L/R-AUX 1 - 2 -2TRK SELECTORS

AUX 1 - 2 or 2TRK input) is to be monitored on the headphone and CR outputs, when none of the
PFL switches on neither Channel nor Group is engaged.

58. PFL ACTIVE

This yellow, master PFL LED blinks when the PFL is active and its signal is overriding 
the default L/R mix in the headphone and CR outputs and at the L-R meters. The signals that
are present in the PFL mix can be identified by the individual LEDs lit near the corresponding 
Channel or Group PFL switch.

59. 

PHANTOM POWER CHANNEL 1—2, CHANNEL 3—16

These two switches apply the +48V DC phantom power to the mic inputs of Channels 1-2 or 
Channels 3-16 separately. Engaging Channels 1-2 switch on the master section a48V
DC to the microphone XLR connectors of Channels 1 and 2 to power condenser microphones
that require it. Respectively, engaging Channels 3-16 switch a48V DC voltage to the 
microphone XLR connectors of Channels 3 through 16.
