phantom power—+48V
48 volts DC is applied to pins 2 and 3 on the mic-input XLR connector. This option is used with condenser microphones and active dir ect
boxes that require an external DC voltage (phantom power) in order to
operate.
pad
The mic-input signal is attenuated by 20dB to prevent some signals
(e.g.kick drum or lead vocal) from overloading the preamp stage.The pad
is used to bring a hot mic-input signal down to a controllable level. The
20dB pad is not functional when the
LINE switch is depressed.
line
The input preamp circuit is set up to accept a mic-level signal. This
signal is brought in via the XLR mic-input connector located on the rear
panel.The 1/4" TRS input jack is disabled.
The input preamp circuit is set up to accept a line-level signal from
either the XLR mic-input connector or the 1/4" TRS input jack,both located on the rear panel.
When a plug is inserted into the 1/4" TRS input jack, the XLR mic-input
connector is disabled.
polarity reverse—ø
This feature is used for correcting or minimizing polarity and phase related errors. For example, occasionally a balanced input connection is
reverse-wired before it gets to the mixing console. This can happen in
microphones,or in snake line interfaces.By using the polarity reverse feature,this type of error can be corrected.
polarity inverted
polarity not inverted
If the channel peak
LED is illuminated,
first try lowering
the input gain control.
Only when this method is
unsuccessful should the pad
switch be engaged.
+
If the 48V phantom
power switch is
engaged, depressing this
switch disconnects phantom
power from the mic input
XLR.
+
1
When similar signals
from different channels are combined, phase
cancellations can occur.
Reversing the polarity of an
input signal often corrects
such phasing errors.
+
The 48V switch should
not be engaged when
using standard (dynamic)
microphones, or other
sources that do not use
phantom power.

gain
The Input gain control range is closely related to the status of the
PAD
switch and the
LINE switch. In order to establish proper gain structure in
the console,input gain settings must be set correctly.
LINE—switch-up PAD—switch-up
15 to 75dB of gain can be added the mic-input signal.
The impedance at the input XLR is 4kΩ.
LINE—switch-up PAD—switch-down
-5 to 55dB of gain can be added to the mic-input signal.
The impedance at the input XLR is 4kΩ.
LINE—switch-down PAD—switch-up or -down
-10 to 45dB of gain can be added the line-input signal.
The impedance at the input XLR and input 1/4" TRS is 20kΩ.
high-pass filter—HPF
Proper use of the high-pass filter reduces or eliminates unwanted low fr equencies without substantially affecting the program material.Quite often
such unwanted low frequencies are included with in-coming mic- or lineinput signals.For example,stage rumble or wind can be picked up through
vocal mics.The slope of the high-pass filter is 12dB per octave.
HPF
High-pass filter is on.
HPF—variable control
When the high-pass filter is on, this control selects a frequency
between 20Hz and 400Hz as the point where attenuation begins.

bus assignment features
The Input bus assignment section offers considerable flexibility for creating what eventually becomes the main output mix.Such features as
LCR,
GROUP PAN ON
and eight-individual group assignments allow several
approaches to building the desired mix.All assignments are derived postfader, post-eq,and post-mute.
left-center -right—LCR
This feature is used to precisely position a signal in a sound system with a
center speaker cluster in addition to left and right clusters.The
PAN control
becomes an integral part of how the input-signal is sent to the
LEFT,CEN-
TER,and RIGHT outputs.
The post-fader signal is assigned to the
LEFT,RIGHT
,and MONO/
CENTER
buses.Relative amounts of the signal fed to each bus is determined by the
position of the
PAN contr ol.
pan control
The pan control positions the signal within the stereo left/right field,
(or between left/center or center/right in
LCR mode).The signal must be
assigned to either LCR or the L-R bus for the pan control to have any
affect.
see—left-center -right
safe preview—LED
Green steady
This means that the mute function is in safe-mode.If the channel is part
of a mute scene,it will not be activated when the scene is recalled.The
local mute function operates normally regardless of whether or not the
channel is in safe-mode.
Green flashing
The micro mute system is in edit-safe mode,and the channel is included
in the safe-scene.Pressing the local mute button will include or exclude
the mute from the safe-scene.
Pressing the edit-safe button in the micro channel section will r emov e the
console from edit-safe setup mode and save any changes that have been
made to the safe-scene. At this point, the green-
LED will stop flashing.
The green-
LED will light steadily if the channel is part of the safe-scene, or
extinguish if it is not part of the safe-scene.

When in safe-mode,
a channel will not
accept commands for any
external source.
Commands sent from the
master onboard processor
and any external MIDI
device will also be ignored.

mute
The Mute switch has three functions:
1 It acts primarily as a local mute switch by activating and deactivating the
mute. When any mute is activated locally,it will remain muted until it is
deactivated locally regardless of whether or not the mute is part of the
safe-set or an active mute scene (or a mute scene that has been made inactive).
2 It is used in creating and editing mute scenes when the micro-
processor mute section is in edit-preview mode.
3 It is used for including and excluding the mute in the safe-set when the
microprocessor mute section is in edit-safe mode.
This switch is illuminated whenever the channel is muted.

peak indicator—PK
The input signal is monitored at several points throughout the channel. These points are the mic preamp, the EQ stage and the fader stage.
Overloads at any of these stages will cause the red peak-
LED to light.
Then the channel gain should reduced.
signal level LED’s
These three LED's light up at +8—yellow, 0—green, and -6 dB—
green. This level range -6 to +8 is the optimum operating range.
Compressed or relatively constant signals should remain close to 0.
signal present indicator—SIG
This green-LED varies in brightness in response to signal levels
between -40 dB and -6 dB.
Occasional flashing of the
peak LED is acceptable,
but frequent flashes indicate that channel levels
must be lowered.

This switch must be activated for the TALKBACK system to operate.
There are two-ways to activate it:
1 Momentary - Depressing the button for more-than 1/2 of a second will
cause it to act as a momentary switch.When the button is released, the
T ALKBACK section will be shut-off.
2 On / Off - A quick tap on the button (less-than 1/2 second) will cause
the switch to electronically change its state fr om on-to-off or from off-to-on.
left/right/center—LCRTO OUTPUTS
This feature is useful for monitoring the console when creating an LCR
mix.Local monitoring is usually done with two speakers.The
LCR to out-
puts feature combines the center (or mono) signal with the left and right
signals,creating a phantom center channel.This feature affects the
AL T OUT
section,the
MONITOR OUT
section,the HEARING ASSIST output and the head-
phone feed.
Center (mono) channel is not included in the
MONITOR
paths.
The center (or mono) channel is combined with left and right
MON-
