(1). PEAK LED INDICATOR
This LED indicators lets you check the level of the signal input to the channel.
The peak indicator lights when the input signal reaches 5dB below the
channel’s clipping point. This indicator shows the level of the Post-EQ /
pre-fader signal. If the PEAK indicator lights more than briefly on high-level
transients, you should use the GAIN control to decrease the input sensitivity
of the channel. If this does not work, reduce the output level of the connected
source.

(2). GAIN CONTROL
According to the level of the input signal, use this knob to adjust the input to
an appropriate level. The best balance of S/N and dynamic range will be
achieved if you adjust the GAIN control so that the peak indicator lights
occasionally. This control adjusts the channel’s mic input sensitivity between

-50dB and -6dB and the line input sensitivity between -30dB and +14dB. The
mono/stereo combination input channels have a sensitivity of +20dB to

-20dB.

(3). HPF (High-Pass Filter, cut frequencies below 75Hz)
This switch toggles the HPF on or off. To turn the HPF on, press the switch in

).

(

(4). 3 BAND EQUALIZER CONTROLS
This is a 3-band equalizer with center frequencies, range and type as shown
below. The frequency response is flat when all knobs are in the “0” position.

(5). AUX CONTROLS
This knobs control the level of the signals sent to AUX bus.

(6).PRE/POST SWITCH
This button determines whether the AUX signal is Pre or Post fader. Pre
means not affected by the position of the channel fader. Post means is
affected by the position of the channel fader.

(7). EFX CONTROLS
This knobs control the level of the signals sent to EFX bus. The channel signals mixed by this bus have their overall level
set by the EFX SEND Control to the EFX SEND jack on the front panel. The EFX bus signal is also fed into the internal
digital signal processor. Since this control is placed after the channel fader, the signal level will be affected by the
channel fader setting.

(8). PAN/BAL CONTROL

PAN (Mono Channel)
This control pans the channel signal across the master L and R buses, thus determining the perceived position of the
sound from that channel in the output stereo sound field. If a PAN control is set all the way to the left, for example, the
sound from that channel will be heard from the left speaker system only. If it is set all the way to the right, the sound
will be heard from the right speaker system only. Intermediate settings will cause the sound to appear at corresponding
locations in the stereo sound field.

BALANCE (Stereo Channel)
This control adjusts the balance or the L/R position of the stereo input signal. Turning the BALANCE control to the left of
center moves the apparent source toward the MAIN MIX L moves the source toward the MAIN MIX R bus.

(9). MUTE/ALT 3/4 SWITCH
When the Mute/ALT 3/4 switch is depressed, a channel output will be routed to the ALT 3/4 output instead of the MAIN
L/R output. ALT 3/4 bus offers you a second independent stereo sub mix with its own sub master stereo fader.

(10). PFL SWITCH
When this switch is depressed, the channel input signal can be routed to the PFL bus. This switch allows you to monitor
the pre-fader channel input signal through headphone outputs and control room outputs.

(11). PFL INDICATOR
This indicator lights when the PFL switch is turned on.

(12). CHANNEL FADER
This is the channels main level control. It determines the level of the signal that is sent from the channel to the master
mixing and effect buses. It is the settings of the input channel faders that determine the mix, or the balance of sound
levels between the instruments or other sources connected to the inputs. When a channel is not being used, its volume
should be set at the minimum position to prevent the addition of unwanted noise to the main program signal.

above the VFX (EFX)ON/OFF switch to lookup the
desired effects.

(2). VFX PROGRAM SELECT SWITCH
This program knob selects one of the 100 built-in
digital effects, for each number you select. The VFX
programs feature a 24 Bit Digital Effects processor
with high quality, studio grade effects like Delay,
Chorus and Reverb.

(3). AUX PRE CONTROL
Adjust the level of the signal sent from the internal
digital effect to the AUX bus.

(4). VFX (EFX) ON/OFF SWITCH
This switch turns the internal digital effect on/off.

(5). PFL SWITCH
Set this switch on if you wish to output the effect
signal to the PFL bus.

(6). PFL INDICATOR
This indicator lights when the PFL switch is turned
on.

(7). EFX RTN Fader
Adjust the level of the signal sent from the internal
digital effect to the main bus.

(8). ALT 3/4 OUTPUT FADER
This fader adjusts the final level of the combined
stereo signal sent to the ALT 3/4 output jacks.

(9). MAIN L/R MASTER FADER
These faders adjust the final level of the combined
signals from all channels.

(10). TO MAIN L/R SWITCH
When this switch is on, the signal of each ALT 3/4 will
be sent to the MAIN L/R buses.

(11). Level-Meter Signal Switches (MAIN-ALT 3/4 Toggle Switch and TAPE IN Switch)

These level-meter switches, together with the channel PFL switches, select the signal that is sent through the CTRL
ROOM/HEADPHONE control to the CONTROL ROOM out jacks, the HEADPHONE jack, and the level meter. The following
illustration shows how the switch settings correspond to the signal selection.

(12). CTRL ROOM /PHONES CONTROL
Controls the level of the signal output to the HEADPHONE jack and CONTROL ROOM L and R jacks.

(13). TAPE IN CONTROL
This control adjusts the level of the playback signal that is inserted to the master mixing bus from the TAPE IN RCA
jacks on the top panel.

(14). MASTER SEND
* Master AUX Control
Adjust the level of the signal on the AUX bus to the corresponding AUX SEND jack.

* Master EFX Control
Adjust the level of the signal on the EFX bus. This is the signal that is output through the EFX SEND jack.

(15). PFL INDICATOR
This indicator lights when the PFL switch is turned on.

(16). OUTPUT LEVEL METER
A vertical row of ten LED shows the continuous output level of MAIN OUTPUT L/R. This type of display is highly visible

under poor lighting conditions. The 0 LED means an output level of +4dB for +4dB output (that’s the rated level).

(17). STEREO RETURN CONTROL
* AUX CONTROL
Adjust the level of the mixed L/R signal sent from the RETURN jack (L (MONO) and R) to the AUX bus.

* MAIN CONTROL
Adjust the level of the mixed L/R signal sent from the RETURN jack (L (MONO) and R) to the MAIN L/R bus.
