MUTE SWITCH
Pressing this switch will mute the signal sent to the main mix, aux sends, and FX effects.
The mute switch does not affect the signal sent to the solo system.
MUTE LED
The mute button is equipped with a red LED that lights up when the channel is muted.
PEAK LED
This LED usually indicates that the channel signal level is approaching clipping (distortion),
but it also lights up when muted. Because the peak indicator circuit monitors the signal
after gain, EQ and master level, peaks can be caused by high settings of any of these controls.
It lights up upon a static signal (test sound) of +15 dBu, which corresponds to the audible
peak of a highly dynamic signal (i.e. a piano). When lit, there is about 5dB of headroom
remaining, and the gain and EQ boost should be reduced. Under optimal settings of input
gain and EQ, LED will only flash briefly at the loudest peak.
PFL SWITCH
This PFL button allows monitoring of the signal on this channel through a speaker connected
to the CTRL ROOM OUTPUT or a headphone connected to the PHONES OUTPUT.
MAIN SWITCH
This button allows signals to be routed individually to the MAIN MIX.
GROUP 1-4 SWITCH
The BUS1/2, BUS3/4 buttons allow the signal to be routed to the stereo BUS 1/2, 3/4 respectively.
CHANNEL FADER
Used to adjust the signal level of the channel sent to the main output; control range is -∞ to +10dB,
the optimal position is 0dB.
LINE/Hi-Z SWITCH
To connect a guitar directly to the mixer without using a DI Box, press this switch down first; then connect the
guitar's output to the channel's 1/4" TRS input. This helps to match the directly connected input impedance
and preserve high frequency fidelity. The channel's 1/4" TRS input will become a line input, just like any other
mono line input. To use guitars or other instruments on other channels, you'll need to use an external DI box
first. Without the DI box or if this switch is not pressed the guitar may sound dull and muddy.

STEREO INPUTS (RCA)
RCA L/R line input which accepts signal from MP3 or CD player.
STEREO INPUTS
1/4'' TRS balanced or 1/4'' TS unbalanced line inputs. If you are
connecting a mono source, use the left (mono) input and the mono
signal will appear on both sides of the main mix.
STEREO GAIN
This control establishes the nominal operating level of the channel.
The input gain can be adjusted in a wide range (-20—+30dB). To maximize
the signal-to-noise ratio, the gain should be set to an appropriate level.
To do so, set the channel fader to 0, then press the PFL switch and
observe the LEVEL LED. If the CLIP LED glows and stays red, you need to
reduce the gain.
LINE IN / USB-B IN SWITCH
When this switch is not pressed, the input signal of this channel is provided by line input;
or when pressed, provided by USB-B.
