Input equalization
Each channel features a 3-way signal equalization.
These knobs allow you to increase or decrease basses
(LOW), mid frequencies (MID) and trebles (HIGH) of each
outgoing signal.
Microphone channels only feature these settings.
- HIGH (High Frequency control): Allows you to adjust
trebles of the corresponding channel from -15 to +15 dB
at 12.5kHz. Turn this knob clockwise to increase trebles,
while turning it counterclockwise decreases them.
The middle position does not modify trebles.
- MID (Mid frequency control): Allows you to adjust mid
frequencies of the corresponding channel from -15
to
+15 dB at 2.5kHz. Turn this knob clockwise to increase
trebles, while turning it counterclockwise decreases
them.
The middle position does not modify mid frequencies.
- LOW (low frequency control): Allows you to adjust
basses of the corresponding channel from -15 to +15 dB
at 2.5kHz. Turn this knob clockwise to increase trebles,
while turning it counterclockwise decreases them.
The middle position does not modify basses.

Signal indicators
Indicate an incoming signal on the corresponding input.
3
CLIP Indicators
Alert when detecting any signal with excessive volumes.
It is strongly recommended never exceed a few clip
alerts in order to preserve your equipment.
4
LEVEL input knobs
Allow you to adjust input levels.
They have a range of 44dB, from -50 dB to -6 dB for
microphones and -30 dB to +14 dB for line levels.
5
1, 2, 3 and 4 buttons
Allow you to assign each way to an output (OUTPUT1,
OUTPUT2, OUTPUT3 ou OUTPUT4) or to all 4 zones at
the same time.

Output equalization
- HIGH (High Frequency control): Allows you to adjust
the output signal trebles from -15 to +15 dB at 12kHz.
Turn this knob clockwise to increase trebles, while
turning it counterclockwise decreases them.
The middle position does not modify trebles.
- LOW (low frequency control): Allows you to adjust the
output signal basses from -15 to +15 dB at 12kHz.
Turn this knob clockwise to increase trebles, while
turning it counterclockwise decreases them.
The middle position does not modify basses.
7
Output LED indicators
Allow you to visualise the output sound level for each
zone.
8
CLIP indicators
Indicate an excessive signal level on the corresponding
channel.
We strongly recommend not to exceed brief flashes of
these LEDs in order to prevent sound distortions.
9
MUTE buttons
Allow you to mute all zones or only selected zones.
10
1, 2, 3 and 4 switches
Allow you to monitor OUTPUT 1, OUTPUT 2, OUTPUT 3
and OUTPUT 4, either one at a time or altogether.
11
PFL / AFL switch
Allow you to send the pre-fade signal (before channels
alterations) to the monitoring area.
PFL : You are monitoring outgoing signals.
AFL : You are monitoring incoming signals.
12
Monitoring speaker
Allows you to monitor selected inputs or outputs.
