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.

6.1 - Microphone inputs
The microphone inputs are accessible via XLR chassis and can receive both balanced and unbalanced low-level signals
Both low-impedance condenser and dynamic microphones can be connected (channels 1 to 4).
CAUTION: Connecting unbalanced sources while the phantom power supply is activated will cause
severe damages to your devices due to the voltage delivered via pins 2 and 3.

Mono line-level inputs are accessible via Jack or RCA chassis and can receive both balanced and unbalanced signals.
These inputs can be connected to CD players, MP3 players, Tuners or cassette players.
When connecting unbalanced sources, you will be required to connect the ring to the body.
You can also use the RCA inputs to connect CD or MP3 players, etc.
CAUTION: Turn the volume of affected channels at their minimum before connecting line-level signals
to prevent serious damages to your amplification system.
