LOW CUT
The mono channels of the mixing consoles have a high-slope LOW CUT filter for 

eliminating unwanted low-frequency signal components (75 Hz, 18 dB/octave).

GAIN
Use the TRIM control to adjust the input gain. This control should always be 

turned fully counterclockwise whenever you connect or disconnect a signal 

source to one of the inputs.

COMPRESSOR
Each mono channel features a built-in compressor which lowers the dynamic 

range of the signal and increases its perceived loudness. The loud peaks are 

squashed down and the quiet sections are boosted.
Turn the COMP knob clockwise to add more compression effect. The adjacent LED 

with light when the effect is engaged.

2.1.2  Equalizer
All mono input channels include a 3-band equalizer. All bands provide boost or 

cut of up to 15 dB. In the central position, the equalizer is inactive.
The circuitry of the British EQs is based on the technology used in the best-known 

top-of-the-line consoles and providing a warm sound without any unwanted 

side effects. The result are extremely musical equalizers which, unlike simple 

equalizers, cause no side effects such as phase shifting or bandwidth limitation, 

even with extreme gain settings of ±15 dB.

The upper (HI) and the lower band (LO) are shelving filters that increase or 

decrease all frequencies above or below their cut-off frequency. The cut-off 

frequencies of the upper and lower band are 12 kHz and 80 Hz respectively. 

The mid band is configured as a peak filter with a center frequency of 2.5 kHz.

Fig. 2.3: The AUX SEND controls in the channel strips

Aux sends take signals via a control from one or more channels and sum these 

signals to a so-called bus. This bus signal is sent to an aux send connector and 

then routed, for example, to an active monitor speaker or an external effects 

device. The return from an external effect can then be brought back into the 

console via the aux return connectors.
For situations which require effects processing, the aux sends are usually 

switched post-fader so that the effects volume in a channel corresponds to 

the position of the channel fader. If this were not the case, the effects signal 

of the channel would remain audible even when the fader is turned to zero. 

When setting up a monitor mix, the aux sends are generally switched to 

pre-fader; i.e. they operate independently of the position of the channel fader.

Both aux sends are mono, are sourced after the equalizer and offer up to 

+15 dB gain.

AUX 1 (MON)
In the X1204USB, aux send 1 can be switched pre-fader and is thus particularly 

suitable for setting up monitor mixes. In the 1204USB, the first aux send is 

labeled MON and is permanently switched pre-fader.

PRE
When the PRE switch is pressed, aux send 1 is sourced pre-fader.

AUX 2 (FX)
The aux send labeled FX is for sending to effects devices and is thus set up to be 

post-fader.
In the X1204USB, the FX send is routed directly to the built-in effects processor.

PAN
The PAN control determines the position of the channel signal within the stereo 

image. This control features a constant-power characteristic, which means the 

signal is always maintained at a constant level, irrespective of position in the 

stereo panorama.

MUTE/ALT 3-4
You can use the MUTE/ALT 3-4 switch to divert the channel from the main mix 

bus to the Alt 3-4 bus. This mutes the channel from the main mix.

MUTE-LED
The MUTE LED indicates that the relevant channel is diverted to the submix 

(Alt 3-4 bus).
