EURODESK SX3242FX/SX2442FX User Manual

This chapter describes the various control elements of your mixing console. 

All controls and connections are explained in full detail.

Connectors and controls of the mic/line inputs

(1) 

Each mono input channel is equipped with a balanced microphone input 

on an XLR connector, which provides +48 V phantom power for condenser 

microphones at the touch of a button (see rear panel).

(2) 

Each mono input also has a balanced line input on ¼" TRS connectors.  

Of course, these inputs can also be used with unbalanced plugs  

(¼" TS connector).

(3) 

The INSERT I/O connector is used to process a signal with dynamic 

processors or equalizers. This insert point isprefader, pre-EQ and 

pre-aux send.

 

 Unlike reverb and other effects, which are usually added to the dry signal, 

dynamic processors process the entire signal. So, aux send buses are not the 

best solution here. Instead, dynamic processors and equalizers are inserted 

into the signal path. Once processed, the signal then re-enters the mixing 

console at the same point where it left. Signal interruption only occurs if 

a plug is inserted into the corresponding jack (¼" stereo plug: tip = signal 

output, ring = input). All mono input channels are equipped with insert 

points. They can also be used as pre-EQ direct outputs, without signal 

flow interruption. For this you need a cable with a ¼" TS connector on the 

recorder/effects processor end, and a bridged stereo ¼" TRS connector on 

the console end (tip and ring interconnected).

(4) 

The GAIN control adjusts the input gain. Be sure to set this control fully 

counter-clockwise before you connect or disconnect a signal source to or 

from one of the inputs.

  

GAIN has a dual scale: the first scale has a gain from +10 to +60 dB for 

the MIC input.

 

 The second scale has a gain from +10 to -40 dBu for the line input. 

For devices with a nomal line output level of-10 dBV or +4 dBu the setting 

is as follows: with GAIN fully counter-clockwise connect the external device 

and adjust the output level recommended by the manufacturer. If available, 

the output level display of the external device should read 0 dB with signal 

peaks. For +4 dBu increase GAIN, for -10 dBV increase it further. The fine-

tuning can be done with a music signal and the LEVEL SET LED, which will 

illuminate when the optimum operating level has been set.

(5) 

Mono channels are equipped with a high-slope LOW CUT filter eliminating 

unwanted low-frequency signals, such as floor rumble (18 dB/oct., -3 dB  

at 80 Hz).

2.1.2  Equalizer
All mono input channels are equipped with a 3-band equalizer. The maximum 

boost/cut of the individual bands is 15 dB, in mid position the EQ is set to neutral.

The HIGH control in the EQ section controls the high frequency range of 

the respective channel. It is a shelving-type filter which can boost or cut all 

frequencies above a fixed frequency (12 kHz).

(7) 

The MID control allows you to raise or lower the mid-range level. It is a semi-

parametric peak filter, which boosts or cuts the frequency range around a 

variable mid-range frequency. Use the FREQ control to select the mid-range 

frequency from 100 Hz to 8 kHz. Then use the MID control to boost or cut the 

selected frequency range.

(8) 

The LOW control boosts or cuts the low-frequency range. Like the HIGH filter 

it is a shelving-type filter, which raises or lowers the level of all frequencies 

below a specific frequency (80 Hz).

2.1.3  Aux/FX send buses
Aux sends enable you to take the signals from one or multiple channels and 

collect them on one bus. This signal is then present at one of the aux send jacks, 

from where it can be routed to an active monitor speaker or external effects 

device, for example. The FX returns are subsequently used as a return bus for the 

processed signal.
