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 (1/4" 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 1/4" TS connector on the recorder/effects processor end, and a bridged stereo 1/4" TRS connector on the console end (tip and ring interconnected). {4} The TRIM 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. TRIM has a dual scale: the first scale has a gain from +10 to +60dB for the MIC input. The second scale has a gain from +10 to -40dBu for the line input. For devices with a nomal line output level of-10 dBV or +4 dBu the setting is as follows: with TRIM fully counterclockwise 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 TRIM, 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. Fig. 2.2: Equalizer section of input channels {6} 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). Control elements and connections 5 EURODESK SX3242FX/SX2442FX 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. Fig. 2.3: AUX/FX send controls in the channel strips {9} On each channel, the AUX 1 and AUX 2 controls allow you to determine the level of the aux signals sent from the channel. The main aux send signal comprising the aux send signals from all channels can then be adjusted with the corresponding master AUX SEND controls (51), and is present at the AUX SEND outputs (52). Both aux sends are mono, post-EQ, with a gain of up to +15 dB. (10) Press the PRE switch to set all aux sends to pre-fader. In this case, the volume of the aux signals is no longer dependent on the fader position, so you can create completely independent monitor mixes. + For most applications when controlling an external effects device from one of the aux buses, the aux sends must be set post-fader, so that the effect volume in a channel depends on the position of the channel fader. Otherwise, the effect signal would still be audible, even if the channel was turned down completely. For this type of application it is advisable to leave the PRE switch out (= not pressed). (11) FX 1 and FX 2 controls provide a direct route to the built-in effects processor. Additionally, they can be used to control an external effects unit, via the FX SEND 1 and 2 outputs (similar to the AUX SEND 1 and 2 jacks). To ensure that the internal effects processor and the FX SEND outputs actually get a signal, the corresponding FX control must not be set fully counter-clockwise (-oo), and the master FX SEND (see (60)) must be turned up. The FX buses are hard wired post-fader. + Please also read chapter 2.10 “Effects section” and 3 “Digital effects processor”. 2.1.4 Mono channel fader and further control elements Fig. 2.4: Channel fader, pan control, mute button, etc. (12) The PAN control determines the position of the channel signal in the stereo mix as well as the subgroup to which the channel signal is routed (see chapter 2.4).
