EURODESK SX3242FX/SX2442FX

(20)All stereo channel strips have a TRIM control for gain adjust- ment. Its scale ranges from +20 to -20 dB and allows you to adapt the input level to the line inputs.

2.2.2Stereo channel equalizer

Fig. 2.6: Stereo channel equalizer

The stereo channels are equipped with a stereo equalizer. The filter types and cutoff frequencies for HIGH and LOW filters are the same as on the mono channels. Instead of one semi-paramtric midrange band, the stereo channels have two separate midrange bands ((21) HIGH MID and LOW MID) with fixed mid-frequencies (3 kHz and 400 Hz). Stereo EQs are preferable for processing the frequency response of stereo signals. With two mono equalizers you might encounter problems with different settings between the left and right channels.

2.2.3Stereo channel aux/FX send buses

Basically, the aux and FX buses on the stereo channels are the same as on the mono channels. Since aux buses are always mono, the signal from a stereo channel is first mixed to mono before it is routed to the aux bus.

2.2.4Stereo channel fader and other control elements

(22)The BAL(ANCE) control has the same function as the PAN control on the mono channels. It determines the relative volume of the left and right input signals before they are routed to the stereo main mix bus (or to two subgroups).

All other control elements of the stereo channels work in the same ways as their counterparts on the mono channels (faders, MUTE switches, etc.).

++ Please note: When you route a stereo channel to the subgroups using the SUB switches, please be sure to set the BAL control to its mid position, so that the signal is sent to two subgroups and remains stereo.

2.3Stereo channels 21 - 24 (SX2442FX) or 29 - 32 (SX3242FX)

Fig. 2.8: Auxiliary stereo channels

Your EURODESK has two stereo channels with an aux send section ((23) AUX 1 and AUX 2) and one LEVEL control (24). For these channels, the aux buses are hard-wired to pre-fader and are therefore particularly useful for monitoring. They have no routing switches and are always sent to the main mix. Like the normal stereo channels they have two line-level inputs on1/4" TRS connectors for the left and right channels, and a SOLO switch.

Similar to the CD/TAPE inputs (see (49)) the auxiliary stereo channels can be connected to CD players, tape decks, etc., for example, to feed in playback material.

2.4 Subgroups 1 - 4

Fig. 2.9: Subgroups 1 - 4

The EURODESK has 4 subgroups enabling you to create mono or stereo mixes from multiple input signals. Subgroups are controlled from one (mono) or two (stereo) subgroup faders. Additionally, it is possible to connect the subgroup outputs as tape sends to a multi-track recorder.

(25)The subgroup faders determine the volume of the subgroup signal at the subgroup output (28). Depending on the position of the routing switch (27) you can thus control the subgroup volume in the main mix.

(26)The SOLO switch routes the subgroup signal to the solo bus (Solo In Place) or PFL bus (Pre Fader Listen), so that you can monitor the subgroup signal without affecting the main or sub output signals. The signal to be monitored is taken either pre (PFL, mono) or post-subgroup fader(Solo, stereo), depending on the position of theSOLO/PFL switch (40)). The SOLO LED illuminates when the SOLO switch is pressed.

(27)Use the routing switches for the subgroups to send the subgroup signal to the main mix. You can route it to the left stereo side (=LEFT pressed), to the right stereo side (=RIGHT pressed) or to both (=LEFT and RIGHT pressed). For example, when you have created a stereo submix using subgroups 1 and 2, be sure to route group 1 to the left and group 2 to the right side to maintain proper stereo position- ing. If it is a mono submix with just one subgroup, route it to the left and right sides of the main mix to make the signal audible on both sides.
