6 EURODESK MX2442A 2. EURODESK OVERVIEW 1. THE MANUAL Thank you for expressing your confidence in us by purchasing the EURODESK MX2442A. Our first task in writing this manual is to make you feel comfortable with the special terms that are used to describe your EURODESK MX2442A and its proper use.
7 EURODESK MX2442A The configuration is 24 into 4 into 2. This means that there are 24 channel inputs in total (there are 16 mono and four stereo channels), assignable to four subgroup buses (plus the main mix) which in turn may be blended into the main mix stereo output.
8 EURODESK MX2442A 2. 3 Power Supply Unit (PSU) In common with most desks of this size, the EURODESK has several hundreds of line level operational amplifiers (op-amps) inside. When being driven hard, many desks begin to show signs of stress due to power supply limitations.
9 EURODESK MX2442A 3. 2 Equalizer All mono input channels are fitted with a semi-parametric 3-band EQ, plus a switchable low-cut filter for eliminating unwanted subsonics. The upper and lower shelving controls have their frequencies fixed at 12 kHz and 80 Hz respectively.
10 EURODESK MX2442A 4 . STEREO INPUT CHANNELS The stereo input channel consists of almonst the same controls as the mono input channel except for the input, the EQ and the BALANCE control. For further information on the remaining controls, please refer to section 3 MONO INPUT CHANNELS.
11 EURODESK MX2442A 5 . SUBGROUPS AND INSERTS 5 . 1 Subgroups The principal routes to multitrack are via the subgroup outputs. There are four mono (or two stereo) subgroups.
12 EURODESK MX2442A + Please note that we didnt draw the ground/screen connection in the following graphics to keep them as simple as possible. + If you want to insert an external EQ or dynamics processor post-EQ, a subgroup insert should be used as follows: Fig.
13 EURODESK MX2442A + EURODESK insert points are, of course, simultaneously inputs and outputs. For goodness sake, get them onto a patchbay, where they can appear as independent sockets, and do away with all these fiddly Y-connectors that always seem to be the first to get knotted in the flightcase.
14 EURODESK MX2442A 6.2 Monitoring Though most of you will want to audition the main mix most of the time there are exceptions. These include SOLO/PFL and 2-TRACK playback . The bargraph meters follow whatever source is being auditioned (the meters wont make much sense if more than one source is selected).
15 EURODESK MX2442A The level to tape is ultimately determined by precision faders . Main mix insert points are provided for patching a gate, a compressor etc. pre-fader. This is important: Connecting a compressor or gate after the 2-track output would disrupt any attempt to acquiring a smooth fade using the output faders.
16 EURODESK MX2442A 7. 2 EURODESK MX2442A Patchfield and Plug Wiring Scheme Most of the inputs (inserts being the major exception) are balanced. + Unbalanced equipment may be connected to balanced inputs/outputs. Either use mono 1/4" jacks or connect ring and barrel of TRS jacks (or pin 1 and 3 of XLR plugs).

18 EURODESK MX2442A 8. SETTING UP 8. 1 Selecting Inputs 1) Mono channels accept mic or line level inputs. If you are using the mic input, make sure nothing is connected to the line input (and vice-versa). Please note that mic inputs are many times more sensitive than line inputs! + Do not connect mics with phantom power switched on.
19 EURODESK MX2442A 8. 4 Desk Normalization All board settings should be set to the normal default condition before or after every session. Usually faders are set to zero (minus infinity) EQs set flat, trim pots and channel aux sends turned fully anticlockwise etc.
20 EURODESK MX2442A 9. MIXING TOPICS 9.2 Gain Optimization PFL (Pre-Fader-Listening) is the way to set a desk level. Setting up the channel input gain is discussed in the essential sections 3 & 4. Optimum master aux send levels will be dependent on the sensitivity of the FX device being driven, but unity gain is a useful starting point.
21 EURODESK MX2442A 10. MODIFCATIONS 10. MODIFICATIONS The following modifications require some knowledge in soldering. Only attempt that if you are experienced in using an iron on PCBs. Otherwise, refer to qualified personnel. After modification the BEHRINGER warranty becomes discretionary.
