7 EURORACK MX2642A 2 . EURORACK OVERVIEW The configuration is 26 into 4 into 2. This means that there are 26 inputs in total (8 mono and 4 stereo channels, 4 stereo line inputs, and an extra 2-track stereo input which can also be routed to the main mix. 2 stereo (or 4 mono) subgroups are provided for connecting to multitrack tape recorders, or for [...]

8 EURORACK MX2642A 2. 3 PSU (Power Supply Unit) Any amplifier circuit is limited in its transient response by the available current. Every mixer has numerous line level operational amplifiers (op-amps) inside. When being driven hard, many desks begin to show signs of stress due to power supply limitations. Not so with the EURORACK. The sound will a[...]

9 EURORACK MX2642A There is +15 dB of gain on every aux send. Such a high boost is usually only appropriate where the channel fader is set around -15 dB or lower. Here, an almost exclusively wet signal will be heard. In most consoles, such a wet mix requires the use of a pre-setting for the channel aux send, losing fader control. With the EUR[...]

10 EURORACK MX2642A 4. 3 Aux Sends These are the same as for mono channels (see 3.3). Note that a mono sum is taken from the stereo input. 4 .4 Routing The only difference here from the mono channel described in 3.4 is in the implementation of the BALANCE control. When a channel is run in stereo, this control functions as a BALANCE control, determi[...]

11 EURORACK MX2642A 5.4 Inserts Insert points are useful for adding dynamic processing or equalization to a channel, the main mix or a group. Unlike reverbs etc., which are usually added to the dry signal, dynamic processing is normally applied across an entire signal. Here an aux send would be inappropriate. Instead the signal is intercepted somew[...]

12 EURORACK MX2642A Instrument Inputs The stereo line inputs may be used as extra instrument inputs, especially if your MIDI keyboard or rack supplies a pre-mixed stereo signal. When using the stereo line inputs as extra instrument inputs, you have access to the aux buses for effects processing. Effects (Aux) Returns The stereo line inputs may be u[...]

13 EURORACK MX2642A 6. 5 2-Track Input and Output Input The 2-track input is on balanced 1/4" TRS jacks at +4 dBu, and is primarily for auditioning mix playback from tape. S46 routes this signal to the monitors. However, it can also be routed to the main mix via S44. Here S46 should be disengaged, or you will be listening to the 2-track signal[...]

The EURORACK comes supplied with this panel fixed to the rear of the unit, ready for flat-mounting the console. If you want to rack mount your EURORACK, you will probably want to re-locate[...]

16 EURORACK MX2642A 8. SETTING UP 8. 1 Selecting Inputs 1 ) Mono channels accept mic or line inputs. If you are using the mic input, make sure nothing is connected to the line input (and vice-versa). + The mic inputs are more sensitive than the line inputs. Do not connect mics with phantom power switched on. NEVER use unbalanced mic cables with the[...]

17 EURORACK MX2642A 8. 6 Recording Levels When recording to digital, its a good idea to keep the recorders peak meters below 0 dB. Most (not all, esp. samplers) read 0 dB with some headroom left. This is because, unlike with analogue, the onset of digital distortion is as sudden as it is horrible. If you really want to take your recording lev[...]
