7 EURORACK MX3242X 1 . INTRODUCTION Congratulations! In purchasing the BEHRINGER EURORACK MX3242X you have acquired a mixing console whose compact size belies its incredible versatility and superlative audio performance. Your EURORACK is built to the same outstanding quality as our top-of-the-range console, the BEHRINGER EURODESK MX9000. With its 1[...]

8 EURORACK MX3242X 1.1.1 Architecture Main input channels Channels 1 through 16 are configured as mono channels with balanced Microphone and Line connectors. The discrete vintage-type microphone preamps in high-current technology have the same excellent quality as the amplifiers in our legendary BEHRINGER EURODESK MX9000. An overdimensioned e[...]

9 EURORACK MX3242X Each of the Main input channels, the Subgroups and the Main Mix bus are equipped with 8-segment, 3-color LED level meters ( , and ), which help you set levels correctly and avoid distortion. When your MX3242X is shipped from the factory, the level meters are configured post-fader, but can also be modified to display pre-fader sig[...]

10 EURORACK MX3242X 1.2.4 Shipping Your EURORACK MX3242X was carefully packed in the factory and the packaging was designed to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage, which may have occurred in transit. + If the unit is damaged, plea[...]

11 EURORACK MX3242X Each mono channel features a balanced Line input on a ¼" jack and a balanced Microphone input on an XLR connector . Fig. 2.2: Phantom power switch The +48 V phantom power required for condenser mics can be activated with the phantom power button i n the Main section. If activated, the LED next to the button lights up. + Mu[...]

12 EURORACK MX3242X 2.1.2 Equalizer Fig. 2.4: Equalizer In addition to the Lo Cut filter, all Main input channels come with a 4-band Equalizer with two tunable midrange bands, each having up to 15 dB of cut and boost. In center detent position the EQ is off. With the EQ IN button you can activate/bypass the Equalizer, so as to allow for easy [...]

13 EURORACK MX3242X All Aux Sends are mono, post-EQ and post-mute. To make sure that the signal form the Main input channel is sent to the Aux bus, SOURCE buttons and should be up (not pressed). However, you can also split the Aux buses and use them both for the Main input channel and for the Mix-B channel. Aux Sends 1 and 2 can be set either pre o[...]

14 EURORACK MX3242X These are designed to give a smooth logarithmic taper of a type more usually associated with megabuck consoles. The performance, even at low levels, is far smoother than that of a normal budget fader. The PANORAMA control positions the output of the channel in the stereo field. Its constant-power design ensures there are n[...]

15 EURORACK MX3242X 2.2.3 Routing Fig. 2.8: Controlling the Mix-B signal Each Mix-B input channel has a PANORAMA and LEVEL control as well as a MUTE button . All signals from a Mix-B channel are routed to the Mix-B bus and are available from the MIX-B OUT jack o n the interface panel. Their overall volume is determined by the LEVEL control in the M[...]

Their level can be adjusted with the master controls for Aux Sends 1 through 6 located in the Main section. Beyond the center detent position (unity gain), these controls give you up to 15 dB gain, which should be mo[...]

For example, they can return the signal of a multi-track recorder (Tape Returns), or act as inputs for instruments, especially when your MIDI keyboard or rack delivers a pre-mixed stereo signal. 2.4.3 Level meters The Main Mix / PFL / SOLO level is displayed by two highly accurate 8-segment peak meters . Depending on the[...]

19 EURORACK MX3242X 2.4.6 Monitor section Fig. 2.15: Monitor section The buttons 2-TRACK and MIX-B determine which signal is sent to the MON OUTputs , where you can connect active or passive speakers (plus power amp). If neither one of the buttons is pressed, the outputs provide the Main Mix signal. The 2-TRACK button allows you to monitor the sign[...]

20 EURORACK MX3242X 2.4.8 Subgroups and Main Mix f ader Fig. 2.17: Subgroups section In a recording situation, the inputs of a multi-track recorder are fed with signals from the Subgroup outputs . The 4 Subgroups, in turn, can be fed by the Main input channels and the Aux Return buses. In this way, you can also record effect signals. The faders con[...]

21 EURORACK MX3242X A very special feature of your MX3242X is its on-board Effects Processor, which offers the same hard/software quality as our well-known 19" VIRTUALIZER DSP1024P. This effects module provides 32 different standard effects such as Reverb, Chorus, Flanger, Delay, Pitch Shifter and various effects combinations. Use Aux Send 3 ([...]

22 EURORACK MX3242X Echo: Much like the Delay effect, echo repeats the input signal with decaying intensity. However, here the echoes lose brilliance with each repetition, which simulates the trendy vintage effect produced by tape echo units that were widely used in the pre-digital era.

23 EURORACK MX3242X 3. PRACTISE 3.1 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). 2) Mic inputs are more sensitive than Line inputs. Do not connect microphones with Phantom Power switched on. 3.2 Initializing channels for gain setting [...]

Please select monitor bus Mix-B in the MON/CTRL section, so that you can control the tape return signals using the LEVEL and PAN controls of the Mix-B input channels. + In a recording situation the recorded material should always be monitored via the Tape Return bus. The same applies to the monitor mi[...]

29 EURORACK MX3242X 4.3.7 Looming problems Loom wiring is an art unto itself, and it is worth taking time out to get it right. First off, it is important to avoid earth loops (a looped wire acts an aerial, picking up hum and electromagnetic radiation). Think of a tree. Every part of that tree is connected to every other part, but only by one route.[...]
