EURORACK MX1804X 1. INTRODUCTION Congratulations. In purchasing our EURORACK MX1804X you have acquired a mixer whose small size belies its incredible versatility and audio performance. Your EURORACK is built to the same outstanding quality as our top-of-the range console, the BEHRINGER EURODESK MX9000. One of the outstanding features of the MX1804X is its integrated, digital 24-bit effects processor.
EURORACK MX1804X Stereo aux/FX returns (additional stereo line inputs) The MX1804X features two balanced aux returns. These inputs are perfectly suited for effect returns and tape returns from multitrack machines. The aux returns may also be used for mixing in extra MIDI instruments etc. The second return usually serves for the internal effects device. But you can also use it as additional line input.
EURORACK MX1804X 1.2.4 Rack mounting the MX1804X Enclosed in the shipping box you will find a 19" rackmount kit. If you want to make your MX1804X a rack mixer, loosen the screws from the side panels and use them to fix the rack ears (note, that there is a left and a right one). + + Be sure that there is enough space around the unit for cooling and please do not place the MX1804X on high temperature devices such as power amplifiers etc. to avoid overheating.
EURORACK MX1804X adjusted, any reverb send from that channel follows the fader. Otherwise, when the fader is pulled down, the reverb from that channel would still be audible. For cueing purposes, aux sends will usually be set pre-fader, i.e. independent of the channel fader and mute. Most reverbs etc. sum internally the left and right inputs. The very few that don’t may be driven in true stereo by using 2 aux sends. There is +15 dB of gain on every aux send.
EURORACK MX1804X 2.2.4 Routing The only difference here from the mono channel described is in the implementation of the balance control . When a channel is run in stereo, this control functions as a balance control, determining the relative balance of the left and right channel signals being sent to the left and right main mix buses (or Alt 3-4). For example, with the balance control turned fully clockwise, only the right portion of the channel’s stereo signal will be routed to the main mix.
EURORACK MX1804X 2.4.2 Additional stereo line inputs and FX return There are two additional stereo line inputs (aux return operates in mono if only the left channel socket has a jack connected. ) on your MX1804X. Aux return 1 Level can be adjusted by the faders and . The returns are permanently assigned to the main mix. The aux return 2 (FX return) is usually reserved for the internal effects processor. But you can also use the FX return input connectors to return signals from external devices.
EURORACK MX1804X Although the 2-track output is primarily designed for recording, it can also be used as a PA feed, or as a send to the input of your sampler. Depressing on the rear panel will lower the level at the XLR connectors by 20 dB. 2.4.6 Monitor section Though most of you will want to audition the main mix include the Alt 3-4 bus and 2-track playback . most of the time there are exceptions. These A single volume control sends the level to the headphones and main monitors.

EURORACK MX1804X such a variety of applications that any recommendation would mean a limitation of their use. Pitch Shifter: This effect transposes the input signal to create harmonies or simply to widen the sound of a single voice. The pitch shifter effect can also be used to produce a cartoon character type voice effect. Delay & Reverb: Probably the most popular combination used for vocals, solo guitars, etc. This program uses a bright room reverb which can be used for a variety of applications.
3.3 Auditioning a signal and setting up a channels 1) Make a typical noise, or roll the tape. There should also be some activity at the main L/R bargraph meters, indicating the PFL level. 2) For mic/line inputs: Adjust the GAIN control until transient peaks are regularly hitting +6 dB. Continuous signals should not exceed 0 dB. 3) For stereo line inputs: Adjust the source’s output gain until transients are regularly hitting +6 dB. Continuous signals should not exceed 0 dB.
EURORACK MX1804X 4. APPLICATIONS 4.1 Live gig with simultaneous 2-track recording Here some or all mono channels are likely to be tied up with stage mics. Carefully position these so as to minimize feedback. Try to keep the stage volume as low as possible, as stage sound can interfere with and muddy FOH sound, as well as causing a reduction in feedback thresholds. Don’t forget to notch out troublesome frequencies using a graphic (e.g. our ULTRA-GRAPH PRO GEQ3102) or parametric equalizer (e.g.

EURORACK MX1804X but is used to split up and send one audio signal (e.g. Aux Send) to several destinations (e.g. effects devices). 4.3.3 Half-normalled Fig. 4.2: Patchbay mode “half-normalled” In this configuration, the contacts of the two jacks on the rear are interconnected. When you insert a plug into the upper front jack, the signal routed through the rear path is not interrupted.
EURORACK MX1804X 4.3.6 Patchbay organization Let us give you an example configuration that shows how you can most effectively use your patchbays. We assume you own a mixing console with 16 mic/line inputs plus inserts, 8 direct outputs, 8 subgroups with 4 inserts, 4 aux paths with 2 stereo returns and one stereo master output including insert jacks.
EURORACK MX1804X In patchbay 3 , modules 1 through 16 are for the channel insert. These modules are half-normalled, so that you have an additional route for the channel signals. The same applies to the insert paths of the subgroups and the master output. The headphones amp is connected to 23 & 24, which are normalled and connected to the control room outputs of the mixing console. Of course, you can also use pre-fader aux paths for the headphones mix.
EURORACK MX1804X 5. TECHNICAL BACKGROUND 5.1 Mixing 5.1.1 Equalization Few people buying a mixer will need to be told how an equalizer works. But how to get the best out of it? Well, that’s another story. In the beginning EQ was an instrument for removing unwanted frequencies, or compensating for imperfect microphone response curves, or bumps in a studio’s acoustic. It was a corrective device.
EURORACK MX1804X Analog multitrack tape should be driven quite hard, since its dynamic range (without noise reduction) is likely to be 20 to 30 dB worse than other elements in the recording chain. Try to record bright. You can always mix back duller. Brightening up an off-tape signal will bring up the level of tape noise. With digital tape or hard disk you have plenty of dynamic range, and treble pre-emphasis is not often necessary.
