1. INTRODUCTION
Congratulations. In purchasing our EURORACK MX802A you have acquired a mixer whose small 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.
We recommend that you experiment with your EURORACK away from the pressures of a recording session or
live concert, in order to get a feel for it. It is a musical instrument. Learn to play it well.
Next to the specifications in the appendix you will find pages with drawings showing the front and rear panels
of your EURORACK. Keep them turned over, lying to the left of the text pages, while studying the manual. All
functions are numbered consistently throughout the manual, whether in the text or on an illustration.
1.1 Architecture
Mono Input Channels
Channels 1 - 4 are mono, with a choice of balanced Mic or Line inputs. The vintage-style high-current discrete
mic amps are of the same incredible quality as those found on the acclaimed BEHRINGER EURODESK
MX9000, while a large external power supply ensures low noise and superior transient response at all times.
Stereo Input Channels
A further 4 Line inputs are configured as 2 stereo input channels. These are ideal for accepting outputs from
MIDI and other electronic instruments.
Channel Outputs
A high-quality rotary potentiometer feeds the Main Mix via a constant-power Channel Pan potentiometer.
Aux Send
There are two Aux Send busses on the MX802A, Aux 1 is pre-fader, Aux 2 is post-fader (the channel's volume
control).
Stereo Line Inputs
There are two line-level Stereo Aux Returns at the top of the output section. They can be used to return stereo
effects or MIDI instruments etc.
In addition, a stereo Tape input is provided, which may also be routed to the Main Mix, giving the MX802A a
total of 14 possible inputs during mixing. Channels 1 - 4 on the MX802A have overload LEDs, while the Main
Mix output has 12-segment bargraph meters.
1.2 Before you begin
1.2.1 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 always stay clean and
crisp right up to the operating limits of the op-amps themselves, thanks to the generous 20 W external Power
Supply Unit.
+ Connect only the provided BEHRINGER power supply unit to the MX802A. Do not connect the
PSU to the EURORACK while the PSU is connected to the mains supply. The correct starting
sequence is: connect mixer and PSU and then connect the PSU to the mains.
+ Be sure that there is enough space around the unit for cooling and please do not place the
MX802A on high temperature devices such as power amplifiers etc. to avoid overheating.
When switched on, parts of the desk and the power supply unit will become warm, this is normal
during operation.
