EURORACK MX802A  
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 l ine 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 be routed to the main mix or the control room 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.

1.2.2 Warranty  
Please take the time to fill out and return the warranty card within 14 days from the date of purchase, so as to  
be entitled to benefit from our extended warranty. Or use our online registration option available on the Internet  
1.2.3 Packing  
Your BEHRINGER MX802A 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, please do not return it to us, but notify your dealer and the shipping  
company immediately, otherwise claims for damage or replacement may not be granted.  
Shipping claims must be made by the consignee.  
2. MONO INPUT CHANNEL  
Each mono channel comes with an XLR mic input  
and a balanced line input on 1/4" jack  
. Phantom  
powering is switchable from the back panel  
. The gain circuit has a wide range from +10 dB to +60 dB,  
obviating the need for mic/line switching. The crucial operating input levels +4 dBu and -10 dBV are clearly and  
accurately marked  
.
2.1 Input level setting  
Mic channel input level is determined by the GAIN control  
. In addition to main mix metering, a channel  
PEAK LED  
illuminates when a channel is going into overload. These LEDs take their cue from post-EQ.  
This level sampling is particularly useful when using extreme EQ settings.  
There is no SOLO or PFL function on the MX802A. To accurately set input follow the procedures given in  
section 5: “SETTING UP”. However, if the PEAK LED does not light the input gain cannot be too high. If a  
reasonable input level is selected, auditioning a single signal should result in a reading of around 0 dB on the  
main mix meters  
, provided that both channel and output level controls are set to unity gain (0 dB).  
2.2 Equalizer  
All mono input channels are fitted with three-band EQ, plus a switchable low cut filter for eliminating unwanted  
subsonics. The upper  
respectively. The Mid Range control  
and lower  
shelving controls have their frequencies fixed at 12 kHz and 80 Hz  
has a peaking response, with Q fixed at 2 octaves, frequency at 2.5  
kHz. All three bands have up to 15 dB of cut and boost, with a centre detent for “off”. The low cut filter  
,
slope at 18 dB/oct., -3 dB at 75 Hz, is ideally suited for reducing floor rumble, breathing noises and popping,  
woolly bottom end etc.  
The combination of shelf boost at 80 Hz together with low cut at 75 Hz results in a peaking  
response, useful for adding warmth to vocals and instruments, and a firm bottom to kick drums  
and basses, without losing control of low frequency speaker cones.  
2.3 Aux sends  
Both aux sends are mono and post-EQ. Aux send 1  
is set pre-fader, while aux send 2  
is post-fader.  
For almost all FX send purposes, you will want aux sends to be post-fader, so that when a fader level is  
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.

EURORACK MX802A  
2.4 Fading and panning  
Level to the main mix bus is ultimately determined by the channel volume control  
.
Channel pan positions the output of the channel in the stereo field. Its constant-power design ensures  
there are no level discrepancies whether a signal is hard-panned, centre-stage or somewhere inbetween. Such  
pinpoint accuracy will be a revelation if you have been working on consoles with lower quality circuits.  
3. STEREO INPUT CHANNEL  
Each stereo channel comes with two balanced line level inputs on 1/4" TRS jacks  
signals. When only the left input is connected, the channel operates in mono.  
, for left and right  
3.1 Input level setting  
The stereo inputs are designed for any line level signal. Most line level sources such as MIDI instruments and  
FX units will have their own output level control. Those that don’t, like CD players, all have an output level within  
the scope of the MX802A. When the channel and master fader are set to unity gain the meters should read  
between -4 and +7 dB. Remember that there is 15 dB gain on both the channel as well as master fader.  
3.2 Equalizer  
There are no low cut filters on stereo channels, otherwise the EQ is in principle identical to that on mono  
channels (see 2.2), except that the EQ is stereo, of course!  
A stereo equalizer is generally preferable to using two mono equalizers when EQ-ing a stereo signal, as often  
discrepancies between left and right settings can occur.  
3.3 Aux sends  
It is the same as for mono channels (see 2.3). Note that a mono sum is taken from the stereo input.  
3.4 Volume control and panning/balancing  
The only difference here to the mono channel described in 2.4 is in the implementation of the balance control  
. When a channel is run in stereo, this control determines the relative balance of the left and right channel  
signals being sent to the left and right main mix buses. For example, with the balance control turned fully  
clockwise, only the right portion of the channel's stereo signal will be added to the main mix.  
If a stereo channel is run in mono (only the left input connected), the balance control acts as a pan in the  
normal way.  
4. MAIN SECTION  
4.1 Aux sends  
Aux sends are provided on unbalanced 6.3 mm jacks  
. Please adjust the input level control of your effects  
unit to match the output level of your EURORACK. This can be done when typical signals are run through the  
MX802A and the aux sends are set to center (0 dB). If your effects unit does not have an input gain and the  
effects levels seems too low, remember that every channel aux send has up to 15 dB gain, which should be  
more than enough to drive any effects unit.

EURORACK MX802A  
4.2 Stereo aux returns  
There are two additional stereo line inputs (aux returns 1 and 2) on your MX802A. Their level can be adjusted  
with and . Aux returns 1 is permanently assigned to the main mix. If you connect a jack only to the left  
socket, the aux return 1 operates in mono. Aux return 2 can be switched between the main mix and the cue  
feed (aux send 1) via a switch marked “FX TO AUX 1” . This enables you to provide a wet cue mix (signal  
with effect i.e. reverb) for the headphones or foldback speakers.  
If no connection is made to aux return 2, the signal is “normalled” (connected directly) to aux return 1. Depress-  
ing “FX TO AUX 1” will then feed the signal from aux return 1 into the cue feed (aux send 1) and can be  
controlled in level independently with aux return 2. This feature is primarily useful when you are using one effect  
for the main mix and for the foldback speakers.  
When using aux send 1 as a second (pre-fader) effects send and aux return 2 as the effect  
input, do not engage “FX TO AUX 1” . The connection from aux return 2 to aux send 1 could  
cause feedback.  
There are exceptions. For instance, when you want to send one effect into another, e.g. delay into chorus etc.  
Sometimes an engineer wants to narrow the stereo width of a reverb field. To do this you will  
have to come back on two mono channels to get independent panorama for the left and right  
signals.  
4.3 Metering  
Main mix level is displayed on a pair of accurate 12-segment bargraph peak meters  
. Two further LEDs  
indicate Power on  
and +48 V DC phantom power present  
.
The main mix bargraph meters should average around 0 dB during loud passages. If they read persistently  
higher, or are peaking above +10 dB (top segment of the display) reduce either the main mix volume and/or the  
channel volume, or (as a last resort) channel input gain or instrument / FX unit output level.  
4.4 2-track input / main mix output  
Input  
A 2-track input, on RCA phono jacks  
, provides easy connection to DAT and other professional and  
semiprofessional audio equipment. The 2-track input is primarily for auditioning mix playback from tape. Switch  
“2TK TO CTRL ROOM” routes this signal to the studio monitors. However, it can also be routed to the main  
mix via switch  
“2TK TO MIX”. Here  
should be disengaged, or you will be listening to the 2-track signal  
twice over! With  
depressed you have another stereo line input available to the mix.  
The 2-track input could be “normalled” to the output of a HiFi preamp, allowing you to monitor  
extra sources such as vinyl, cassette, CD etc.  
Output  
A single pair of electronically balanced TRS jacks  
deliver the main mix output to your 2-track recorder (or  
PA system). RCA phono jack outputs  
are also provided for easy connection to DAT, cassette desk etc.  
Level is ultimately determined by a precision main mix volume control  
.
4.5 Monitoring  
The MX802A has a separate headphone output  
. The phones signal follows the control room output  
.
A single volume control  
sends the level to the headphones and main monitors.  
The L/R meters follow the main mix.

5. SETTING UP  
Experience tells us that the cables in a studio environment get tangled very quickly (inviting mistakes). A  
patchfield will facilitate patching and repatching considerably. The BEHRINGER ULTRAPATCH PRO PX2000  
makes patching easier and trouble free, increasing both ergonomics and productivity.  
5.1 Desk normalization  
All board settings should be set to the normal default condition before or after every session. Usually volumes  
are set to zero (minus infinity), EQs set flat, and Aux Sends turned fully counter-clockwise etc.  
5.2 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 phantom power switched on  
ever! Shorting the +48 V to earth can cause serious damage.  
2) Stereo channels accept any line level signals. Any stereo channel can be run in mono simply by connect-  
ing into the left jack socket only. These channels are suitable for a variety of line-level sources including  
MIDI instruments and tape returns from multitrack.  
3) Stereo aux returns are primarily designed for returning effects units, though these too may be given over to  
tape returns or MIDI instrument outputs.  
Fig. 5.1: Setup example  
5.3 Initializing channels for gain setting  
1) Set Gain to minimum and all aux sends to off (fully counter-clockwise).  
2) Set EQ to flat (all knobs at 12 o'clock).  
3) Set the output level to unity gain (  
set to “0”).

5.4 Auditioning a signal and setting up a channel  
1) Where applicable, engage the low cut switch  
for most mics, except for signals with desired very low  
frequency content.  
2) Turn up channel volume to unity gain (  
counter-clockwise (minus infinity).  
to “0”). All other channel volume controls should be set fully  
3) Generate a signal, i.e. a voice through a microphone. There should now be some activity at the bargraph  
meters  
.
4) For mic channels: Adjust the gain control  
signals should not exceed 0 dB.  
until transient peaks are regularly hitting +6 dB. Continuous  
5) For stereo channels and other stereo line inputs, use the output volume of the source instrument or FX unit  
to effect gain adjustment until transient peaks are regularly hitting +6 dB. Continuous signals should not  
exceed 0 dB.  
6) Altering EQ will affect a channel’s gain. If EQ is adjusted at any time, repeat steps 4 or 5.  
7) Turn the channel’s volume control fully counter-clockwise. Move onto next channel and repeat steps  
1 thru 7.  
8) Once all channel inputs have been set for level, turn all active channel level controls back to 0 dB. You are  
now ready to start mixing.  
5.5 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 analog, the onset of digital distor-  
tion is as sudden as it is horrible. If you really want to take your recording level to the limit (and fully exploit 16-  
bit digital’s 96 dB dynamic range for example), you’ll have to do some calibrating. How to do it? Well, you could  
run a tone at 0 dB from the mixer and use that as your DAT or ADAT reference. But your DAT or ADAT may be  
way under its maximum input limit. Probably a better way to work out just how hard you can drive your recorder  
is to incrementally increase the record level until the onset of digital distortion, subtract, say, 5 or 10 dB, and  
never exceed that level. Engage “peak hold” on your recorder before recording if you want to confirm that you  
haven’t. Peak meters read more-or-less independent of frequency. Aim for 0 dB recording level for all signals.  
5.6 Modification  
The following modifications require you to do some soldering. Attempt only if you are experienced in using an  
iron on PCBs. Otherwise, refer to qualified personnel. After modification the BEHRINGER warranty becomes  
discretionary.  
Links should not be threaded into holes on the PCB. They should be soldered to the tinned areas around the  
holes, and bowed slightly upwards in between.  
Mono channel aux send 2 > pre-fader  
All mono channel aux sends 2 are post-fader. If you want to convert them, carry out the modification described  
below to each mono channel you want to be altered. The right PCB area is indicated by a yellow printing (see  
figures below).

ure to return the card in due time (date as per postmark) will void

3. Free inspections and maintenance/repair work are expressly  
excluded from this warranty, in particular, if caused by improper  
handling of the product by the user.  
This also applies to defects caused by normal wear and tear, in  
particular, of faders, potentiometers, keys/buttons and similar

Based on the conditions herein, the buyer may also choose to

tronic components of this product to be free of defects in mate-  
rial and workmanship for a period of one (1) year from the  
original date of purchase, in accordance with the warranty regu-  
lations described below. If the product shows any defects within  
the specified warranty period that are not due to normal wear  
and tear and/or improper handling by the user, BEHRINGER shall,  
at its sole discretion, either repair or replace the product.  
V connection or operation of the unit in any way that does not  
comply with the technical or safety regulations applicable in  
the country where the product is used.  
V damages/defects caused by force majeure or any other  
condition that is beyond the control of BEHRINGER.  
5. Any repair or opening of the unit carried out by unauthorized  
personnel (user included) will void the warranty.  
2. If the warranty claim proves to be justified, the product will be  
returned to the user freight prepaid.  
6. If an inspection of the product by BEHRINGER shows that the  
defect in question is not covered by the warranty, the inspection  
costs are payable by the customer.  
3. Warranty claims other than those indicated above are ex-  
pressly excluded.  
7. Products which do not meet the terms of this warranty will be  
repaired exclusively at the buyer’s expense. BEHRINGER will  
inform the buyer of any such circumstance. If the buyer fails to  
submit a written repair order within 6 weeks after notification,  
BEHRINGER will return the unit C.O.D. with a separate invoice  
for freight and packing. Such costs will also be invoiced sepa-  
rately when the buyer has sent in a written repair order.  
§ 3 RETURN AUTHORIZATION NUMBER  
1. To obtain warranty service, the buyer (or his authorized dealer)  
must call BEHRINGER (see enclosed list) during normal business

Failure of BEHRINGER to provide proper warranty service shall  
not entitle the buyer to claim (consequential) damages. In no  
event shall the liability of BEHRINGER exceed the invoiced value  
of the product.

comply with applicable technical or safety standards on a na-  
tional or local level, in any country which is not the country for  
which the product was originally developed and manufactured,

such modification/adaptation, irrespective of whether it was  
carried out properly or not. Under the terms of this warranty,  
BEHRINGER shall not be held responsible for any cost resulting  
from such a modification/adaptation.
