EURORACK MX2642A
1. THE MANUAL
Congratulations! In purchasing our EURORACK MX2642A 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.
The MX2642A offers you a choice of mono and stereo input channels, four assignable subgroups, and four stereo line inputs.
+This manual first describes the terminology used, so that you can fully understand the MX2642A and its functions. Please read the manual carefully and keep it for future reference.
Your EURORACK was carefully packed in the factory and the packaging is 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 during transit.
+If the unit is damaged, please do not return it to BEHRINGER, 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.
+Please make sure that all units have a proper ground connection. For your own safety, it is advisable not to remove the ground connection within the units or at the supply, or fail to make this connection at all. Please make sure that your local voltage matches the voltage required by the unit (as indicated on top of your PSU).
+Please note that both PSU and EURORACK will heat up during operation. This is completely normal and does not indicate a malfunction.
1.1 Nomenclature
Most specialist subjects are not really all that difficult provided you understand the language used, and the vocabulary of mixing is pretty straight-forward. Nevertheless it is as well to be clear about what certain terms mean. A “slot” in a recorder will always be referred to as a track, while that in a mixer will invariably be a channel. We will attempt to be as unambiguous as possible with terms, since much confusion can arise from sloppy definitions.
1.2 Keys
At the end of this manual you will find some pages with drawings showing the front and rear panel of your EURORACK respectively. Keep them turned over, lying to the left of the text pages, while studying the manual.
All functions will be numbered consistently throughout the manual, whether they be in the text or on an illustration. In addition the following prefixes will be used to denote the various types of function control in any text respectively:
Prefix |
Meaning |
S |
Switch |
L |
LED |
P |
Potentiometer |
F |
Fader |
Tab. 1.1: Prefixes and their meaning
After every prefix, you will find the function number.

1. THE MANUAL |
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 use as an aid during mixdown or a live concert mix.
2.1Architecture
Mono Input Channels
Channels 1 - 8 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. Insert points and direct outputs are also provided, giving “big console” functionality to the mono input channels.
Stereo Input Channels
A further 8 line inputs on the MX2642A are configured as 4 stereo input channels, accepting line level signals at -10 dBV (semi-pro) as well as at +4 dBu (professional) operating levels. These are ideal for multitrack tape returns, or for accepting outputs from MIDI and other electronic instruments.
Channel Outputs
A high-quality true-logarithmic 60 mm fader feeds the main via a constant-power channel PANORAMA control.
On your MX2642A, subgroup buses are fed via SUBGROUP and MIX ASSIGN switches, too. Here the channel PANORAMA control also selects between odd and even-numbered subgroup buses.
Subgroups
For ease and flexibility of mixing, four mono (two stereo) assignable subgroups are provided on your MX2642A.
Aux Sends
There are six aux send buses on the MX2642A, each with PFL.
Stereo Line Inputs
Four stereo line inputs, each with Solo/PFL, lie above the subgroup faders. These inputs are each assigned to two aux send buses. When these are used for returning tape tracks, these aux sends could be used as cue feeds to the performers’ headphones, or as effects sends for “wet” monitoring. Alternatively, the stereo line inputs could be used for MIDI instruments etc.
Main Mix Output
Main mix output level is via a high-quality true-log 60 mm stereo fader, and is monitored by a pair of accurate 12 segment bargraph peak meters, surrounded by four status LED’s. Other functions of the main section include headphones output with gain, and a 2-track tape return, which doubles as an extra stereo line input available to the mix with its own level control, completing the 26 input channels of the innovative MX2642A.
2.2Metering
Channels 1 - 8 on your MX2642A have overload LED’s, while the L and R outputs have 12 segment bargraph meters. The L/R meters double up as mono PFL or stereo solo meters.
+The master 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 main L/R LED display), reduce either the main L/R fader, the subgroup faders and/or channel faders, or (as a last resort) channel input gain. Maybe it’s time to do a round of PFL metering.
