EURODESK MX3282A
2. EURODESK OVERVIEW
2.1 Architecture
The MX3282A is a conventional split console. By this we mean that the inputs and outputs occupy separate
areas of the board. This makes for easier visualization of signal path compared to an in-line design, which uses
combined input/output channels. The main section on the right hand side handles all the outputs (as well as 4
stereo aux returns and a 2-track tape input), input channels are located on the left.
The configuration is 32 into 8 into 2. This means that there are 32 channel inputs in total (there are 24 mono and
4 stereo channels), assignable to 8 subgroup buses (plus the main mix) which in turn may be blended into the
main mix stereo output. The subgroups (configurable as stereo pairs if required) are provided for connecting to
a multitrack tape recorder, or for use as a mixing aid during mix-down or during a live concert. Every channel,
and two out of four stereo aux returns included in the MX3282A can access any or all of these subgroups, or
the main mix directly, via comprehensive routing matrices. All channels also have access to eight aux send
buses. Each channel can access 6 aux sends simultaneously. For each channel the 8 aux sends are switchable
between two configurations: six pre- and two post-, or six post- and two pre-fader, for live or studio operating
environments respectively.
Input channels
The first 24 input channels are mono, with a choice of balanced mic (XLR, +48 V phantom power switchable)
or line (1/4" TRS) inputs, both with exceptional gain architecture. A further 8 line inputs are configured as 4
stereo input channels, accepting all line level signals. Every channel has MUTE, SOLO/PFL and comprehensive
EQ. A high-quality 60 mm fader feeds the main mix and/or subgroup buses via subgroup- and mix-assign
switches. A constant-power channel PAN also selects between odd and even-numbered subgroup buses.
Subgroups
For ease and flexibility of mixing, eight mono subgroups with PAN and SOLO are provided. Each has its own
individual output, and each may also be assigned to the main mix.
Aux sends
There are eight master aux send outputs, each with SOLO and GAIN.
Aux returns
Four line-level stereo aux returns, each with SOLO and GAIN, are located above the subgroup faders. Note that
AUX RETURNS 1 and 2 are assignable to any mix bus.
Stereo aux returns
At the main sections top end (middle) you will find four stereo aux returns, each with SOLO and LEVEL control.
AUX RETURN 3 and 4 are hard-wired to the main mix, while AUX RETURNS 1 and 2 can be switched to either
main mix or the subgroups and therefore are equipped with a BALANCE control.
Main mix output / additional features
Main mix output level is being controlled via a pair of high-quality 60 mm faders. The main section also includes
an assignable headphones output with LEVEL, a 2-track tape return assignable to the control room/monitors,
and a solo output, adjustable for audition level and switchable between the solo and PFL function. The monitor
(or control room) output is independently adjustable for level, and the integral TALKBACK mic is routable to
6 of the 8 aux buses, i.e. all possible pre-fader (cue) sends. A BNC connector is provided for a gooseneck lamp
for those dark winter’s night mixes.
Inserts
Mono channels, subgroups and the main mix all have insert points for patching in dynamics processors etc.
2.2 Metering
All input channels have signal and overload LEDs, while the L and R output has a pair of 12 digit bargraph
meters. The main mix (L/R) meters also have clip LEDs (+28/22 dB: balanced/unbalanced), and double up as
mono PFL or stereo solo meters, or 2-track return meters (in general, what you hear is what you see). During
Solo/PFL only the main mix bargraph meters illuminate.
