EURORACK MX2642A
There is +15 dB of gain on every aux send. Such a high boost is usually only appropriate where the channel
fader is set around -15 dB or lower. Here, an almost exclusively wet signal will be heard. In most consoles,
such a wet mix requires the use of a pre-setting for the channel aux send, losing fader control. With the
EURORACK you can have a virtually wet mix with fader control.
3.4 Routing, Fading and Muting
Routing means selecting which bus you want a channel to address. There are 3 stereo buses in the EURORACK
MX2642A (plus a stereo solo bus). The main L/R bus is selected by S20, while the subgroups are selected by
1-2 and 3-4 assign switches (S18, S19). All 4 stereo buses follow channel PANORAMA (P13). Usually, only
one of L/R, 1-2 or 3-4 will be selected for a particular channel.
+
An exception to this rule is when laying down voice takes. It is often convenient to have the
mic channel(s) routed to all potential take tracks simultaneously, since you are often dropping
in quickly between four or more tracks. It means one less button press each time you switch
tracks.
Level to the main L/R bus and to the group buses is ultimately determined by the channel faders (F17). These
are designed to give a smooth logarithmic taper of a type more usually associated with megabuck consoles.
The low level performance particularly is far smoother than that of a normal budget fader.
Channel PANORAMA (P13) 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
in-between. Such pin-point accuracy will be a revelation if you have been working on consoles with lower
quality circuits.
Solo/PFL we encountered in section 3.1. Solo also follows channel PANORAMA.
The MUTE button (S16) is ergonomicaliy placed immediately above the channel fader. Engaging MUTE, indicated
by L16, is equivalent to setting a fader level of minus infinity.
4. STEREO INPUT CHANNEL
Each stereo channel comes with two balanced line level inputs on 1/4" TRS jacks,
for left and
right signals,
When only the left input is connected, the channel operates in mono.
4.1 Input Level Setting
Channel input sensitivity is adjustable within a +/- 20 dB gain range (P22), enabling a perfect match with most
common sources including multitrack tape outputs, MIDI and other electronic instruments, and effects units,
all of which are normally designed to operate at -10
dBV
(semi-pro) and/or +4 dBu (pro) operating levels.
4.2 Equalizer
The stereo input channels are fitted with four-band EQ. The upper (P3), high midrange (P23), low midrange
(P23a) and lower (P6) shelving controls have their frequencies fixed at 12 kHz, 3 kHz, 500 Hz and 80 Hz
respectively.
All bands have up to +/- 15 dB of cut and boost, with a centre detent for off.
The EQ on the stereo channels is in principle identical to that on mono channels, 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.
