EURODESK MX3282A

Level to the group and main left and right busses is ultimately determined by the channel fader

. This is

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.
The MUTE button

, like that for SOLO

is ergonomically placed immediately above the channel fader,

and has an associated LED

for excellent visual status indication of this much-used feature. Engaging

mute is equivalent to setting a fader level of minus infinity. It follows that pre-fader aux sends are unaffected by

application of mute.

4. STEREO INPUT CHANNELS

Each stereo channel comes with two line level inputs on 1/4" jacks, for left and right signals. When only the left

input is connected, the channel operates in mono.

+

This feature is disabled, if the inputs and outputs of the EURODESK are wired permanently to

a patchbay (see section 9: “PATCHFIELD”).

Channel input sensitivity is variable between -20 and +20 dB by adjusting GAIN

, enabling a perfect match

with all common line-level sources including multitrack tape outputs, MIDI and other electronic instruments

and effects units, all of which are normally designed to operate at either +4 dBu or -10 dBV.

4.1 Input Level Setting

This is exactly as for a mono channel (see section 3.1).

4.2 Equalizer

All stereo input channels are fitted with four-band, fixed-frequency EQ. Bands 1 and 4 are shelving, while bands

2 and 3 have a peaking response, with their Q set at 2 octaves.
The upper

and lower

shelving controls have their turnover frequencies fixed at 12 kHz and 80 Hz,

whereas the midrange controls

and

have their bell center frequencies set at 8 kHz and 800 Hz.

All bands have up to 15 dB of cut and boost, with a center detent for “off”.

+

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.

4.3 Aux Sends

These are the same as for mono channels (see section 3.3).

4.4 Routing & Muting

The only difference here from the mono channel described in 3.4 is in the implementation of the pan control.

When a channel is run in mono, there is no difference at all.
In stereo operation however, this control functions as a BALANCE control

, determining the relative balance

of the left and right channel signals being sent to the left and right main mix buses, or odd and even subgroup

buses. For example, with the BALANCE control turned fully clockwise, only the right portion of the channel’s

stereo signal will be routed to any or all of buses R, 2, 4 etc.
