EURORACK MX1604A
3. 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.
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 dont, for example CD players, all have an
output level within the scope of the MX1604A. 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
The stereo input channels are fitted with three-band EQ. The equalizer is has exactly the same parameters as
on the mono channels, in stereo. 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
These are the same as for mono channels (see 2.3). Note that a mono sum is taken from the stereo input.
3.4 Routing
When a channel is run in stereo, 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. For example, with the
Balance control turned fully clockwise, only the right portion of the channels stereo signal will be routed to the
Main Mix.
Balance also determines the relative amount of left and right channel signals being sent to buses 3 and 4
respectively when Mute / Alt 3-4 is engaged.
4. MAIN SECTION
4.1 Aux Sends
Master Aux Send levels are determined by and . These controls have a centre detent indicating unity
gain. Dont worry if your effects unit has no input gain control you have a further +15dB available from
these outputs.
4.2 Stereo Aux Returns
There are two additional stereo Line inputs (Aux Returns 1 and 2) on your MX1604A. Aux Return 1 is
permanently assigned to the Main Mix. If you connect a jack to the left socket only, 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 (signal with effect i.e. reverb) cue mix for the
headphones or foldback speakers.
