GENERAL INFORMATION
Thank you for having chosen a PROEL product.
MLX2842 and MLX3642 are large format mixers combining a large number of channels with a full set of features
designed to fit any professional sound reinforcement application.
The 20 or 28 MONO input channels feature ultra-low noise, high-headroom preamps, able to capture the full range of
any instrument. The 4-band EQ with two sweep mids has a great response for tweaking your sound in the most musical
way, while the EQ ON/OFF switch allows instant comparison. Each model includes two STEREO channels with 4-band
EQ.
The 6 AUX sends can be set pre- or post-fader in pairs. AUX sends 1 to 4, with 60mm faders and 3-band EQ, provide
effective control of the stage monitoring. AUX sends 5&6 can be routed to the two internal effects, to external outboard
or used as two additional monitor sends. Two STEREO RETURNS with full routing allow to connect external outboard or
two additional stereo instruments.
All the channels together with the four GROUPS and the MAIN MIX feature 100mm long-wearing high-quality faders for
the most accurate level control.
The MLX mixers include two 24-bit PROFEX digital effects able to provide 256 studio-grade gig-ready effect algorithms:
this allows to enhance your mix with natural high-resolution reverb or delay effects without the need of external
outboard. The effects can be selected thru a convenient LED display and they can be freely routed to the monitor sends,
the groups and the main mix.
The MLX series features a built-in USB interface to get CD quality audio to and from your computer: thru the USB
interface you can play audio files from the PC or record your live performance directly on hard-disk. The MLX USB
interface offers the possibility to route the INPUT signal directly to the MAIN MIX or to STEREO channel 2 and to get the
OUTPUT signal from the MAIN MIX or from GROUPS 1&2.
The MLX MASTER section offers plenty of services and useful features, such as a MAIN MUTE switch, a TALKBACK
section and separate PHONES and MONITOR level controls. Two or three USB sockets are available for connecting 5V
USB LAMPS.
The intuitive control surface layout and the color-coded ergonomic knobs of MLX mixers allow to locate easily each
function and makes them extremely easy to use. Both models are hosted in a rugged and road-proof metal chassis.
OPERATING INSTRUCTIONS
1. +48V phantom switch
This switch activates the phantom power on each group of 4 MIC channel inputs. Most professional condenser
microphones require phantom power, which is a lower DC voltage delivered to the microphone on pin 2 and 3 of the
XLR microphone connector. Dynamic microphones do not require phantom power, however phantom power will not
harm most dynamic microphones should you plug one in while the phantom power is on. Check the manual of your
microphone to find out for sure whether or not phantom power can damage it.
2. +48V phantom LED
This LED indicates the phantom power activation on each group of 4 MIC channel inputs.
3. MIC Input
This is a female XLR connector, which accepts a balanced microphone input from almost any type of microphone. The
XLR inputs are wire as follows:
Pin 1 = shield or ground
Pin 2 = + positive or “hot”
Pin 3 = - negative or “cold”
4. LINE Input
This is a ¼” (6.3mm) jack connector, which accepts a balanced or unbalanced line level input signal from almost any
source. When connecting a balanced signal, wire them as follows:
Tip = + positive or “hot”
Ring = - negative or “cold”
Sleeve = shield or ground
When connecting an unbalanced signal, wire them as follows:
Tip = + positive or “hot”
Sleeve = shield or ground
5. INSERT Input-output
This is where you connect serial effects such as compressors, equalizers, de-essers or filters. The nominal in/out level
is 0/+4 dBu. Specialty “Y” cables, developed just for these jacks, must be used. The ¼” (6.3mm) jack connector is wired
as follows:
