This is the fastest way to get something out from your MX1642, if you
have a keyboard and a microphone.
a. Plug the microphone into Channel 1 MIC IN.
b. Turn down AUX and LEVEL controls on the input channel.
c. Put the EQ controls on center position.
d. Turn on your MX1642.
f. If you like, you can adjust the EQ at this stage.
g. The LED on the Master LED meter should flash only occasionally, otherwise
you will hear distortion. If this LED is not active and you still hear distortion,
please turn down a little the input LEVEL control or reduce the output level
of your source instrument.
h. Connect your stereo keyboard into one of the s channel of your
MX1642
tereo line inputs
Here you are. It is your first GIG with your MX1642.
QUICK START
Sing or speak into the microphone with normal volume and adjust the channel
LEVEL control to half.

CONTROL ELEMENTS
1- MONO MIC/LINE Channels
1
These are channels 5 through 16. They are organised in stereo pair and
provided with XLR sockets and 1/4" TRS phone jacks.If you connect only the
left jack, the input will operate in mono mode, that is the mono signal will
appear on both input channels. You can use these inputs with a stereo
keyboard, drum machine, etc.
3- STEREO INPUTS
2
This is where you connect external sound processors such as compressor-
limiter, equalizers, etc.. The insert point is available on the first 4 MIC
only.channels
2- MONO Channel INSERT
4- TRIM
3
The TRIM control is applied in the mono MIC and stereo input channels. It
provides with 2 different indications: One is for the MIC and the other for
LINE levels. When you use a microphone, you shall read the MIC ring (0~50
for mono MIC input, 0~40 for stereo channels); when you use a line level
instrument, you shall read the LINE ring (+15~-35 dB for mono MIC input,
+20~-20 dB for stereo channels). For optimum operation, you shall set this
control in a way that the PEAK LED(16) blinks only occasionally in order to
avoid distortion on the input channel.
Ok, you have got to this point and you are now in the position to successfully
operate your MX1642. However, we advise you to read the following section
carefully to be the real master of your own mixer. Not paying enough attention
to the input signal level, the routing of the signal and the assignment of the
signal will result in unwanted distortion, a corrupted signal or no sound at all.
So you should follow this procedure for every single channel:
1. Turn down all input and output gain controls.
2. Connect phantom powered microphones before switching on the +48 Volt
phantom power switch.
3. Set the output level of your or the connected power amplifier at no
more than 75%.
MX1642
5. Position EQ controls on middle position.
6. Position panoramic (PAN/BAL) control on center position.
8. Increase the input gain properly for maintaining the good headroom and ideal
dynamic range.
9. Depending on the actual application, turn slowly the input and output level
controls for obtaining the maximum gain before distortion.
INSTALLATION AND CONNECTION
4.
7. With a pair of headphone or studio monitor speakers are connected, apply a
Line Level input signal so that the PEAK LED does not light up.
Now, set the CONTROL ROOM/PHONES level at no more than 50%. In this
way, you will be able to hear later what you are doing connecting a pair of
headphones or a pair of powered studio monitor speakers.
10. Now repeat the same sequence for all input channels. The main LED meter
could move up into the red section. In this case you can adjust the overall
output level through the main mix control.
RACK mounting
In one side of the package, you will find a pair of RACK-mount. If you want to
assemble your MX1642 on a 19U RACK-box, remove the rubber handle, and fix
the RACK-mount with the attached screws
Your MX1642 is equipped with 10 low-noise
microphone preamplifier with optional phantom
power, 50 dB of Gain and over 115 dB of S/N ratio.
You can connect almost any type of microphone.
Dynamic microphones do not need phantom power.
Use phantom power only with condenser microphones
but make sure that the phantom power button is
disengaged before connecting the microphone.
Phantom power will not damage your dynamic
microphones, so make sure to read the MIC
instructions manual before engaging phantom power.
Use switch (48) to activate/deactivate phantom power.
These channels are also equipped with 1/4" TRS
balanced/unbala nced LINE-IN plugs to connect line-level
instruments such as keyboards, drum machines and
effect devices.

When you use a line level instrument, you
shall read the ring (-20~+20 dB). For
optimum operation, you shall set this
control in a way that the PEAK LED (16)
blinks only occasionally in order to avoid
distortion on the input channel.
6- LEVEL SET LED
This LED will help you to detect the input level
immediately. In this case, the research of the
fault will become much faster!
7- LOW-CUT Button
By pressing this button, you will activate a 75 Hz low frequency filter with a
slope of 18 dB per octave. You can use this facility to reduce the hum noise
infected by the mains power supply, or the stage rumble while using a

If you turn this control up, you will boost
all frequencies below 80 Hz. You will give
more punch to bass drum and bass guitar

it down, you will cut all the frequencies
below 80 Hz. In this way, you can avoid
low frequency vibrations and resonance
thus preserving the life of your woofers.

turning the fader down, which can mute the corresponding channel output except
for the channel INSERT send and SOLO (in PFL mode). And the MUTE LED will
illuminate.
Inside your MX1642, the audio signal is monitored in several different stages and
then sent to the PEAK LED. When the LED is red illuminated, it warns you that you
are reaching signal saturation and possible distortion, then you should reduce the

Each channel provides four push-buttons: SUB1-2, SUB3-4, MAIN L-R and SOLO.
Pressing the SOLO button, the corresponding SOLO LED will illuminate and the
SOLO signal will replace other signals send to the Headphone/Control Room and
Meters. Usually use the SOLO function in live work to preview channels before
they are let into the mix. It is useful to set an instrument's input level and EQ,
and you can also solo any channel that you want to. The SOLO switch never
affects any mix other than the Control Room. The other three buttons can be
considered as signal assignment switches. Pressing the SUB1-2 will assign the
channel signal to Subgroup1/2, you can depend on the PAN switch to adjust
the amount of channel signal sent to the SUB1versus SUB2, when turns the
PAN to completely left, then the signal can be only controlled by Subgroup1

the channel signal to Subgroup3/4 or MAIN MIX L/R, and will also be affected
by PAN.
