EQUALIZATION
The MX.12FX has 3-band EQ on all mono channels . And all bands provide up to 15 dB boost or cut.
The MX series is equipped with one or more low-noise microphone preamplifiers
with optional phantom power providing up to 50dB of amplification. You can
connect almostany type of microphone. Dynamic microphones do not need phantom
power. Use phantom power only with condenser microphones but make sure that
phantom power switch is disengaged before connecting the microphone. Phantom
power will not damage your dynamic microphones but it may damage tube or ribbon
microphones so make sure to read the microphone instructions manual before en-
gaging phantom power switch. There are also equipped with 1/4" TRS balanced and
TS unbalanced LINE IN plug, you can connect with line-level instruments, such as
synthesizers, keyboards, drum machines or effect devices.
: Never try to connect a line-level signal to the XLR MIC input when the phantom
power is engaged, doing this you may seriously damage your equipment.
NOTE
They are organized in stereo pair and provided with 1/4" TRS sockets. It is used
to connect the stereo device, plug both the left input and the right input. Using
the left input if connect a mono input signal to the STEREO INPUT, the signal
will appear on both sides.
This GAIN control is used to control the input sensitivity of the MIC and LINE
inputs. The adjustable range goes from 0 dB to 50dB.

4- LOW CUT BUTTON
By pressing this button, you will activate a 75Hz low frequency filter that cuts the bass frequency below
75Hz. You can use this facility to reduce the hum noise infected by the mains power supply or the stage
rumble while using a microphone.
5- +4/-10 SWITCH
+4/-10 switches are used to select the input sensitivity of the line inputs on the stereo channels. +4
dBu is suitable for professional audio devices and -10 dBv is suitable for general devices. If not sure to
use which setting, try +4 dBu first, then change it to -10 dBv if the volume is too small to be satisfied.

This control is used to feed the mono input of parallel effects devices or input of a stage monitor amplifier
via the AUX SEND output jack. All the channel controls (except PAN or BAL) will affect the AUX signal. The
signal is tapped off after the LEVEL control. The output from an external processor can come back via stereo
channel and be added to the main mix.
