CONTROL eLeMentS:
1THE MONO MIC/LINE CHANNELS
You can connect balanced, low impedance microphones or a low
level signal to the XLR socket. On the 1/4 “ line jack you can connect
either a microphone or a line level instrument such as synthesizers,
drum machines, effect processors or any other line level signal.
Note: You shall never connect an unbalanced microphone to the XLR
socket if you do not want to damage both the microphone and mixer.
Also, it is not possible to simultaneously use both the MIC & LINE
inputs on the same channel, use only one of them for the appropriate
source.
2INPUT LEVEL SETTING
This control is provided with 2 different indication rings: one is for
the microphone and the other for the line level. When you use a
microphoneyoushallreadtheOUTSIDEring(0~40dB),whenyou
use a line level instrument you shall set this control in a way that the
peak LED will blink also occasionally in order to avoid distortion on
the input channel.

AUX1 can be configured as PRE/POST fader via the PRE/POST switch.
Up for POST fader, the signal is sent out after the channel fader and
will be affected by the channel fader. Down for PRE fader, the signal
is sent out before the channel fader and will not be affected by the
channel fader. AUX2 is configured as PRE fader through internal
modification.

INSTALLATION & COnneCtiOn:
Ok, you have got to this point and you are now in the position to successfully operate your XM-20/20D, however,
we advise you to read carefully the following section to be the real master of your own mixer. Not paying enough
attention to the input signal level, to 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 these procedures for every single
channel:
•Beforeconnectingmicsorinstruments,makesurethatthepowerofallyoursystemscomponentsincluding
the mixer is turned off. Also, make sure that all input and output controls of your mixer are turned down. This
will avoid damage to your speakers and avoid excessive noise.
•Properlyconnectallexternaldevicessuchasmics,powerampliers,speakers,effectsprocessoretc.
Note: the power amplifier or powered monitors shall be turned on after the mixer and turned off before the
mixer

BothXLRand1/4’’TRSconnectorsareavailableontheunit.Inthiswayyoucaninterfacetheunitinseveral
different ways without experiencing any noise or signal loss. You can use the unit with single instruments using
the mixer’s main insert or on “in-line” between a mixing console’s output and a power amplifier.
WIRING CONFIGURATION
Either the 1/4‘’ TRS phone jack or XLR connector can be wired in balanced and unbalanced modes, which will
be determined by the actual application status, please wire your system as the following wiring example:
