Installation & Connection; Audio Connection - LD Systems LAX20D Mode D'emploi

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 amplifiers, speakers, effects processor etc.
Note: the power amplifier or powered monitors shall be turned on after the mixer and turned off before the
mixer
• Set the output level of your mixer or the connected power amplifier at no more than 75%.
• Set the CONTROL ROOM/PHONE level at more than 50%.
• Position HI, MID and LOW EQ controls on middle position.
• Position panoramic (PAN/BAL) control on center position.
• While speaking into the mic (or playing the instrument), adjust the channel Level control so that the channel
pEAK LED will blink occasionally, in this way you will maintain good headroom and idea dynamic range.
• You can shape the tone of each channel by adjusting the equalizer controls as desired.
• Now repeat the same sequence for all other input channels. The main LED could move up into the red
section, in this case you can adjust the overall output level through the MAIN MIX control.
• For LAX20D, you can select desired DSP sound effects via PRESET controls.

AUDIO CONNECTION

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:
