The inputs of the MX883 can accommodate a wide range of sources
including dynamic microphones, DVD and CD players. The output may be
used to drive power (booster) amplifi ers, other mixers or mixer amplifi ers.
Each installation will require setting the appropriate relative mix of levels
between microphones and program. Also consider what the output is
driving.
Setting up correct gain structure through the whole system is important
to achieve optimal results. The following step by step procedure has been
devised to assist during the setup process. When the MX883 was shipped
to you from the factory, it was set up in a particular way. In the following
procedure it is essential that you are starting from these initial settings.
+ Program Input Gain Controls – half (12 o’clock)
+ XLR Mic/Line switch – MIC
+ XLR Phantom power - on
+ Input Level Controls – off
+ Output Level Control – off
CONNECT THE SOURCES
First connect all the required sources to the appropriate input connectors.
If the source is a microphone, set the MIC/LINE switches to the “MIC”
position. If the source is an electret or condenser microphone, set the
phantom switch to the “P/P on” position.
CONNECT THE OUTPUTS
Turn the amplifi ers off. Connect the MX883 output to the amplifi ers’ line
level input. Check that the MX883 is on, and then turn on the amplifi ers.
If the amplifi ers have a level control, set them it to a sensitivity of 0dBu.
If in doubt, set it to maximum.
SET THE LEVELS
Turn the input levels up to 5. Turn up the output level until it is at an
appropriate level for the listening environment. You will now have to adjust
the relative levels of the inputs to achieve a good balance. The aim of these
adjustments is to have all level controls at between 3 and 7. This may
not be possible however. A good rule of thumb is that input level controls
should be higher than the output level controls.
