Operating the LMS-D4
With the unit mounted in a rack or cabinet, securely plug in all connections and check especially
that the Low (LF or Bass) and High (HF or Top) outputs are connected to the correct amplifiers. It is
good practice to switch on the LMS-D4 before powering up the amplifiers.
When you plug the LMS-D4 into the mains power supply, the unit will power up and the LCD
display indicates the last system loaded; the unit will be configured as it was when it was last
turned off. The current software version is also displayed for 10 seconds at start-up. The red Mute
LED will also be illuminated, as the unit powers up by default with all outputs muted.

This menu allows you to change the settings of a number of parameters, also refered to as “user
controls”. They are detailed in the next section.
...
Having entered the ‘Xover Setup’ menu, the information displayed will generally include three
fields:
1) The top row:- the output channel(s) being refered to.
2) At the left hand side of the bottom row:- the name of the parameter being edited.
3) At the right hand side of the bottom row:- the value of the parameter.
As an exception when the control is not channel related, its description will appear on the top row
(e.g. for Bass Boost).
