4.1. Overview
Below the Menus bar the screen comprises:
different areas corresponding to different processing functions or group of functions. Each of these areas is
located in a particular box with a black outline and a title in white capital letters (e.g. TIME DELAY).
a middle area with a dB v. frequency graph, allowing to plot the frequency response resulting from the
adjustments made to the processing parameters.
The next paragraphs contain more information on how each of those various functions can be used to set up
and optimize the sound of your car audio system.
A feature common to most areas is the use of virtual buttons with white labels on the left hand side and a
small rectangle on the right hand side mimicking a LED. This virtual LED will appear in green when the function
corresponding to the label is selected or enabled, or in light grey otherwise.
4.2. Output channel selector
The Dual Monitor amplifier includes 4 output channels:
two of those channels are the “normal” amplifier power outputs, i.e. they are intended to drive a stereo pair
of loudspeakers. They are simply referred to as Amplifier L (L for left) and Amplifier R (R for right).
the two other channels are line outputs, i.e. they are intended to feed the stereo input of an external amplifier.
They are named Line Out L and Line Out R, for the left and right channel respectively.
Selecting one or a pair of output channels is done by clicking on one of the 6 buttons laid out in the Output
channel selector box. Once a particular output channel (or stereo pair of channels) is selected, the entire
screen and all displayed parameters will refer to this channel or pair of channels. Future edition of parameters
will also apply to the same channel(s) only.
In Administrator mode, each of the 4 output channels can be individually selected (4 rightmost buttons).
In Restricted user mode, output channels can only be selected as stereo pairs (two leftmost buttons).
Note: the 30 band Equalizer operates before the crossover section (which then divides the signal path
towards the Amplifier or the Line outputs): it can be seen as located on the inputs rather than the
outputs. As such it affects simultaneously and identically the Amplifier R and Line Out R on the one
hand, Amplifier L and Line Out L on the other hand. Note that in Administrator mode it is possible to
set left and right equalizers differently.
4.3. Crossover
The CROSSOVER section is located in a box underneath the OUTPUT CHANNEL SELECTOR, on the left side
of the screen.
A virtual On/Off button is located in the upper left side of the box, enabling or bypassing the whole crossover section.
