SOLO. This switch
makes a solo
of the channel by switching off (muting) all the other channels. This feature is
used to isolate the channel in order to verify the system in a test procedure and for that reason it is not used
normally when the system is operating. When using the processor as a multizone processor, this button can be
helpful to make a brief speaker solo, for testing the wiring, locating the speaker, making the EQ on a zone, etc.,
so reducing the installer time.
NOTE. Use this button carefully.
IN-01 Name label of the output. Click on this tab to a quick launching to the OTPUT DETAIL panel.
7.2.4 OUTPUT DETAIL Panel
This is the main output panel for individual adjustments.
CHANNEL NAME. Select ...to personalise the channel names. Allowed an 8 character name.
BUTTONS 1 TO 8 (MAP 128) 1 to 16 (MAP 1216). Selection of the output channel to edit.
MATRIX Section. This panel shows the ROUTING of the input channels to the selected output. Each input can be
adjusted from cancelled (-oo) to the maximum level (0dB) so making a mixing of all the inputs for each output.
FADER with bargraph. Fader movements:
-Double click on it to set to -oo dB (zero, no signal).
-Select it (changes fader color from yellow to blue) and turn your mouse wheel for setting it numerically
in 1 dB/step.
BARGRAPH Indicates de level in dBu from -40 to +20 dBu in 4 dB steps. The bar changes from green to red color
and intermediates depending on the level. Level indication includes a peak reading dot.
AUTO-MIX. Select this button on the input you want to be managed by the auto mixing system. The input that is
not included will work in manual mode so not altered by the automatic system. See more details on the menu
bar Configuration>Output auto-mix.
When an Automix is selected, one additional bargraph appears showing the gain reduction activity on this input.
The Automix system needs a lot of computing process and for this reason care must be taken not to overload it.
The Automix works on the inputs that makes a routing group for each output. It means that an input can be set
in Automix to the output #1 but this same input can be working in manual mode (not set in Automix) on the
output #2.
CROSSOVER Section. You can configure a pair of filters -HP High Pass and LP Low Pass- on any of the outputs.
Selectable filter types are: Full Range, Butterworth, Bessel and Linkwith Rilley. Select full range to make a by-pass
on this side, say you don't need a filter there. The type of filters and the selected slope depends on the
loudspeaker characteristics or composition, number of ways, etc.
When the type has been selected, set the operating crossover frequency manually or graphically on the curve by
clicking and drag on the LP and HP symbols.
XR ON. This is the by-pass button to cancel out setting to full range, the crossover filters section. A confirmation
appears just to show you the importance of this change.
NOTE. Be very carefully when selecting the HP frequency cut-off or set a crossover in by-pass as many
speaker systems can be overloaded and be destroyed when working out of band for a small time.
SIX BANDS EQ. The equaliser is composed of six bands. Each band can be tailored as:
Peq. Parametric filter with selectable Gain (dB), Freq (Hz) and Q factor (bandwidth)
Low Sh/High Sh. Shelving type filters for low frequencies or for High frequencies
Notch. The notch filter cuts out a very narrow band in the selected freq. Effect to the band is minimum.
The equalisation graph can be edited numerically or with the mouse by clicking and dragging over the band
identifier.
