Main Control Panel
The Input area allows you to adjust the input sensitivity of each input of the amplifier, and
to change the polarity of each input, allowing you to reverse the phase of the
loudspeakers fed from that input.
The Output section allows you to control the output drive level of each amplifier. Also,
depending on which parameters have been hidden by the vendor, you may also be able
to:
•
Adjust the routing from inputs to outputs (allowing you for example to feed two
outputs from one input). Regardless of hiding, you will always be able to see the
routing in use
•
Control Bridge mode (see Bridge Mode)
•
Adjust the protection limiters (see Limiters).
The EQ / Delay tab(s) allows you to adjust the equalization, High-pass and Low-pass
filters, and delays.
The equalization allows you to adjust the frequency and Gain (boost/cut) for each of the
equalization filters, and the bandwidth of the parametric equalisers. The latter controls
allow the responsiveness of the filters to be adjusted either as Octaves or Q, depending on
the setting of Preferences>Show Bandwidth As. There is also a Low-shelf and a High-shelf
filter, each with Frequency, Slope and Gain controls.
A 'Frequency Response' curve shows the shape of each filter individually (by colour), and
the combined effect of all equalization (in white).
The Properties/Options tab contains some properties of the amplifier. Here, you can enter
a name for the amplifier (such as “Left Fill”). Also viewable in this tab are the model name
of the amplifier, and the name of the settings provided by the vendor of the factory file.
The Maintenance area shows some details of how the amplifier has been used and the
amount of protection the amplifier is applying.
The Logs area contains graphs of events against time, recording events over a period of
up to three days. Since the amplifier cannot record any events while powered-off, breaks
in a log due to power-downs are indicated by a break symbol || in the log. The events
recorded are: Thermal, which is the used thermal capacity, Protection, which is a measure
