12.2 - Presets and Settings
12.2.1 - Preset Description
A variety of presets are provided within the DQ Series amplifiers to present a starting
point for your system depending on the array size. Scope is available within the DQ
Series processing for room EQ and system alignment, or alternatively a front-end
processor could also be used to perform these duties.
These presets are single-channel presets, referred to as module presets. The diagram
below illustrates how those presets work.
When selecting a preset, it is extremely important that the right preset is selected
otherwise the system will not perform as expected. The presets are based around the
TOTAL NUMBER OF ELEMENTS IN THE ARRAY – not the number of elements connected
to each amplifier channel.
To illustrate below, both the system wiring configurations below of using four HALO-C
would have the same preset recalled onto the DQ20 amplifier driving them.
As illustrated, both examples above would use the same preset file recalled into the
amplifier, all that is different is the number of amplifier channel pairs required – all of
which require the same preset recalled.
Amplifier A Amplifier A
Amplifier B
Four HALO-C, wired in parallel
Driven from one output of a DQ20 amplifier (1 channel)
Recall preset HALO-C.1-4 – preset for 1 to 4 enclosures – on one
module of amplifier A
Four HALO-C, wired individually
Driven from two outputs of two DQ20 amplifiers (4 channels)
Recall preset HALO-C.1-4 – preset for 1 to 4 enclosures – on two modules
of amplifier A and two modules of amplifier B
