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.
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
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
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
