The system example below is also intended to illustrate how the preset relates to the
length of the array, not the number of enclosures connected to the amplifier channel.
Twelve HALO-C, wired as three groups of four in parallel
Driven from three outputs across two DQ20 amplifiers
(3 channels)
Recall preset HALO-C.9-16 – preset for 9 to 16 enclosures – on two
modules of amplifier A and one of amplifier B.
As illustrated, regardless of the combination of amplifiers used, or how the loudspeakers
are wired, the preset to be recalled is determined by the number of elements in the array.
Amplifier A
Amplifier B
Twelve HALO-C, wired as six groups of two in parallel
Driven from six outputs of three DQ20 amplifiers (6 channels)
Recall preset HALO-C.9-16 – preset for 9 to 16 enclosures – on two
