Stereo 3-way crossover
Stereo 3-way crossover:
This is one of the large range of crossover congurations which
can be achieved with the Intelli-X
2
. Factory Preset 5 is an
example of this conguration.
Input A (Left) is assigned to Outputs 1, 2 and 3, and Input B
(Right) to Outputs 4, 5 and 6. The crossover lters in the output
channels are then dened so that Output Channel 1 passes only
the low-frequency programme content, Output Channel 2 the
mid-frequencies and Output Channel 3 the high-frequencies.
Output Channels 4, 5 and 6 are then congured identically.
Input and Output Channel facilities
It can be seen from the block diagram that all input channels
are identical, and all output channels are identical, in terms of
the facilities available to the user.
Each input channel provides user-adjustable delay, gain,
polarity, both 1/3-octave graphic and 12-band parametric
equalisation, a compressor and channel muting. The input
delay is normally adjusted for time-alignment of speaker
systems distributed around a venue (i.e. under balconies, delay
towers, etc.) and the other parameters to tailor the frequency
response and dynamic range of the overall audio programme
(providing system/room EQ etc).
Note that some congurations are only possible with the Intelli-X
2
48; the limitation is imposed in all cases by the number of inputs
and outputs available. The rst of the above examples may only
be realised with the Intelli-X
2
48, as four inputs are required.
The second may be congured with either the Intelli-X
2
26 or 48.
Each output channel provides, in addition to the crossover
ltering itself, additional delays (for time alignment of individual
cabinets and drivers), and further level adjustment and dynamics
control. The parameters used in setting up the output channels
will normally be specied by the loudspeaker manufacturers,
to obtain optimum performance from the various components
making up the loudspeaker system (these settings can be
stored or recalled from the Preset Library).
