Foreword
The Apex Intelli-X
2
is a multi-purpose system management
processor with a powerful set of DSP features. Its
applications include signal routing and distribution, room
equalisation, speaker and driver time alignment and crossover
implementation in high-quality, xed or portable sound
reinforcement and monitoring systems. It is designed to be
inserted in the signal chain between the mixing console and
the power ampliers, and can be interfaced with both analogue
and digital audio systems. It is equally applicable to FOH and
monitor applications.
Due to its extremely high quality and careful design, the
Intelli-X
2
is also eminently suitable as a room equaliser, an
active crossover or audio DA – or all three - in a studio or
cinema.
As a loudspeaker processor, the Intelli-X
2
’s primary purpose
is to act as a frequency crossover, using sophisticated lters
to split the full audio spectrum into two or more narrower
frequency bands (the number depending on the requirements
of the loudspeaker system being used). As any input can be
routed to any output, a wide variety* of common crossover
congurations can be realised with the Intelli-X
2
48, including:
• Mono, up to 8-way
• Stereo 3-way
• Stereo 4-way
• 3-channel 2-way
• 4-channel 2-way
* The range of crossover congurations available with the Intelli-X
2
26 is more
restricted than with the Intelli-X
2
48 due to the reduced I/O provision.
The crossover characteristics (usually supplied by the
manufacturer of the loudspeakers being used) can be quickly
and easily entered into the Intelli-X
2
, and then stored in the unit
for later recall. This is of great advantage with touring systems,
where the conguration of the speaker rig necessarily changes
from venue to venue.
The Intelli-X
2
’s remote control capabilities allow ne tuning of
the sound system to be carried out from a remote PC, typically
a wireless-enabled tablet PC.
