ARCHITECTS' and ENGINEERS' SPECIFICATION
NAVIGATOR NAV480-S System Processor
The loudspeaker controller/matrix mixer/parametric
equalizer/automatic feedback controller/compressor/limiter/
delay/crossover/signal router shall be a four input / eight
output digital signal processor, programmable with
the provided Windows software, Navigator Remote,
including linkable functions and remote programming.
The unit shall automatically sense feedback and determine
its pitch, then assign a digital notch filter to the resonating
frequency to automatically eliminate the feedback. It
shall effectively distinguish between music and feedback
and shall be operational during the program. The product
shall use five types of user-selectable filters: parametric,
high-shelf, low shelf, fixed FBX or dynamic FBX. The
user controls the parametric and shelving filters; the fixed
FBX filters, controlled automatically, remain set on the
initial feedback frequencies, and the dynamic FBX filters
shall be automatically reassigned new frequencies as
feedback occurs during the program. The NAV480 shall
also function as a eight-band parametric equalizer, full-
featured compressor/limiter, multi-setting crossover, and
digital delay for speaker alignment.
The back panel will have 3-pin XLR connectors for
each input and output; power connector with bulti-in
fuse holder.
The following performance criteria shall be met:
FBX/PARAMETRIC FILTERS
independent digital notch filters controlled automatically
or parametrically from 20 Hz to 20 kHz, each switchable
between FBX fixed filters, FBX dynamic filters, shelving
filters, and parametric filters
user-controllable cutoff points between 20 Hz and 20 kHz,
and 6 or 12 dB/octave roll-off. parametric filter depth:
user-controllable in 1 dB steps from +15 dB to -30 dB
(parametric mode), 3 dB steps from 0 dB to -40 dB (FBX
mode), maximum automatic depth adjustable from -6 to
-40 dB. Filter width: user-controllable from 2.50 octave
to .02 octave (parametric), 1.0 to .02 oct. (FBX); constant
Q (filter skirts do not widen as filters get deeper).
Resolution: 1 Hz from 20 Hz to 20 kHz in FBX and
parametric mode. Time required to find and eliminate
feedback: user-controllable from 0.1 seconds to 5 seconds
(typically 0.3 seconds). Total number of combined filters
active: user selectable, 0-8 per output and 0-8 per input.
Filters controllable via table or graphic interface.
CROSSOVER: Two filters per output; Bessel,
Linkwitz-Reily, or Butterworth filters; 12, 24, 36, 48 dB/
octave slopes. Multiple presets and graphic editing.
