ARCHITECTS' and ENGINEERS' SPECIFICATION
NAVIGATOR NAV240-S System Processor
The loudspeaker controller/matrix mixer/parametric equalizer/
automatic feedback controller/compressor/limiter/delay/crossover/
signal router shall be a two input / four 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 NAV240 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 — Eight 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. High and low shelf 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.
COMPRESSOR/LIMITER — Threshold: +20dBu
to -20dBu in 0.5 dB steps (independently adjustable for
compressor & limiter). Ratio: 1:1 through infinity. Knee: soft
to hard, in 40 steps. Attack: 0.3 to 99 mSec in 1 mSec steps
Release: .05 to 100 msec. in .05 sec steps
dBu to 32 dBu in .05 dB steps.

DIGITAL DELAY — 1.47 mSec to 650 mSec in 20
microsecond steps. Edit in milliseconds, feet, or meters.
MIXER/ROUTER — All inputs patchable to all outputs;
mixer with levels levels for all inputs/outputs
PASSWORD CONFIGURATION — 4 levels
SAVE & RECALL CONFIGURATIONS — 30
user defined, 1 factory default, 1 most recent front panel
configuration (power down save).
INPUT/OUTPUT — Input impedance: balanced 10K
Ohms, PIN 2 high. Output impedance: balanced 50 Ohms
nominal, PIN 2 high. Input/output maximum signal levels:
balanced +20 dBu peak. Output load: 600 Ohms balanced.
Bypass: true power-off bypass.
PERFORMANCE — Frequency response: 20 Hz to 20
kHz, 0.1 dB @+20 dBu. Dynamic range: >115 dB. Digital
resolution: 24-bit, 48 KHz.
POWER — 50/60 Hz; 120V or 230V; 18W.
DIMENSIONS — 1-U rack mount; 19" x 1.75" x 8" (483
x 44 x 203 mm); Weight: 13.2 lb. (6 kg).
The unit shall be the Sabine NAV240-S Navigator System
Processor.
Options: NAV240-S-R: Ready for connection via CAT-5
cable to NAVRC100 Wall-mounted Remote Control; NAV240-
S-M: Includes Mic Preamp; NAV240-S-MR: Includes Mic
Preamp and Remote Control.
