Sabine NAV4802 User Manual
ARCHITECTS’ and ENGI NE ERS’ SPECIFICATION
NAVIGATOR NAV4802 System Processor
2008
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 from the front panel
or with provided Windows software, Navigator Remote,
including linkable functions and remote programming. The
unit shall also be accessable via programmable IP address.
The unit shall automatically sense feedback and determine
its pitch, then assign a digital notch lter 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 ve types
of user-selectable lters: parametric, high-shelf, low shelf, xed
FBX or dynamic FBX. The user controls the parametric and
shelving lters; the xed FBX lters, controlled automatically,
remain set on the initial feedback frequencies, and the dynamic
FBX lters shall be automatically reassigned new frequencies
as feedback occurs during the program. The NAV4802 shall
also function as a eight-band parametric equalizer, full-featured
compressor/limiter, multi-setting crossover, and digital delay
for speaker alignment.
The unit shall include the following front panel indicators
(LED): Mute and Edit for each input/output, ve signal level
indicators for each input/output (Signal, -12, -6, and -3 dB, and
Clip/Limit. There shall be an LCD display for all other status
and editing, two Menu keys, two Cursor keys, one Global key,
one Enter key, and one Exit key. There shall be a datawheel
for changing parameter values. The unit shall also be provided
with the following front panel connectors: USB and RS232.
The back panel will have 3-pin XLR connectors for each input
and output; RJ45 Ethernet connector; power connector with
bulti-in fuse holder.
The following performance criteria shall be met:
FBX/PARAMETRIC FILTERS — Eight independent
digital notch lters controlled automatically or parametrically
from 20 Hz to 20 kHz, each switchable between FBX xed
lters, FBX dynamic lters, shelving lters, and parametric
lters. High and low shelf lters: user-controllable cutoff points
between 20 Hz and 20 kHz, and 6 or 12 dB/octave roll-off.
parametric lter 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
(lter skirts do not widen as lters get deeper).
Resolution: 1 Hz from 20 Hz to 20 kHz in FBX and
parametric mode. Time required to nd and eliminate feedback:
user-controllable from 0.1 seconds to 5 seconds (typically
0.3 seconds). Total number of combined lters active: user
selectable, 0-8 per output and 0-8 per input. Filters controllable
via table or graphic interface.
CROSSOVER: Two lters per output; Bessel, LinkwitzReily, or Butterworth lters; 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 innity. 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. Peak limits: -20 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 dened, 1 factory default, 1 most recent front panel
conguration (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, 96 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 NAV4802 Navigator System
Processor.
Options: NAV4802-R: Ready for connection via CAT-5 cable
to NAVRC100 Wall-mounted Remote Control; NAV4802-D:
Includes Digital I/O on DB25 connector;NAV4802-M:
Includes Mic Preamp;NAV4802-MDR: includes all three
previous options. NAV4802DR: Includes Digital I/O and
Remote Control; NAV4802MR: Includes Mic Preamp and
Remote Control; NAV4802-DM: Includes Digital I/O and
Mic Preamp.
