Sabine NAV4802-S User Manual

ARCHITECTS’ and ENGI NE ERS’ SPECIFICATION

NAVIGATOR NAV4802-S 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 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 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
lters4. High and low shelf lters: user-controllable cutoff
points between 20 Hz and 20 kHz, and 6 or 12 dB/octave roll­off. 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. (FBX1); 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 innity. 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 dened, 1 factory default, 1 most recent front panel
conguration (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-S Navigator System

Processor.

Options: NAV4802-S-R: Ready for connection via
CAT-5 cable to NAVRC100 Wall-mounted Remote Control;
NAV4802-S-M: Includes Mic Preamp; NAV4802-S-MR:
Includes Mic Preamp and Remote Control. NAV4802-S-MDR:
Includes all three options; NAV4802-S-MD: Includes Mic
Preamps and Digital I/O; NAV4802-S-DR: Includes Digital

I/O and Remote Control.
