ARCHITECTS’ and ENGINEERS’ SPECIFICATION

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 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 unit shall include the following front panel indicators

(LED): Mute and Edit for each input/output, five 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; 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.

NAVIGATOR NAV480 System Processor

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

. 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 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 NAV480 Navigator System

Processor.

Options: NAV480-R: Ready for connection via CAT-5 cable

to NAVRC100 Wall-mounted Remote Control; NAV480-M:

Includes Mic Preamp; NAV480-MR: Includes Mic Preamp

and Remote Control.
