User manual SABINE NAVIGATOR NAV4802-S

[. . . ] ARCHITECTS' and ENGINEERS' SPECIFICATION 2008 NAVIGATOR NAV4802-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 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. [. . . ] 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 filters4. High and low shelf filters: user-controllable cutoff points between 20 Hz and 20 kHz, and 6 or 12 dB/octave rolloff. 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. (FBX1); constant Q (filter skirts do not widen as filters get deeper). 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. CROSSOVER: Two filters per output; Bessel, LinkwitzReily, or Butterworth filters; 12, 24, 36, 48 dB/octave slopes. COMPRESSOR/LIMITER -- Threshold: +20dBu to -20dBu in 0. 5 dB steps (independently adjustable for compressor & limiter). MIXER/ROUTER -- All inputs patchable to all outputs; mixer with levels levels for all inputs/outputs PASSWORD CONFIGURATION -- 4 levels. [. . . ] 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. © 2008 Sabine, Inc Sabine, Inc. 13301 NW US Highway 441 Alachua, FL 32615-8544 (386) 418-2000 Fax: (386) 418-2001 Sabine. com 2008 Pro Audio Binder-Arch-Specs-080218. indd - ks [. . . ]
