Sabine Power-Q™ ADF4000 Adaptive Audio Signal Processor
This unit combines the functions of seven separate products into one easy-to-use 2RU package without compromising performance. Its 24-bit A/D processing and Analog Devices' new SHARC floating-point processor give the Power-Q™ unparalleled audio quality and flexibility.
Integrated features include two channels of 12-band parametric equalizer with high and low pass filters, a 31-band graphic equalizer with adjustable filter widths, up to 12-band FBX Feedback Exterminator® with adjustable sensitivity, and a real time analyzer, full-featured & filter based, with reference mic input. It also offers full-featured compressor/limiter and noise gate/expander, plus digital delay for speaker alignment.
All Power-Q™ functions operate concurrently, making it a top-quality alternative to racks full of single-function devices.
The Power-Q™ improves audio, solves tough problems, and saves money in theaters and concert halls, recording and post-production studios, houses of worship, and schools and auditoriums. Business applications include conference and board rooms, sports arenas and broadcast stations, and teleconferencing and paging systems.

FBX/PARAMETRIC FILTERS
Twelve independent digital filters per channel, controlled automatically or parametrically from 20 Hz to 20 KHz, each switchable between FBX fixed filters, FBX dynamic filters, and parametric filters.
Filter depth: user-controllable in 1 db steps from + 12db to -84db (parametric mode), 3db steps from 0db to -80db (FBX mode), maximum automatic depth adjustable from -6 to -80db.
Filter Width: user controllable from 9.99 to .01 octave (parametric), 1.0 to .01 octave (FBX).
High Pass Filter: user controllable in 1Hz steps between 20Hz and 3Khz; 12db/octave roll-off.
Low Pass Filter: user-controllable in 1Hz steps between 1KHz and 20KHz; 12db/octave roll-off.
Resolution: 1Hz from 20Hz to 20KHz in FBX and parametric mode.
Time Required to Find and Eliminate Feedback: user-controllable from 0.1 seconds to 1 second (typically 0.3 seconds).
Total Number of Combined Filters Active Per Channel: user-selectable, 0 to 12; plus low and high pass filters. Filters controllable via table or graphic interface.
