ATI ATI PRO6 (YOM: ??) (S#: ?) GOOD (7-8)

FEATURES: DESIGNED BY ENGINEERS FOR ENGINEERS, THE ATI PRO 6 BRINGS A NEW LEVEL OF FLEXIBILITY TO ANY SOUND REPRODUCTION SYSTEM. THE PRO 6 IS SUPERB IN BOTH THE MANIPULATION OF SIMPLE AUDIO PARAMETERS AND THE CREATION OF SOPHISTICATED, DRAMATIC EFFECTS.

THE HEART OF THE PRO 6 IS A PROPRIETARY, PADLESS, HIGH VOLTAGE PREAMPLIFIER DESIGN WHOSE SONIC CHARACTERISTICS COMPLEMENT THE MOST ESOTERIC OF MICROPHONE SELECTIONS. THE PRO 6 IS FITTED WITH A FULLY PARAMETRIC, FOUR BAND EQUALIZER AND SWITCHABLE PEAKING AND SHELVING ON EACH BAND AS WELL AS 24 DB/OCTAVE HIGH AND LOW PASS FILTERS.

CLEARLY THE MOST UNIQUE FEATURE OF THE PRO 6 IS ITS PATENTED, AWARDING WINNING COMPRESSOR. THE UNIQUE DESIGN PROTECTS THE SENSITIVE HIGH FREQUENCY CONTENT OF THE AUDIO SIGNAL EVEN UNDER THE MOST VIGOROUS OF COMPRESSION RATIOS. ADDITIONAL CONTROL IS PROVIDED BY A FULLY PARAMETRIC NOISE GATE/DUCKER WITH UP TO 4 SECONDS OF DECAY AND AVAILABLE ATTENUATION EXCEEDING 60DB. THE TWO KEY FILTERS DEFINE THE BANDWIDTH OF THE GATE THRESHOLD AND THEIR OUTPUT CAN BE MONITORED FOR AUDIBLE TUNING.

THE GATE AND COMPRESSOR CONTROL VOLTAGES MAY INDIVIDUALLY BE LINKED FOR STEREO OPERATION OR WHERE MULTIPLE UNIT APPLICATION IS REQUIRED. ADDITIONALLY, THE EXTERNAL AUDIO KEY INPUTS HAVE SEPARATE JACKS FOR EACH DYNAMICS PROCESSING DEVICE. COMPREHENSIVE METERING OF AUDIO IN/OUT, GATE ATTENUATION AND COMPRESSION IS PROVIDED VIA THREE 10 SEGMENT LED LADDERS.

ALL SWITCHES USED ON THE PRO 6 ARE GOLD PLATED, SELF CLEANING AND SELF WIPING. THE POTENTIOMETERS ARE RATED FOR OVER 10,000 CYCLES AND ARE HIGH TRACK-ING. ALL RESISTORS USED IN AUDIO SIGNAL PATHS ARE 1% METALFILM. THE POWER SUPPLY IS FULLY REGULATED AND SUPPLIES ±20V TO ALL AUDIO SIGNAL PATHS ENSURING OPTIMUM HEADROOM.
