APOGEE CRQ-12 (YOM: ?) (S#: TBD) SUPERB (8-9)

FEATURES: THE CRQ-12 PARAMETRIC EQUALIZER OFFERS A WEALTH OF POSSIBILITIES FOR SONICALLY SHAPING LARGE, COMPLEX SOUND SYSTEMS. ITS COMBINATION OF HIGH-QUALITY FILTER COMPONENTS AND CONFIGURABLE ARCHITECTURE HANDLES THE MOST DIFFICULT EQUALIZATION TASKS QUICKLY AND ACCURATELY.

THE CRQ-12 IS A "MULTI-MODE" PARAMETRIC EQUALIZER WITH THREE DISTINCT CONFIGURATIONS.
• IN THE 6/6 MODE, THE UNIT FUNCTIONS AS TWO DISCREET EQUALIZERS WITH SIX BANDS EACH. EACH CHANNEL HAS TWO INDEPENDENT OUTPUTS WITH SEPARATE LEVEL CONTROLS AND MUTE SWITCHES, 12 DB PER OCTAVE LOW-PASS AND HIGH-PASS FILTERS WITH ADJUSTABLE CORNER FREQUENCIES, AND LOW AND HIGH FREQUENCY SHELVING FILTERS, EACH WITH ADJUSTABLE TURNOVER FREQUENCY AND THE ABILITY TO BOOST AS WELL AS CUT.
• THE 6/12 MODE UTILIZES A SINGLE INPUT. THE A CHANNEL OUTPUTS ARE DEPENDENT ON THE SETTINGS OF THE FIRST SIX BANDS, WHILE THE B CHANNEL OUTPUTS REFLECT THE SETTINGS OF ALL TWELVE BANDS. EACH CHANNEL RETAINS ITS TWO INDEPENDENT LEVEL CONTROLS AS WELL AS ITS LOW-PASS, HIGH-PASS AND LOW AND HIGH SHELVING CONTROLS.
• IN THE 12/12 MODE, BOTH THE A AND B CHANNEL OUTPUTS REFLECT THE SETTINGS OF ALL TWELVE FILTERS, BUT THE TWO OUTPUT SECTIONS WITH THEIR RESPECTIVE GAIN CONTROLS, LOW AND HIGH PASS CONTROLS, AND SHELVING FILTERS REMAIN INDEPENDENT.
EACH PARAMETRIC FILTER IS FULLY ADJUSTABLE THROUGHOUT THE ENTIRE AUDIO FREQUENCY RANGE (20HZ-20KHZ), BY UTILIZING A THREE-POSITION RANGE SWITCH. EVERY BAND ALSO INCLUDES AN IN/OUT SWITCH WITH A CORRESPONDING LED INDICATOR. THE BOOST AND CUT CONTROLS FEATURE A CENTER DETENT AT THE NEUTRAL POSITION (ZERO BOOST OR CUT) AND PROVIDE A RANGE OF -20 TO +15 DB. BANDWIDTH CONTROLS ALLOW ADJUSTMENT FROM 1/25 OF AN OCTAVE TO MORE THAN 2 OCTAVES WIDE.

THE CRQ-12 UTILIZES EXTREMELY HIGH-GRADE COMPONENTS THROUGHOUT, INCLUDING PRECISION PLASTIC CONDUCTOR POTS, METAL FILM RESISTORS, POLYPROPYLENE CAPACITORS, HIGH-GRADE OP-AMPS SPECIALLY DESIGNED FOR AUDIO FILTER CIRCUITS AND A RUGGED STEEL CHASSIS. THE CRQ-12 IS COOLED BY A VARIABLE SPEED FAN FOR ABSOLUTE STABILITY OF FILTER SETTINGS REGARDLESS OF AMBIENT TEMPERATURE. A PASSIVE "HARD-WIRE" BYPASS LEVEL CONTROL IS UTILIZED ON EACH OUTPUT TO PREVENT FEEDBACK IN THE EVENT OF POWER LOSS.
