IT WAS INEVITABLE THAT THE JEFF ROWLAND DESIGN GROUP WOULD FOLLOW UP ITS PREVIOUSLY-
ACCLAIMED INTEGRATED AMPLIFIERS WITH A DESIGN THAT PROVED TO BE A SONIC CONTENDER AMONG THE
FINEST SEPARATES IN EXISTENCE. JRDGS EARLIER DESIGNS SIGNIFICANTLY RAISED QUALITY STANDARDS
AND PROVIDED COST-CONSCIOUS MUSIC LOVERS WITH A PREVIOUSLY UNAVAILABLE LEVEL OF PERFORMANCE.
THE CONCERTO INTEGRATED AMPLIFIER HAS SURPASSED THIS BENCHMARK. HOUSING AN EXTREMELY
EFFICIENT ICEPOWER-„˘ OUTPUT SECTION PRODUCING OVER 250 WATTS PER CHANNEL, THE CONCERTO HAS
THE ABILITY TO DRIVE ANY LOUDSPEAKER TO MORE THAN ADEQUATE OUTPUT LEVELS WHILE ALWAYS
REMAINING ONLY WARM TO THE TOUCH. COUPLED WITH A PREAMPLIFIER CIRCUIT EQUIVALENT TO THE
CONCERTO PREAMP, THE INTEGRATED AMPLIFIER ECONOMICALLY APPROACHES THE PERFORMANCE OF JRDG
SEPARATES.
THIS PRODUCT REPRESENTS THE SUM TOTAL KNOWLEDGE OF JEFF ROWLAND DESIGN GROUP'S HERITAGE OF
FINE PREAMPLIFIER AND AMPLIFIER DESIGN IN A SLIM, ELEGANT CHASSIS. FEATURING PREAMP BYPASS
INPUTS, DUAL LINE-LEVEL OUTPUTS, BALANCED AND UNBALANCED TRANSFORMER-COUPLED INPUTS, AND
EXTREMELY HIGH ENERGY EFFICIENCY, THE CONCERTO INTEGRATED AMPLIFIER IS POISED TO BE THE
CENTERPIECE OF AN OUTSTANDING TWO-CHANNEL STEREO OR CUSTOM INSTALLED THEATER SYSTEM.
THE MOST COMMONLY USED FEATURES OF THE CONCERTO CAN BE CONTROLLED WITH AN EASY TO USE, SIX
FUNCTION, HAND-HELD IR REMOTE CONTROL WHILE A DUAL RATE VOLUME CONTROL ALLOWS PRECISION
LEVEL ADJUSTMENTS OVER NEARLY A 100 dB RANGE. THE VOLUME CONTROL INCORPORATES A PERMANENTLY
NOISELESS OPTICAL ENCODER THAT WILL ALWAYS MAINTAIN ITS TACTILE FEEL, ACCURACY, AND CHANNEL
BALANCE AT ALL SETTINGS.
JEFF ROWLAND DESIGN GROUPS CONCERTO, AN INTEGRATED AMPLIFIER MUCH GREATER AND SATISFYING
THAN THE SUM OF ITS PARTS.
