EFFORTLESS. AN AMPLIFIER'S ABILITY TO DRIVE A LOUDSPEAKER AND ACCURATELY PORTRAY A MUSICAL
COMPOSITION'S DYNAMIC CRESCENDOS IN LIFELIKE MANNER RESTS IN ITS CAPACITY TO PROVIDE INSTANT
TM
AND EFFORTLESS POWER UPON DEMAND. UTILIZING ICEPOWER POWER CONVERSION TECHNOLOGY TO
PRODUCE OVER 500 WATTS INTO 8 OHMS AND 1000 WATTS INTO 4, THE MODEL 501 EASILY SATISFIES THIS
CRITERION. BORN FROM THE SAME KNOWLEDGE AND EXPERIENCE THAT INSPIRED THE CRITICALLY-
ACCLAIMED 300 SERIES, THE MODEL 501 RAISES THE BAR TO NEW HEIGHTS IN ITS ACHIEVEMENT OF SONIC
EXCELLENCE IN A SMALL, EFFICIENT, LOW-COST PACKAGE.
EXPLODING MYTHS. JEFF ROWLAND DESIGN GROUP HAS CONVINCINGLY AND CONSISTENTLY PROVEN
THAT CAREFUL AND ENLIGHTENED EXECUTION OF DESIGN CAN OVERCOME AND REVERSE NOTIONS ONCE
THOUGHT OF AS AUDIO HERESY, i.e., LINE-LEVEL TRANSFORMERS, FULLY-BALANCED INPUTS AND OUTPUTS,
SWITCHING POWER SUPPLIES, AND THE LIST GOES ON. THE 501 DISPELS THE MYTH THAT ONLY LOW-POWER
AMPLIFIERS CAN FAITHFULLY HONOR THE ORIGINAL SOURCE.
SATISFYING DEMANDS. THE FINEST MODERN LOUDSPEAKER DESIGNS, FROM DIMINUTIVE STUDIO
MONITORS AND MASSIVE MULTI-DRIVER ARRAYS TO LARGE, FULL-RANGE ELECTROSTATICS, REQUIRE AN
UNWAVERING SOURCE OF AMPLIFIER POWER TO CONVEY MUSIC NATURALLY AND REALISTICALLY. THE
GREAT MAJORITY OF LOUDSPEAKERS PRESENT COMPLEX AND DIFFICULT LOADS THAT MUST BE DRIVEN IN A
LINEAR MANNER. THE MODEL 501 SATISFIES THIS DEMAND WHILE MAINTAINING THE PRECISION OF A
LOWER POWERED AMPLIFIER .
FLEXIBILITY. NUMEROUS MODEL 501S ARE AS CAPABLE POWERING A CUSTOM MULTI-CHANNEL HOME
THEATER SYSTEM AS TWO UNITS DRIVING A FULL-RANGE STEREO LOUDSPEAKER SYSTEM. ITS DIMINUTIVE
SIZE AND LOW OPERATING TEMPERATURE ALLOWS FOR FLEXIBLE PLACEMENT IN ANY LISTENING
