Designed for ultra-high performance in demanding applications, the
powerful monoblock designs are well-suited for amplifying independent
channels as well as for extracting the best performance from
power-hungry subwoofers. Powerful but compact, with versatile
onboard controls for input/output levels, low-pass filter, cutoff
frequency as well as level bass boost, the ZA1200 is at home in the
most advances systems.

ECLIPSE’s latest power amplifiers feature new ICEpower
®
technology. Seeing increasing use even in ultra high-end
audiophile equipment, ICEpower
®
advantages include superior
audio quality, compactness and reduced energy demand as
well as reliability. Employing ICEpower
®
analog technology in
ECLIPSE power amplifiers enable them to deliver stunning
results in terms of linearity and reduced THD, increased
dynamic range and high power stage efficiency.
In an ICEpower
®
analog circuit the analog signal is modulated into a PWM (Pulse Width Modulation) signal with the Controlled
Oscillation Modulator (COM). Then after the power stage, this PWM signal feeds back into the Multivariable Enhanced Cascade
Control (MECC) where it is compared to the original input signal and any differences are compensated for to eliminate power
stage-induced distortion. The post output filter analog signal also feeds back into the MECC that compensates for output filter
load dependent characteristics. The end result is superb sound quality free from conventional Class D limitations.
ICEpower
®
technology revitalizes the amplifier line.
