AudioPrism's ACFX - IEC Mk II

Power Line Products by AudioPrism

Manufacturer's Description:

A high current power line filter with integrated foundation HC High current power cords on both input and output with a 15 amp or 20 amp IEC termination choice.  Note: ACFX Mk II has two switches that allow filter adjustment to match attached component.  Designed for source equipment and amplifiers.  100~240 V 50/60 Hz.  Powercord: 7ft overall with Marinco terminations.

The AudioPrism ACFX ™ Power-Line Filter improves the performance of high quality audio and video systems by reducing or eliminating the effects of electromagnetic
interference (EMI) and radio-frequency interference (RFI) on AC power supplies. At the same time, it isolates other equipment from the power supply of the amplifier or other device plugged into the filter, which reduces audio modulation distortion (AMD) and crosstalk between
audio and video components.

Unlike many power line filters which limit current, the
high current capacity ACFX ™ allows an amplifier to
perform at maximum dynamic range. An audio amplifier
plugged into an ACFX ™ has a subjectively cleaner sound
than the same amplifier connected directly to unfiltered
AC power. Bass definition is improved, midrange sound
is clearer, and high frequencies are smoother and less

All power supplies add noise to AC lines, in the form of
distortion generated by diodes alternating at the 60 Hz
line frequency. Large filter capacitors used in high-powered
amplifiers draw high charging currents, which can produce odd order harmonic distortion. As a result, most "High End" equipment generates more line noise than less costly consumer-grade equipment. Power conditioning through the ACFX ™ eliminates this form of distortion by electrically isolating your amplifier from other components.

Power line filtering improves the sound of all audio
components, including amplifiers, preamplifiers and
program source devices such as CD and DVD machines
and tuners. On virtually all video devices, filtered AC
produces less video noise and improved color saturation.

The ACFX ™ Power-Line Filter is available with either
two AC outlets (NEMA) or a captive wiring harness (IEC) to function as a dedicated power cable.

Using an ACFX ™ with each mono block amplifier greatly
enhances their sound-the effect of a separate filter for
each amplifier is quite dramatic. Isolating the amplifier
produces a wider, deeper soundstage by eliminating cross
modulation between the amplifier's power supplies.

The ACFX ™ Power-Line Filter is a product of unprecedented utility, critical performance and does
exactly what it is supposed to do-make your system sound better.
