Celebrating Twenty Years of Audio.
Presenting the 4x4 PRO SERIES Power Distribution Systems
from ART. Built on the foundation of the popular 4x4s, the
PRO SERIES are durably constructed, reliable power
conditioners for use in many applications. Wherever power
management system is required, the 4x4 PRO SERIES provide
the surge protection you need to keep your rack safe from
unwanted disruption.
ALL PRO SERIES models
have an additional internal
discrete module called
APF™ (Advanced Power
Filtering) which filters out
digital and dimmer hash as
well as any high frequency noise that is above the
audio range. Some off-the-shelf add-on modules
saturate and lose their filtering effectiveness as the load
increases, but by using a high power discrete design we
were able to create a filter that stays effective over the
full operating range.
By using both Common Mode and Differential Mode topolo-
gies in series for the filter design we are able to block virtually
all of the unwanted noise that is between the AC line and
ground, and also the two sides of the AC line. This has the
additional benefit of reducing ground loop problems in your
system.
High frequency noise currents in particular are highly attenu-
ated in both directions so that any line noise that could be
generated by one of your components is not allowed to get
back into your main A.C. wiring so if you use a number
of PRO SERIES Power Conditioners in your setup, you can
distribute and isolate the noisy components from the sensitive
components in your system. Additionally, any signals above
10kHz are filtered from the line with over 40dB of attenuation
above 100kHz and beyond.
Every PRO SERIES power conditioner is designed with
a power capacity of 1800 Watts, surge/spike protection,
APF with EMI & RFI filtering, front-mounted unswitched power
outlet and an adjustable rear-mounted gooseneck light source
for bright illumination behind the rack. The spacing and align-
ment of the rear outlets to accommodate various size power
plugs and AC adapters.
The SP4x4 and PS4x4 are equipped with pull-out light pipe
lamps with an “auto-off” microswitch built-in for a quicker shut
down. The SP4x4 provides an LED input voltage monitoring
display while the PS4x4 provides an additional LED load
current monitor display.
