Furman’s Home Theater Series Power Conditioners,
Sequencers and Distro’s feature the same robust
construction and reliability that have made our power products
preeminent within the music, broadcast, and contractor industries
for decades. Now our technology
and experience have produced a line of products specifically optimized for the demands of Home Theater.
Furman’s Home Theater Series Power
Conditioners offer many of the same
features that have made our power
products preeminent within the music,
broadcast, and contractor industries
for decades. Now, many of our standard features such as retractable rack
lights and over-under voltage shutdown,
are available with laboratory quality
Digital True RMS Voltage/Current
meters. Additionally, the HT-Series
has been optimized for today’s ultra
sensitive digital circuitry and high speed
converters. All HT series AC filters
and Transient Surge Suppressors feature our zero ground contamination
technology. This is critical for optimized
performance and trouble free performance.
Power line disturbances are real, and
they are inevitable. Many areas may
experience over one-hundred small
transient spikes a day. Additionally,
most spikes are caused by your utility and manufacturing machinery,
not dramatic events such as lightning
storms. Proper protection is essential
for costly equipment, but there is
a wide range of differences in surge
suppressors and their effect on Audio/
Video performance. In fact, typical
Surge suppressors can cause more
harm than good, by leaking the very
voltage they suppress back to your signal ground! This may cause equipment
failure over time, and will always compromise performance in today’s Home
Theater circuits.

FEATURES:
The PS-PRO HT Power Conditioner/Sequencer is
capable of powering up a rack full of equipment in a 3-step
delayed sequence. The sequence is reversed for powerdown. The sequence can be initiated with either momentary
or maintained switches, locally or remotely. A duplex outlet
is provided for each delay step. A front panel screwdriver
adjustment sets the delay time. A locking switch with a
removable key is provided for maximum security. One or
more PS-PRO HT’s may be installed in remote locations
and operated via low-voltage wiring.
The PS-PRO HT is an AC power conditioner as well. What
sets the PS-PRO HT apart from other conditioners is the
quality and configuration of the suppression devices used.
These include MOV’s, gas discharge tubes, fast-blow fuses,
and high voltage capacitors. This unique combination
can safely absorb and dissipate large spikes from nearby
lightning strikes and other sources, as well as highly attenuate audible and visible high frequency noise. An additional
feature, Extreme Voltage Shutdown, guards against wiring
faults – such as an accidental open of the Neutral wiring.
It senses voltages that are so high that operation would be
impossible (over 140V) and shuts the power down before
damage can occur. LED status indicator (“Protection OK”)
monitors the integrity of the protection devices, and reports
if the protection is compromised. The PS-PRO HT is a 19"
single space rack mount unit that comes with a ten-foot, 12
AWG power cord, and has eight widely-spaced rear outlets
that can accommodate bulky plug-mounted power supplies,
as well as a front-panel switched convenience AC outlet.

FEATURES:

combination can safely absorb and dissipate large spikes from nearby lightning strikes and other sources, as well
as highly attenuate audible and visible high frequency noise. Precise high-inrush magnetic circuit breakers avoid
the false tripping often encountered with large reactive loads like power amplifiers and powered sub-woofers. An
additional feature, Extreme Voltage Shutdown, guards against wiring faults – such as an accidental open of the
Neutral wiring. It senses voltages that are so high that operation would be impossible (over 140V) and shuts the

The PL-PRO HT is a 19" single space rack mount unit, featuring the familiar slide-out rack lights pioneered by
Furman. These light modules utilize micro switches to turn each light tube off or on automatically when pushed
in or pulled out. The PL-PRO HT is also supplied with True R.M.S. digital volt and current metering, which supply a highly accurate, reliable indication of voltage or current draw even for highly nonlinear loads like amplifiers,
switching power supplies, or when the incoming AC line is distorted. The PL-PRO HT comes with a ten-foot, 12
AWG power cord, and has eight widely-spaced rear outlets that can accommodate bulky plug-mounted power
supplies, as well as a front-panel switched convenience AC outlet.

FEATURES:
The PL-HT Power Conditioner/Light Module is the perfect accessory to any equipment rack, providing the basic
power protection essential to every audio or video system. Install a PL-HT in the top slot of your rack, and the
eight switched AC outlets on the rear panel will power all your equipment while its two slide-out light fixtures
provide discreet, illumination of their controls in any dark place. A dimmer control lets you adjust the lamp brightness to just the right level.
The Metered Six 15 Amp Series protects your delicate electronic equipment by combining a high voltage surge
and transient suppressor with an RFI/EMI interference filter. The fast-acting suppression circuit responds in
nanoseconds, clamping spikes and surges to safe levels. The filter works to prevent noise from fluorescent lights,
electric motors, radio transmitters, and similar sources of “electronic pollution” from leaking from the AC line into
sensitive analog or digital circuits.
The PL-HT lamp comes supplied with 5-watt night-light bulbs. Replacements are readily available in 4-watt sizes
at most supermarkets and hardware stores. Colored Christmas tree bulbs may also be used. Bulbs are easily
replaced without removing the unit from the rack by unscrewing the cap on the end of each light tube. The PL-HT
features a master switch for the rear outlets. This switch glows red when the power is on. There is also a separate
switch for the lamps, allowing you to check your equipment settings before applying power to it. The front-panel
circuit breaker can be easily and quickly reset should any of these units be overloaded.

FEATURES
The ASD-120 allows you to power up its six circuits in a sequenced fashion. The sequence is reversed for power
down. The overall delay interval is user-adjustable internally. For system components that present a large inductive
load to the AC line (such as power amplifiers), sequenced power can avoid excessive inrush currents that can
cause circuit breakers to falsely trip. Sequenced power is needed whenever various kinds of equipment must be
powered up or down at different times. Also, sequenced power is often necessary to allow turn-on transients from
low level preamplifiers and processors to settle down before any power amps or powered speakers are turned on.
This is because simultaneous powering can result in a loud, annoying, and potentially destructive “pop” reaching
the speakers.
The user has complete control of each of the ASD-120’s outputs. A three position front panel switch for each
control output allows it to be included in the sequence, or to be overridden. Indicator LEDs show when each
output is “on.” While the ASD-120 is ideal for controlling MINIPORTs, it can also control Furman’s PL-PRO
HT, or any other devices that need to be switched when a particular time delay has elapsed. An ASD-120 can
also control additional ASD-120’s, providing complete power sequencing control for even the largest systems.
The ASD-120 can handle up to 120 amps of incoming power, distributing it to six 20 amp, 120V circuits. Each
circuit has a front panel status indicator that lights up when it is turned on, and a 20 amp duplex outlet on the
rear panel.
The ASD-120’s design incorporates four voltage input busses, allowing wiring for 120V/240V single phase, or
208V three phase voltages. A strain relief clamp is provided that can accommodate a cable or wire bundle up to
1.5 inches in diameter. Cable termination is a simple process of breaking out and stripping the individual conductors and connecting them with set screws, and then tightening the strain relief clamp. Complete instructions accompanying the unit detail the process of selecting and terminating the supply cable. The ASD-120 provides basic
spike and surge suppression, with metal oxide varistors (MOV’s) connected between the hot and neutral conductors of each circuit. The MOV’s respond to line-coupled spikes in less than a nanosecond, clamping transient
voltages to safe levels of 200V peak or less.
