PS-PRO II - POWER CONDITIONER / SEquENCER
is particularly suited to applications where large
installations must be switched by inexperienced
personnel.
lIFT (linear filtering
technology)
The PS-PRO II is controlled by a front panel
key-operated switch to provide security from
non-authorized users tampering with the sys-
tem. The switch has three positions: OFF, ON,
and REM, allowing for local or remote control.
With remote control, one or more PS-PRO II’s
may be installed in remote locations with on/off
control and LED monitoring via low-voltage
control wires.
Unfortunately, traditional AC filter - conditioners
have been designed for unrealistic laboratory
conditions. Prior technologies, whether multiple
pole filter or conventional series mode, could
actually harm audio and video performance
more than they help, due to the resonant peaking
of their antiquated, non-linear designs. Under
certain conditions, these designs can actually
add more than 10 dB of noise to the incoming
AC line! Worse still, lost digital data, the need
to re-boot digital pre-sets, or destroyed digital
converters are frequently caused by excessive
voltage spikes and AC noise contaminating the
equipment ground. Furman’s SMP+ with LiFT
takes another approach, ensuring optimal per-
formance through linear filtering and no leakage
to ground.
Besides its power sequencing capabilities, the
PS-PRO II contains many other conditioning and
protection features. Each aspect of its functioning
will be discussed in the next sections.
INSTallaTION
RECOmmENDaTIONS
In audio/video installations, we recommend that
power amps receive power last — plug them all
into Delay 3 or divide them into two groups and
plug one group through Delay 2 and the other
through Delay 3. Low level equipment such as
mixers and signal processors should use Delay
1. Equipment incorporating clocks or timers such
as VCR’s, or equipment that must respond to
wireless remote actuation, should use the un-
switched outlets. We suggest keeping the front
panel's unswitched outlet free for equipment that
is only in use temporarily.
DESCRIPTION
The PS-PRO II is a power sequencer, meaning it
is capable of powering a rack full of equipment in
three steps separated by timed delays. It is use-
ful whenever various kinds of equipment must
be powered up or down in groups, rather than
simultaneously. In audio systems, sequenced
powering is often necessary to allow turn-on
transients from low level amplifiers and pro-
cessors to settle down before any power amps
are turned on, because simultaneous powering
would result in a loud, annoying, and potentially
destructive “pop” reaching the speakers. And in
any large system whose components present an
inductive load to the AC line (including electric
motors, power supplies, and power amplifiers
of all kinds), sequenced powering can avoid
excessive inrush currents that can cause circuit
breakers to trip, even though the steady-state
currents are not excessive. Power sequencing
The overall capacity of the PS-PRO II is 20 amps.
This refers to the combined steady-state current
drawn by all devices plugged into all of its nine
outlets. If this combined current level exceeds
20 amps at any time, the circuit breaker will trip,
cutting off power to your rack. If this occurs, you
must reduce the load by unplugging one or more
units from the PS-PRO II. Then push the black
button on the circuit breaker (on the front panel)
to reset it.

PS-PRO II - POWER CONDITIONER / SEquENCER
Although 20 amps is an absolute limit, the
PS-PRO II will allow you to come as close as
possible to using the full 20 amps, because
with power sequencing, the risk of tripping
the breaker is greatly reduced. The PS-PRO
II handles large but temporary inrush currents
in stages, rather than simultaneously, allowing
each stage to settle to its steady-state current
draw before the next stage is powered.
front panel Delay Adjust control.
The Delay Adjust control, which can be set us-
ing a screwdriver, controls the total delay time
between Delay 2 and Delay 3. For example, if
the Delay Adjust is set for 30 seconds, the De-
lay 1 outlets will go on immediately, Delay 2 will
power 15 seconds later and Delay 3 will power
15 seconds after Delay 2, for a total delay time
of 30 seconds.
Outlets and Plugs: The PS-PRO II’s four rear
panel outlet pairs are standard 120V, 20Aduplex
types. These outlets are widely spaced, to ac-
commodate one bulky plug-mounted “wall wart”
power supply in each without covering up an
adjacent outlet. The front panel outlet is limited
to 15 amp use. The PS-PRO II also uses a 20
amp line cord, identified by the perpendicular
blades on the plug. In 20 amp products, use
of a plug of this type is required for UL safety
certification. It is compatible with 20 amp outlets
(such as those on the rear panel of the PS-PRO
II). For more information about 20 amp plugs,
see the information sheet “What Kind Of Plug Is
This, Anyway?” accompanying this manual, or
request a copy from Furman.
The order is reversed for the OFF sequence.
For example, when an OFF sequence is initiated
and the DelayAdjust control is set at 60 seconds,
Delay 3 outlets lose power immediately, Delay 2
outlets lose power 30 seconds later and Delay
1 outlets lose power 30 seconds after Delay 2.
The total delay time is 60 seconds.
In the event of a power outage, of course all
equipment plugged into a PS-PRO II will lose
power simultaneously. However, when power
is restored, the delayed outlet groups will again
turn on in the usual delayed sequence (if set to
maintained on mode).

FEaTuRES
The method of initiating an ON or OFF sequence
depends on whether the unit is to be controlled
locally or remotely. If remotely, it further
depends on the type of switch or switches used
(momentary or maintained).
The PS-PRO II rear panel provides one un-
switched and three switched outlet pairs. The
switched outlet pairs are labeled Delay 1, Delay
2, and Delay 3. (The other pair of outlets on the
rear panel and an additional single outlet on the
front panel are unswitched.)
LOCAL CONTROL
For local control, an ON sequence is initiated
by turning the key switch to the ON position,
and an OFF sequence by turning the key
switch to OFF position. The START ON-OFF
SEQUENCE pushbutton is not normally used
in local operation.
Here’s how the PS-PRO II works: When an
ON sequence is initiated, power is immediately
applied to the Delay 1 outlets. Power is then
applied to Delay 2 and Delay 3 outlets per the
1-60 second total delay setting selected with the

terminals (PCB REV D and later) labeled as:
local control only, and a jumper is installed
on JMP1 with no switch connected to the PS-
PRO II’s terminal strip, then a jumper should
be connected between the REM and +12V
terminals. Otherwise, turning the front panel
key switch to the REM position will turn the PS-
PRO II ON.
JMP1 (Default) (MAINTON) , when the REM and
+12V terminals are tied together, the PS-PRO II
will sequence OFF.
JMP2 (MOMENTARy), when the REM and +12V
terminals are momentary tied together, the PS-
PRO II will sequence ON or OFF.
JMP3 (MAINT OFF), when the REM and +12V
terminals are tied together, the PS-PRO II will
sequence ON.
REMOTE CONTROL
When the PS-PRO II’s front panel key lock switch
is in the REM position, it can be controlled by
one or more switches in remote locations. In
the most basic configuration, only two wires
and an SPST switch are needed to initiate an
ON or OFF sequence. The switch may be either
a momentary or a maintained-contact type,
depending on a jumper setting inside the PS-
PRO II. If an additional wire is used, an LED may
also be installed at the remote end to indicate
that the power is on.
JMP4 (REM TO GND = ON), when the REM and
GND terminals are tied together, the PS-PRO
II will sequence ON (Note: JMP1 must have a
jumper installed).

An on-off switch of either kind may be used
to actuate the PS-PRO II’s remote operation.
Maintained switches, such as most toggle
switches and push-on/push-off button switches,
(including the Furman RS-1 key lock switch),
stay open until switched, and then remain closed
until switched again. Momentary switches,
usually pushbutton types like the Furman RS-2
(which also provides a locking key switch), are
normally open and stay closed only as long as
the button is pressed.
JUMPER SETTING CHART
PS-PRO II units come factory-set for maintained
operation (jumper is installed on JMP1). They
may be easily converted to other operating
modes by moving jumper plug/plugs on the PS-
PRO II’s circuit board. To do this, first disconnect
the unit from AC power. Remove the 12 screws
that secure the top cover. Simply install the
jumper plugs to the desired mode of operation.
Reattach the top cover.
Maintained switches are generally the most
convenient when there is only one remote
location.Whenmorethanonelocationisrequired,
momentary switches offer the advantage of
a turn-on or turn-off sequence which may be
started from any location.

units feature a rear rack BNC socket which will
accept any 12 VAC (0.5A) gooseneck lamp as-
sembly, (such as the Furman GN-LED or GN-I).
Simply slide the BNC plug over the socket and
rotate clockwise until the connector snaps into
the locked position. The rear rack lamp can be
powered on or off with the rear light power switch
located on the far left of the front panel.
ThePS-PROIIsensesvoltagesthataresohighor
lowthatoperationwouldbeimpossible(under80V
or over 140V) and shuts the power down before
damage can occur. Upon initially applying power
to the PS-PRO II, this indicator will be lit if the unit
is receiving below 80 volts or more than 140 volts,
and power will not be applied to the PS-PRO II’s
outlets. If the unit has been operating with an ac-
ceptable input voltage and then the voltage goes
outoftheacceptablerange,thePS-PROIIwillshut
down power to all of its switched outlets simulta-
neously, without observing the OFF delay cycle,
and this LED will begin flashing. When power re-
turns to within the acceptable range, the PS-PRO
II will observe its ON delays as it returns power to
its switched outlets, and this LED will go out.
NOTE: If the mains power is below 80 volts and
has caused the PS-PRO II to remove power
from its outlets, the PS-PRO II will not restore
power to its outlets until the mains voltage is
more than 90 volts. If the mains power is above
140 volts and has caused the PS-PRO II to re-
move power from its outlets, the PS-PRO II will
not restore power to its outlets until the mains
voltage is less than 130 volts. The reason for
this is to prevent the power from oscillating on
and off in marginal conditions.
STaRT ON/OFF SEquENCE: This pushbutton
switch is used only when the key lock switch is
in REM position and the PS-PRO II is in Mo-
mentary Mode. It then acts the same as any
other remote momentary switch that may be
connected to the rear panel terminal strip. If the
switched outlets are on, pushing it begins an
OFF sequence. If they are off, pushing it begins
an ON sequence. Do not use this switch when
in Maintained Mode.
PROTECTION OK: This LED is normally on
when the power to the PS-PRO II’s outlets is
switched on. It monitors the integrity of the pro-
tection devices and reports if the protection is
compromised. If an extremely large spike is en-
countered that exceeds the PS-PRO II’s capac-
ity, the main group of input protectors will blow
an internal fuse, causing the indicator to go out.
If this LED is not lit when the power switch is on,
full protection is not functioning. Spike protection
may still exist, but will have a reduced capacity
to absorb current. If this LED is not lit, please
contact the Furman Service Department.
DElaY aDJuST: This screwdriver-adjustable
trimpot allows you to set the total turn-on/turn-off
delay time from 1 to 60 seconds, as explained
on page 6. The trimpot adjusts both the on
delay and off delay times simultaneously. Turn
the trimpot clockwise to increase the on and off
delay times; turn the trimpot counterclockwise
to decrease the delay times.

power to your rack. If this occurs, reduce the
load by unplugging one or more units from the
PS-PRO II, and reset it. you can reset the circuit
breaker by simply pressing the button, which
pops out when tripped. However, because it
is a thermal type, you may have to wait a few
moments after it trips for it to cool down before
it will allow you to reset it.
POWER STaTuS (DElaY) lEDs: One green
LED is provided for each of the three delay
stages. Each LED lights when power is applied
to its corresponding duplex outlet on the rear
panel. All three LEDs then remain lit until power
is removed. During the power-down delay cycle,
each LED goes off as power to its correspond-
ing outlet is removed. In addition, the Delay 1
LED flashes if a remote switch (or the stored
state) is OFF.
ON/REm/OFF SWITCH: When turned to the
ON position, this key lock switch initiates an
ON sequence, applying power to the PS-PRO
II’s switched outlets. When turned to the OFF
position, it begins an OFF sequence. In the
REM position, the PS-PRO II will accept on/off
commands from a remote switch or switches that

NOTE: DO NOT USE the “START ON-OFF
(Continued from p.4)
SEQUENCE” switch on the front panel in
Maintained Mode . If you do, you may activate
an unintended sequence. If a Furman RS-1 is
the controlling switch, contact Furman’s Tech
Support department for the proper wiring
diagrams.
MAINTAINED MODE
There are 3 maintained modes of operation:
REM to +12V = OFF (jumper plug installed on
JMP1, MAINT ON)
The connection of the REM terminal to the
+12V terminal initiates an OFF sequence.
Disconnecting initiates an ON sequence. If
the cable run is long, it is recommended that
the REM wire be tied to the PS-PRO II’s GND
terminal during ON operation rather than leaving
it floating. This will require the use of a third
conductor and a double-throw switch.
MOMENTARy MODE
In Momentary Mode (jumper plug installed on
JMP2)
The PS-PRO II has “memory” — it only needs
a momentary signal from the remote switch to
change its state from ON to OFF. When first
plugged in (or after power is lost and reapplied
for any reason) the stored state is OFF, and the
DELAy 1 LED will flash. The unit will stay off
until sequenced ON by a momentary connection
of the REM IN terminal to +12V (the key switch
must be in the REM position). The sequence
starts on the rising edge of the signal.
REM to +12V = ON (jumper plug installed on
JMP3, MAINT OFF)
The connection of the REM terminal to the +12V
terminalinitiatesanONsequence. Disconnecting
initiates an OFF sequence. If the cable run is
long, it is recommended that the REM wire be
tied to the PS-PRO II’s GND terminal during OFF
operation rather than leaving it floating.
The front panel START ON-OFF SEQUENCE
switch is in parallel with, and functionally
equivalent to, one or more remote momentary
switches that may be connected to the terminal
strip in the rear.
REM to GND = ON (jumper plugs installed on
JMP1 and JMP4)
The connection of the REM terminal to the GND
terminalinitiatesanONsequence. Disconnecting
initiates an OFF sequence.
The “memory” is independent of the key switch.
This means that even if the unit is sequenced off
by turning the key lock switch to OFF, when the
key lock switch is turned back to REM, the unit
will sequence back on — it will not be necessary
to push the START ON-OFF SEQUENCE button
again. The unit “remembers” its state until the
incoming power is lost, in which case it would
default back to OFF.

MOMENTARy MODE
contact switch, the RS-1 is not an appropriate
remote switch for the PS-PRO II when it is in
momentary mode. The Furman RS-2 is the
proper choice. Please contact Furman for RS-2
wiring diagrams.
Holding the REM line high for at least 4 seconds
(whether by an actual remote switch or by any
unit’s START ON-OFF SEQUENCE switch) will
force all units to the OFF state, putting them
back in sync. This is the only way to re-sync
units other than disconnecting AC power to all
units. Remember: turning any key lock switch
to OFF does not affect the stored state, even
though it will temporarily turn the output of that
unit off. If it is turned back to REM, the PS-PRO
II will sequence back to ON because the stored
state is still ON.
MULTIPLE UNITS
you can use more than one PS-PRO II to handle
loads that exceed 20 amps (16 amps PRO-E). To
control them remotely with one or more remote
switches, connect (in parallel) the REM, +12V
(and optionally GND) terminals of all units. Be
sure that the mode (momentary or maintained) of
all units is set the same. Set all key lock switches
to REM. Connect a single maintained switch or
one or more momentary switches to the nearest
PS-PRO II, as discussed in the sections above.
To avoid tripping house breakers, the power
input for each PS-PRO II should come from a
separate 20 amp AC circuit. If you are unsure
whether your building’s wiring can accommodate
multiple fully-loaded PS-PRO II’s or PS-PRO
IIE’s, consult a qualified electrician.
STATUS TERMINAL
The STATUS terminal is an output that may be
used to illuminate an LED at the remote location
indicating that the power is available at the PS-
PRO II’s outlets. If it is high (+5V), the unit is ON
(or at least in the process of sequencing ON); if
low, the unit is OFF (or sequencing OFF). Simply
connect the indicator LED between STATUS
and ground (do not use a series resistor). If the
LED does not light when the switch is in the ON
position, check the polarity and reverse the LED
leads if needed.
If multiple PS-PRO II’s are controlled by one
or more momentary remote switches, all of the
PS-PRO II’s will change state (from on to off or
vice versa) on each rising edge of the voltage
on the REM IN terminal. All remote switches or
START ON-OFF SEQUENCE pushbuttons on
any unit’s front panel will toggle all of the units.
