SMP Surge Protection Furman’s exclusive Series

Multistage Protection (SMP) Technology prevents

equipment down-time by monitoring and quickly reacting

to extreme line voltage conditions.

LiFT filtration – Uses a finely tuned low-pass filter to reduce

differential AC noise. LiFT is remarkable in its ability to

linearly filter AC noise such that the attenuation curve is

continuous over a wide bandwidth.

Remote Legacy style interface with Phoenix type

connector allows remote operation and compatibility with

Furman legacy equipment.

Rear Panel Lighting BNC connector for gooseneck lamps

Multi-Color LED Indicators provide status at a glance.

9 Outlets IEC-C13; 1 front / 8 in rear panel

2.5M Power Cord – IEC-C13 to CEE-7/7, (IEC Strain

Thank you and congratulations on your purchase of your

Furman PS-8RE III Surge Protector / Power Sequencer

with Furman’s exclusive SMP+ Technology. No other 10

Amp Surge Protector / Power Sequencer offers a better

combination of value and performance. Furman has de-

signed the PS-8RE III to provide many years of reliable

service. Please take a moment to read this manual and

learn about the many features and benefits that the PS-

8RE III has to offer.

1. Please read and follow all instructions.

2. Please keep these instructions.

3. Please heed all warnings.

4. WARNING: This device is intended for indoor use only.

Do not use this device in or near water. To reduce the risk

of fire or electric shock, do not expose this device to rain

or moisture.

5. CAUTION: To reduce risk of shock, please disconnect

the PS-8RE III from AC power before servicing any equip-

ment connected to the PS-8RE III.

6. Clean only with dry cloth.

7. CAUTION: Do not install near any heat sources such

as radiators, heat registers, stoves, or other equipment

that may produce extreme heat.

8. Protect power cords from being walked on or pinched,

particularly at plugs and convenience outlets.

9. Please, only use accessories specified by the manu-

facturer.

10. Refer all servicing to qualified personnel. Servicing is

required when the unit has been damaged in anyway or

fails to operate.

11. WARNING: Do not use power cord as the main

power disconnect. The device is intended for AC power

sequencing.

12. Do not defeat the safety purpose of the Schuko plug.

A Schuko plug has two pins and a grounding contact or

receptacle. If the Schuko plug does not fit into your outlet,

please consult an electrician for assistance

13. This device is supplied with an IEC-C13 to CEE-7/7

Schuko plug. Any prospective replacement cord must

comply with the minimum ratings of the line cord originally

supplied with this device and be HAR Certified for use in

the country in which the unit is deployed.

14. WARNING: This device must be connected to an AC

outlet with a protective earth ground connection

AV equipment is most vulnerable and susceptible to dam-

age during those first few milliseconds after the power is

turned on or off.

When audio amplifiers are powered on, a large inrush

current occurs as the large capacitors in the power supply

charge. This inrush can be on the order of several hundred

amps for a number of AC cycles. If more than one amplifier

is connected to a single branch circuit, the inrush current

is multiplied and can cause the circuit breaker to trip, or

the line voltage to sag. Additionally, if the amplifier is pow-

ered on either before or concurrent with signal processing

equipment, the result can be a dreaded speaker “pop”. This

all-too familiar noise occurs as transients from the signal

processing equipment flow uncontrolled to the inputs of

the power amplifier. The amplifier amplifies this signal

and passes the transient “pop” along to the speakers. The

result can be catastrophic to both speaker and amplifier.

Powering down A/V is equally as perilous. Unlike other

A/V equipment, the large capacitors found in amplifiers

will store their charge. This means if signal processing

devices and amplifiers are switched off simultaneously,

the amplifiers are still operational as the signal processing

equipment is switched off. Just as with startup, the power

down phase can cause equipment to emit transients which

are amplified by the amplifier, then propagated to the

speakers and “pop”!

AC Power sequencing addresses these problems by pow-

ering up your equipment in stages. The signal processing

equipment is powered on first and allowed to stabilize, and

then the amplifiers are powered on.

The first stage signal processing equipment may still emit

transient noise upon power up, but because the amplifiers

have yet to power on, the transient signal passes without

incident. Power sequencing stages the activation of

heavy loads, which prevents nuisance breaker trips and

equipment damage due to line sags and brown-outs. This

means that inrush currents are offset in time, rather than

occurring simultaneously. This can also be advantageous

to upstream equipment if the sequencer is supplement-

ing other power management such as a UPS or voltage

regulator.

The Furman PS-8RE III provides three delay stages. If

three stages of power sequencing are not enough for your

application, you can chain together multiple PS-8RE III

sequencers. For best results we recommend that your

power amplifiers always receive power last. Plug the am-

plifiers into DELAY 3, or divide them into two groups and

plug one group into DELAY 2, and the other into DELAY

3. The low level equipment feeding the amps, such as

mixers and signal processors, should plug into DELAY 1

such that they will turn on and stabilize first.

The turn-on delay intervals are factory preset to 5 seconds

per stage. This delay can be increased or decreased us-

ing the rear panel trim pot adjustment (see “Adjusting the

Delay Interval” for details).

In the event of a power outage, all equipment plugged

into the PS-8RE III will lose power simultaneously. When

power is restored, the behavior of the PS-8RE III will

depend upon switch settings and how the unit has been

configured:

• If the PS-8RE III has been configured for Maintained

mode and the Sequence switch is in the ON position, the

delayed outlet groups will turn on in the normal delayed

sequence when power is restored.

• If the PS-8RE III has been configured for Momentary

mode the delay outlets will remain off until activated by

the end user.

Sequenced Outlets

SMP+ (Series Multi-Stage Protection Plus)

Unique to Furman’s SMP+ is its unparalleled clamping volt-

age. While other designs offer clamping voltages that are

well above 660 Vpeak, the SMP+ clamps at 376 Vpeak,

(266 VAC RMS). This unprecedented level of protection

is ONLY available with Furman’s SMP+ technology. Fur-

man’s trusted over-voltage circuitry protects against all

too frequent accidental connections to 408 or 440 VAC by

quickly disconnecting the loads from the incoming power

until the over voltage condition has been corrected.

Furman’s SMP+ surge suppression virtually eliminates

service calls. Traditional surge suppression circuits “sac-

rifice” themselves when exposed to multiple transient

voltage spikes, requiring the dismantling of your system,

and repair of your surge suppressor. With Furman’s

SMP+, however, damaging transient voltages are safely

absorbed, clamped, and dissipated.
