Amplifiers. Additionally, the semi-transparent
rocker lights when switched to the "ON" posi-
tion. (E-versions feature 10 amp capacity)
extreme Voltage shutdown Indicator:
This LED is normally off. It monitors a
hazard common in the entertainment indus-
try: wiring faults – for example, accidental
connection to 220VAC where 120VAC is
expected, or an open neutral from a 208
or 240VAC feed. The Series II SMP+ cir-
cuit senses voltages that are so high that
operation would be impossible and shuts
the power down before damage can occur.
upon initially applying power to these units,
the Extreme Voltage indicator LED will light
if the input voltage is above the extreme
voltage cutoff, and power will not be applied
to the unit's outlets. If the unit has been
operating with an acceptable input volt-
age and subsequently that voltage exceeds
135V, it will shut off power to the outlet and
the Extreme Voltage LED will light. (E ver-
sion: over voltage shut down is 260 VAC and
guards against open neutral and accidental
connection to 300+ VAC)
protection oK Indicator:
Although the Furman SMP+ circuit assures
protection from transient voltage spikes and
surges, nature has a way of occasionally
creating electrical forces that are beyond the
capabilities of any TVSS device to absorb
without some degree of damage. In the
rare instance that this occurs, the green
"Protection OK" lED indicator located on
your front panel will dim. If this happens,
some level of protection from voltage surges
will remain, but the Furman's clamping
voltage rating will be compromised. The unit
must be returned to Furman Sound, or an
authorized Furman service center for repair.
NOTE: If the mains power is above the high
cutoff voltage and has caused the unit to re-
move power from its outlets, it cannot restore
power without the operator manually turning the
unit off, then on again. Avoid turning the unit
back on, without first checking the source of the
problem, and perhaps changing the AC source.
All Series II units feature a rear rack BNC
socket which will accept any 12 VAC (0.5A)
gooseneck lamp assembly, (such as the Fur-
man 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. The Series II's front
panel lED lamps must be replaced by qualified
Furman service personnel.

(PS-8R II & PS-8R II E)
In the most basic configuration, only two wires
and an SPST switch are needed to initiate remote
ON or OFF sequence. The switch may be either
a momentary or maintained-contact type. If a
third & fourth wire are used, an LED may also be
installed at the remote end to indicate that the
power is on.
MAINTAINED VS. MOMENTARy
CONTACT SWITCHING
Maintained switches, such as most toggle
switches and push-on/push-off switches (including
the Furman RS-1), stay open until switched and
then remain closed until switched again.
Momentary switches, usually pushbutton types
like the Furman RS-2, are normally open and stay
closed only as long as the button is pressed. An
on-off switch of either kind may be used to actuate
the PS-8R II's remote operation.
