Retractable Rack Lights, Rear Panel Lamp and Dimmer Control:

The PL-8 Pro II utilizes a dimmer control for the two retractable front panel light tubes. The dimmer knob controls the brightness of both light fixtures. Turn it clockwise to increase brightness; turn it counterclockwise to decrease brightness. When the lights are not in use, we recommend turning the dimmer fully counterclockwise to maximize the life

of the LED’s, however, this is not absolutely necessary. Whether the light tubes are retracted or flush with the front panel, there will be no appreciable heat regardless of dimmer setting due to the efficiency of our full light spectrum LED’s. The Series II’s front panel LED lamps must be replaced by qualified Furman service personnel.

Both units feature a rear rack BNC socket which will accept any 12 VAC (0.5A) gooseneck lamp assembly, (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.

On/Off Circuit Breaker:

This 20 amp capacity magnetic circuit breaker switch is specifically designed to stand up to the enormous high inrush current demands of many Power Amplifiers. Additionally, the switch is shielded from accidental power disconnection with a hinged cover.

Extreme Voltage Shutdown (EVS) Indicator: This LED is normally off. It monitors a hazard common in the entertainment industry: 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+ circuit 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 voltage and subsequently that voltage exceeds 135V, it will shut off power to the outlet and the Extreme Voltage LED will light.

NOTE: The P8-Pro II and PL-8 Pro II do not compensate for extremely high or low line voltage. If you frequently move your rack to different locations, derive power from generators, use long extension cords, travel internationally, or are in an area prone to brownouts, you should use of one of Furman’s AC Line Voltage Regulators.

Protection OK Indicator:

Although the Furman SMP+ circuit assures virtually 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 remove 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.
