Retractable Rack Lights, Rear Panel Lamp and Dimmer Control:

The PL-8 II, PL-Plus, and PL-Plus D II utilize 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.

All Series II 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. The Series II’s front panel LED lamps must be replaced by qualified Furman service personnel.

Multi-Segment LED voltmeter:

(PL-Plus II only)

This three-color, 20-LED bargraph is an accurate, self checking AC voltmeter that continually measures normal voltages. The meter reads from 90 to 128 volts in 2 volt increments (PL-PLUS E II: 180 to 256 volts, in 4 volt increments). The normal range voltages are indicated in green, with moderate and extremely high or low voltages in yellow and red respectively. The voltmeter provides three special flashing patterns to indicate abnormal conditions.

(1)If only the single leftmost (beneath the 90V mark – 180V for E version) LED flashes, the input voltage is marginally low.

(2)If all of the LED’s on the voltmeter flash, the input voltage is marginally high. Power to the PL-Plus’s outlets will remain unless the incoming voltage rises above the Extreme Voltage

PL-PLUS II, PL-PLUS D II, PM-8 II, PL-8 II specifications

Furman Sound is a renowned brand in the audio equipment industry, known for producing high-quality power management solutions essential for sound reinforcement and protection of sensitive electronic gear. Among their popular products are the PL-8 II, PM-8 II, PL-PLUS D II, and PL-PLUS II power conditioners, each offering unique features and technologies that cater to the diverse needs of audio professionals.

The Furman PL-8 II is a rack-mountable power conditioner designed to provide AC power filtering and protection. It features eight outlets, including one that allows for the connection of another device or daisy-chaining more equipment. One of its standout features is the Linear Filtering Technology (LFT), which significantly reduces noise that could adversely affect audio performance. Additionally, the PL-8 II has a built-in voltmeter and ammeter that provide real-time voltage and current readings, ensuring users are aware of their power consumption and equipment status.

The PM-8 II is another excellent choice for those requiring reliable power management. This model also includes several outlets and incorporates advanced surge protection to safeguard valuable equipment from harmful voltage spikes. It utilizes Furman’s proprietary technology to ensure that connected devices receive clean and consistent power, which is crucial for maintaining audio fidelity. The PM-8 II's sturdy metal chassis guarantees durability, making it suitable for both studio and live settings.

Moving on to the PL-PLUS D II, this versatile power conditioner goes beyond basic power management by offering digital readouts for voltage and amperage. This feature allows audio engineers to monitor power conditions more closely. Like its counterparts, the PL-PLUS D II employs LFT to improve audio quality by minimizing electromagnetic interference (EMI) and radio frequency interference (RFI). It also includes a retractable LED light, which is a practical addition for users working in low-light environments.

The PL-PLUS II takes power management to the next level, featuring a robust set of capabilities designed for the most discerning professionals. This model incorporates both LFT and automatic voltage regulation (AVR), ensuring stable power even in fluctuating conditions. The PL-PLUS II also comes equipped with an advanced surge protection system that includes an LED indicator, allowing users to see when the device is actively protecting against surges. Its durable construction and thoughtful design make it a top choice for anyone serious about their audio setup.

In conclusion, the Furman Sound PL-8 II, PM-8 II, PL-PLUS D II, and PL-PLUS II all offer advanced features and technologies that enhance audio performance and equipment safety. Whether for live sound applications or studio use, these power conditioners are essential tools for ensuring clean and reliable power delivery, enabling audio professionals to focus on what they do best.
