(3)If none of the LED’s on the voltmeter are lit, and the Extreme Voltages LED indicator is illuminated, then the PL-Plus II has shut down power to its outlets because the input voltage is in a range considered extreme (in excess of 135 volts - 260 volts E version, 120 volts J version).

Digital Voltmeter:

(PL-Plus D II and PM-8 II only) Furman’s laboratory precision AC digital voltmeter continually measures incoming voltages, within a typical tolerance of +/- 1.5VAC. It should be noted that the voltage reading is incoming. No adjustment should be necessary on these units.

Digital Current Meter: (PM-8 II only) Furman’s laboratory precision AC digital current meter continually measures the total circuit AC load, within a typical tolerance of +/- 0.5 amp. Because these meters feature true R.M.S. technology, the current readings are accurate regardless of load conditions (capacitive, inductive or resistive).

NOTE: The PL-8 II, PL-Plus II, PL-Plus D II, and PM-8 II do not compensate for 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 may benefit from the use of one of Furman’s AC Line Voltage Regulators.

On/Off Rocker Switch:

This 15 amp capacity power switch is specifically designed to stand up to the enormous high inrush current demands of many Power Amplifiers.

Additionally, the semi-transparent rocker lights when switched to the “ON” position.

Extreme Voltage Shutdown 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.

E version: over voltage shut down is 260 VAC

J version: over voltage shut down is 125 VAC Guards against open neutral and accidental connection to 300+ VAC

Protection OK Indicator:

Although the Furman SMP circuit assures virtually free 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

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.
