SERIES II 15 AMP Power ConditionerS

I N T R O D U C T I O N

Thank you for purchasing a Furman Series II Power Conditioner, and congratulations on your choice. The Series II power conditioners feature Furman’s revolutionary Series Multi- Stage Protection Plus (SMP+) circuit, as well as our exclusive Linear Filtering Technology (LiFT). Together, these technologies comprise what is, without question, the world’s most advanced and comprehensive transient voltage surge suppressor / conditioner.

SMP+ (Series Multi-Stage Protection Plus)

Furman’s SMP+ surge suppression virtually eliminates service calls. Traditional surge suppression circuits “sacrifice” themselves when exposed to multiple transient voltage spikes, requiring the dismantling of your system, and repair of your surge suppressor. Not so with SMP+. With Furman’s SMP+, damaging transient voltages are safely absorbed, clamped, and dissipated.

Unique to Furman’s SMP+ is its unparalleled clamping voltage. While other designs offer clamping voltages that are well above 330 Vpk, Furman’s SMP+ clamps at 188 Vpk, (133 VAC RMS) even when tested with multiple 6000 Vpk

-3000 amp surges! This unprecedented level of protection is only available with Furman’s SMP+ technology. Additionally, Furman’s

trusted over-voltage circuitry protects against all too frequent accidental connections to 208 or 240 VAC, by shutting off the incoming power until the over voltage condition is corrected. [For E versions: Furman’s SMP+ clamps at 376 VpK, (266 VAC RMS.)]

LiFT (Linear Filtering Technology)

Unfortunately, traditional AC filter - conditioners have been designed for unrealistic laboratory conditions. Prior technologies, whether multiple pole filter or conventional series mode, could actually harm audio and video performance more than they help, due to the resonant peaking of their antiquated, non-linear designs. Under certain conditions, these designs can actually add more than 10 dB of noise to the incoming AC line! Worse still, lost digital data, the need to re-boot digital pre-sets, or destroyed digital converters are frequently caused by excessive voltage spikes and AC noise contaminating the equipment ground. Furman’s SMP with LiFT takes another approach, ensuring optimal performance through linear filtering and no leakage to ground.

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.
