Furman Sound Power Conditioners Protect New Grace Church AV Installation

Furman Sound Power Conditioners Protect New Grace Church AV Installation

Dec 1, 2005 8:00 AM

Grace Church, a large non-denominational house of worship serving the Twin Cities metropolitan area of Minnesota, has completed an upgrade of its audio/video system. Performed by Audio Logic Systems of Bloomington, Minn., the installation included the purchase of six new PL-8 Pro Series II 20-amp power conditioners from Furman Sound, plus the reinstallation of an HDS-16 headphone/audio distribution system and eight accompanying HRM-16 headphone/audio remote mixers for a new Yamaha PM1D monitor desk.

The three-week project involved completely upgrading the FOH system, installing a modern replacement, and adding a monitor desk to the system. “Grace Church needed cost-effective, reliable power conditioners that would protect their Yamaha PM1D, DM2000, and [Audio-Technica] AT5000 series wireless system without creating any audio hums,” says Jason Kartak, who led the installation. “Furman Sound has a great reputation for reliability and cost-effectiveness, which is why we chose them over other manufacturers for this project.”

“Voltage irregularities are so commonplace in AC power, it’s likely that sooner or later, without protection, they would have damaged Grace Church’s sensitive, expensive electronics,” says Dave Keller, executive vice president of Furman. “In addition, electrical noise would be an obstacle to achieving the level of performance they paid for. Our PL-8 II conditioners filter the noise and provide excellent protection against bad power, while our HDS-16/HRM-16 system will give Grace Church great flexibility in creating custom audio mixes from multiple mics.”

Furman’s PL-8 Series II power conditioner features proprietary Series Multi-Stage Protection Plus (SMP+) technology, which combines three filtering and protection circuits: Linear Filtering Technology (LiFT) to suppress noise dramatically and consistently across the entire dynamic range, Series Multi-Stage Protection (SMP) to clamp and dissipate damaging transient voltages without sacrificing itself, and Extreme Voltage Shutdown (EVS) to protect against accidental connections to 208VAC or 240VAC. It has eight outlets on the rear panel, an additional outlet on the front panel, retractable LED rack lights, and a BNC connector that accepts any standard 12V gooseneck lamp. It is protected by a limited three-year warranty covering defects in materials and workmanship.

The HDS-16/HRM-16 distribution system cleanly routes eight mono and four stereo signals to remote mixing locations via Centronics 50-pin cables. Up to eight HRM-16 remote mixers can be connected directly or daisy-chained to a single HDS-16, allowing as many as 16 users to customize eight different mixes. A unique talkback system allows each user to communicate with other users and the main mixing location, and a SOLO system allows the engineer to mute all but one stereo send from the mix location for reviewing recent takes or rough mixes. The 2RU HDS-16 provides power and signal conditioning to the HRM-16 units, which also feature local effects send/return, line out, overall bass/treble controls, talkback level, and a master level control.
