A virtual press conference from Sound & Video Contractor


Mechanicsburg, PA – April 2008… When it came time to replace an aging power amp at the Mechanicsburg Kingdom Hall of Jehovah’s Witnesses’ meeting facility, freelance sound designer and installer Greg Bressler faced a common, yet daunting challenge. He had precious little space in the equipment rack for the replacement unit, and yet he needed suitable power and clean sound quality capable of driving two distinctly different loudspeaker systems. After examining several models from a variety of equipment manufacturers, he selected the Avlex PA-200 power amp—distributed in North America by Kansas City, MO-based Avlex Corporation.

While discussing some available options with Paul Moyer, salesman at Moyer Electronic Supply of Pottsville, PA (the authorized Avlex dealer in the area), Moyer suggested Bressler take a close look at the Avlex PA-200. “The Avlex PA-200 is a contractor grade power amp that delivers generous amounts of power and has a very compact form factor,? states Moyer. “We’ve had tremendous success with this model and, upon hearing Greg’s concerns, I suggested this amp may very well be the solution.? As it turns out, Moyer’s suggestion was spot on for this particular project.

The meeting hall at the Mechanicsburg Kingdom Hall of Jehovah’s Witnesses is approximately 46 feet wide by 53 feet deep and has fixed seating. According to Bressler, “In this particular space, the power amp drives the entire facility. The PA-200 is configured so that channel 1 powers two loudspeaker clusters—each consisting of two Bose MM-102 loudspeakers. The clusters are suspended in the center of the space, with the first cluster over the stage area at the front, and the second cluster positioned approximately 14 feet into the room. This part of the system is operating at 4 ohms, and the PA-200’s power rating of 200 watts per channel is just perfect for this size area.?

“The amp’s second channel drives a 70-volt distributed sound system through a line balancing transformer,? continued Bressler. “This second channel powers all secondary areas including the lobby and restrooms. In these areas, ceiling loudspeakers are utilized.?

When queried about those aspects of the PA-200 that made it the right choice for this particular project, Bressler offered the following assessment. “I listened to several different power amps,? said Bressler, “and I honestly found the PA-200 to have cleaner and more evenly distributed power throughout the entire frequency range—not only for dialog, but particularly so for music. With music reproduction, the PA-200 delivers clear, crisp performance across the entire frequency spectrum. This wasn’t the case with other models I auditioned. Of equal importance, rack space was extremely limited. The PA-200’s 1RU size was just what we needed and, unlike many other power amps, the depth of the unit is quite modest, so the amp doesn’t protrude out of the back of the equipment rack.?

Addressing technical questions can be a challenge for the most qualified of sales professionals. When Bressler had questions, Paul Moyer was ready—with a little help from Avlex Corporation’s technical support group. “I get a lot of questions about the gear we sell,? said Moyer, “and it’s impossible to have every answer. Whenever I’ve called Avlex, I’ve received prompt, courteous support, and this is really important when you have a customer waiting. Their support services are second to none, and it’s precisely this type of service that enables us to provide our customers with accurate information.?

With their new Avlex PA-200 power amp up and running, Bressler reports that his client is extremely pleased. “Everyone has been very complimentary about the system’s performance,? states Bressler. “I believe Avlex has a real winner on its hands with this amp. I’ve been equally impressed with the MIPRO wireless system (also distributed by Avlex) I installed there. They have a MIPRO ACT 707F receiver frame stocked with 4 ACT 707MC receiver modules and ACT 707HM handheld transmitters. The system delivers clear, dependable performance. For the money, I believe the products we get through Avlex represent tremendous bang for the buck.?
