Pro Audio Sharpens Multiroom Focus

Atlanta - Pro Audio Technology plans to expand its selection of products targeted for use in multiroom-audio systems here at the Expo.

The company recently changed its name from Professional Home Cinema to reflect its growing focus on multiroom applications.

The company previously focused on large floorstanding and shelf-mount speakers designed for placement behind acoustically transparent screens and stretched fabric walls. The company's focus also included two bezel-less in-wall speakers and an in-wall sub, all of which many dealers have used for home theater as well as multiroom installs, said sales and marketing VP Larry Reagan. All speakers are designed to be driven by DSP-equipped amplifiers that include digital crossover filters for PHC speakers, digital boundary compensation, and digital equalization.

New speakers appearing at the show include the bezel-less two-way SCRS-5iw in-wall speaker with integrated metal back-box. It's smaller than the current in-wall, featuring 5-inch woofer and 0.75-inch compression tweeter in a proprietary elliptical horn. It also adds integrated back box. Maximum output is 110dB. The speaker operates in bi-amp or single-amp mode.

Also new is the company's first in-ceiling speaker with an angled baffle to deliver sound to the listener's seating position in a home theater, but it can also be used for multiroom audio, Reagan said. The bezel-less SCRS-25iw LCR speaker features fixed-angle baffle with two 5-inch woofers and the 0.75-inch compression tweeter and horn. The speaker is shallow enough to fit in a 2x6 stud bay for in-wall installation.

A new compact 12-inch in-wall sub is designed to fit in a 2x4 stud bay cavity and finishes off with the same designer friendly bezel-less grille design used on the in-wall speakers.

Also new is a compact in-room sub, the LFC-14sm, which features a long- throw 15-incg driver in a black paint or black ash wood veneer box. It's designed for in-room placement, whereas the company's other enclosed subwoofers are intended for placement behind a display screen.

Prices weren't available.

The company will also show production models of a previously announced PMA-series of modular programmable DSP amplifiers. They incorporate dealer-programmable DSP engine that includes digital crossover filters for all PHC speakers, digital boundary compensation, and digital equalization.

To deliver more channels of amp power in less space than the company's previous amp line, the PMA amps can be purchased with a variety of combinations of 200-, 500-, and 1000-watt amp modules up to four channels. The modules are inserted by the factory at a dealer's request into a common chassis along with DSP circuitry. The previous series required the use of a single amp-equipped chassis per channel.

In another change, the amp can be programmed by dealers to select specific crossover points for individual Pro speakers and equalize speaker response to correct for speaker placement behind screens and fabrics as well as placement near room boundaries. The previous amp series required the factory to come in to program some of these settings.

The amp also improves on its predecessor's equalization capabilities by using ultra-high resolution wide-band FIR (Finite Impulse Response) digital equalization.

The amp ships in quantity in the first quarter.
