Phase Technology Introduces PT A-BUS Distributed Audio Systems

JACKSONVILLE, FL — September 10, 2004 — Phase Technology, American designer and manufacturer of home entertainment speakers, announced it has teamed up with A-BUS to offer the PT A-BUS multi-room audio distribution packages. Phase Technology offers its acclaimed in-wall speakers with A-BUS distribution technology to provide dealers with complete whole-house audio packages that give customers outstanding sound and intuitive system control. Phase Technology is debuted its PT A-BUS systems at CEDIA EXPO 2004 in Indianapolis.

“PT A-BUS is the custom installer’s solution for bringing remarkably clear and full sound to every room in the house,” said Roberta Lewis, vice president of sales and marketing at Phase Technology. “Pairing our performance-tested speakers with A-BUS’ industry-standard audio distribution architecture, PT A-BUS establishes a new quality watermark for multi-room audio systems. The sound quality is excellent, and users can control the music and sources very easily. PT A-BUS can put music in every room in the home, and with our in-wall speakers, installers can design a system that adapts to any decor.”

Phase Technology offers five PT-BUS components for integration with its elegant in-wall speakers to give dealers everything needed to tailor systems that give customers powerful audio performance and attractively match the surrounding decor. PT-BUS components are easy to install and make controlling sources simple for end-users. Phase Technology offers several components as part of its PT-BUS line including:

HUB-1 – Acts as the system’s “brain,” converting source audio signals for distribution via cat-5 cable in addition to providing power. Multiple hubs can be linked via a RJ-45 jack to expand sound distribution to the needed number of rooms. Auto signal-sensing or a 12 volt trigger can be used for on/off control. The HUB-1 features the following inputs: 1 RJ-45, 4 pair (L/R) RCA, 2.5mm DC power socket, local IR Xantech-compatible screw terminals, 2.1mm 12V 100-300mAmp, and outputs: 4 x RJ-45 to four rooms, 1 x RJ-45 (to additional HUB), 4 x 3.5mm sockets for IR, 12 volt trigger from local IR status terminal

AS-1 – Audio selector integrates four sources into the PT-BUS system. Outputs loop sources back to a receiver, such as at the main home theater system. The AS-1 includes the following inputs: 4 pair (L/R) RCA, and outputs: 4 x 3/5mm IR sockets, 1 x RJ-45 (to HUB), 4 pair (L/R) RCA, 12V trigger.

TP-1 – In-wall volume control with integrated A-BUS stereo power module. It features touch button (up and down) control and an infrared receiving window.

VC-1 – In-wall volume control with integrated A-BUS stereo power module. The VC-1 features a rotary volume control.

LM-1 – Local Input Module with stereo (L/R) RCA inputs for adding a source in any room. The LM-1 features automatic signal switching and 1 pair (L/R) RCA inputs.

LRC-1 – Learning Remote Control incorporates the functions of all the sources’ original remotes. It is programmed by entering manually entering product codes or simply by lining up the LRC-1’s IR window with another remote’s to initiate function transport.

RM-1 – Credit card-sized remote allows volume control and source selection when used with the AS-1 or any A-BUS equipped receiver, from any room.

The PT A-BUS System distinguishes itself from traditional audio distribution systems by placing local amplifiers in each room or zone, instead of using a central multi-channel amp. This avoids signal dissipation that can result from long speaker wire runs. PT A-BUS uses a single cat-5 wire to run source audio from the HUB-1 to the rooms’ power modules (integrated with volume controls). The signal is ultimately transmitted to speakers with a short wire run, which guarantees sound is robust and precisely balanced. Even speakers in the audio zones furthest from sources produce high-quality sound, and since less cable is required, installations are faster and more cost efficient.

PT A-BUS systems provide a customized and intuitive entertainment experience. Music can be distributed to every room in a home or office while giving each user the ability to control the sound in their room. Using the LRC-1 learning remote control, users can access source transport functions (play, pause, track skip, etc), and adjust the volume from any room via the TP-1’s IR-receiving window. The RM-1 credit card-sized remote controls volume and source selection, and is the perfect supplement for the kitchen, den, or patio. The LM-1 local input module allows a new source to be immediately enjoyed through a room’s speakers without disturbing the sound in other zones. Both TP-1 and VC-1 in-wall volume controls and the LM-1 come in white, ivory, and almond.
Phase Technology’s in-wall speakers seamlessly integrate with any interior and perfectly complement A-BUS technology in delivering high-fidelity sound that doesn’t intrude on decor. The Custom Installation and Contractor series speakers can be painted or wallpapered for a nearly invisible presence that puts all attention on the music. Each family produces dynamic and detailed sound and can even be used outdoors for outstanding performance on the front porch, back patio, or under eaves.

Phase Technology’s speaker lines incorporate many proprietary innovations like the soft-dome tweeter, the industry’s standard invented by Bill Hecht, founder of Phase Technology. Other patents cover the self-damping woofer voice coil, the manufacturing process for flat-piston midrange drivers and woofers, silicone-injected drivers for resonance damping, and the positive-clamping mounting system for the premier in-wall Model CI-110/II. The company also developed the Unicell Zero-Diffraction treatment that reduces acoustic reflections off cabinet and grille surfaces. Phase Technology manufactures its wood cabinets by hand and performs quality control tests at every step of the fabrication process.

Building on five decades of design and engineering innovation in the manufacture of high quality, yet affordable speakers, Phase Technology supports its products with a 10-year warranty on speakers, while amplifiers are backed by a 3-year warranty.
