TO HOME THEATER EXCELLENCE

Company's Amplifiers & Surround Sound Processors Benefit from ADA's

Extensive Background in Customized Multi-room/multi-source System Design

ADA was one of the first high-end audio manufacturers to develop components for home theater use. As early as 1988, when Dolby Pro Logic surround sound decoding was still in its formative stages, the engineers at ADA realized that reliably delivering power to each of the new format's 5 channels was going to be a significant variable in creating a

credible and engaging home theater experience. Having successfully introduced System 56, one of the world's first multi-room/multi-source systems capable of routing a crisp, full-range signal from six different audio components to as many as 30 separate zones—or rooms—ADA was well positioned to make the most of the multi-channel promise of Dolby Pro Logic.

Instead of simply configuring three of their highly acclaimed stereo power amplifiers, ADA's first home theater breakthrough, in 1990, was their MPA-6, a multi-channel amplifier featuring six independent channels of amplification on a single fan-cooled chassis. Also offering built-in parametric bass EQ, the MPA-6 was the world's first multi-channel surround sound amplifier designed for home use.

Introduced in 1990, ADA's SSD-66 was specifically designed to complement the performance of the MPA-6. This precision-crafted Dolby Pro Logic surround sound processor/preamplifier remains a vital part of ADA's home theater offering, thanks to modular software and hardware upgrades that have added THX, Dolby Digital (AC-3) and DTS (Digital Theater Systems) decoding options. In fact, ADA was one of the world's first manufacturers to begin shipping Dolby Digital (AC-3) and DTS decoders

(in 1994 and 1995, respectively).

In 1992, ADA dramatically expanded its position in home theater with the

introduction of the MPA-500, a massive dual-chassis power amplifier capable of delivering an unprecedented 450-watts into each of its five channels, at 4-ohms. The

MPA-500 is still regarded as the most powerful multi-channel THX-certified power amplifier ever built. ADA also offers two other multi-channel power amplifiers ideally suited to a variety of home theater installations. The PTM-650 is just under two inches high, and yet it generates 85-watts into each of its six channels, at 4-ohms, while the PTM-6150 is a six-channel power amplifier rated to cleanly handle up to 250-watts per channel, at 4-ohms.

The latest jewel in ADA's home theater crown is the immaculate Cinema Reference surround sound processor/preamplifier. Introduced in the fall of 1997, the Cinema Reference is the first home theater component to offer complete THX enhancements in Dolby Pro Logic, Dolby Digital and DTS modes. It truly represents the absolute state of the home theater art and has already garnered numerous rave reviews.

The single most distinguishing factor running throughout all ADA home theater components is their use of the company's ADA Bus. This innovative bi-directional serial-data communication system provides a modular and convenient way to upgrade to new and emerging technologies while making it easy to interface with a variety of external controllers, switchers and other custom-configured components.

Borrowing a page from their custom installation background, all ADA power amps may be activated from a low voltage trigger signal from the controlling preamplifier or processor, making it much easier to create a complete, centrally controlled home theater system. All ADA home theater components are available for standard rack-mounting or in free-standing component cabinets.

Quality control is extremely stringent throughout the entire ADA organization. Not only are all ADA products hand-crafted in the United States, the company also creates each chassis in-house to the most exacting tooling standards. Quality Control Supervisor Charles Revy notes, "We fully test each and every system we make. It's this

comprehensive testing procedure that permits us to quote a near-zero product failure rate."
