Integra Research RDC-7 Introduction

Few people understand the structure of Onkyo and their related companies. Onkyo Corporation, located in Osaka Japan , has two other divisions, each with more refined products that meet the performance expectations of Audiophiles. These two divisions include Integra and Integra Research. Many confuse Integra and Integra Research as being one in the same, but that's not the case. Integra Research is the newest division of Onkyo that specializes in high-end audio products. Since their inception, they have introduced three home theater components which were jointly developed with several US companies. The line-up consists of the Integra Research RDC-7, a 7.1-channel THX Surround EXT audio/video preamplifier/processor; the RDA-7, a US-designed and manufactured seven-channel THX power amplifier with each channel rated at 150 Watts; and the RDV-1, a premium DVD player with a broadcast-quality video section. All three models are THX Ultra® certified. The A/V processor and DVD player are IEEE-1394 capable, and the processor's operating system and surround formats are upgradeable via software that can be uploaded from a PC. The RDC-7 processor's electronics have also been modularized for future hardware upgrades. This ensures that these products will not be rendered obsolete by the introduction of new surround formats.

The three Integra Research Home Theater components were jointly developed in partnership with two U.S. audio and video technology firms: Apogee Electronics Corp., Balanced Audio Technology. Integra Research also worked closely with a team of custom installers to ensure their products meet the needs of that customer base.
