The DTR-6.4 is a powerful 6x100 Watt THX Select home theater receiver which features advanced digital DVD-A and SACD bass management, sophisticated video conversion and switching capabilities, and an impressive array of multi-room and integration options, including powered Zone 2, A-BUS, and rear IR and RS-232 inputs.

It features powerful 32-bit Dual-DSP audio processing for THX Surround EX, Dolby Digital EX and ProLogic II, DTS-ES, Neo:6, and the new DTS-96/24 format. The high quality 192 kHz/24-bit DAC found on each channel is combined with Integra's VLSC (Vector Linear Shaping Circuitry), previously found only on our high-end DVD players, to smooth the analog output, generating cleaner and more detailed audio reproduction..

The DTR-6.4's 5.1-channel analog input includes optional bass management, a feature that is critical when listening to high resolution DVD-A and SACDs. The incoming signals are digitized and then processed by the receiver's DSP to route low frequency information to a subwoofer while excluding it from small satellite speakers that are ill equipped to handle deep bass..

It performs composite to S-Video conversion using a 3-line digital comb filter for superior reproduction, and all video inputs are upconverted to 480i Component video to simplify connection to displays. Both component inputs are HD-ready, passing HD signals without distortion.
