Integra has introduced the DTR-6.4, a 6x100 Watt home theater receiver. It includes THX Select certification, DVD-A and SACD bass management, video conversion and switching capabilities, and an array of multi-room options, including powered Zone 2 and A-Bus. The Integra DTR-6.4 features 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 192 kHz/24-bit DAC found on each channel is combined with Integra's VLSC (Vector Linear Shaping Circuitry), previously found on the company's DVD players, to smooth the analog output, generating cleaner and more detailed audio reproduction, according to Integra.

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 with most multichannel speaker systems. 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. The subwoofer crossover is selectable at 40, 60, 80, 100, 120, or 150 Hz for optimal integration with almost any speaker arrangement. This feature can also be bypassed with Integra's Pure Audio Mode for the analog signal fidelity with full-range speakers.

The DTR-6.4 multizone receiver is capable of processing two sources simultaneously, or sending the same signal to both the main zone and systems in other rooms. It includes a built-in port for the flexible A-Bus audio distribution system favored by many installers, and also features both fixed and variable line level zone 2 outputs to feed second zone receivers or amplifiers. There is even Integra's Powered Zone 2 feature, which dedicates two of the receiver's internal amplifier channels to directly power speakers in a second room.

For integration with video equipment, the Integra DTR-6.4 features five A/V inputs and three outputs, each with both Composite and S-Video connections, and two assignable Component Video inputs. The receiver features Composite to S-Video conversion using a 3-line digital comb filter for superior reproduction, and all video inputs are up converted to 480i component video to simplify connection to displays. For HDTV and DVD video fidelity, component video switching has a 50 MHz bandwidth to prevent signal degradation. The DTR-6.4's AM/FM tuner section has 30 random presets, including direct access tuning via IR and RS-232 control ports.

The Integra DTR-6.4 will be available in June at a suggested retail price of $1,000.
