Integra has introduced a pair of new home theater audio/video control receivers, featuring A-Bus multi-room capability and built-in 2-zone control. Both will be available from Integra dealers this month.
The higher-end model is the DTR-6.4 ($1,000 US), a 6 x 100 Watt THX Select certified receiver that features selectable bass management for the DVD-A/SACD 5.1 analog inputs. The mid-price model is the DTR-5.4 ($600 US), offering most of the same features as the DTR-6.4 in a 6 x 85 Watt package, without the multichannel-in bass management.
The Integra DTR-6.4 provides advanced bass management features for multichannel 5.1 analog inputs (DVD-Audio and SACD)
The Integra DTR-6.4 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 on the company’s 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 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 any speaker arrangement. This feature can also be bypassed with Integra’s exclusive Pure Audio Mode for the ultimate in analog signal fidelity with full-range speakers.
Designed to offer maximum flexibility and integration options for whole-house audio distribution and control, 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 upconverted to 480i Component video to simplify connection to displays. For HDTV and DVD video fidelity, component video switching boasts a 50 MHz bandwidth to prevent signal degradation.
The DTR-5.4 features the same 32-bit dual DSP processing, broad support for the full range of multichannel decoding formats, and the Vector Linear Shaping Circuitry (VLSC) of its more-expensive sibling. It provides inputs for five A/V sources and two audio-only sources, including four assignable digital inputs, and one digital output. One A/V input, including optical digital jack and S-Video, is located on the front panel for easy connection of a camcorder or portable MP3 player. There are two assignable component video inputs and one output, with a component video switching bandwidth of 50 MHz to prevent degradation of HDTV and progressive scan DVD signals.
The Integra DTR-5.4 shares the sophisticated DSP audio processing circuitry of the more expensive DTR-6.4
The DTR-5.4’s six internal power amplifier channels deliver a continuous power output of 85 Watts per channel into 8-ohm loads, and 110 Watts into 6 ohms. It boasts a linear frequency response range of 10 Hz – 100 Hz, thanks to Integra’s Wide Range Amplifier Technology (WRAT). The inclusion of a new, more massive High Current Power Supply (HCPS) transformer, combined with high-capacity filter capacitors, gives the receiver tremendous current reserves for audio transients and instantaneous power on demand.
As a versatile two source multizone receiver, the DTR-5.4 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. In addition, with Integra’s Powered Zone 2 feature, two of the receiver’s internal amplifier channels can be dedicated to powering a second room, eliminating the need for any additional electronics components.
The DTR-5.4 also features two programmable 12-Volt trigger outputs for the main zone, an additional 12V trigger output for the second zone, IR control input and output jacks, and an RS-232 port to integrate the receiver with whole-home control systems and touchscreens.
Both new Integra receivers include a high quality AM/FM tuner section with 30 random presets, including direct access tuning via IR and RS-232 control ports. The included backlit preprogrammed/learning remote control makes system integration and control simple and convenient.
