Integra DRX-R1.1 Network AV Receiver with 4K HDBaseT support.

Higher-end custom-installation brand Integra this week announced new “Dot 1” series AV controllers and receivers, including the first such products with support for 4K HDBaseT wired distribution networks supporting 4K/60 fps/4:4:4/HDR10/Dolby Vision in runs of up to 100 meters over CAT 5/6/7 cable.

The Integra offerings include a network AV controller (model DRC-R1.1) and an 11.2-channel network AV receiver (DRX-R1.1) in the company’s reference-grade Research Series. The two products will be available through authorized custom home theater installers in March at suggested retail prices of $2,500 and $3,300, respectively.

Integra said the “Dot 1” series products are the first in their respective categories to incorporate 4K HDBaseT circuitry to relay some of the latest 4K UHD video and accompanying audio standards and protocols over common cables.

HD BaseT enables installers to run wired CAT 5/6/7 cables to send uncompressed Ultra-HD video (in up to 4K resolution) to a network of devices or as a point-to-point connection. The technology supports virtually all video sources, including legacy products, and will accurately render gaming graphics and features without diminishing audio or video quality.

Both the Integra DRC-R1.1 and DRX-R1.1 also support Dolby Atmos and DTS:X object-based audio surround sound formats with up to 7.2.4 channels; multi-zone processing; wireless technologies including Chromecast built-in with Google Assistant voice control and DTS Play-Fi multi-room hi-fi music streaming.

Both units incorporate what Integra calls “hand-selected components” for optimal sound reproduction.

Each model also includes 8 HDMI in (all but 1 front HDMI support features in the HDMI 2.0a spec), main out, and sub/Zone 2 out with support for HDCP 2.2, 4K/60 Hz, Dolby Vision, HDR 10, Hybrid Log-Gamma (HLG), Wide Color Gamut (WCG), extended (sYCC601, Adobe RGB, Adobe YYC601), and BT.2020 video pass-through. No mention was made of support for the new HDMI 2.1 supporting ICs. Those next-generation inputs still await testing and compliance specifications before manufactures can proceed with implementation.

The Integra DRC-R1.1 11.2-channel network A/V controller carries THX Certified Ultra designation. The unit is equipped with high-quality copper screws to lock modular circuitry blocks; a double-skinned insulated frame, internal bracing to enhance anti-resonant characteristics, floating circuit boards, multiple 32-bit DSPs and DACs, the company said.

The DRC-R1.1 processor supports 4K HDBaseT, object-based audio processing through 7.2.4 channels, and features gold-plated 11.2-channel balanced XLR audio pre-outs. Other features include three 32-bit SHARC DSPs, independent differential audio DACs for stereo front L/R (384 kHz/32-bit AK4490), surround (768 kHz/32-bit AK4458), and separate DACs for Zone 2 for HDMI IN 1-5, SPDIF (PCM), NET, and USB sources. Zone 3 support is added for NET and USB sources.

The controller also feattures a bi-directional IP and RS-232 port for advanced home automation control systems, two IR input/one output, and three programmable 12V trigger outputs with adjustable delay.

The DRX-R1.1 will be the new flagship of the Integra network AV receiver line. It carries THX Certified Select status and handles 140-Watts per channel (8 ohms, 20 Hz–20 kHz, 0.08% THD, 2 channels driven, FTC), the aforementioned 4K video support and multi-channel audio processing present in the DRC-R1.1. It also features similar high-quality component and rigid build characteristics, along with a custom shielded power supply and shielded amplification, to isolate signals from noise. The high-current amplifier design features custom-made magnetic-flux low-hum EI power transformer.
