Integra just introduced two home theater receivers, models DTR-30.6 and DTR-40.6. Both offer the latest HDMI version supporting 4K/60 Hz and HDCP 2.2 copy protection, multi-room capability, and 7 in/ 2 out HDMI configuration. The more expensive DTR-40.6 adds 15-watts more power per channel, THX Select2 Plus certification, bi-amping capability, HDBaseT connectivity, one extra multi zone output, and improved circuitry across all channels. Amplifier power is rated at 7×95-watts or 7×110-watts per channel each.
HDBaseT is the only technology that enables long-reach wired connectivity up to 328 feet (100 meters) for uncompressed full HD multimedia content, through a single CAT5e/6 cable, including 3D and 2K/4K Ultra HD making it ideal for the custom integration specialists. The HDBaseT and HDMI output ports on the DTR-40.6 can be assigned for either main or second zone configuration.
Networking features provide access to the widest selection of audio streaming content such as that from Spotify, Pandora, SiriusXM Internet Radio, Tune In and many others. The DTR-30.6 and DTR-40.6 also have a phono input and provide extensive support for legacy digital and analog sources. These are few of the receivers to support gapless playback of most every type of high definition music files including WMA Lossless, FLAC, DSD, Double DSD, ALAC, Dolby True HD 24/96 and 24/192 formats from HD music download services, USB or via local area network (LAN). Additionally, the DTR-30.6 includes both built-in Wi-Fi and Bluetooth to support wireless audio streaming from home network and mobile devices.
On the video side, both receivers provide full support for 4K Ultra HD video displays, using either the 4K pass-through feature or upscaling for conventional HD video sources via a Marvel QDEO processor. Both models also include ISF calibration capability, which allows ISF Certified calibration technicians to custom define both day and night settings for each individual video source component connected to the receivers. The incorporation of the ISF calibration function in theses receiver results in simpler system configurations, reduced set-up time, and end-user systems offering optimal video performance while retaining the ease-of-use of HDMI switching.
The Integra DTR-30.6 and DTR-40.6 include an array of very useful video features, including InstaPrevue, which allows users to monitor multiple program sources with this HDMI variant of picture-in-picture. There is also Mobile High-definition Link (MHL), which uses the front-panel HDMI port to deliver HD video and up to 7.1 channels of audio from compatible Android smart devices and other products.
Sound quality is a key factor in Integra’s design process. The custom amplifier section consists of hand-selected parts, high current, low impedance power supply section, and employs three-stage inverted Darlington circuitry and Wide Range Amplifier Technology (WRAT) — a low negative-feedback topology for low distortion and high dynamic range. The DTR-40.6 includes three-stage inverted Darlington Circuitry across all channels as well as the ability to drive difficult and demanding 4 ohm loads. Phase Matching Bass circuitry, introduced in the 2013 models, optimizes low frequencies while preserving mid-range clarity. It counters phase shifting — which can affect sound quality — by synchronizing the timing of different frequencies. The result is deep, well-defined bass that won’t overwhelm vocals or strings.
In addition to the 7.1 channel Dolby True HD and DTS-HD Master Audio both models incorporate Dolby Pro Logic IIz to provide alternate surround option for front height channels. Proprietary AccuEQ room calibration bypasses any filtering of the front L/R channels so the loudspeakers’ unique audio characteristics are preserved. The remaining channels are very quickly and easily optimized for balanced surround-sound performance.
Custom installers will appreciate the inclusion of Powered Zone 2 and Zone 2 preouts in both units, the addition of Zone 3 preout in the DTR-40.6, two IR inputs and one output for remote control integration, and three 12-volt triggers. A bi-directional RS-232 port and Ethernet jack are available for seamless control from home automation systems.
