Integra today said its two newest seven-channel AV receivers will be available this month. The company claims the 95-watt-per-channel DTR-30.6 ($1,000) and the 110-watt-per-channel DTR-40.6 ($1,300) are the first receivers designed to support the latest HDMI standard for 4K/60Hz video, as well as the latest HDCP2.2 copy protection standard. Integra also touts their ability to integrate with multi-room audio and home automation systems. The DTR-40.6 is THX Select2 Plus-certified and includes HDBaseT for wired connectivity up to 328 feet through a single CAT5e/6 cable.
Both feature seven HDMI inputs and two outputs, as well as a nice touch for vinylheads: a phono input. They can access streaming audio from Spotify, Pandora, SiriusXM Internet Radio, Tune In and others. They support “gapless playback” of high-def music files including WMA Lossless, FLAC, DSD, Double DSD, ALAC, Dolby True HD 24/96 and 24/192. The DTR-30.6 includes built-in Wi-Fi and Bluetooth to support wireless audio streaming.
Both receivers support 4K Ultra HD video displays, either via their 4K pass-through feature or by upscaling HD. Their InstaPrevue feature allows you to monitor multiple program sources.
Tech language from the press release:
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.
You’ll want to engage a custom installation or high-end audio/video professional to get the most out of these machines.
