Onkyo USA introduced this week three new 7.2-channel audio/video receivers in its premium RZ series, due to hit retail stores in June.

The new models are targeted at discerning home theater aficionados looking for a multifunctional network AV receiver that is easy to use and presents accurate and immersive music and sound.

The models include: the THX “Certified Select” TX-RZ820 ($1,399 suggested retail), pictured at top; the THX Certified Select TX-RZ720 ($1,099) and the TX-RZ620 ($899).

The receivers are distinguished primarily by power performance with the TX-RZ820 offering 130 W/Ch, the TX-RZ720 offering 110 W/Ch, and the TX-RZ620 offering 100 W/Ch., respectively. All power listings are at (8 Ohms, 2 channels driven, 20 Hz–20 kHz, 0.08% THD, FTC).

The two higher-end models are said to have earned THX Certified Select designation for their “low-distortion performance at Theater Reference Volume.”

The receivers feature Dynamic Audio Amplification that directs “high current through low impedance to accurately control large speaker drivers, responding instantaneously to rapid changes in massed, constantly moving audio waves.”

The receivers are said to produce a wide-spectrum reproduction range of 5 Hz–100 kHz to produce “high-energy in sound.”

The receivers have a 384 kHz/32-bit AK4458 digital-to-analog converter (DAC) with VLSC filtering technology which removes subtle digital noise.

All receivers include Dolby Atmos and DTS:X object-based audio decoding, and include AccuReflex phase-alignment of low- and high-directional sounds at the listening position when used with Dolby Atmos-enabled speakers.

All feature a front HDMI input for temporary device connection.

The TX-RZ620 adds an HDMI Sub Output to connect a second TV or projector, while TX-RZ720 and TX-RZ820 feature a Zone 2 HDMI output.

All models support dual-band Wi-Fi (5 GHz/2.4 GHz), and include support for a host of popular music streaming services including: Pandora, TIDAL, Spotify, TuneIn, and Deezer.  The receivers use an Onkyo Controller app for iPad, iPhone, iPod touch, and Android devices.

Network streaming services can be shared from the receiver to optional NCP-302 speakers over FireConnect powered by Blackfire, while analog signals input via external audio terminals can be wirelessly distributed, including vinyl albums from the phono input, the company said.

Other convenience features include streaming via AirPlay and supported music apps via Chromecast built-in, as well as the DTS Play-Fi app. Bluetooth technology is included for wireless transmission to supporting devices within range.

The Onkyo Controller remote app will also access personal music libraries on home media servers, including files recorded in Hi-Res Audio formats including: Direct DSD 11.2 MHz, DSD 5.6 MHz, Dolby TrueHD, FLAC, WAV, AIFF, and ALAC to 192 kHz/24-bit resolution.

The TX-RZ620 and TX-RZ720 include wired connectivity through Powered Zone 2 speaker outputs and pre-/line output serviced by a DAC for network, S/PDIF, and analog sources. The TX-RZ820 has Powered Zone 2 outputs, Powered Zone 3 outputs, and Zone 2/Zone 3 pre-/line outputs. All incorporate independent balance, tone, and volume controls for each zone.

The TX-RZ820 also features VLSC on all seven channels (other models Front L/R channels); an aluminum front panel, door, and volume control; 7.2-channel pre-outs for outboard amp connection; and Whole House Mode for easy simultaneous multi-zone audio playback.

For home system integration the receivers include a 12 V trigger output, IP control and setup over LAN, RS-232 terminal, IR input, and optional rack-mount kit.
