Marantz SR5012

The video section features 8 HDMI inputs (including 1 on the front panel), with full compatibility with the latest 4K Ultra HD video specification, including 60 Hz full rate content, 4:4:4 Pure Color sub-sampling, BT.2020, HDR and Dolby Vision compatibility. It's also HDCP 2.2 compliant, for 4K Ultra HD copy-protected content. HLG (Hybrid Log Gamma) pass-through for future HDR broadcast content will be supported via a firmware update. The SR5012 should allow for a complete array of high-definition sources to be connected, including Blu-ray Disc players, streaming devices, set top boxes and games consoles, with 4K video and hi-res audio as well as upscales legacy video sources (e.g. DVD) to 4K.

The SR5012 even creates immersive surround fields from older soundtracks using Dolby Surround and Neural:X processing as well as being compatible with Dolby TrueHD and DTS-HD soundtracks for conventional 5.1- or 7.1-channel surround. With the SR5012 you can create a 5.1 surround sound speaker system and 4 additional overhead speakers or 4 Dolby Atmos elevation speakers (both with an additional 2 channel amplifier) for the ultimate 5.1.4 home theater experience - including Dolby Surround upmixer for legacy content. In addition, the SR5012 will support eARC (Enhanced Audio Return Channel) for Dolby Atmos or DTS:X from your TV apps with a single HDMI connection. This feature will be enabled via a future firmware update.

All seven channels of the SR5012 are identical in design and built from high-quality components including Marantz' Hyper Dynamic Amplifier Modules (HDAMs). The SR5012 handles digital to analog conversion through its eight-channel DAC block, using 32-bit AKM's AK4458VN D/A converters on all channels. It features low-impedance drive capabilities that should provide for excellent speaker control even with 4-ohm speakers. For energy conservationist, SR5012 comes with an Eco mode but we don't recommend using the Eco mode if your concern is maximum power delivery to your speakers. It features an on-screen Eco meter that allows you to use the receiver in power-saving mode, either reducing the maximum output power or adopting low-power strategies at more modest settings. 

The SR5012 features a wired or Wi-Fi connection to access your music through your home network. This includes Internet radio and streaming services such as Spotify, Connect, Tidal, and Pandora. The SR5012 can also stream music from a computer or NAS drive at up to 192kHz/24bit and DSD5.6MHz for ALAC, FLAC, and WAV lossless files as well as DSD 2.8MHz and 5.6MHz tracks (the audiophile format of SACD). You can also play hi-res music via the front panel USB port and network sources, and also listen to other popular file types such as MP3.Direct streaming from a smartphone or tablet via Bluetooth or Apple Airplay.

For optimal performance, the SR5012 comes with Audyssey MultEQ XT and Audyssey App editor capability which can be used to simplify accurate set-up and calibration to customize your sound.

Additional features of the SR5012 include an on-screen Setup Assistant to make it easy to install and configure the AVR, color-coded speaker terminals to simplify connections and an Intelligent ECO mode to minimize power consumption without compromising performance. The SR5012 is also ISF calibration ready, allowing professionals to precisely calibrate it for even better video performance with the user’s display.

 

Marantz SR6012

 

The SR6012 takes the SR5012 to the next level with 11.2-channel processing, preouts and extended custom installation features including Crestron Connected compatibility. Its identical nine channels of amplification should offer smooth performance during playback and includes Marantz HDAMs to deliver high-resolution quality with both music and movies.

With low-impedance drive for even the toughest speaker loads, the SR6012 can drive 5.1.4 or 7.1.2 speaker configurations out of the box to deliver an immersive 3D sound of Dolby Atmos and DTS:X. It's 11.2-channel processing even allows 7.1.4-channel to work with an extra two-channel amplifier. Dual subwoofers capability allows smoother and more dynamic bass reproduction.

Three HDMI outputs allow audio and video to be sent to a second zone, as well as two additional displays (e.g., TV and projector) simultaneously. The SR6012 will also support eARC (Enhanced Audio Return Channel) via a future firmware update to allow object-based audio, including Dolby Atmos and DTS:X playback from TV video apps via a single HDMI cable.

The SR6012 has a higher-precision Audyssey MultEQ XT32 set-up and calibration and also has extra audio input (five, as compared to four on the SR5012) and a moving magnet phono input to allow a turntable to be connected. Other performance-enhancing additions include an aluminum front panel for greater rigidity, a Hybrid PLL Clock Jitter Reducer for the most accurate audio reproduction, and an extruded aluminum heatsink for more efficient heat-dispersion. The SR6012 also features gold-plated connectors and speaker terminals. 

Most Affordable 11.2CH Immersive Surround Preamp is a Receiver?

The SR5012 will retail for $999 and the SR6012 for $1,499 are avaiable through authorized Marantz retailers.

Think about this.  Even if you prefer to use external amplification for ALL of your speakers, the SR6012 may just be the most affordable 11.2CH Atmos/DTS:X processor solution on the market!  With all these features the SR6012 offers for $1,499, it will be interesting to see if their sister company Denon refreshes their similarly equipped AVR-X4300H model in the months to come. The AVR-X4300H offers a tad more amplifier power (125wpc compared to 110wpc of the SR6012). But, the Marantz SR6012 focuses more on the quality of the preamp outputs with its HDAM circuits making it the more ideal solution for those wanting to use it as a dedicate preamp/processor.  You can't go wrong with either model if your looking to assemble an 11.2CH immersive surround theater system and also handle the latest in music streaming too.
