The unpretentious Marantz SR5012 is an exciting addition to the latest collection of AVRs on the market. Its middle of the road amplification and processing is a match with the lower price tag. It has many comparable features found in the upscale SR6012, which was released at the same time with a cost $500 beyond the SR5012’s $999 MSRP. The 5012 handles 7.2-channel processing with style, thanks to Audyssey MultEQXT room calibration and its ability to control the seven 100-watt amplifiers in the chassis. The immersive audio content of DTS:X and Dolby Atmos works with both 5.1.2 and 5.2.2 channel configuration. Other features, such as an on-screen Setup Assistant and wireless connectivity, demonstrate the unit’s ability to deliver a dynamic presentation to new and seasoned home theatre fans of all ages.

Part of the current trend of other A/V companies, the objective is to get a superlative product to the public now and complete the updates when available. Two future firmware updates will increase the AVR’s performance. Enhanced Audio Return Channel (eARC) will support DTS:X or Dolby Atmos via TV apps. The setup is simple, requiring only one HDMI connection. The second update, Hybrid Log Gamma (HLG) passthrough, will support future HDR broadcast content.

Comparison Between Marantz SR5012 and Previous Model SR5011

Like the SR5011, the SR5012 is gaining recognition for listening pleasure. Natural, pure clarity is typical in an average sound range, whether utilizing audio alone or audio and video together. The 5011 has ARC (Audio Return Channel), while the 5012 will receive a firmware update for enhanced ARC. eARC ‘s single-cable connection improves performance by supporting Dolby Atmos or DTS:X from the TV apps. This bumps the AVR’s delivery up a couple of notches because it can handle a 5.1 surround sound speaker system with an additional four overhead speakers. Both units are at the lower end of the upscale Marantz AVRs and lack the ability to disturb the neighbors with loud, persistent sound. However, output is suitable for a home theatre experience. Online and onscreen guides make setup easy, as the HDMI ARC one-wire TV connection.


  • Dual subwoofer outputs. Use the subwoofers in different locations to balance low-frequency bass in the room.
  • Multi-source and Multi-room sound. Listen to stereo sound in one room while providing 5.1 channel surround sound to the main room, or keep 7-channel sound with additional setup options.
  • Smart TV connectivity on certain televisions permits remote handset control with HDMI CEC.


  • Over-driving the amp may cause overheating and a degraded audio performance.


The Marantz SR5012 is ideal for custom installs because of its IP control and RS232 port. It supports audio and hi-res formats like FLAC and WAV. Dolby Atmos and DTS:X deliver an amazing 3D home theater experience. Surround sound and amplifiers delivering 100 watts per channel spread audio to the nooks and crannies of the room with the support of Audyssey MultEQXT. Because it is ISF calibration ready, professionals can calibrate it to deliver expanded video performance.
