Overview

The Marantz CINEMA50SG is an AV receiver with 9 HDMI ports and Wi-Fi connectivity, rated at 110 watts and finished in silver. It suits home theater builds that need to switch between many HDMI sources.

Nine HDMI ports is well above what a typical soundbar or budget receiver offers, making this a hub style unit meant to sit at the center of a multi device setup rather than a simple stereo amplifier. At 16.62 pounds and over 15 inches deep, it is sized like a full component rather than a compact box.

  • 9 HDMI input ports
  • 110 watt rated power
  • Wi-Fi connectivity
  • Silver finish, 16.62 pound build

Who it's for

Fits a dedicated home theater room with several HDMI sources such as a console, streaming box, disc player and cable box all needing a home. Not the pick for a simple two speaker setup where fewer HDMI inputs would do.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • 9 HDMI ports for multiple sources
  • Wi-Fi connectivity built in
  • 110 watt rated power
What to check first
  • Larger footprint than a compact receiver
  • Weight makes it less portable
  • Very few reviews to reference

Performance notes

Power rated at 110 watts is a per channel or reference figure typical of mid to high tier receivers, with real output depending on how many channels are driven at once and the speakers connected. The 9 HDMI ports allow source switching without unplugging cables, which is the main practical benefit of a receiver this size.
