Overview
This is an Amazon Renewed unit of an Onkyo AV receiver, model TX-NR5100, offering 6 HDMI ports and 80 watts of rated power for a home theater setup.
Sold through Amazon's Renewed program, this receiver has been inspected and resold rather than bought new, which is worth factoring into any warranty expectations. The spec sheet attributes the brand technology to Onkyo, and 6 HDMI ports give it enough inputs for a multi-source home theater without needing a separate switcher.
- 6 HDMI ports
- 80 watt rated power
- Onkyo brand technology
- Amazon Renewed condition
Who it's for
Suits a home theater setup that needs multiple HDMI inputs and is comfortable buying Onkyo equipment through Amazon's Renewed program rather than new. Not for buyers who want new-condition equipment with full manufacturer warranty terms.
Strengths and trade-offs
Drawn from this product's published specifications.
- 6 HDMI ports for a multi-source home theater
- Onkyo brand technology per spec data
- Renewed condition, not new
- 80W power rating is modest for larger rooms
Performance notes
80 watts of rated power is on the modest side for a multi-channel receiver, suited to smaller or moderately sized rooms rather than large spaces, while the 6 HDMI ports handle switching between several source devices.
