Atlona AT-HD4-V41 Overview

Switch four HDMI sources to a single HDMI output with this Atlona Four Input HDMI Switcher. This versatile device supports SD, HD, and VESA resolutions up to 1920 x 1200, and will allow for the pass-through of HDCP-protected content. Auto-switching capabilities make for painless operation, as the unit will automatically route the most recently connected/powered input to the output, avoiding the dreaded manual input cycle-through on power-up. If sending audio to a separate processor, a dedicated S/PDIF output is available with ARC compatibility. RS-232 connectivity provides remote control capabilities via software, while the included remote control provides a wireless option.


  • Automatically switches to the most recently connected or powered-up source
  • Activated using RS-232 adjustment

Audio Return Channel (ARC)

  • Audio is returned from the remote display's internal tuner or from any device plugged into it via HDMI to the S/PDIF audio output
  • Allows ARC-enabled TVs, such as smart TVs, to transmit audio back to an AV receiver through the same HDMI cable used to connect the input

3D Support

HD 3D video signals will be passed through to the display

Bidirectional HDMI Ethernet Channel

Use a single connection from your router to pass internet by HDMI cable to all your HEC capable devices


  • Supports audio loop-out
  • Supports digital audio de-embedding for up to DTS 5.1 and Dolby Digital
