Four-Input HDMI and HDBaseT Switcher

with Auto-Switching and Return Optical Audio

Introduction

The Atlona JunoX™ 451 HDBT (AT-JUN0-451-HDBT) is a 4x1 switcher for high dynamic range (HOR) formats.
The JunoX 451 HDBT features three HDMI inputs, plus an HDBaseT™ input for receiving video, embedded audio, and
Ethernet over distances up to 330 feet (100 meters). It is HDCP 2.2 compliant and supports 4K/UHD video @ 60 Hz
with 4:4:4 chroma sampling, as well as HDMI® data rates up to 18 Gbps. The JunoX 451 HDBT is ideal for receiving
4K HDR over HDBaseT from an Atlona Opus™ Series matrix switcher, and is also compatible with the Atlona UHD­PRO3, UHD-CAT, and SW Series for HDBaseT™ extension up to 10 Gbps. It includes EDID management features
and automatic input switching. The JunoX 451 HDBT also supports the HDMI Audio Return Channel for receiving
digital audio from a television and includes a TOSLINK digital audio output for sending this audio to an AV receiver or
soundbar. This JunoX Series switcher can be controlled via Ethernet, RS-232, and IR. A handheld IA remote control
is included.

NOTE: For HDR and 4K/60 4:4:4 content (HDMI data rates exceeding 10 Gbps), the AT-JUNO-451-HDBT is not
compatible with transmitters for the AT-HDR-EX-70-2PS, AT-HDR-EX-70C-KIT, or AT-HDR-EX-100CEA-KIT.
