## Summary description

ATEN HDMI/Audio Over Cat5 Extender with MK is a wired AV transmitter and receiver kit that extends HDMI video and audio over Cat5e/Cat6 cabling up to 1920×1200 resolution. The set includes transmitter and receiver units powered at 9 V, supports HDMI audio pass-through, and is suited for signal extension in conference rooms, classrooms and digital signage installations.

## Long description

The ATEN VE807 HDMI/Audio Cat5 Extender with MK wall plate is a wired AV transmitter and receiver kit designed to fit a one-gang MK-type junction box. It extends HDMI video and audio signals over Cat5e/ Cat6 cabling and supports resolutions up to 1920 x 1200. The kit includes a transmitter and receiver with MK wall plate covers, power adapter, terminal block connector and mounting hardware for in-wall installation in markets using MK junction boxes.
Advantages
This extender transmits HDMI video and audio up to 60 m using two Cat5e/6 cables, preserving HDCP authentication and EDID information. It supports high-definition video up to 1080p@60Hz at shorter distances and 1080i@60Hz up to the maximum range, with an 8-segment equalization switch to optimise signal quality. The units are sized and supplied for convenient mounting in MK-type one-gang junction boxes.
Suitable for
Extending HDMI audio/video in conference rooms and meeting spaces
Classroom AV installations and lecture halls
Digital signage and display walls where a neat in-wall finish is required
Setups requiring HDCP and EDID pass-through over structured cabling
When it may not be suitable
This solution requires two Cat5e/6 cables between the transmitter and receiver (one for video/audio and one for power/EDID/HDCP) and a compatible MK-type junction box; it is not appropriate where only a single cable run is available or where other junction-box standards are used. It is also limited to the specified maximum distances and resolutions, so it may not meet needs for longer-distance runs or resolutions above 1920 x 1200.
Key specifications
Video format support: up to 1920 x 1200 (supports 1080p@60Hz at shorter distances, 1080i@60Hz up to 60 m)
Maximum transmission distance: up to 60 m over Cat5e/Cat6
Cabling: requires two Cat5e/ Cat6 cables between units
Mounting: fits one-gang MK-type junction box
EDID and HDCP: pass-through/ authentication supported
Signal adjustment: 8-segment equalization switch
Power: external wired DC power input (included adapter)
Colour/finish: white wall plate units
How to use
Install the transmitter and receiver into compatible one-gang MK junction boxes and connect each unit to the HDMI source and display respectively. Run two Cat5e/6 cables between the transmitter and receiver—one cable carries video and audio, the other carries power, EDID and HDCP signals. Connect the supplied power adapter to the wired DC-in jack or use the terminal block connector per the included instructions. Adjust the equalization switch if required to optimise image quality over the installed cable length.
What to consider before purchase
Availability of two Cat5e/ Cat6 cable runs between source and display locations
Presence of MK-type one-gang junction boxes at mounting points
Required display resolution and maximum cable length for your installation
Need for HDCP and EDID pass-through for source/display compatibility
Usage recommendations
For reliable performance, use quality Cat5e or Cat6 cables, keep cable runs within the specified maximum distance, and verify HDCP/EDID compatibility between source and display. If image degradation occurs at longer runs, use the equalization switch to fine-tune signal quality.
