Go Further with More

  • Extend your audio/visual experience up to 328ft(100m) over CAT5e/6/7 cables. This HDBaseT based technology allows you to send IR, RS-232, video (up to 1080p or 1920x1200) and audio (all Lossy and Lossless formats) signals over a single CAT5e/6/7 cable.

Bidirectional Control

  • Compatible with all 3rd party controllers and IR remote controls, get bidirectional control from the RS-232 and IR ports. Control the matrix and the in zone displays with RS-232 or control all connected devices with the new zone dedicated IR ports.

No Device Left Behind

  • Ensure that even the most difficult display can receive audio and video with 8 programmable memory presets loadable to any source connected to the matrix.

Back Up Power Supply

  • In the event the main power supply becomes inoperable the built in redundant power supply will seamlessly take over the matrix’s energy needs.

  Why is the unit not responsive after the firmware update?

This unit cannot be updated via Mac computers and if it did, the unit will not boot up properly. To fix this:

    1. Unplug both power supplies on the back of the unit.
    2. Press and hold the cancel button.
    3. While holding the cancel button, reinsert the power cord into the unit. The unit should now boot up in ISP mode and be able to be updated with a standard PC.

  I can only get 2-channel audio on my A/V Receiver when viewing one source on multiple displays.

When multiple displays are viewing a single source, the source will output a common format that all screens can handle. So when all of the sources do not have A/V Receivers the source will default to a common 2-channel audio format.

*In order to get multi-channel audio to the AVR, you need to assign a multi-channel EDID to any source that you want a multi-channel signal from. Some displays may not be able to down mix a multi-channel signal and will result in no sound or a repetitive clicking sound.

You can learn EDID or use the internal EDID. Please refer to user manual.

  How do I embed analog audio into the input port?
  Untitled Document If you have a DVI source, this should work without any issues; however if you have HDMI source (the audio which is residing on HDMI channel) takes priority over the Stereo Audio input. There is a way to overcome this by selecting a DVI EDID mode for that input source, this will allow switch to think that it is connected to a source without audio and will auto embed audio from Stereo interface. Please refer to the user's manual for the DVI EDID modes (Page # 11). Please make sure you have the latest firmware 1.1.25

  Why Can’t I get video on ZONE-x?
  If you have already checked your cables and receivers, try doing an EDID learn and assigning the learned EDID to the input. Second, try assigning pre-loaded EDIDs.

  I have a mix of 720p and 1080p TVs, and I want my 1080p TVs to get full resolution.

In order to get 1080p resolution, you will need to do an EDID learn from a 1080p display and store it to the sources. In order for the 720p TV to get signal, you will need to use an HDMI down converter, the AT-HD560 and set the resolution to 720p.

  Why my unit keeps locking up?

Please make sure your firmware is updated to at least version 1.1.25. If problem still persists, please do the Factory Reset: With the matrix in the off state, hold button 1 and 4, then push the power button. Continue to hold 1 and 4 until you see “Setting Factory Default”. Second, if factory reset does not solve the issue, then reload firmware. To reload firmware, please check the user’s manual posted on Atlona’s product webpage under Documentation tab.
