Model Number: AT-HD-M2C

The Atlona HD-M2C is the ideal audio signal conversion solution for whole-home AV systems where matrix switching is core. Content from multichannel sources such as Blu-ray players, set-top boxes (STB) and game consoles can be distributed to multichannel and 2-channel capable zones simultaneously, ensuring compatibility, reducing system complexity and eliminating the expense of separate dedicated sources for each zone.

Comprehensive Audio Signal Format Conversion & Compatibility

Today’s audio signals come in many formats, yet many displays and legacy receivers are limited to what they can receive and output. The Atlona HD-M2C is engineered to be compatible with virtually all digital audio formats including lossless and lossy (compressed/uncompressed) formats.

With its plug and play capabilities, requiring no programming, the M2C is unique to the market and perfect for any residential system. The HD-M2C is a true powerhouse in a small package that converts/down-mixes multichannel HD audio formats like Dolby® Digital Plus, Dolby® TrueHD, DTS-HD Master Audio™ to 2 channels.

The M2C is designed to integrate seamlessly with all Atlona HDMI switchers including the H2H, PRO2HD, PRO3HD series, as well as many other matrix switchers available.

Challenge
Sharing common sources in mixed 2ch and multi-channel zones results in a degraded home theater audio experience. The multichannel zone, HD 5.1 home theater for example, is forced to accept the compatible low performance audio stream required for a 2ch zone such as a flat panel TV.

Solution
The HD-M2C solves this dilemma by allowing the distribution of full audio to each zone and seamlessly down mixing from sources such as lossless HD audio. No audio compromises required, enjoy the best HD audio for your home theater and simultaneously enjoy 2ch audio in the kitchen or bedroom.

Optional Upgrade: HD-M2C Multi-channel HDMI output
Firmware version 2.1.0 modifies the standard HD-M2C HDMI output behavior from 2ch down mix to multi-channel pass through. A Blu-Ray player 7.1 DTS HD-Master Audio stream will simply output the HD-M2C completely intact. This allows a multi-channel signal to be transmitted to an AVR and a 2ch analog signal to a multi-zone audio amplifier simultaneously!

  Sometimes there is an audio delay when changing channels on my cable/satellite set top box, why is that?
  This audio delay occurs when there is an audio format change. An example would be if one channel was broadcasting a 2CH. PCM signal and was switched to another channel that is broadcasting a Dolby Digital signal. There will be a slight 1-2 second delay in audio to prevent any kind of audio distortion or popping.

  Does the AT-HD-M2C let me play Multi Channel through the HDMI and stereo through the other outputs?
  It depends on the firmware you have on your AT-HD-M2C. Only FW 2.1.0 and above support Multi Channel via HDMI output. See "Firmware Updates" tab to download the latest firmware.

  Can I use extenders to go into our come out of the AT-HD-M2C?
  It is possible to use extenders with this unit, we recommend using any HDBaseT extenders such as our AT-HD(TX/RX) family.

  Can the AT-HD-M2C be left on constantly?
  The AT-HD-M2C does not need to be powered off and can be permanently left on.
