To convert optimized audio signals from source to display, the AT-HD-M2C uses EDID (Extended Display Identification Data) which they say results in automatic signal detection and delivery and includes discreet status lights for PCM, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS Digital Surround and DTS-HD Master Audio allow users to determine the incoming audio signal at a glance.
For amplifiers and legacy audio receivers, a variety of output ports such as L/R analog audio, coaxial, and TOSLINK digital audio enable pass-through even without HDMI support, while retaining the ability to distribute both audio and video to HDMI displays.
