PT-C-HDAEDE – HDMI 2.0 Audio Embedder/De-Embedder: Signal Routing and Audio Management for 4K AV Systems
The PT-C-HDAEDE combines HDMI 2.0 video switching with advanced audio embedding and de-embedding, supporting resolutions up to 4K 60Hz (4:4:4) and a total bandwidth of 18Gbps. Designed for professional AV installations, this unit enables precise routing and manipulation of audio signals, including microphone and line-level mixing, within meeting rooms, workspaces, or control environments. The device accommodates both digital and analogue audio sources, offering flexible integration with balanced outputs and S/PDIF, as well as support for ARC and CEC pass-through. Downscaling, firmware updating via USB, and compliance with HDCP 2.2/1.4 further enhance deployment versatility in hybrid and signage applications.
Comprehensive Audio Embedding/De-Embedding: Audio signals can be embedded into or extracted from HDMI streams, utilising both digital and analogue I/O. This facilitates integration of external microphones or line-level sources, while enabling separate audio routing to amplifiers or recording systems within AV infrastructures.
Full 4K60 HDMI 2.0 Support: The unit processes video signals up to 4K UltraHD at 60Hz (4:4:4), with a maximum bandwidth of 18Gbps. Deep Colour (12-bit) and HDR compatibility ensure high-fidelity video transmission across modern display and projection systems.
Advanced Audio Signal Processing: Complex audio manipulation is supported, including MIC/LINE mixing and replacement of HDMI-embedded audio. Volume control and 48V phantom power accommodate a range of microphones, allowing flexible audio management in conferencing and presentation setups.
Digital and Analogue Audio Outputs: De-embedding options include balanced analogue (PCM 2.0) and digital S/PDIF (up to 5.1), supporting LPCM up to 7.1/24-bit/96kHz, Dolby Atmos, and DTS-X passthrough. This enables direct connection to professional audio equipment or distributed sound systems.
Downscaling and ARC Pass-Through: Integrated downscaler converts 4K video to 1080p for legacy displays, while ARC and CEC pass-through maintain compatibility with audio return channel and control protocols. This feature set supports mixed-technology environments and ensures operational continuity across diverse AV deployments.
Integrated Audio and Video Signal Management
By combining high-bandwidth HDMI 2.0 processing, flexible audio routing, and support for advanced formats, the PT-C-HDAEDE enables streamlined AV signal management in professional environments. The inclusion of downscaling, firmware update capability, and broad compliance with audio and video standards supports seamless deployment in meeting spaces, control rooms, and hybrid AV installations.

The PT-C-HDAEDE's ability to freely combine the various audio input and output signals allows it to be used as a simple audio de-embedder or embedder, but also as a voiceover unit, microphone preamp or audio mixer in more complex situations.
Four DIP switches on the front of the unit control the entire mixing behaviour of the PT-C-HDAEDE. A total of 16 switch combinations can set just about any conceivable output format configuration available. The four DIP switches control the following settings, in this order: 1. enable / disable analog audio input, 2. enable / disable HDMI input audio, 3. HDMI output audio configuration, 4. S/PDIF output audio configuration. An exact description of the procedure can be found in the detailed manual.
Also on the front panel there a toggle switch with three possible positions can be found which determines the format of the analog audio input. Here it is possible to choose between a "Line", "Mic" or a "Mic 48V" format. The latter setting is suitable for integrating a (condenser) microphone that is supplied with 48V phantom power.
HDMI input and output both support the reverse transmission of an audio signal via ARC.
The integrated HDMI downscaler can rescale an incoming 4K signal to FullHD / 1080p, making the PT-C-HDAEDE compatible with both modern and older display devices.
The Micro USB port allows for easy firmware updates.
Two additional buttons on the front panel control the volume of the analog audio input in a range from -18dB to +24dB in 1dB steps.
The 5V / 1A power connector on the back of the unit is screwable, making it suitable for professional installations. A power LED also indicates the operating status.
The compact housing with an overall size of 151 x 93.5 x 21 mm takes up little space during installation and weighs just 360g. This means that the PT-C-HDAEDE can be installed and operated invisibly and in the smallest of spaces, e.g. in an AV rack in a server room or in a lowboard.
