The PT-C-HDEARC-4K is an HDMI eARC adapter and audio extractor that allows de-embedding of eARC or ARC signals from a connected TV or extraction of the audio signal from a connected HDMI source device, with uncompressed transmission and a 720p black image to an AV receiver, amplifier, or soundbar. It is HDMI 2.0b and HDCP 2.3 compliant, supports a bandwidth of 18Gbps, resolutions up to 4K/UltraHD at 60Hz with HDR formats including HDR10, HDR10+ and Dolby Vision, and features one HDMI input and two HDMI outputs for separating AV and audio signals. The device supports various multichannel and stereo audio formats such as LPCM 5.1/7.1, Dolby Digital, Dolby Digital Plus, Dolby True-HD, Dolby Atmos, DTS 5.1, DTS ES 6.1, DTS HRA, DTS HD Master, and DTS:X; equalizes and reclocks HDMI signals for stable transmission; passes CEC; and offers DIP switches for EDID and eARC control as well as an EDID management feature. Important: No function with Sonos ARC, Sonos BEAM, Bose Smart Soundbar 300 etc.; these soundbars require a ‘real’ HDMI input and models with eARC port only cannot accept the signal.

Product description
The PT-C-HDEARC-4K is an HDMI eARC audio converter supporting HDMI 2.0b and HDCP 2.3, for resolutions up to 4K/UltraHD at 60Hz with a bandwidth of 18Gbps. It supports three application scenarios for connecting source devices, TVs, and AV receivers or soundbars, and features one HDMI input and two HDMI outputs. The second HDMI output always provides an uncompressed audio signal with a 720p black image, and audio extraction operates from eARC/ARC or HDMI input depending on DIP switch settings. If connected to an eARC/ARC port of a TV with 8K@60Hz or 4K@120Hz resolution, only the audio transmission is extracted via eARC/ARC signal.
Transmission
- Supports HDMI 2.0b specification including HDCP 2.3.
- Features one HDMI input and two HDMI outputs (for TV and AV receiver or soundbar).
- Handles equalization and reclocking of incoming signals for transmission over long distances.
- CEC signals are forwarded between devices.
Video
- Supports resolutions up to 4K / UltraHD at up to 60Hz with 18Gbps bandwidth.
- Supports HDR formats including HDR10, HDR10+ and Dolby Vision.
- The second HDMI output always provides a 720p black image with uncompressed audio.
Audio
- Compatible with multichannel audio formats including LPCM 5.1 and 7.1, Dolby Digital, Dolby Digital Plus, Dolby True-HD, Dolby Atmos, DTS 5.1, DTS ES 6.1, DTS HRA, DTS HD Master and DTS:X, as well as stereo signals.
- Second HDMI output always provides uncompressed audio with a 720p black image.
- When eARC extraction function is turned on, eARC or ARC signal is extracted at the second audio output.
- When eARC extraction function is turned off, the audio signal from the HDMI input is routed to the second output.
- If connected to an eARC or ARC port of a TV with 8K@60Hz or 4K@120Hz resolution, only the audio transmission is extracted (not video).
Control
- Includes EDID management function: allows reading and passing on EDID of connected TV or switching to a standard EDID if handshake fails.
- DIP switch on the front determines which EDID to read out.
- Second DIP switch turns eARC extraction function on or off.
Compatibility
- Supports three application scenarios: (1) Source device direct to TV, eARC/ARC signal passed to converter and then to AV receiver; (2) 4K source device connected to converter, signal forwarded to TV and audio extracted to AV receiver; (3) TV's internal receiver/media player eARC/ARC signal passed to converter and then to AV receiver.
- Acts as a middleman between older and newer generation devices for audio compatibility.
