HDMI audio extractor PREMIUMCORD khcon-30 — 4K input, stereo 3.5mm jack and optical SPDIF output

The PREMIUMCORD khcon-30 is an HDMI audio extractor and repeater that separates audio from an HDMI 4K input and provides both analog and digital audio outputs. It extracts audio to a 3.5 mm stereo jack, an RCA coaxial digital output, and an optical TOSLINK SPDIF connector while also equalizing the HDMI signal to extend transmission distances when using quality AWG26 HDMI cables.

Advantages

This unit converts HDMI audio to analog stereo and to digital optical or coaxial outputs without modifying the video signal, supports resolutions up to Full HD 1080p and 4K (4096x2160), is HDMI and HDCP compatible, supports 3D video and HDMI 1.4 features, and includes EDID management via DIP switch and LED status indicators. A 5V/1A power supply is included.

Suitable for

• Connecting TVs or monitors to external speakers or soundbars that require 3.5 mm analog input
• Feeding digital audio (TOSLINK or coaxial RCA) to AV receivers or recording devices
• Integrating legacy audio equipment with modern HDMI sources
• Extending HDMI signal over longer runs while extracting audio

Key specifications

• Inputs: 1× HDMI female (4K input)
• Outputs: 1× HDMI female (repeater output), 1× 3.5 mm stereo jack (analog), 1× RCA coaxial digital audio, 1× TOSLINK optical SPDIF

• Signal extension: up to 15 m for 1080p or up to 10 m for 4K using AWG26 HDMI cable
• Power: 5V/1A adapter included
• Controls: DIP switch for EDID management; LED status indicators

How to use

Connect the HDMI source (e.g., Blu-ray player, set-top box, game console) to the HDMI input. Connect the HDMI output to a display if video pass-through is required. For audio, connect speakers or a soundbar to the 3.5 mm jack for analog output, or use the TOSLINK optical or RCA coaxial output for digital audio. Plug in the supplied 5V/1A power adapter and set EDID options via the DIP switch if needed. Use high-quality AWG26 HDMI cables for longer runs to achieve the stated extension distances.

Usage recommendations

For reliable 4K transmission and optimal audio extraction, use certified AWG26 HDMI cables, verify EDID settings to match your display and audio device capabilities, and ensure the power adapter is connected. If you experience signal drop or audio sync issues, reduce cable length or check cable quality and EDID configuration.
