HDMI to BNC Audio Adapter

The Boxwave adapter converts an HDMI digital audio signal into a 3.5 mm stereo analogue output. It also passes standard-definition video at 480i or 576i through a BNC connector for display on regular televisions. A built-in DAC chip handles the conversion while HDCP signals are recognised automatically.

Suits legacy recording and display setups

Installers connecting modern HDMI sources to VHS recorders, DVD recorders or older televisions that only accept BNC input will find this unit useful. It is not intended for buyers who need high-definition or progressive-scan video output, nor for systems requiring multi-channel digital audio passthrough.

Handles NTSC and PAL standard definition

The adapter comfortably processes 480i and 576i interlaced formats for compatibility with NTSC and PAL equipment. It does not support higher-resolution modes, so 720p, 1080i or 1080p signals will not be displayed correctly.

Questions about this item

What HDMI source resolution does the adapter require to output 480i or 576i video?

The adapter supports 480i and 576i standard definition video formats, so the HDMI source must provide a compatible NTSC or PAL signal for the BNC output.

Will the 3.5 mm stereo output work with the RCA audio inputs on my older VCR?

The adapter converts HDMI digital audio to a 3.5 mm stereo analog signal; you will need a 3.5 mm to dual RCA cable to connect to the VCR's L/R audio inputs.

How can I confirm the adapter is correctly converting the HDMI signal after I connect it?

A stable 480i or 576i picture on the television and audible stereo sound through the 3.5 mm jack indicate the DAC chip is processing the HDMI input correctly.
