Digital to Analog Audio Converter with Flexible Input and Multi-Output Support Key benefits - Flexible digital to analog conversion: accepts coaxial and fiber optic digital audio inputs and converts them to analog stereo L/R and 3.5 mm output for wide compatibility with legacy and modern audio gear. - HDMI ARC ease of use: when connected via a standard HDMI cable, TV audio can be output through HDMI ARC to optical, coaxial, L/R and 3.5 mm headphone jacks, and all outputs can operate simultaneously. - Remote controlled volume with ARC: using the TV ARC function, you can adjust volume with your TV remote control. This capability supports RCA left/right and 3.5 mm output interfaces. - Low power consumption: designed to minimize energy use while delivering stable, reliable audio performance. - Broad compatibility and practical design: suitable for home theaters, classrooms, training facilities, conference rooms, and retail showrooms, enabling flexible distribution of TV and digital audio to multiple destinations. What it does - Converts digital audio signals from coaxial or optical inputs into high quality analog audio for L/R speakers and 3.5 mm headphones. - Provides HDMI ARC input for TV audio, with simultaneous outputs to optical, coaxial, RCA L/R, and 3.5 mm jacks. Compatibility and inputs - Input sources: coaxial digital audio, optical (fiber optic) digital audio, and HDMI ARC from a TV via a standard HDMI cable. - Output destinations: optical output, coaxial output, RCA left/right audio, and 3.5 mm headphone jack. Output can be used in combination, enabling flexible setup across multiple devices. Use scenarios - Home theater setup: connect the TV to the DAC via HDMI ARC to send TV audio to multiple outputs. Route the analog L/R to a stereo amplifier, and connect the 3.5 mm or RCA outputs to additional speakers or a secondary system. - Classroom or conference room: use the HDMI ARC TV connection to feed room speakers via RCA or 3.5 mm outputs, while maintaining a separate digital path for recording or amplification equipment. - Retail showroom or appliance store: distribute TV audio to several display speakers and store demo headphones, enabling clear sound across multiple listening zones with a single TV source. Notes - HDMI ARC requires a standard HDMI cable for TV connection. - When using ARC, volume control via the TV remote is supported, but only for RCA left/right and 3.5 mm outputs. Performance highlights - Converts digital to analog with reliable, real world audio quality suitable for home, classroom, and commercial environments. - Supports simultaneous multi-output operation, simplifying setups that require multiple listening stations or output formats. - Energy efficient design suitable for extended use in various environments.
