Why it works
Keep using analog speakers, amplifiers or headphones with digital optical and coaxial audio sources through one compact converter.
A powered optical/coaxial SPDIF-to-analog DAC with RCA and 3.5 mm outputs, PCM support up to 192 kHz / 24-bit, plus physical volume and bass controls.
Key benefits
Why you will keep it within reach
Control headphone level directly
A built-in headphone output and physical volume knob give you local level adjustment without relying only on the source device.
Adjust bass without another processor
The dedicated bass knob lets you change the low-frequency component directly from the converter for a simpler listening setup.
One compact box covers several output paths
RCA output can feed an amplifier or powered speaker setup, while the 3.5 mm jack provides a direct path for compatible headphones.
Details that matter
Product details
Connect Digital Audio Sources to Analog Speakers or Headphones
This DAC converts supported optical Toslink or coaxial SPDIF audio into analog stereo output through RCA or a 3.5 mm headphone jack. It is useful when a TV, game console, disc player or other digital source needs to feed older or analog audio equipment without a matching digital input.
Control Headphone Volume and Bass from the Converter
The unit supports PCM audio up to 192 kHz / 24-bit and includes physical volume and bass adjustment knobs. The supplied information lists support for 32–600Ω headphones. For correct operation, the source device should be set to SPDIF output using PCM format, and the volume should be turned down before powering on.
- Bridges optical/coaxial digital sources to analog RCA or 3.5mm equipment
- Built-in volume control can simplify headphone level adjustment
- Bass control gives you a direct way to change low-frequency output
How it works
Simple by design
Set the source to SPDIF PCM
Configure the connected TV, console or player to output compatible SPDIF audio in PCM format before use.
Connect digital input and analog output
Connect optical or coaxial audio into the DAC, then use RCA or 3.5 mm output for the compatible analog device.
Lower volume before power-on, then adjust
Turn the volume control down before powering the unit, then raise volume and adjust bass gradually after the signal is working.
