The DrPhone DAX2 is a compact digital audio converter that converts and splits Toslink and digital coaxial S/PDIF signals. Ideal for those who want to connect devices with different digital audio connections without software or complicated configuration.
Main advantages
- Supports conversion from Toslink to coaxial and from coaxial to Toslink
- Physical selector switch for easy input selection
- Selected signal is simultaneously output via Toslink and coaxial outputs
- Compact size of approximately 4.8 × 4.8 × 1.9 cm and lightweight of approximately 73 grams
- Works without software or drivers, powered via USB cable
Challenge and solution
Not all digital audio devices have the same connection, which complicates connection. The DrPhone DAX2 solves this by converting and splitting digital Toslink and coaxial S/PDIF signals, allowing devices with different digital inputs and outputs to work together seamlessly.
What is this product used for?
- Connecting TVs, Blu-ray and DVD players to amplifiers or soundbars with different digital audio connections
- Splitting one digital audio source to two devices with Toslink and coaxial S/PDIF
- Digital audio setups with media players, TV boxes, receivers and active audio systems
Technical explanation
The converter has two digital inputs: one optical Toslink and one coaxial S/PDIF via RCA. You select one active input with the physical switch. The selected digital signal is simultaneously passed through the Toslink and coaxial outputs. The converter converts digital signals between Toslink and coaxial without decoding or changing the audio format. Power is supplied via a USB cable, without the need for software or drivers.
