Flexible digital signal processing

Clara D1+ allows any digital input signal to be fed in regardless of its sample rate and clock settings thanks to the software-switchable sample rate converter. This makes it easier to connect different digital devices without separate synchronization lines.

Extended connection options

The sound system has a word clock input and output as well as two MIDI inputs and outputs. The expansion card is connected to the sound card via a ribbon cable and can be placed in a free slot in the computer housing.

Precise audio processing with high dynamics

With a resolution of 24 bit / 192 kHz and balanced XLR connectors, Clara D1+ delivers a detailed and dynamic audio performance. The switchable input SRCs achieve a dynamic range of 144 dB, while the ultra-low jitter of less than 1 ns ensures precise synchronization.

High compatibility and reliable drivers

Compatible with popular Thunderbolt PCIe adapters, Clara D1+ offers easy integration into modern systems. Windows drivers are available and lifetime quality support guarantees long-lasting reliability and support.
