Analogue and digital precision

The analog connections of the Clara B+ achieve excellent sound quality with 128 dB dynamic range. High-quality AD/DA converters ensure detailed signal conversion within a precisely tuned analog circuit. With levels of up to +24 dBu, the system offers sufficient headroom for professional use. The digital connections work with a maximum resolution of 24 bit / 192 kHz, while the analogue connections even support up to 32 bit / 384 kHz.

Advanced digital signal processing

The switchable sample rate converters allow flexible adaptation of incoming digital signals to the system, regardless of sample rate and clock settings. This makes it easy to integrate digital devices without the need for separate synchronisation lines. The integrated Beast DSP offers a powerful digital mixing console with 64 freely configurable channels, equalisers and flexible routing options.

Modular expansion with word clock and MIDI

The audio interface has an additional expansion card that provides a word clock input and output as well as two MIDI inputs and outputs. This extension is connected to the main card via a ribbon cable and can be placed in one of the slots of the computer housing in a versatile manner. This keeps the main card compact, while the additional connections provide extended synchronisation and control options.

Efficient drivers and flexible connection

The Clara B+ supports multi-client drivers for ASIO 2.2, multi-channel WDM audio and WASAPI. These enable simultaneous use by multiple audio applications with minimal latency. The PCIe interface complies with PCI Express Base Specification 2.1 and uses a 1-lane slot for maximum compatibility. In addition, the system is compatible with common Thunderbolt PCIe adapters so that it can also be easily integrated into modern setups.
