Up to 128 bi-directional channels, long distance connectivity through low cost network cables and infrastructure, sample rates up to 192 kHz, auto-configuration – all these advantages of the Dante protocol are now available with the Clara E at an amazingly affordable price. Unlike virtual solutions, the Clara E offers the security of the redundancy of 2 separate network connections and, in conjunction with the reliable PCIe interface, latencies of 1 ms.

Fast and Reliable Multi-Client Treiber Suite

The continuously enhanced driver includes multi-client support for ASIO 2.2 as well as multi-channel WDM audio / WASAPI with the lowest latencies in all software environments. This ensures that multiple audio applications can access the sound system simultaneously via the same or different driver interfaces.

Expansion options

An optional plug-on module serves as a bridge to the classic audio formats and expands the Clara E with AES/EBU, ADAT or analog interfaces. In the routing and in the Beast Mixer the signals of these interfaces are available as well and can thus be integrated into the Dante network.

If several Clara E are installed in one computer, they are synchronized via the TDM SyncBus and appear as a combined sound system to an ASIO application. In the Beast Mixer, up to 32 audio signals can be exchanged with other Clara sound systems (e.g. Clara Dmaj) and thus also be integrated for use with ASIO.

Sound system with a +

The “+” version includes an extension that adds a word clock input and output and 2 MIDI inputs and outputs to the sound system. This expansion card is connected to the sound card via a ribbon cable and can therefore be freely positioned in one of the slots of the computer housing.

Powerful and Future-Proof

Every MARIAN sound system is a quality product developed 100% in Germany and manufactured according to DIN EN ISO 9001. This is guaranteed by its warranty period of 5 years.
