The Beast

Analog-Style Mixing

The Beast DSP mixer is integrated into the hardware of every Seraph and Clara sound system. This provides latency-free routing, EQ processing, pre/post aux summing and many other functions for all input signals and also the playback signals from the DAW, just like in an analog mixer.


When it comes to sending and receiving extremely large numbers of audio signals over a network, the solution is called: Dante with the Clara E.

Up to 512 bi-directional channels, connection over long distances through low-cost network cables and infrastructure, samplerates of up to 192 kHz, auto-configuration – all these advantages of the Dante protocol are now available with the Clara E at an amazingly low price. In contrast to virtual solutions, the Clara E offers the security of redundancy with 2 separate network ports and latencies down to 1 ms in connection with the reliable PCIe interface.

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.

Realtime Routing, Mixing and EQ

Each input signal of the sound system can be adjusted in volume and routed latency-free to any output. The BEAST DSP mixer also sums up to 64 signals to 8 different busses and plays them back on any number of outputs without delay. Furthermore, the BEAST Mixer adds playback signals from any DAW. In each channel of the BEAST mixer there are 4 parametric EQ available for sonic processing.

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.

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.
