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.


Small form factor with top quality sound and craftsmanship make the Clara B ideal for mastering and broadcasting.

Available second quarter 2023.

Designed specifically for full-time operation in small desktop and server computers, this low-profile system delivers a useful mix of balanced analog and digital interfaces, sample rate converters, and configurable analog levels. The Clara B proves to be particularly versatile and reliable in professional environments such as broadcast and mastering.

Analog and digital excellence

With 128 dB dynamic range, the analog ports of the Clara B play in the top league of sound. The 32-bit AD/DA converters within a finely tuned analog circuit offer unsurpassed sonic pleasure. A high level of up to +24 dBu provides sufficient headroom at the inputs and sufficient signal at the outputs for any connected device.

Switchable Samplerate Converter (SRC)

The SRCs, which can be switched on via software, allow any digital input signal to be fed into the sound system regardless of samplerate and clock settings. Thus, even without separate synchronization lines, any digital devices may be connected effortlessly.

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.
