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.

In the space of just one PCIe slot width, the Clara Dmaj provides the connection for 32 audio channels. The AES/EBU inputs and outputs 1 to 4 as well as a word clock input are located on the motherboard. Connectors 5 to 8 break out on a D-Sub connector which has no active electronics. Consequently, it can freely be placed in the computer’s case, separated from the motherboard. Or it may take any place next to other PCIe components with the slot bracket.

Precision Clock

The internal clocking of the Clara sound system has an amazingly low jitter of less than one nanosecond. This is beneficial to the audio quality of the system and that of any connected digital device. Often the clock of the Clara D is many times more precise than the internal clock of the connected device and thus makes the purchase of a separate clock generator unnecessary.

The highest Audio Quality

The Clara Dmaj is the elegant partner for pure digital signal processing of many AES/EBU signals. HD audio quality with 24 Bit and sample resolutions of up to 192 kHz guarantee a pristine sound. High-quality sample rate converters provide flexible clock management while maintaining a full dynamic range of 144 dB.

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.

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.

Expansion options

If several Clara D 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 and thus also be integrated for the use with ASIO.

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. All mix sums can be fed back to an application for recording. In each channel of the BEAST mixer there are 4 parametric EQ available for sonic processing.
