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 only one PCIe slot width, the Seraph AD8 MKII provides the connection for 32 audio channels. The balanced analog inputs and outputs are located on the motherboard. The digital AES/EBU connections, on the other hand, break out on a D-Sub connector without further active electronics. Consequently, it can freely be placed in the computer’s case, separately from the motherboard. Or it may take any place next to other PCIe components with the slot bracket.

Highest audio quality for analog and digital signals

With 115 dB dynamic range and a THD+N of less than 0.001% at -1 dBfs, the analog connections of the Seraph AD8 MKII play in the top sound league. A hefty level of +15 dBu provides enough headroom at the inputs and sufficient signal at the outputs for any connected device. Analog and digital processing is 24 Bit and 192 kHz throughout, with no restrictions on the number of channels.

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.

Realtime Mixing and EQ

Each input signal of the sound system can appear on up to 8 mix sums and be played back via any number of outputs without delay. The BEAST Mixer also adds playback signals from any DAW latency-free. Inside the hardware and for each signal, sonic processing is available with up to 4 parametric EQs.

Expansion Options

If several Seraph are installed in a 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 8 audio signals can be exchanged with other Seraph or Clara sound systems and thus be integrated for the use with ASIO.
