marian DIGITAL AUDIO ELECTRONICS Clara D 16-Channel AES/EBU PCIe Sound Card

Key Features

• PCIe card with 4 AES/EBU digital I/O (16 channels)
• 24-bit / 192 kHz high-quality audio
• Ultralow jitter
• Switchable sample-rate converters (SRCs) on every input, with 144 dB(A) dynamic range 
• The BEAST Mixer: 64-channel DSP mixing desk with EQ
• Wordclock/Superclock BNC input
• Cascadable via MARIAN-SyncBus compatible and TDM-SyncBus 
• Synchronization as clock master (internal clock to the AES/EBU or the SyncBus)
• Synchronization as clock slave (processing an external clock at the wordclock input, AES/EBU, or SyncBus)
• Compatible with Thunderbolt PCIe adapters
• Driver support: MME, ASIO 2.2, WDM Audio, DirectSound

Highest Audio Quality

• The Clara Dj is a powerful partner for pure digital-signal processing of up to 16 AES/EBU channels with resolution up to 24-bit / 192 kHz for HD audio quality.
• High-quality sample-rate converters provide flexible clock management while maintaining a full dynamic range of 144 dB(A).

Switchable Sample-Rate 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 sample rate or clock settings. So even without separate synchronization lines, any digital devices may be connected effortlessly.

BEAST DSP Mixer for Realtime Mixing and EQ

• The BEAST Mixer is a 64-channel DSP mixer integrated into the card's hardware. It provides latency-free routing to any output. The BEAST mixer also sums up to 64 signals to 8 different buses and plays them back on any number of outputs. It also adds playback signals from any DAW�just like an analog mixer.
• All mix sums can be fed back to an application for recording. Each channel of the BEAST mixer offers 4 parametric EQs for sonic processing.

Expansion Options

• If several Clara D cards 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 64 audio signals can be exchanged with other Clara sound systems and integrated for use with ASIO.
