ADAU1701 DSP Audio Processor Preamp Crossover Board 2In 4Out Tone Control with SigmaStudio Support

Compact programmable preamp with DSP control for flexible audio applications Key features and benefits Powered by ADAU1701 DSP with a 28/56bit Digital Signal Processor Engine for precise digital audio processing and stable performance. Unbalanced 2In, 4Out preamp unit that simplifies signal routing for small systems and multizone setups. Four potentiometers provide handson control for pass filter, low pass filter, and independent volume adjustment, enabling fast onsite tuning without software. Supports SigmaStudio programming when connected via ICP5, allowing custom processing flows and improved conversion performance through tailored DSP configurations. Clear solution for adding digital processing to analog source signals, reducing setup time and enabling repeatable results across sessions. Functional highlights and compatibility Function: Preamplification, analog input splitting to multiple outputs, onboard analog filtering, and DSPbased processing. Compatibility: Works with SigmaStudio for DSP programming via ICP5 connection to create and upload custom filters, crossovers, EQ, and other signal processing blocks. Control: Frontpanel potentiometers for immediate HPF, LPF, and volume adjustments; DSP access for deeper, softwaredefined parameter control. Performance: 28/56bit processing precision for improved headroom and lower quantization artifacts in processed audio paths. Practical applications Small recording or rehearsal studios: Use as a compact frontend to feed multiple monitor mixes and apply basic filtering and gain staging before analogtodigital conversion. Fixed installations and multizone audio: Route two input sources to four zones with local volume and filter control while using DSP programming to optimize each output. Prototyping and audio development: Connect via ICP5 and SigmaStudio to test custom processing algorithms, tune conversion settings, and iterate quickly on DSP designs. Why this unit solves common problems Consolidates gain staging, analog filtering, and routing in a single module to reduce cabling and extra gear. Provides immediate manual control for live adjustments and software programmability for precision tuning, addressing both quick fixes and long term optimization. Improves conversion and processing results by combining resolution DSP processing with the ability to SigmaStudio projects for specific source and output requirements. What to expect in use Straightforward physical control for loudness and filter shaping during setup and performance. SigmaStudio compatibility for developers and installers who need to tailor processing chains and conversion behavior via ICP5. Reliable preamp functionality to feed downstream devices with configured, processed signals. This unit is intended for audio professionals and installers who require a compact, programmable preamp with handson controls and DSP flexibility.
