Supports control via Sigmastudio, APP, or PC UI for flexible, userfriendly setup and tuning. Multichannel power 4x30W output delivers strong, clear sound across multiple speakers or zones, suitable for compact home theaters, DIY projects, and small venues. External potentiometer allows realtime adjustment of audio system parameters during setup or operation, enabling onthefly tweaks without software. Integrated ADAU1701 DSP chip Fcio provides builtin signal processing for precise EQ, dynamics, routing, and crossover tasks, reducing external hardware needs. Integrated Bluetooth 5.0 enables wireless streaming and control, improving convenience and reducing wire clutter. Compatibility and control Works with Sigmastudio for professional DSP design and calibration. Compatible with APP and PC UI for convenient, everyday adjustments from mobile devices or a computer. Internal DSP (ADAU1701) handles processing, freeing external gear from heavy computational load. Key specifications and features Output: 4 channels, up to 30W per channel (4x30W) DSP: Integrated ADAU1701 DSP chip Bluetooth: Bluetooth 5.0 integrated Control methods: Sigmastudio, APP, and PC UI Adjustment: External potentiometer for audio parameter control Use scenarios Home audio upgrade: add DSP processing to a bookshelf or floorstanding speaker system, stream music via Bluetooth, and tune the sound with Sigmastudio or mobile app for a balanced, roomaware result. Small venue or stage monitor setup: drive multiple speakers with reliable amplification (4x30W) while using Bluetooth for background music or wireless control, and finetune audio with the external potentiometer during setup or performance. DIY speaker project: implement precise crossover, EQ, and dynamic processing with the ADAU1701 DSP, adjust parameters via the external potentiometer, and connect via Sigmastudio or PC app for iterative tuning.
