Breakthrough Price: Only $10 per Unit! (MOQ > 500 units) Achieve professional-grade performance at 1/3 of the industry cost, saving OEMs 30% on hardware budgets.
We proudly introduce the DL-04V network AES67 audio transmission module, designed for professional audio and AV equipment to deliver stable, efficient 4-channel audio transmission. Based on advanced hardware architecture, it supports high sample rates and integrates network control functions, enabling OEMs to rapidly build smart conference systems, unified communication (UC) devices, and IoT audio terminals.
🚀 Core Highlights: Professional Audio, Flexible Integration
The DL-04V centers on 4-channel audio transmission, making it ideal for space-constrained devices:
- Multi-Channel Support: Flexibly configure network audio I/O channels (0-4 selectable), easily adapting to compact mixers and conference microphones.
- High-Fidelity Guarantee: MSB-first 32-bit sample format supports up to 192kHz sample rates, ensuring lossless audio transmission.
- Low-Latency Control: Integrated UART serial port and UDP network control protocols allow real-time management via text or binary commands, significantly shortening development cycles.
🛠️ Technical Details: Simplified Design, One-Click Configuration
The DL-04V features a compact package with a pin layout optimized for seamless audio and data flow.
Pin Description
The module provides 13 pins, including:
- UART Serial Port
- I2S Audio Interface (Supports Master/Slave mode)
- MUTE/RESET Control
- Power Management
Startup Logic: Upon power-up, the MUTE/RESET pin automatically executes a sequence: it pulls low to generate audio clocks, then switches high after 1 second to ensure noise-free (pop-less) output.
Flexible Audio Format Configuration
- Customizable Timing: Supports
leftJustifymodes (0/1/3). Parameters like sample rate and channel count are easily modified via GUI software or UDP commands. - Developer-Friendly: Pre-set serial parameters (115200 baud, 8 data bits) supporting both Text protocols (e.g., "get IP") and UDP binary protocols.
📱 Application Scenarios
- Professional AV Equipment: ST2110 & AES67 integrated conference systems and UC terminals.
- IoT Audio Systems: Secure enterprise solutions utilizing UDP network control.
- Rapid Prototyping: Reference designs support PoE/non-PoE power. Features a lightning-fast 2-second startup and LED status feedback.
