DL-MAX: 128×128 Channels, Native Support for AES67 and ST 2022-7 Redundancy

In the professional audio-visual integration field, Dante network audio modules have long been the default choice for many equipment manufacturers. However, high licensing costs and limited customization flexibility are increasingly becoming shackles to product innovation. Now, a more open, high-performance, and cost-effective alternative has matured.

The DL-MAX 128-Channel Mini-PCI AES67 Network Audio Module is designed for OEM/ODM manufacturers seeking a breakthrough. It not only matches or even surpasses mainstream solutions in channel density and performance but also offers direct hardware replacement feasibility for Dante Brooklyn II/III modules, while natively supporting advanced network features like ST 2022-7 redundancy. It is the ideal core for building the next generation of open, highly reliable professional audio equipment.

🚀 Core Advantages: Open, High-Density, Seamless Replacement

DL-MAX aims to help you break free from vendor lock-in and achieve top-tier performance with a lower Total Cost of Ownership (TCO).

• Dante Modules Compatibale: The DL-MAX adopts a standard 124-pin Mini-PCIe interface form factor and similar physical dimensions, providing a direct hardware replacement path for existing designs based on Brooklyn II or III modules. You can migrate from a proprietary protocol to the open AES67 standard ecosystem without a complete motherboard redesign, significantly reducing hardware iteration risks and development costs.
• Native AES67 & Open Ecosystem: The module natively supports the industry-standard AES67 protocol, ensuring seamless, license-free interoperability with all AES67-compliant audio equipment on the market. This opens a wider door for your product's system integration.
• Supports ST 2022-7 Seamless Redundancy: To meet the extreme reliability requirements of mission-critical applications like broadcasting and live events, DL-MAX supports the ST 2022-7 redundancy protocol. This feature allows audio streams to be transmitted via two independent network paths, enabling sub-millisecond seamless switching in case of a primary path failure, eliminating audio interruption caused by network single points of failure and building a rock-solid audio network.
• Doubled Channel Density & Cost Advantage: At a 48kHz sample rate, a single module provides bidirectional transmission capability of up to 128×128 channels, offering highly competitive channel density. Combined with its open architecture, it can help you reduce core audio I/O hardware costs by over 30%.

🛠️ Technical Specifications: Designed for Professional Integration and Redundancy

While delivering exceptional audio performance, the DL-MAX's design fully considers the integration needs of high-reliability systems.

• Professional Audio Core: Supports 48k/96k/192kHz sample rates and 16/24/32bit sample depths, ensuring broadcast-quality audio. Network transmission latency is configurable, as low as 1ms.
• Redundancy & High-Reliability Networking: In addition to supporting the ST 2022-7 redundancy protocol, the module's network audio receive streams can handle up to 128 unicast streams and 4 multicast streams, providing a solid hardware foundation for complex network audio routing and redundancy backup.
• Flexible Audio Configuration: Audio formats are fully configurable via software, including sample rate, channel count (up to 128), channels per data line (2/4/8/16), and multiple leftJustify timing modes, ensuring perfect interfacing with various external ADC/DAC or DSP chips.
• Dual Control Interfaces: Provides both UART serial port and UDP network control interfaces. Developers can query device status via simple text commands or perform in-depth control and network passthrough via the UDP protocol, enabling flexible device management.

⚙️ Why Choose DL-MAX Over Dante Modules?

1. Eliminate Licensing Fees: By adopting the open AES67 standard, you avoid expensive annual licensing fees or per-port charges, resulting in a clearer, more competitive long-term product cost structure.
2. A More Open System: It can interconnect with any third-party device supporting AES67, breaking down the barriers of proprietary protocols and giving your end customers greater freedom in equipment selection.
3. Customizable Functionality: The underlying protocol is open, allowing you to develop unique control functions, monitoring interfaces, or optimization algorithms for specific applications (e.g., conferencing, broadcasting, public address), creating product differentiation.
4. Native High Reliability: Support for ST 2022-7 redundancy is a built-in feature for mission-critical applications, not an extra-cost add-on, helping you easily build equipment that meets broadcast-grade reliability requirements.

🎯 Typical Application Scenarios

• Digital Mixers & Audio Processors: Directly replace existing Dante modules to gain higher channel counts and open interoperability at a lower cost, while meeting the network redundancy demands of live events.
• Professional Conferencing Systems: Build AES67-capable conference hosts with redundancy backup to ensure zero interruptions in large, important meetings.
• Broadcast Playout & Master Control Systems: Serve as the core of audio embedders, distributors, or interface boxes, seamlessly integrating into IP-based production workflows based on ST 2110 and AES67, and complying with ST 2022-7 redundancy specifications.
• Public Address & Paging Systems: Construct highly reliable, easily scalable IP broadcast network infrastructure.
