Open architecture platform
At the core of the AP series is a powerful open architecture DSP platform. This design philosophy allows users to flexibly drag and drop required processing modules to design the signal architecture from scratch. The signal nodes and flow mode are completely decided by the designer, rather than being locked by fixed firmware, which dramatically improves the flexibility of signal routing.
Maximum 12 channels independent AEC
AP series support up to 12 independent channels AEC algorithm processing, eliminating the tail for a long time up to 512ms, to meet the need for multi-channel AEC algorithm requirements.
128 channels Dante
AP series Dante version supports a maximum of 128 Dante (64x64) network audio transmission, both transmission and expansion become more flexible.
Variable channel version
AP series has a variable channel version, the device supports 8 variable fixed analog channels, specifically defined by the user is an analog input or output channel, can be configured in real time in the control software.
Web terminal customized user interface control
Users can design a customized control interface and upload it to the device. End users simply need to be on the same LAN and access the device's IP address via a browser to view the designed interface. This programmable audio DSP approach requires no application downloads for control, whether from a PC or a wireless mobile terminal.
Next-Gen Processing
Dual ADI SHARC 21569 @1GHz: Utilizing the massive computing power of dual-core ADI SHARC 21569 SIMD processors, the AP series handles complex FIR filters and logic modules with ease, ensuring zero-latency high-fidelity audio.
In a sophisticated Pro-AV environment, the AP Series Open Architecture DSP acts as the intelligent "brain," orchestrating the entire signal flow over the network. By leveraging AoIP (Audio over IP) standards, it ensures seamless interoperability across various endpoints.
How the Networked Ecosystem Works:
Audio Input Stage: The system receives high-fidelity digital streams from Dante Gooseneck Microphones or analog sources. Thanks to the 12-channel independent AEC, every voice input is crystal clear and free of echo.
Intelligent Processing: Once inside the Open Architecture platform, signals are processed through user-defined logic modules. You can drag and drop FIR filters, compressors, and auto-mixers to tailor the sound specifically for the venue's acoustics.
Network Distribution: The processed audio is then routed through the 128-channel Dante network with ultra-low latency.
Final Output: High-quality signals are delivered directly to Dante Amplifiers or PoE speakers, completing a fully networked, software-controlled audio loop.
System Designer’s Benefit: This interconnected approach eliminates complex analog wiring, reduces potential points of failure, and allows for complete system reconfiguration via software—no hardware changes required.
The primary difference lies in design flexibility. A Fixed Architecture DSP has a pre-determined signal path and a set number of processing modules (like a fixed mixer or EQ). In contrast, our Open Architecture DSP (AP Series) allows engineers to design the signal chain from scratch. You can drag, drop, and wire processing modules—such as FIR filters, AEC, and logic gates—in any configuration, limited only by the massive processing power of the ADI SHARC 21569 chip.
The AP series is built for high-capacity integration, supporting up to 128 channels (64x64) of Dante network audio. This high channel count, combined with ultra-low latency, makes it the ideal hub for large-scale distributed audio systems, such as university campuses, multi-floor corporate offices, and international airport terminals.
Programming is handled through our intuitive PC-based software, which supports one-click module alignment and channel auto-connection. For end-users, the AP series features a customizable Web UI. You can design a bespoke control interface and upload it directly to the device; users can then control the system via any standard web browser on a PC, tablet, or smartphone without downloading an app.
Absolutely. The AP series supports up to 12 independent channels of high-performance AEC. With a tail length of up to 512ms, it effectively eliminates echo in complex acoustic environments, ensuring seamless integration with platforms like Zoom, Microsoft Teams, and high-end hardware video conferencing systems.
