DIGISYN DL-04V AES67 Module



DL-04V Module series
The DL-04V is a high-performance RISK-V audio networking module that supports both the AES67 and SMPTE ST 2110-30 protocols. It supports up to 4x4 channels and a 192kHz sampling rate, offering exceptional cost-effectiveness, low power consumption, and low operating temperature.
The DL-04V offers an exceptional economic advantage, priced at just $10 per module. This highly competitive cost makes professional-grade audio networking accessible even for compact and budget-conscious product designs. Despite its low price, the module delivers full performance without compromising on features, allowing manufacturers to integrate high-quality, standards-compliant audio networking into their devices at an unprecedented value. This affordability significantly lowers the barrier to entry for developing IP-based audio products, enabling more competitive market positioning and faster adoption in cost-sensitive applications.
With support for ST 2110-30, the module enables devices to seamlessly connect to SMPTE ST 2110 IP media networks, which are widely used in professional broadcast and live production environments, ensuring precise synchronization and transmission of audio streams. Furthermore, its pinout design is compatible with certain manufacturers' Dante Ultimo interfaces, allowing for effortless integration of audio products into existing AES67 or ST 2110 audio local area networks without modifications.
