DIGISYN DLR-04 AES67 Module
DLR-04 Module series
The DLR-04 AES67 audio network module supports up to 4x4 channels with exceptional cost-effectiveness, low power consumption, and low operating temperature. It integrates seamlessly into compact audio devices like microphones, speakers, and small-channel audio products. Key features include ultra-low latency, uncompressed audio transmission, reduced power usage, plug-and-play operation, and shortened boot time. Its pinout design is compatible with certain manufacturers' Dante Ultimo interfaces, enabling effortless integration of audio products into existing AES67 audio local area networks without modifications.
