Dante Broadway

The Dante Broadway chip delivers Dante networking for medium channel-count applications at a breakthrough price-to-performance ratio, ideal for small mixers, power amplifiers and conferencing solutions.

Offering significant performance enhancements over the low channel-count Dante Ultimo solution, Dante Broadway delivers up to 16x16 channels of audio at 96kHz in an affordable, compact chip. Latency can be as low as 0.25ms on Gigabit Ethernet, and redundancy is supported in specific configurations for high-availability applications.

Dante Broadway provides a perfect blend of performance, features and economy for mid-tier products such as multi-channel amplifiers, smaller DSP units, hardware interfaces and compact mixing consoles.

Dante Broadway blends the small form factor of our popular Ultimo products with the most popular features of the powerful Brooklyn II module, including latency as low as 0.25ms and support for Gigabit Ethernet.
