The JetStream Mini is an integrated console engine and IP based audio networking platform. It handles console functions as well as audio networking duties throughout the station. It’s a powerful platform that utilizes space effectively and is easy to implement. Logitek continues to deliver on its promise of advanced design at affordable pricing.
The JetStream Mini provides audio I/O, mixing, processing, routing, and other functions. It may be operated via any Logitek control surface.
JetStream products represent the future of IP-based networked audio routing systems, providing ultra-fast audio streaming for on-air and production operations. Unlike the older versions of IP audio systems, JetStream takes advantage of new network protocols that make the system extremely easy to set up, administer and use.
Only the names of the channels need to be entered. The JetStream will acquire all necessary addresses, advertise its shared channels and make a list of sources offered by other JetStream units on your network. You don’t need a degree in computer science or even patience and coffee to set it up. With low power consumption, fanless convection cooling and high I/O density at an affordable price, the JetStream is ideal for radio studios and other applications.
