Comprehensive but never confusing, the Zone 4 will quickly become the core of your audio system. 

The state-of-the-art Zone series from Optimal Audio was created with one core goal in mind - unparalleled control and flexibility in a user-friendly package that is accessible even for those with little experience of managing audio systems. All at a surprisingly affordable price!

The Zone 4 offers groundbreaking audio signal routing and processing and is designed as a pre-amp unit to be connected to your existing power amp. Easily combine audio sources (such as streaming services, phones/tablets, radio, computers, TVs, etc) to create separate mixes in up to four separate zones. And with a large, clear and fully labellable interface on the front of the unit and modern LED dials, you'll never need to second-guess a setting or zone again.
