The Studer OnAir 1000 brings reliable digital technology and the proven Touch-n-Action operating concept of the Studer OnAir 2000 to a lower-priced segment of the market.

Studer’s patented Touch-n-Action graphical user interface makes the Studer OnAir 1000 unique in its class. Mixer settings can be personalized and stored for each operator. Management of user access rights reduces the risk of human error during production and live transmission. The Studer OnAir 1000 is available in two different versions, one for predominantly analog environments, the other for predominantly digital environments. The mixer is equipped with 10 channel faders and 2 master faders which retain the most important operating elements and adjacent readouts.

The mixer’s standard features are impressive and include a comprehensive monitoring section, 2 analog inserts, a serial interface, GPIO, and more. Professional integration into a radio automation system therefore is an easy task. In addition to a mains input, the console is fitted with a separate socket for 24 V DC, which can be used together with the mains.

The attractively designed Studer OnAir 1000 was developed for production and live broadcasting in both network and local radio stations.
