    I N T R O D U C T I O N 1 Introduction The Sonifex S1 Mixer is a compact, low cost, fixed format radio on-air mixing console designed to cater for a wide and far reaching broadcast market. On the surface, it is simple and easy to use but it also has hidden layer of variety and flexibility for those who like to get into the heart of their products, tweak the engine so to speak.

  • Page 14: Superb Audio Quality & Unquestionable Reliability

    Flexible The S1 is a highly configurable unit and has been designed to be jumper free, allowing the user to alter the configuration quickly whilst still on air rather than having to take apart the unit armed with a pair of tweezers and a magnifying glass.

  • Page 15: Atmosphere

    Installation Notes Atmosphere The S1 mixer should be installed in an area which is not subject to excessive heat or cold. Also, you should avoid installing it in atmospheric conditions which are dusty, smoky, or dirty, or where there is moisture or vibration. Do not use any liquids to clean the fascia of the mixer: a soft dry brush is ideal.
