It provides completely variable control over the whole amount of compression taking place without having to alter numerous settings in order to do so.
  • Page 8 Temperature Led The S2 is at optimum temperature when the front panel LED indicator is lit, i.e. after the soft start and when the valves have reached optimum temperature - this may take a few seconds.
