The Central Station is the ultimate studio-monitoring interface for the modern digital studio. The Central Station features three sets of stereo analog inputs to switch between input sources such as: DAW, mixer, CD/DAT/Tapeplayer, or keyboards/samplers. Two stereo analog inputs feature TRS balanced and the third stereo input features RCA inputs with trim control for level matching of input signals. In addition, the Central Station will accommodate two digital inputs via S/PDIF or TOSLINK providing D/A conversion up to 24Bit/192kHz. This allows you to monitor DAW and CD/DAT outputs through the same professional quality converter for the most accurate A/B comparison and highest quality monitoring environment. The digital to analog converter offers the highest possible audio quality with over 117dB dynamic range and ultra high quality analog circuitry. The Central Station features three sets of monitor outputs, each with their own set of passive trim controls. The monitoring section also provides MUTE, DIM and MONO switches. In addition, the Central Station includes a set of CUE outputs that can feed headphone amplifiers and a separate stereo MAIN line level output.
