OCTOPUS ST SPLIT is 1U rack-mount 19” high quality audio stereo switcher equipped with one Main input, four Sub inputs and four outputs

The outputs gain may be varied with a potentiometer, and a led display the status of each output ( Main or Sub inputs).

The OCTOPUS ST SPLIT has one stereo balanced line input, five stereo balanced outputs; the XLR-3 input and outputs are electronically balanced each output is individually buffered so that a short circuit on one won’t affect the others.

OCTOPUS ST SPLIT can accept external controls normally off or normally on, steady or pulse; the inputs are opto-insulated and the configuration can be carried out with its panel.

OCTOPUS ST SPLIT supplies an opto-insulated output control which relays the status of the internal audio switcher.

The status of the output opto-coupler can be programmed, it can be normally on, off, steady or pulse.

OCTOPUS ST SPLIT is equipped with by-pass relay to ensure in any case the passage of the main signal in the face of power failure.
