USB/RS232 Audio Switcher

Taking an external news feed or switching any other stereo audio source “to air” can often require expensive rack-mounted hardware.  Not any more – My USB/RS232 Audio Switcher is a simple and cost-effective solution to having feeds like Sky News, outside broadcasts and other sources routed to air via a command from your playout system.

The box reacts to serial strings which makes it possible to control from most playout systems – Macros supported include: On, Off and Timed.  The Timed function enables the audio switch for the duration specified.  The unit is the same size as my USB Fader Start Interface.


  • Connects to computer via USB (for control and power)
  • RS232/Serial Port interface for control: On, Off, Timed
  • Stereo audio switch – or can work in dual-mono mode
  • 6.35mm balanced sockets for audio input+output
  • 3x phono sockets for direct on/off toggle
  • Control from mAirList, Myriad, StationPlaylist Studio, RCS Zetta etc
