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. It can also be controlled via GPIO contact-closures from any hardware card/relay.
The unit is the same size as my USB Fader Start Interface and is designed for semi-pro installations that do not require (or have) a 19″ rack panel. The box is designed to be placed near a computer, limited by the length of the USB cable.
- Connects to computer via USB (for control and power)
- RS232/Serial Port interface for control: On, Off, Timed
- 6.35mm balanced sockets for audio input+output
- 3x phono sockets for direct on/off toggle (On, Off, On/Off/On/Off etc)
- Control from mAirList, Myriad, StationPlaylist Studio, RCS Zetta etc
- Ethernet connectivity planned for a future release
The following commands are supported via RS232/Serial from most playout systems:
- AUD0 : Turn audio off
- AUD1 : Turn audio on
- TAUDnnn : Turn audio on for nnn seconds, eg: TAUD122 will turn the audio on for 120 seconds (2min, 2sec) for a news feed
