ARX Systems has released the Remote Switcher externally controlled stereo input signal switcher, for use in EWIS (Emergency Warning and Intercommunications System) emergency announcements, console switching, and remote control of signal sources in broadcast applications.

‘We developed the Remote Switcher in response to requests from integrators and installers for a unit allowing remote and external switching selection between two line level audio sources,’ says ARX MD, Colin Park. ‘EWIS is becoming mandatory for most new and upgraded commercial buildings and public spaces, and our Remote Switcher is a cost effective solution for noiseless and instantaneous switching between normal audio program and EWIS emergency announcements.’

The Remote Switcher silently switches between two pairs of A or B female XLR inputs to a stereo pair of XLR male output connectors. ARX SoftSwitch technology achieves this with no loud bangs through the audio system when switching. Input channel control can be selected in two ways – Mode 1 by remote switch/relay closure (using an external power pack/wall wart) or Mode 2 by 12-24V DC supplied from an EWIS panel or similar.

‘Further applications include remote switching between FOH or monitor consoles, main and DJ consoles, when one main loudspeaker system is being used, and also remote broadcast signal source and transmitter switching,’ Park adds.
