ACS-PLUS Stereo Auto Switch

The Nemesis ACS-PLUS Stereo Auto Switch is a 1U rack mount unit that automatically switches between two stereo audio signals using XLR3 balanced cables, by detecting the presence of playback signals using either a 1 kHz tone or SMPTE time code.

Designed primarily for live concerts, stage shows and theatre where backing tracks are used for orchestration, vocals and sound effects, this allows you to set up a redundant backup system which automatically switches between two sources should a failure of one of the sources occur. There are 2 modes of operation:

  • Comparison (switches from A to B if input signals differ)

  • Signal Loss (switches from A to B if signal lost on A)

The Time Code detection detects any change in forward direction timecode or frame errors. This prevents stuck buffers from frozen or crashed playback sources otherwise undetected in other systems using the simple presence of tone system.

Also included on the unit is a MIDI output for use with MIDI controlled audio switchers.

Key features:

  • Switches balanced stereo audio (2 into 1)

  • 2 modes of operation: Comparison (switches from A to B if input signals differ) Signal Loss (switches from A to B if signal lost on A)

  • Detects either 1Khz tone or valid running SMPTE

  • SMPTE detection detects any change in forward direction timecode or frame errors. This prevents stuck buffers from frozen or crashed playback sources otherwise undetected by the simple presence of tone.

  • MIDI output for control of MIDI based units such as RME MADI Bridge

  • Large 16×24mm A B front panel buttons to select source
