NEMESIS ACS-1 AUTO SWITCHOVER
The Nemesis ACS-1 Auto Switcher is a 1U rack mount unit that automatically controls any of the Nemesis range of switchover units by detecting the presence of playback signals using either a 1 kHz tone or SMPTE timecode.
Designed primarily for live concerts, stage shows and theatre where backing tracks are used for orchestration, vocals and sound effects, this allows for 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)
Sources can be monitored using a traditional tone detection method, a fault being flagged when the tone disappears from a source, or a SMPTE timecode detection method.
The advanced timecode detection algorithm continuously monitors the frame position of each source and detects any frame errors or backwards jumps in running SMPTE, causing an error
state to be flagged. This prevents stuck buffers from frozen or crashed playback sources otherwise undetected in other systems using just the simple presence of a tone.
Also included in the unit is a standard Nemesis 5 pin remote input for connection to an external remote buttons, standard Nemesis 15-pin DSUB relay GPO for connection to Nemesis or other audio changeover units, MIDI output for control of MIDI based units and an optional dual redundant internal PSU.
