Q-SYS™ Amplifier and I/O Frame Backup Accessory


  • One DAB-801 unit can provide N+1 instantaneous two-channel switchover redundancy for as many as eight amplifier output channels
  • Two DAB-801 units can be cascaded to provide two- or four-channel switchover redundancy for up to 16 amplifier output channels
  • Automatic detection and switchover between inputs from primary and backup I/O Frames, in case of failure upstream
  • Fault tolerant control and monitoring of each DAB-801 is available using simultaneous GPIO terminals connected to both primary and backup I/O Frames
  • Two additional non-networked analog “high line” level inputs provide emergency evacuation signal which can override all other input signals
  • QSC DataPort connectors and high-current terminal blocks for easy and reliable installation
  • Q-SYS technical support is available 24/7 worldwide
