The purpose of the DataPort amplifier backup panel is to provide redundancy, emergency paging, and other functionality required for many life-safety and evacuation or mission-critical audio systems.
The DAB-801 extends the Q-Sys fault-tolerant backup capability to include any QSC DataPort power amplifier and I/O Frames populated with Q-Sys DataPort cards. The DAB-801 provides the ability to add true N+1 amplifier redundancy to any Q-Sys system, plus the ability to automatically switch amplifier input sources from a primary I/O Frame to a backup I/O frame.
A single DAB-801 supports four 2-channel primary amplifiers with one 2-channel backup amplifier or two 4-channel primary amplifiers with one 4-channel backup amplifier. Two DAB- 801s can be stacked to provide double the primary amplifier redundancy.
- 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
