DAB-801
Q-Sys™ Amplifier and I/O Frame Backup Accessory
Features
• One DAB-801 unit can provide N+1 instantaneous 2-channel
switchover redundancy for up to 8 amplifier output channels
• Two DAB-801 units can be cascaded to provide 2 or
4-channel switchover redundancy for up to 16 amplifier
output channels
• Automatic detection & switchover between inputs from
Primary and Backup I/O Frames, in case of failure “upstream”
• Fault tolerant control & 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 & reliable installation
• Q-Sys technical support is available 24/7 - worldwide
The purpose of the DataPort Amplifier
Backup Panel is to provide redundancy,
emergency paging, and other functionality
required for many Life-Safety & 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.
Two D-Sub 15 pin connections allow direct
connection to a pair of Q-Sys I/O Frames for
full control and monitoring of the DAB-801
through the Q-Sys Designer software. All
primary amplifiers are continuously
monitored by Q-Sys along with the power-on
status of the backup amplifier. Periodic full
tests of the backup system can be
programmed to ensure signal integrity and
meet regulatory requirements.
Additionally two analog “high line” level
inputs allow for direct connection of a
carbon-type microphone, or a linelevel
pre-recorded message for emergency
evacuation paging which can then override
all other input signals. A normal low
impedance paging microphone may also be
connected with the addition of an external
microphone preamp.
Using these analog inputs, each DAB-801
has two priority modes, Alarm and Page.
The Alarm input overrides all other signals,
and is used for major emergencies. The
Page input overrides all signals except the
Alarm input, and can be used for other
announcements. These inputs can be
assigned to any combination of amplifier
channels, and can be activated with either a
standard contact closure or +12VDC trigger
voltage from the fire alarm panel.
The DAB-801 is easily integrated into a
Q-Sys based audio system. Mounted onto
the rear of a rack, the DAB-801 minimizes
rack space consumption. AC line
connection is fast and easy with an IEC
style quick-disconnect and locking bracket
to ensure reliable AC mains connection. A
one world power supply operates on
100-240VAC, 50/60Hz.
By using QSC standard HD-15 DataPort
connectors and high current detachable
terminal blocks, the DAB-801 provides an
easy to install connector set.
Various LED indicators alert the user to
current panel status. The LEDs include an
AC power indicator, I/O Frame power status
indicators, amplifier power status indicators,
I/O Frame failure indicators, and amplifier
failure indicators.
Each DAB-801 connects up to eight
loudspeaker circuits, which may also be
100V transformer isolated.
