Introduction
IMPORTANT:
The DAB-801 is for use with up to four 2-channel amplifiers or two 4-channel amplifiers. The DAB-801 does not support
8-channel amplifiers.
Thank you for your purchase of the DAB-801 Q-SysTM amplifier backup system. In order to insure correct operation in the unlikely event of amplifier or
Q-Sysfailure, we recommend you review all the information provided in this Installation Manual.
The DAB-801 extends Q-Sys backup capability to include designated QSC power amplifiers and I/O Frames populated with CODP4 cards. The
DAB-801 adds the ability to add N+1 amplifier redundancy to any system for up to 8 channels, as well as the ability to automatically switch all DataPort
connected amplifiers from a primary I/O Frame to a backup I/O Frame.
The DAB-801 is easily integrated into a Q-Sys based audio system. Mounted in the rear of a rack, the DAB-801 minimizes rack space consumption. AC
line connection is fast and easy; an IEC-style quick-disconnect with locking bracket ensures 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. Two D-Sub 15 pin connections allow direct connection to a pair of I/O Frames for control and monitoring
of the DAB-801. Two paging modes are available for high priority paging and are activated with either a standard contact closure or +12VDC trigger
voltage. Two DAB-801 panels may be combined using the included 37 pin cable for 16 total channels of I/O Frame and N+1 redundancy.
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.
Download the latest version of Q-Sys software to insure that your system will work with this accessory.
Glossary
AC Mains –The AC voltage present at a wall socket or outlet.
Backup –The redundant item in a fault-resistant system. If the primary item fails, the backup item replaces the primary item, restoring full
system operation.
CODP4 –QSC output card designed to mount internally in an I/O-Frame. Connects to 2 DataPort equipped amplifiers or a single
4-channel amplifier.
D-Sub (or DB) –A type of cabling connector whose outer shell is shaped like the capital letter D. DB type connectors have two individual
rows of pins.
DataPort –A proprietary QSC connection featured on many of our installation and touring amplifiers. Uses a HD-15 type connector.
Extension Panel –An identical DAB-801 that is connected to a master DAB-801 bringing the total system channel capability up to
16 audio channels.
Fault-tolerant –A system that continues operation, possibly at a reduced level, rather than failing completely, when some part of the system fails.
GPIO –An acronym that stands for General Purpose Input and Output.
HD15 –A high density type of cabling connector whose outer shell is shaped like the capital letter D. HD type connectors have three individual rows
of pins. The “15” indicates the total number of pins in the connector.
IEC Socket –A standard type of AC mains connector used in most consumer equipment.
I/O Frame –QSC hardware used to input and output audio signals from a Q-Sys system.
N+1 Redundancy –A system that has “N” items and a single backup item. If any single item fails, the system automatically replaces that item with the
backup. In the case of the DAB-801, amplifiers are redundant in this manner.
Primary I/O Frame –The main I/O Frame in a fault-resistant system. If the primary I/O Frame fails, the backup item will automatically restore full
system operation.
Q-SysTM –QSC Audio’s proprietary system solution.

How It Should Be Used
The DAB-801 must be used as part of a Q-SysTM system. As such the DAB-801 cannot be used with any other control system. Furthermore, the
DAB-801 interfaces to QSC DataPort equipped amplifiers only.
Every amplifier connected to the DAB-801 must be the same model; the DAB-801 does not support mixing amplifier
models.
Rack Mounting
• The DAB-801 mounts in the rear of a rack. Use four screws and washers to mount the DAB-801 to the rear rack rails. The DAB-801 can be mounted
in the front of a rack, however QSC does not recommend this as it complicates the routing of wire and cable.
When Mounting in a Rack Please Note:
1. Elevated Operating Ambient –If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the
maximum ambient temperature (Tma) shown under Specifications.
2. Reduced Air Flow –Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equip-
ment is not compromised.
3. Mechanical Loading –Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven
mechanical loading.
4. Circuit Overloading –Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of
the circuits might have on over current protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
5. Reliable Earthing –Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connec-
tions other than direct connections to the branch circuit (e.g. use of power strips).
AC Mains
Connect AC power to the IEC socket on the front of the panel by locating the IEC
connector-end of the AC power cord and inserting it fully into the IEC socket on the panel.
Swing the metal retention clip up and over the end of the IEC cable to ensure that the
cable is not inadvertently disconnected.
If the cord supplied by QSC becomes lost or damaged, a replacement 18
gauge IEC power cord may be used.
The DAB-801 does not have a power switch to ensure high reliability.
Caution: Lethal voltages are present in an AC outlet.
AC Mains Disconnection
To remove the AC mains cord, unlatch the metal retention clip and grasp the IEC connector’s plastic body. Pull straight out, removing the connector
from the socket.
