Introduction
IMPORTANT:
The DAB-801 is for use with up to four 2-channel amplifi ers or two 4-channel amplifi ers. The DAB-801 does not support
8-channel amplifi ers.
Thank you for your purchase of the DAB-801 Q-Sys
TM
amplifi er backup system. In order to insure correct operation in the unlikely event of amplifi er or
Q-Sys
failure, 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 amplifi ers and I/O Frames populated with CODP4 cards. The
DAB-801 adds the ability to add N+1 amplifi er redundancy to any system for up to 8 channels, as well as the ability to automatically switch all DataPort
connected amplifi ers 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, amplifi er
power status indicators, I/O Frame failure indicators, and amplifi er 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 amplifi ers or a single
4-channel amplifi er.
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 amplifi ers. 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, amplifi ers 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-Sys
TM
–
QSC Audio’s proprietary system solution.
