DAB1 DISTRIBUTED AUDIO SYSTEM
Paging Connections
(see Figure 13)
The DAB1’s Paging connections allow connection of an audio input from a telephone system,
microphone preamp or other device to be distributed to designated Paging zones when triggered
by the C
ONTROL Input. (Paging must be configured in the Sonance Control Manager.)
When 5 – 24VDC is present at the DAB1 C
ONTROL IN terminals, all system zones set to ‘Allow
Paging’ as configured with the Sonance Control Manager will switch to audio from the P
AGE IN
jack. When the control voltage drops to 0VDC, audio in the zones will switch back to the select-
ed source component.

One gold-plated mono RCA jack. Designed for use with line-level audio input from a telephone system, micro-
phone preamp or other device to be distributed to designated Paging Zones when triggered with the Control Input. (‘Allow
Paging’ must be configured in the Sonance Control Manager.)

::
One gold-plated mono RCA jack. Sends the Paging audio signal to other DAB1s in a system using multiple
DAB1 controllers.
TTrriiggggeerr WWiirree::
Connect a 2-conductor non-shielded wire from the trigger voltage source on the Paging device to one
DAB1’s C
ONTROL INPUT terminal (see
Figure 12,
on page 16), and daisy-chain to the CONTROL INPUT terminals of all other
DAB1s in the system. (Use 20AWG wire for runs up to 500’; 18AWG wire for runs up to 1000’.)
RS-232 Connection (see Figure 14)
The DAB1’s RS-232 connection allows it to send or receive serial commands to or from other
components. The RS-232 connection uses a female DB-9 connector with the following pinout
configuration:
PPiinn 22 == RReecceeiivvee ((RR
XX
))
PPiinn 33 == TTrraannssmmiitt ((TT
XX
))
PPiinn 55 == GGrroouunndd ((GG
NNDD
))
Since different serial devices have different RS-232 connection configurations, consult the
documentation of the device you want to connect to the DAB1 to determine what cable/adapter
may be required.
RS-422 Port (see Figure 3, on page 10)
The RS-422 port allows the DAB1’s capabilities to be expanded in the future. At the time of this writing (05/07) the
RS-422 port was not active. Check www.sonance.com periodically for the latest information about this feature.
