Important Information
a/b-Audiobox - Operation Guide - V03 10/2020 7
Important: Improper use may cause, for example, functional restrictions or
malfunctions, the destruction of the device or, in a worst-case scenario, per-
sonal injury.
• If you are still uncertain about how to use the product properly after
reading the section below, please contact your specialised dealer.
The a/b-Audiobox is an adapter for transferring low frequency signals over an
analogue telephone line.
With the a/b-Audiobox you can connect a sound system to the internal a/b port
on a PBX, for making loudspeaker announcements from the internal tele-
phones. It also includes a switch contact with which the sound system's loud-
speaker zone can be changed.
You can install up to six switchable a/b switching modules, available as acces-
sories, between the PBX and a/b-Audiobox to implement additional switching
functions.
The a/b-Audiobox can be combined with all Auerswald PBXs, providing a way
to connect analogue DTMF telephones. It is also possible to connect it to PBXs
from other manufacturers, but you should verify this in advance, by checking
with the specialist supplier or the manufacturer.
You can program the a/b-Audiobox from a telephone on the PBX, and so con-
figure it to meet the special needs of the particular environment.
The a/b-Audiobox is only suitable for use indoors.

In this chapter you can find out how to connect the a/b-Audiobox to a PBX and a sound sys-
tem. It also describes how to connect and configure the a/b switching modules (which are not
included in the scope of delivery).
Connecting a Sound System
Warning: Touching live terminal clamps or power cables can cause life-
threatening electrical shocks.
• Disconnect the connection to the telephone connection on the PBX
before you carry out any work on the device.
• Ensure that any tools you use on live cables are sufficiently insulated.
• For the connection to the PBX, also note the safety information in the
manual for your PBX.
Warning: Power surges, which may occur during electrical storms, can
cause life-threatening electric shocks, or damage or destroy the connected
PBX.
• Arrange for a qualified electrician to lay all the cables inside the building.
• Do not connect or disconnect power cables during an electrical storm.
Note: For more information about the contact assignments, also refer to the
manual for your PBX.
You will find information about the connections for extending the switching
functions below.
Always install the cables for connecting to the a/b ports separately from
other power lines. This will avoid the creation of a disruptive humming noise
during the announcement.
