9.3 Connectors
9.3.1 Introduction
This section gives an overview of typical system 
connections using the multi channel interface.
Connecting to the basic amplifiers (see section 9.3.2).
Connecting to the network (9.3.3).
Connecting the multi channel interface by-pass (see 
section 9.3.4).
Connecting the control inputs (see section 9.3.5).
Connecting the control outputs (see section 9.3.6).
9.3.2 Connecting to the basic amplifier
The double amplifier connectors 1 to 14 are used for the 
basic amplifier channels. The double amplifier 
connectors 15 and 16 are available for two spare basic 
amplifier channels.
The connection to the basic amplifier is made with two 
modular (RJ45) connections. 
The connections of the basic amplifier and the multi 
channel interface have a triangle (top row) and a circle 
(bottom row) symbol. 
1 Connect the triangle symbol connector of the multi 
channel interface to the triangle symbol connector of 
the basic amplifier.
2 Connect the circle symbol connector of the multi 
channel interface to the circle symbol connector of 
the basic amplifier.
 
9.3.3
Connecting the network
Use the system bus connectors and LBB4416 network 
cables to connect the multi channel interface to the 
Praesideo system. Both connectors are interchangeable.
Normally the multi channel interface receives its power 
from the connected amplifiers. This is the 
recommended setting, but if it is not connected to an 
Caution
Do not connect the circle symbol connector of 
the multi channel interface to the triangle symbol 
connector of the power amplifier.
Caution
Do not connect the modular (RJ45) connectors 
to any Telecom or Ethernet network. These 
connectors are dedicated for the multi channel 
interface and the basic amplifiers only.

Caution
Always use CAT-5 modular plugs with an empty 
connector crimp part (refer to figure 9.3, part A). 
Some (pre-)assembled CAT-5 modular plugs 
have a connector crimp part that is filled with 
plastic (refer to figure 9.3, part B). These 
connectors do not give a reliable connection to 
the modular (RJ45) connectors on the basic 
amplifiers and multi channel interfaces and can 
therefore cause unexpected fault events.
