10.3 Connectors
10.3.1 Introduction
This section gives an overview of typical system
connections with the multi channel interface and
loudspeakers.
• Connecting the mains (see section 10.3.2).
• Connecting the multi channel interface (see
section 10.3.3).
• Connecting to ground (see section 10.3.4).
• Connecting the amplifier channels (see
section 10.3.5).
• Connecting the local audio input (see section 10.3.6
• Connecting the back-up power supply (see
section 10.3.7)
10.3.2 Connecting to the mains
Proceed as follows to connect the basic amplifier to the
mains:
1 Select the correct local mains voltage using the
voltage selector on the rear of the basic amplifier (see
table 10.1).
2 Put the correct type of fuse in the basic amplifier.
The fuse is in the mains inlet. Note that the same
fuse value is used for both voltage ranges.
3 Connect the mains cord to the basic amplifier.
4 Connect the mains cord to a locally approved mains
outlet.
The mains supply can be supervised by the basic
amplifier (see figure 10.2, no. 9) and is available for the
multi channel interface.
10.3.3Connecting to the multi channel
interface
The connection to the multi channel interface (MCI) is
made with two Ethernet connections. The MCI
connections have a triangle and a circle symbol (see
figure 10.5).

Caution
Do not connect the circle symbol connector of
the multi channel interface to the triangle symbol
connector of the power amplifier.
Caution
Always use CAT-5 modular plugs with an empty
connector crimp part (refer to figure 10.4, part
A). Some (pre-)assembled CAT-5 modular plugs
have a connector crimp part that is filled with
plastic (refer to figure 10.4, part B). These
connectors do not give a reliable connection to
the Ethernet connectors on the basic amplifiers
and multi channel interfaces and can therefore
can cause unexpected fault events.
