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:

1Select the correct local mains voltage using the voltage selector on the rear of the basic amplifier (see table 10.1).

table 10.1: Voltage selector and fuse

Selector	Mains voltage	Fuse
	V(AC)
115	100 - 120	T6.3A H 250V
		(IEC 60127 or UL 248)
230	220 - 240	T6.3A H 250V
		(IEC 60127)

The mains supply can be supervised by the basic amplifier (see figure 10.2, no. 9) and is available for the multi channel interface.

10.3.3 Connecting 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.

2Put 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.

4Connect the mains cord to a locally approved mains outlet.
