4. Operation
4.1. Connectors/Cabling
The i5 MP is supplied with a Phono (RCA) and European Pluggable type connectors,
for both balanced and unbalanced operation. The Phono plug is used for unbalanced
operation, and the European type can be used for both balanced and unbalanced
operation. The unit is powered via an IEC mains socket. See Figure 4a.
When shipped, the unit is set for unbalanced operation. For this, the European type
plug must be connected with pins 1 and 3 linked. Us e shielded single conductor cable
and simply plug a phono connector into the phono socket. Alternatively, if the
European pluggable type plug is used, wire the positive wire to pin 2 and the ground
wire to pin 1 and leave the link in place.
For balanced operation, use twin conductor shielded cable (microphone cable) and
wire the European pluggable type connector as shown in the chart below:

4.2. Powering
Before connecting th e i5 MP to a mains inlet socket, ensure all other connections are
correctly made. The i5 MP may be supplied with an IEC mains cable. Connect this
cable into the IEC mains socket on the back of the unit. If a cable is not supplied, use
an IEC mains cable wi th the correct plug and rating for your country.
The i5 MP is designed to be powered continuously, but we recommend it is
disconnected from the mains if it is to be left unused for a considerable period of time.
An all
pole mains switch with a contact s eparation of at least 3mm shall be
incorporated in the electrical installation of the building.
