Communications connections

Communications connections are only made to other Meridian equipment.

The following sections describe the major points.

To connect to other Meridian 500 Series equipment

1.Connect one of the COMMS sockets on the rear panel of the 518 to one of the COMMS sockets on another 500 Series unit, using the 500 Comms lead supplied.

2.Connect all the 500 Series products together in this way to form a chain (not a loop). The order in which they are connected is not important.

If the system is to operate in 500 mode, then, configure the units with the following automatic setup procedure.

1.Switch all the units to Standby.

2.Press Clear on the handset. Each unit will display:

Auto

One unit will then be designated as the controller and display:

Con

All the other units will be configured as non-controllers and display:

NCon

The system is now set up and ready to use.

If for any reason the automatic setup does not give the configuration you want, you can restore the default operation by selecting a Type or by setting the controller status in Config as described on page 21.

Connecting to Meridian Digital speakers

1.Connect the phono plug on the end of the M-lead to the digital output of the 518.

4.Connect one of the two DIN plugs on one end of the M-lead to one of the COMMS sockets on the back of 518.

Note There are usually two DIN plugs on an M-lead. Take care to chose the correct one and do not force the plug. The second plug is used to connect to any 200 Series products in the range.
