Important Notice.
The console has two earth posts on the rear connector panel. They are located

near to the power supply connectors. The un-insulated metal post is the chassis

ground, and the insulated post is the system ground. The console is supplied with

these two posts linked together. It is essential that the console is operated with

these two earths linked. They may, however, be linked at a different point in the

installation: for example, a technical earth in the installation site. In this case the

wire link between the two posts must be removed.

The meterbridge has a number of connectors as shown below:

The MONITOR/COMMS D-type connector routes signals to the Monitor Selector

PCB ( see the Meterbridge connector list on the previous page for pin details).
The ANCILLARY METERS D-type connector carries the Groups and Auxes into

the meterbridge. The actual connections used will depend on the number of ancil-

lary meters which are fitted. The connections are:

inputs here may be monitored on the Meters which are associated with the

Monitor Selector PCB.
There are also 2 additional XLRs: these are for future expansion.
