Networked Audio Production System
Getting Started
CONNECTING THE SURFACE TO THE CORE
The Summa surface requires fibre
connections to the core via singlemode
or multimode LC SFPs. For a
redundant system two connections
are required, primary and secondary.
In the diagram on the next page the
primary connection is the solid line
and the secondary connection is the
dashed line. If you are running a
non-redundant Summa 128, only the
primary connection is required and the
cards on the right of the core will be
replaced by blanking plates.
Calrec do not provide interconnecting
fibres/cables, as the length, type and
quality will vary for each installation.
SFPs can be supplied with your Summa
system if specified at the time of order.

For more information on fibre and
different connection types please see
“Connection Information” on page 45.
The two control surface connections are
located on the back panel next to the
PSU unit and below the XLR connectors.
The left hand SFP, when viewed from
the back of the surface, is the primary
connection and on the right is the
secondary connection.
In the processing core, the left hand
Control Processor is the primary, the right
hand is the secondary.
A fibre connection should be fitted
between the primary surface connection
and the primary Control Processor’s
‘Surface 1’ connector. Unless a non-
redundant system has been chosen,
a backup connection should be fitted
between the secondary surface
connection and the secondary Control
Processor’s ‘Surface 1’ connector for
redundancy.
Note, the ‘surface 1’ connection is labelled
‘MAC 7’ on some control processor
models.
It is important to ensure that these
connections are made correctly - primary
to primary, secondary to secondary and
using the correct fibre SFPs.
