Outline Specifications
PRELIMINARY MERIDIAN C SERIES
The C61R can be configured with a
powerful Windows graphical set-
up application (downloadable from
the Meridian web site), which allows
access to all the unit’s functions and
configuration.
However, the C61R can also be
configured extensively from the front
panel, thanks to the comprehensive
‘soft-key’ based user interface like
that employed on Meridian’s G Series
components. ‘Wizards’ lead you through
the configuration procedure, allowing
a powerful degree of customization
without having to hook up a computer.
The C61’s firmware can be updated
via serial link with files downloaded
for the Meridian web site. Two serial
connectors are provided: one on the
rear panel for integration into industry-
standard home automation systems,
and one on the front panel allowing
rapid access for computer-based system
reconfiguration. A rear panel USB port
is also provided that can be used for the
latter application.
