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.
