8. Managing Partitions and Signal Types
Setting Up Mono Signal Switching
Routing Mono Signals
Successful mono routing relies heavily upon the router control system and how mono channel par-
titions are configured. It is usually desirable to implement routing to allow any input channel to
route to any output channel. However, depending on how the routing is configured, the creation of
every possible combination can cause the router control system database to nearly triple in size.
To help you configure the most efficient mono routing for your needs, three possible options are
presented:
• Mixed stereo and mono
• Mono only
• Mono only using two partitions
Status Display Issues
When a device is configured as both mono and stereo, the router control system interface may not
display status correctly. The router control system can have different sources routed to its left chan-
nels and right channels. When in stereo mode, the router control system reports status for only one
channel, typically the left channel (i.e., as a single channel pair). As a result, there may appear to be
a destination status error when viewing a destination configured for both stereo and mono operation
simultaneously.
Several iterations of each device connected to the router control system must be built. At least two
are required: one on the stereo partition and one on the mono partition. Depending upon the options
available for channel swapping within the router control system, two entries for each device may be
required on the mono partition.
Matrix partitions may overlap. When a device is configured such that it utilizes overlapping parti-
tions, the router control system interface may receive two possible values for source ports for a
given destination port (left and right). Behavior with third party control systems cannot be pre-
dicted. It is recommended that you test for this issue before placing the system into service
Option 1: Mixed Stereo and Mono Mode
A mixed stereo and mono mode is used when it is necessary to have stereo 2-channel routing in
some areas (e.g., a dubbing room) and mono channel switching in others (e.g., edit bays or audio
mixing rooms). To implement a stereo-mono mode, two partitions must be created
— a stereo parti-
tion and a mono partition.
This mode is the most complex to implement. It requires careful understanding of the relationship
between physical connections and the logical mapping used within the control system. It is not
guaranteed to operate satisfactorily with any router control system except the Miranda NV9000
because setup relies heavily on partitions and how status is reported when the partitions overlap.
With this option you can have a single stereo partition display on some control system interfaces
and separate mono partitions on another. Three virtual levels should be built in the router control
system: stereo, left and right.
