20.3. Routing Matrices Explained
At the heart of
T
ieline
codecs is a digital routing switcher. It enables the codec to
be configured for a whole range of possible broadcast applications, particularly
where different configurations for inputs, outputs and monitoring are required. It
also enables the user to configure for POTS, ISDN, GSM, 3G, X.21, satellite
ISDN, IP/Internet, single channel or dual channel operation. There may also be
a requirement for communications as well. The router can even configure full
talkback operation between a studio producer and the remote broadcast codec.
Each

codec profile contains 16 programmable routing matrices (as
displayed in the
Matrix Map
menu), that enable the user to program audio
routing for normal program, cue functions, remote cue, phone cue, local talkback
and remote talkback. Two separate ‘Global’ matrices for muting program and
monitoring are also provided but are not included in the profile.
All routing matrices have eight inputs, six of which are hard-wired and two are
virtual. Of the six wired inputs, five are balanced mic/line inputs, one is shared
between a phone coupler and an auxiliary input. The two virtual inputs are for
the two decoder channels.
There are 12 outputs in the router of which 8 are wired and 4 are virtual outputs.
Of the 8 wired outputs, 2 are balanced outputs, 4 are for headphone monitoring,
one is for a phone connection (via a POTS module) and one is for the
Aux
(auxiliary) output. Of the 4 virtual outputs, 2 are for the
Encoders
and 2 are for
the
PPM
meters.

A set of reference matrices is provided with all
T
ieline
codecs to provide a starting
point for setting up the codec. Other matrices can be created and amended by
the
Matrix Editor if you have purchased this option from T
ieline
. To check if you
have matrix functionality enabled in your codec go to [Menu] > [Unit Details] and
scroll to [Features Enabled]. If
Matrix
is not listed then you will need to enable this
within your codec. This process is explained in the following section.
