Important Configuration Note:
This setting is shared by the

section of the

words, both sections named

in these tabs change simultaneously
when either one is changed.

Default Settings for POTS Voice Calls
By default, a POTS voice call is sent to a codec’s encoders as per the
connection profile loaded into the codec. This is a very useful way of
integrating voice calls into a broadcast and sending the composite program
signal to the studio encoded. The program matrix in this situation is as
displayed in the following image.
Figure 25: Phone Audio Routed to Encoder by Default (TLR300B Matrix)
In this situation audio is not sent to the analog codec outputs. Incoming
audio is sent to the
Encoder/s
and can be monitored via the
Mix
(Send/Return) Pan Matrix.
As displayed in the following image, phone
audio by default is routed to the
Send
section of
the matrix – along with the other inputs.
The
BALANCE
knobs on
T
ieline
codecs control
the balance between the
SEND & RETURN
audio sent to the codec headphone outputs. The
Mix (Send/Return) Pan Matrix
provides the
flexibility of selecting which sources are allocated
to
SEND
and
RETURN
.
The audio balance between the
Decoder
audio
monitored (via
Return
) and the inputs (via
Send
)
can be controlled via the
BALANCE
knob on a
T
ieline
codec.
