Patch AoIP Device Physical Inputs to
Transmitter Streams
Now the transmitter streams for the AoIP
devices are setup, the next step is to patch
those to the physical input ports in the
AoIP device.
Audio Inputs configuration
This page is accessed from the Devices
menu when an AoIP Device's 'Audio Inputs'
tab is selected and appears as shown
above right.
This allows the user to connect the Audio
Input ports to transmitter channels and give
the port a Label, a Gain value and switch
the 48v phantom power setting if it is a
Mic/Line Input or the SRC, if it is an AES
input as described below.
Gain Selection (Mic/Line Only)
The user clicks on the existing gain setting
and either enters a gain value or moves the
slider to the desired setting and clicks on
the 'tick box' to apply the change.
48v or SRC Selection (Mic or AES)
The user clicks on the 48v symbol or SRC
symbol next to the gain setting this will
toggle the state of that function and will
appear in Red when active.
Label Selection
The user can click on the existing label and
a label entry box appears. The user edits
the label as required and clicks on 'Apply'.
Lock Selection
The user can click on the padlock symbol

Analogue level Options
Clicking on the 3 dots icon in the top right
corner of the page, opens a drop down
shown below right which allows the user
to perform various functions. From an
analogue point of view there are two of
these of interest, the first being the ability
to set the analogue level representing
0dBFS and the second of these is to set
the 'Mic input headroom'.
On selecting the 'Analogue level at
0dBFS' option a drop down appears as
shown on the middle right of this page.
The user selects the operating level
required. The Calrec default for this is
0dBFS=18dBu.
On selecting the 'Mic Input Headroom'
option a drop down appears as shown on
the bottom right of this page.
The user selects the operating headroom
required. The Calrec default for this is
28dB.
