Important Note on Aux Input Gain:
If you are using the
Aux
input on the codec and you want to adjust the gain of
the input there are another two ways of doing it. You can use the Aux input fader
displayed in the
Control
menu or use the
Gang to Knob
function in the
Rem Ctrl
menu with one of the
INPUT
digipots to control input levels.

1.
A POTS phone line, an ISDN line, an Ethernet connection, a GSM
module, a 3G USB module, an X.21 module or satellite ISDN
connection is connected to both the local and remote codecs.
2.
An audio source (e.g. microphone, CD player oscillator etc) is
connected and that audio levels have been set using either the
