Auxiliary Input
The unbalanced
AUX
input on the codec is a standard RCA line level input for
interfacing with consumer electronic devices. If you are connecting the codec
AUX
output to a device that is expecting a microphone level source, i.e. a cell-
phone, this high-level output can be adjusted using the codec menus. To adjust
the level do the following:
Press
SOFTKEY 4
to access the
Menu
submenu;
Scroll using the
MENU SELECTOR (MS)
to
Configuration
and press to select
this option;
Next scroll to
Aux Output Level
and press the
MS
to select it;
The default setting is
255
in the menu. Use the
CLEAR
button to delete the
numbers and input a number lower than
255
to lower the output level; and
Press
SOFTKEY 4
which will have
OK
displayed above it to enable the
change.
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 two ways of doing it. You can use the virtual input fader
displayed in the
Control
menu for the codec, or alternatively you can use the
Gang to Knob
function in the
Rem Ctrl
menu and use one of the
INPUT
digipots
to control the
Aux
input levels.
