42. 2T Return Controls
Turning the 2T Return level control adjusts the signal
level of the feed from the 2T Return inputs, the signal
of which is sent to the Main L/R mixing bus. Pushing
the "to Ctrl Rm" button sends the signal to the Control
Room/Phones mixing bus also. These also double
as the input controls for the USB interface on the
AM642D USB.

43. +48V Indicator
This indicator will illuminate when Phantom Power
is activated.
44. Power Indicator
The Power Indicator will light up when the power of
the mixer is on; in case you weren't too sure.
45. Level Meter
This dual 12-segment level meter gives an accurate
indication of when audio levels of the Main L/R output
reach certain levels. The 0 dB indicator illuminates
is approximately equal to an output level of +4 dBu
(balanced), and the PEAK indicator illuminates
slightly before the signal is dynamically clipped. It is
suggested that users set the various levels controls
so that the level meter sits steadily around the 0
dB mark to make full use of the audio while still
maintaining fantastic clarity.
When the Solo indicator (located beside the Level
Meter) is illuminated, one or more Solo buttons
has been pushed and the Level meter will display
properties of the Solo signal, which can be helpful
with setting of channel properties. If Solo indicator
illuminates green, this means the Solo feed is a pre-
fader signal. If the solo indicator illuminates red, the
feed is post-fader. If the no Solo buttons are activated,
the 2T Return signal properties are displayed by the
Level Meter, unless the "To Ctrl Rm" button is not
pressed, in which case the Main L-R signal properties
will be displayed.

46. Group Controls
These two faders are the final level control for the
Group 1 and 2 audio feeds, sent to the Group 1 and
2 outputs. These faders can be fed a signal from the
various mono and stereo channels, as well as EFX
Returns, depending on your selections. When pushed
all the way up, these faders provide 10 dB of gain to
the signal, and, when set all the way down, effectively
mute the signal. The Group Controls also feature Left
and Right buttons, which allow you to send the Group
1-2 signals to the Main Left and Right mixing buses.
47. Main L/R Faders
These two faders are the final level control for the
Main Left and Right audio feeds, sent to the Main L
and R outputs. These faders are possibly fed by the
various mono and stereo channels, as well as AUX
and EFX returns and 2T inputs, depending on the
your selections. When pushed all the way up, these
faders provide 10 dB of gain to the signal, and, when
set all the way down, effectively mute the signal.
