Master Section
29. 2T / USB to Main
This button will allow you to send the signal from your 2T Return
inputs or the USB interface return signal to the control room
output and headphones.
30. 2T / USB to Control Room
Pushing this button will send the signal from the 2T Return
inputs and/or the USB interface to the control room output and
headphones mix.
31. Phones Control
This control is used to adjust the audio level to Phones outputs
(to be used in conjunction with headphones for monitoring).
32. Phantom Power Switch and Indicator
When this switch is in the on position, it activates +48V of
phantom power for all microphone inputs, allowing condenser
microphones (well, the ones that don't use batteries) to be used on
these channels. Activating Phantom Power will be accompanied
by an illuminated LED. Before turning Phantom Power on, turn
all level controls to a minimum to avoid the possibility of a ghastly
popping sound from the speakers.
NB. Phantom Power should be used in conjunction with balanced
microphones. When Phantom Power is engaged, single ended
(unbalanced) microphones and instruments should not be used on the
Mic inputs. Phantom Power will not cause damage to most dynamic
microphones, however if unsure, the microphone's user manual should
be consulted.
33. Power Indicator
The Power Indicator will light up when the power of the mixer is
on.
34. Level Meter
The AM440D USB-K's stereo 4-segment level meter gives an
accurate indication of when audio levels of the MAIN L/R output
reach certain levels. It is suggested for the maximum use of
audio to set the various levels controls to a level slightly below
that which would cause the Peak LED to light up. This will help
you get the most out of your audio without causing any distortion.
35. Main L-R Control
This 60mm fader is final level control for the main left and right
audio feed, sent to the Main L and R outputs.
