Master Section
27. Phantom Power Switch
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 above the left channel Level Me-
ter. 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 con-
sulted.

bus (as taken from the AUX controls on each chan-
nel strip), the audio of which is sent to the AUX Send
output (and sent to the Control Room/Phones output
when the AUX to Ctrl button is engaged).
29. 2T Return Routing Buttons
These two buttons allow users to decide the desti-
nation of the signal received by the RCA 2T Return
inputs. The “to Main” button sends the signal to the
main mix, whereas the “to Ctrl Rm” sends the signal
to the Control Room mixing bus for monitoring.
30. AUX “to Ctrl” Button (AM440 only)
When this button is activated, the AUX send signal
(the level of which is decided by the AUX send con-
trol) will be sent to the Control Room mixing bus for
monitoring purposes.
31. Ctrl Rm / Phones Control
This control is used to adjust the audio level of the
Control Room feed, which is sent to both the Control

left and right audio feed, sent to the Main L and R
outputs.
33. Level Meter
The AM’s stereo 4-segment level meter gives an ac-
curate 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.
34. +48 Indicator
The +48 Indicator illuminates whenever the Phan-
tom Power is activated.
35. Power Indicator
The Power Indicator will light up when the power of
the mixer is on.
