27. Phantom Power Switch
When this switch is in the on position it activates +48V of
phantom power for microphone inputs, allowing condenser
microphones to be used on these channels. On the
AM240D, the phantom power switch is located on the rear
of the mixer – beside the power switch.
NB. Phantom Power should be used in conjunction with condenser
microphones only. Do not engage Phantom Power if a condenser
microphone is not being used to avoid causing damage to the
mixer's circuitry.
28. Control Room / Phones Control
This control is used to adjust the audio level of the phones
feed, to be sent to the Phones output. This can then be
used in conjunction with headphones or, if required, as an
auxiliary output. This control also adjusts the level sent to
the Control Room output for use in monitoring, as a side
fill, or for the addition of other external devices.
29. Main L-R Control
This control is final level control for the main left and right
audio feed, sent to the Main L and R output.
30. Level Meter
The AM series' level meters give 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 so that the uppermost LED
flashes only occasionally (and perhaps a pinch below that).
The AM240 and AM240D both feature dual 4-segment
level meters.
31. Power Indicator
The power indicator will light up when the power of the
mixer is on.
