10. Line Inputs
These inputs accept typical 1/4" TRS balanced or TS unbalanced
inputs, for balanced or unbalanced signals. There are various
numbers of these inputs depending which mixer you are using.
They can be used in conjunction with a wide range of line level
devices, such as keyboards, drum machines, electric guitars, and
a variety of other instruments.
11. Channel Inserts
Located on the rear of the
AM442D USB and AM642D USB,
the primary use for these TRS
phone jacks is for the addition of
external devices, such as dynamic
processors or equalizers, to the
mono input channels on both of
these units. This includes channels
1 to 4 on the AM442D USB and
channels 1 to 6 of the AM642D USB. This will require a Y cord
that can send (pre-fader and pre-EQ) and receive signals to and
from an external processor.

12. Control Room Outputs
These two 1/4" phone jack outputs feed the signal altered by the
Control Room / Phones level control on the face of the mixer. This
output has extensive use, as it can be used to feed the signal
from the mixer to an active monitor, for the monitoring of the
audio signal from within a booth, or, alternatively, for the addition
of external signal processing devices or mixers, as well as acting
as a "side fill" output, supplying audio to indoor areas that the
main speakers do not reach.
13. Group Out
These 1/4" phone jacks output the final feed from the Group 1
and 2 faders on the main mixer. These outputs can be used to
feed a wide range of devices, such as mixers, signal processors,
and even to connect an amplifier and speakers to be used along
with the Main Speakers, for a more rounded audio experience.

14. Main Out
These two XLR ports will output
the final stereo line level signal
sent from the main mixing bus. The
primary purpose of these jacks is
to send the main output to external
devices, which may include power
amplifiers (and in-turn, a pair of
speakers), other mixers, as well
as a wide range of other possible
signal processors (equalizers,
crossovers, etcetera).
15. USB Port
This USB connector can be used
to connect the AM442D USB and
AM642D USB to any modern Windows
or Mac-based computer. Doing so will
allow users to get a stereo signal both
to and from the computer.
16. 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
Meter. 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.
17. Power Switch
This switch is used to turn the mixer on and off.
18. Power Connector
This port is for the addition of a power cable, allowing power to be
supplied to the mixer. Please use the power cable that is included
with this mixer only.

19. Line/Mic Gain Control
This controls the sensitivity of the input signal of the Line/
Microphone input. The gain should be adjusted to a level that
allows the maximum use of the audio, while still maintaining the
quality of the feed. This can be accomplished by adjusting it to a
level that will allow the peak indicator occasionally illuminate.
20. Low Cult Filter (75 Hz)
This button will activate a high-pass filter that reduces all
frequencies below 75 Hz at 18 dB per Octave, helping to remove
any unwanted ground noise or stage rumble.
