10. Main L and R Outputs
These two ports will output the final stereo balanced 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).
11. 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, among other possible uses.
12. ALT 3-4 Output
These unbalanced outputs are fed from the ALT 3-4 mix and
can be used in conjunction with a large array of input devices,
including signal processors, recording devices, monitor mixers,
and so on. The ALT 3-4 mix is created by muting signals on
channels 1 through 8. If no channels are muted, these outputs
will send the main mix.
13. USB Connector (AM1204FX USB Only)
This USB connector can be used to connect the AM1204FX 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.

CONTROLS AND SETTINGS

Back Panel

14. Power Switch and AC Connector
The power switch, located on the rear of the mixer, is used to
activate the mixer. But there's no point in activating the mixer
if there's no power, therefore an AC power connector has been
included to ensure your mixer gets the power it needs. Please
use the power cable that is included with this mixer only.
15. 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
coming 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.

Channel Controls

16. Low Cut Filter (75 Hz)
This button, located on channels 1 through to 4, will activate a
low-cut / 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.
17. Gain Control
These controls, found on each input channel, allow users to
adjust the sensitivity of the input signal for 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. All 4 mono
channels feature this control.

18. Compressor Control and Indicator (AM1204FX USB Only)
This controls the onboard compressor function on mono channels.
Turning this control up towards the 12 o'clock position will adjust
the threshold and ratio of the compressor at varying degrees.
Once you reach the 12 o'clock position, the control will then
adjust the compression settings along with an onboard expander
(or, in other words, a "compander"). The LED that accompanies
this control will light up when the compressor is triggered. This
control and indicator can only be found on mono channels of the
AM1204FX USB.
19. High Frequency Control
This control is used to give a shelving boost or cut of ±15 dB to
high frequency (12 kHz) sounds. This will adjust the amount of
treble included in the audio of the channel, adding strength and
crispness to sounds such as guitars, cymbals, and synthesizers.
