20. Phantom Power Switch
When this switch is in the on position, it
activates +48v of phantom power for all
microphone
inputs,
allowing
microphones (well, the ones that don't use
batteries) to be used on these channels.
Activating
Phantom
Power
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.
Channel Controls
21. Gain Control
This controls the sensitivity of the input signal of the line/
Microphone input of mono channels. 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 or slightly lower than this.
22. low Cut Filter (75 Hz)
This button, located on channels 1 through to 16, 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.
23. 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.
24. Middle Frequency Control
This control is used to provide a peaking style of boost and
cut to the level of middle frequency sounds at a range of ±15
dB. The sonic station 16 mixer also provides a sweep control,
allowing you to select a center frequency between 100 hz and
8 khz. Changing middle frequencies of an audio feed can be
rather difficult when used in a professional audio mix, as it is
usually more desirable to cut middle frequency sounds rather
than boost them, soothing overly harsh vocal and instrument
sounds in the audio.
25. low Frequency Control
This control is used to give a shelving boost or cut of ±15 dB
to low frequency (80 hz) sounds. This will adjust the amount
of bass included in the audio of the channel, and bring more
warmth and punch to drums and bass guitars.

26. AUX Controls
These four AUx controls alters the signal level that is being
sent to the auxiliary 1 to 4 mixing buses, the signal of which is
suitable for connecting stage monitors, allowing artists to listen
to the music that is being played, or to fed to an external effect
processors. AUx 1 and AUx 2 each feature a Pre/Post button,
which alternates the feed to the AUx mixing bus between a
post and pre-fader feed. AUx 3, on the other hand, acts as
an eFx send for the internal effect processor, or simply as an
Auxiliary output. Both the AUx 3(eFx) and AUx 4 controls are
post fader and are sent directly to the corresponding outputs.
27. 5/6 Shift Button
This button changes the routing of the AUx 3 and 4 controls,
allowing the channel's signal to be directly output through the
AUx 5 and 6 outputs respectively.
28. Pan Controls
This alternates the degree or level of audio that the left and
right side of the main mix should receive.
29. On Button and Indicator
This turns the channel on, allowing the user to use the feed
from the channel's inputs to supply the MAin l/R, gRoUP 1/2,
GROUP 3/4, AUX and EFX buses (as specified by the user, of
course). The corresponding indicator will be illuminated when
turned on.
30. Sig Indicator
This leD indicator shows when the input level reaches -
20 dBu, basically showing when a signal is received by the
corresponding channel.
31. 1-2, 3-4 and l-r Buttons
These handy buttons allow you to decide the audio path of
the corresponding channel. Pushing the "1/2" or "3/4" buttons
allows the signal to be sent to the group 1/2 or 3/4 mixes
respectively, where the "l-R" allow it to be sent to the Main
l/R mixes.
