9. Mono Input Jacks
These ¼" phone jacks are the line-level input connections for
channels 1 and 2. When the XLR inputs on their corresponding
channels are not in use, these linputs can be utilized.
10. USB Connector
This USB-B connection is for the USB computer interface. Use the
included USB cable to connect this to your computer's USB port.
11. Output Connectors
These balanced XLR connections will send the final stereo
line level signal sent from the main mix. These outputs can be
connected to an amplifier for sending the signal out to speakers,
or directly to active speakers.
12. Headphones Jack
This stereo output port, found on the
very front of the mixer, is suited for use
with headphones, allowing monitoring of
the mix. The audio level of this output is
controlled using the Phones/Control Room
control on the front panel.
13. DC Power Input
This standard DC power input port is for connection of the included
power supply. Please use the included power supply only as using
the incorrect voltage can cause irreversible damage to the mixer.
CONTROLS AND SETTINGS
14. 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 on the front panel. 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.

15. Power Switch
This switch is used to turn the mixer on and off. Ensure you turn
all level controls down before activating. This ensures no audio is
inadvertently sent through your system.
Channel Controls
16 PAD Button
The PAD button is used to attenuate the input signal by 25 dB.
This should only be pushed in when using line-level input devices.
17. 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
12
maintaining the quality of the feed. This can be accomplished by
adjusting it to a level that will allow the peak indicator occasionally
illuminate.
18. Compressor Control and Indicator
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.
19. TREBLE (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.
20. MID (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.
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.
