1. POWER IN – Use the included power adapter to connect the mixer to a power outlet. While the power
is switched off, plug the power supply into the mixer first, then plug the power supply into a power
outlet.
2. VOLTAGE SELECTOR – This 2-position switch sets the AC input voltage for the speaker. U.S. users
should set this switch to "100-120V" whereas U.K. and most European users will need to set this to
"220-240V".
3. POWER SWITCH – Turns the mixer on and off. Turn on the mixer after all input devices have been
connected and before you turn on amplifiers. Turn off amplifiers before you turn off the mixer.
4. GROUNDING TERMINAL – If using phono-level turntables with a grounding wire, connect the
grounding wire to these terminals. If you experience a low "hum" or "buzz", this could mean that your
turntables are not grounded.
Note: Some turntables have a grounding wire built into the RCA connection and, therefore, nothing
needs to be connected to the grounding terminal.
5. PHONO INPUTS (RCA) – Connect phono-level devices, such as turntables, to these inputs.
6. LINE INPUTS (RCA) – Connect line-level devices, such as CD players, samplers or audio interfaces,
to these inputs.
7. CH3 USB – Outputs the Record mix to your computer for recording purposes or sends incoming audio
from your computer to mixer's Channel 3.
8. MIC 2 INPUT – If you would like to use an additional 1/4" microphone on Channel 4, connect it to this
input. To route the microphone signal to the mix, you will need to flip the Channel 4 Input Selector
switch, located on the top panel, to "Mic".
9. MASTER OUTPUT (BALANCED XLR) – Connect this low-impedance XLR output to a speaker or
amplifier system. The level of this output is controlled with the MASTER FADER on the top panel.
10. MASTER OUTPUT (RCA) – Use standard RCA cables to connect this output to a speaker or amplifier
system. The level of this output is controlled by the MASTER FADER on the top panel.
11. BOOTH OUTPUT (RCA) – Use standard RCA cables to connect this output to a booth monitoring
system. The level of this output is controlled by the Booth knob on the top panel.
12. RECORD OUTPUT (RCA) – Use standard RCA cables to connect this output to a recording device,
such as a CD recorder or tape deck. The level of this output is based upon pre-master levels.
