1. LINE | PHONO INPUTS (RCA) – Connect your audio sources to these inputs. These inputs can accept both line and phono-level signals.
2. GROUNDING TERMINAL – If using phono-level turntables with a grounding wire, be sure to 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 the grounding wire built into the RCA connection and, therefore, nothing needs to be connected to the grounding terminal.
3. LINE | PHONO SWITCH – Flip this switch to the appropriate position, depending on the device connected to the PHONO INPUTS. If using phono-level turntables, set this switch to "PHONO" to provide the additional amplification needed for phono-level signals. If using a line-level device, such as a CD player or sampler, set this switch to "LINE."
4. LINE INPUTS (RCA) – Connect line-level devices, such as CD players, samplers or audio interfaces, to these inputs.
5. MIC 2 INPUT – If you would like to use an additional 14 " microphone, connect it to this input. Adjust the levels for this input with the MIC GAIN CONTROLS.
6. CUE / SEND OUTPUT – Connect external monitors to this output to monitor pre-fader audio sent to the Cue Channel (see #20 under TOP PANEL FEATURES).
7. RECORD OUTPUT (RCA) – Use standard RCA cables to connect this Record output to a recording device, such as a CD recorder or tape deck. The level of this output is based upon pre-master levels.
8. BOOTH OUTPUT (RCA) – Connect an external monitoring device, such as powered monitors, a PA system, or a home stereo, to this output. The controls this output are located on the front panel.
9. MASTER OUTPUT (RCA) – Use standard RCA cables to connect this Master output to a speaker or amplifier system. The level of this output is controlled by the Master knob on the top panel.
10. MASTER OUTPUT (BALANCED) – Connect this low-impedance XLR output to a PA system or powered monitors. The level of this output is controlled by the Master knob on the top panel.
11. FADER START – If you would like to use the mixer's "fader start" to automatically start and cue music from external devices via the CROSSFADER, connect these outputs to your fader start-compatible device. You can use standard 1/8" stereo cables to make these connections.
12. EQUALIZER DEFEAT - Switch this to turn off the GRAPHIC EQUALIZER (see #12 under TOP PANEL FEATURES).
13. POWER IN – Use the included power cable 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.
14. 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."

INPUT CONTROLS

1. CHANNEL FADER – Adjusts the audio level of the corresponding channel.
2. INPUT SELECTOR – Selects the input source to be routed to the corresponding channel. Input jacks are located on the rear panel.
3. CHANNEL GAIN – Adjusts the channel's pre-fader and pre-EQ gain level.

MICROPHONE CONTROLS

1. MIC TREBLE & BASS – Adjusts the treble (high) and bass (low) frequencies of the audio for both mic inputs.
   Tip: If you experience feedback when using a microphone at loud levels, try turning down the high (treble) frequencies.
2. TALKOVER SWITCH – Toggles between three “talkover” settings, allowing you to speak over the music. (Talkover only applies to MIC 1. MIC 2’s level can only be controlled by its MIC GAIN knob.)
3. -12dB – Reduces the combined levels of Channels 1-4 to -12dB (an appropriate “talkover” level).
4. ON – Leaves Channels 1-4 at the levels you designated while the mic remains on.
5. AUTO – Automatically reduces the combined levels of Channels 1-4 to -12dB whenever you talk into the DJ MIC.
6. TALKOVER SENSITIVITY – Adjusts the volume threshold at which auto-talkover activates. The higher the sensitivity, the quieter you need to speak into the mic to activate auto-talkover.
7. MIC GAIN - Adjusts the audio level of the microphone signal. The MIC 1 knob controls the volume of DJ mic input. The MIC 2 knob controls the volume of the MIC 2 input.
8. MIC 1 INPUT - Connect a microphone to this input with an XLR or 14 cable.

CROSSFADER CONTROLS

1. CROSSFADER ASSIGN - Selects which input channel will be heard when the crossfader is moved towards this knob. All channels not assigned will remain active.

2. CROSSFADER - Blends audio between the channels assigned to the left and right side of the crossfader.

Note: The crossfader is user-replaceable if it should ever wear out. Simply remove the facepanel, then remove the screws holding it in position. Replace the fader with a quality authorized replacement from your local Numark retailer only.

1. FADER START – Enables or disables "fader start" on the corresponding side of the crossfader. When fader start is enabled on one side, moving the crossfader toward that side will cause any fader start-compatible device (connected to the FADER START output on the rear panel) to start playing.

EQUALIZER

1. GRAPHIC EQUALIZER (EQ) – Adjusts the high, mid-range, and low frequencies of the combined audio output from Channels 1-4. EQ compensates for differences in source material sound quality. The center frequencies of this 5-band graphic equalizer are 63Hz, 250Hz, 1kHz, 4kHz and 16kHz. Faders have a center detent for an accurate "flat" response.

Tips:

• Boosting (increasing) the 63Hz band will increase the deep bass tones and "kick drum" sounds, but could cause your amplifiers to "clip" or distort if set too high.
• Slightly cutting (decreasing) the 250Hz and 1kHz bands will give the sound some extra clarity.
• Boosting the 16kHz band will give the audio a sharper tone.

• As a general rule, the less equalization, the better.

• EQ ADJUST – Determines how much the equalization changes when you move the EQ faders. When this button is raised, the EQ faders will adjust each band by 12dB. When the button is pressed, the EQ faders will adjust each band by 6dB.

OUTPUT CONTROLS

1. MASTER FADER – Adjusts the output volume of the Program mix.
2. STEREO / MONO – Adjusts the Program mix for stereo or mono operation.
3. BALANCE – Adjusts the balance of right to left audio of the Program mix.
4. BOOTH FADER- Adjusts the audio level from the Booth output level. (This can also be used to supply line level audio to a lighting controller or to lights that are sound activated.)
5. METER MODE - Determines whether audio from the Program mix or Cue channel is sent to the STEREO LEVEL INDICATOR.
6. STEREO LEVEL INDICATOR – Monitors the audio level of the Program mix or Cue channel, depending on the position of the METER MODE button.

CUE CONTROLS

1. CUE / SEND – Sends the pre-fader audio Cue channel for monitoring.
2. CUE MODE – When pressed, this button sends all audio in the Cue channel to the left side of the headphones and the Program mix to the right side of the headphones. When raised, you may control the balance of the Cue channel and Program mix with the Cue Blend fader.

HEADPHONE CONTROLS

1. MIX – Slide this to mix the Cue channel and Program mix in the headphones. When all the way to the left, only channels routed to the Cue channel will be heard. When all the way to the right, only the Program mix will be heard. The CUE MODE button must be set to BLEND for this fader to work (see #21).
2. HEADPHONE GAIN – Adjusts the volume level of the headphone output.
3. HEADPHONE OUTPUT – Connect your 1/4" headphones to this output for cueing and mix monitoring.

POWER

1. 12V LIGHT CONNECTION – You can connect a 12-volt gooseneck lamp here.
2. 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.
