PLEASE READ CAREFULLY BEFORE USE

FAILURE TO FOLLOW THE INSTRUCTIONS PRINTED BELOW MAY VOID THE WARRANTY

  • Follow all security advice printed on your mixer
  • When removing the unit’s AC plug from the power source, grasp and pull the plug, NEVER the cord itself!
  • Avoid placing your mixer near heat sources, such as power amplifiers.
  • When in use, place your mixer on a stable surface, away from vibration. Always use care when carrying your mixer. Impact, or heavy vibration may compromise the unit’s mechanical integrity. The manufacturer is not responsible for damage resulting from an impact, or misuse.
  • When in use, place your mixer away from sources of hum or noise, such as transformers, or electric motors.
  • To prevent overheating, always provide your mixer with adequate ventilation and air space.
  • Avoid stepping on your mixer’s AC cord. Repeated compression of the cord may lead to electrical shorting.
  • To avoid damage due to AC voltage peaks, always disconnect your mixer from the power source during electrical storms. If possible connect the mixer to a surge protector.
  • Your mixer contains no user-serviceable parts. The manufacturer is not responsible for any damage or personal injury resulting from unauthorized user-servicing or modifications. In addition, the warranty will be void if any unauthorized service by the user is detected. Always return your mixer to an authorized Stanton dealer for servicing.

FADER CLEANING AND INSTALL

After constant use, the faders may need to be cleaned and lubricated from time to time. This will ensure long life and keep a smooth feeling throughout the fader’s lifetime. Follow the instructions below to lubricate and clean your faders:

Removing a fader:

  1. Make sure the mixer is powered off and the power supply is disconnected from the back of the mixer.
  2. Remove the fader to be cleaned or replaced by unscrewing the 2 outer screws on the fader plate (removing the 2 inner screws will detach the fader from the fader plate).
  3. Disconnect the fader from the mixer by removing the connector on the bottom of the fader.

Installing a fader:

  1. Once the original fader has been removed, simply plug the 4-pin connector into the new fader.
  2. Place the fader back in the mixer and replace 2 outer screws to secure the fader.

DESCRIPTION OF FUNCTIONS

  1. Microphone 1 input – This combo (1/4”/XLR) connector is used to connect a microphone. The volume is controlled by the MIC 1 knob.
  2. Mic 1 level – Controls the input level of Microphone input 1.
  3. Mic equalizer – Individual controls for high frequency, midrange, and low-frequency equalization. The EQ controls both Microphone inputs. Note: Any changes made to EQ settings will change the overall output level.
  4. Prefader listen – Selects the channel(s) – 1, 2, or 3 – to be previewed in the headphones.
  5. Channel faders – Controls the output volume of each channel. The signal is routed to the line faders after the gain, EQ, pan, and effects.
  6. Crossfader – The crossfader is used to crossfade between channels 1 and 3.
  7. Kill switches – Kill switches are used to completely eliminate Hi, Mid, or Low frequencies from the audio. This can be used as a performance effect.
  8. Headphone outputs – This is the headphone output jack to connect your headphones.
  9. Cue pan – Fades the headphone output between the PFL signal (selected by the Cue Select buttons) and master output, effectively allowing the user to preview a mix.
  10. Cue level – Controls the volume of the headphone output.
  11. Booth level – Controls the booth output level. This is basically the 2nd output. It is usually used for monitoring in a DJ booth but can be used for various applications.
  12. Master output Pan- This is the pan or balance control for the master output.
  13. Master output level – Controls the overall output level of the mixer.
  14. Output meters – These LEDs let you know if the audio coming out of the mixer is loud enough (or too loud!). If the LEDs reach the red, the mixer is probably clipping or distorting.
  15. Input selectors – These toggle switches select the input source between phono and line for each channel.
  16. Input gains – Controls the input sensitivity level of each channel. An LED meter is provided on each of the 3 channels for proper adjustment of the levels.
  17. Channel equalizer – Individual controls for high frequency, midrange, and low-frequency equalization with +9dB/Kill adjustments. Note: Any changes made to EQ settings will change the overall output level.

Power: This is the power switch to turn the mixer “ON” or “OFF”
AC IN: This is the Input connection for the included power supply.
Line: Line inputs (represented by the letter L, followed by the input number) are used to connect to line-level sources such as CD players, MiniDiscs, DATs, samplers, etc.
TT: TT (or phono) inputs are used to connect to turntables.
Ground: Connects to the turntable ground cable to eliminate electrical hum. Ground cables are usually supplied with turntables
Master: Connects to an amplifier, EQ, crossover, or other outboard signal processing.
Booth: This is a second output, as the master output. It is usually used as a separate output in the DJ Booth for the DJ to monitor the mix
REC: This is the record output. The output level is static in this case, there are no volume controls. It is used to connect directly to tape or CD recorders. The volume can be set from the recording device.
