• 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.

from the power source during electrical storms. If possible connect mixer to
a surge protector.

FADER CLEANING AND INSTA L L
After constant use the SMX-301 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 mixer is powered off and power supply is disconnected from
back of 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 mixer by removing the connector on the
bottom of the fader.
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,
Mini Discs, 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, like 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.
Installing a fader:
1. Once original fader has been removed, simply plug the 4-pin
connector into the new fader.
2. Place fader back in mixer and replace 2 outer screws to secure 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. Pre fader 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 cross fade between channels
1 and 3.
7. Kill switches - Kill switches are used to completely eliminate Hi,
Mid, or Low frequencies from the audio. This is used for tricks
during a mix.
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 a 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 mast
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.
