20 Segment Bright LEDs

Grounding terminal

Ok, now that we’ve covered the SMX.311 basics, let’s get started!

Quick Setup Diagram

Review this setup diagram. (Figure 2.1) Make sure all faders are at "zero" and all devices are OFF. First, connect all input sources

and processors. Next, connect your microphone and monitor headphones. Finally, connect the stereo outputs to the power

ampliﬁer(s) and/or audio receivers such as tape decks. Plug your mixer into AC power. Now you are ready to switch everything ON.

important: Always switch ON your audio input sources such as turntables or CD players ﬁrst, then your mixer, and ﬁnally any

ampliﬁers. When turning OFF, always reverse this operaton by turning oﬀ ampliﬁers, then your mixer, and then input devices.

1. Mic on/off/TalK Switch: Turns the Mic ON or OFF. When the switch is in the TALK positon, the mixer’s sound level will

decrease around 14 dB (except the Mic channel) so that the microphone is more clearly heard over the music.

2. Mic level: Adjusts the microphone input level.

3. Cue level: Adjusts the headphone volume output level.

4. Cue Mix: Allows you to preview channel audio to your headphones. Listen here before bringing up channel faders or moving

the crossfader.

5. Channel eQ: Adjusts the HI, MID, and LOW frequency levels of the Phono or Line input. Range: -26 dB to 9 dB.

6. Channel fader: Controls the output level of the selected input (Phono or Line).

7. Crossfader: Controls the audio signal that is sent to the outputs. When the Crossfader is set to CH-1 (hard leﬅ), only channel

1 (Phono or /Line) will be sent to the outputs and when is set to CH-3 (hard right), only channel 3 (Phono or /Line) will be sent

to the outputs. If the Crossfader is centered, both channels will be sent to the outputs. Channel 2 is not aﬀected by the

crossfader.

8. Mic input: Connect a standard unbalanced (1/4") microphone.

9. Headphone output: Insert your ¼” headphones plug here.

10. Pfl (Pre fade listen) butons: These butons allows you to set each channel in “CUE” mode. If you press CUE 1 for example,

(the red LED located to its will glow) the CH-1 signal will be sent to the headphones. Set the CUE MIX knob (4) to the CUE

positon (leﬅ). To prevent any potental ear damage, progressively adjust the cue level using the CUE LEVEL knob (3).

11. booth: This knob allows you to adjust the level of the signal to be sent to the DJ Booth monitor system. Please read (19).

12. Pan: Used to adjust the leﬅ-right balance of the master output.

13. Master level: Controls the overall output level.

14. gain: Adjusts the volume of the Phono or Line input.

15. level indicators: The dual LED’s indicators display the master output level.

16. Source input Selector Switch: Selects the input source assigned to each channel. Each channel can be assigned to only one

input source at a tme.

17. Power Switch: Turns the mixer ON or OFF.

18. Power Connector: While the power is switched OFF, plug the power supply into the mixer ﬁrst, and then plug it into the outlet.

19. booth output: Using a RCA cable, connect from the SMX.311 booth output to the DJ booth monitor system inputs.

20. balanced Master output: TRS balanced (1/4”) connectors are typically used to connect to a P.A. mixer or an ampliﬁer for live

performances, or a recording console.

21. Unbalanced Master output: RCA connectors are typically used to connect to a home stereo, or to another mixer with RCA

inputs for practcing or team routnes.

22. line inputs: Unbalanced RCA jacks for connectng stereo audio from line level sources such as CD players, Hi-Fi VCRs, cassete

decks, DAT machines, laser discs, tuners, Mini Discs, even synthesizers or other mixing consoles. Plug mono audio sources into

both Leﬅ and Right inputs using a "Y" cable connector.

23. Phono inputs: Plug your turntables in here. When these connectors are used, your signal is fed directly to the high-quality

RIAA phono pre-ampliﬁers. Only connect turntables here. Line level sources will overload the sensitve phono pre-amps and

will cause distorton.

24. gnD: To eliminate electrical hum, connect the ground cable from your standard turntable ground post to the SMX.311 ground

terminal. Some turntables (like the Stanton STR8.150) do not require a grounding wire.

Troubleshootng

Problem / Symptom

Possible Cause / Soluton

no Sound.

Is the power ON? Based on your connectons, check that you

have properly set the Channel Input (Phone-Line). Make sure

that the Input Gain, Channel Fader, and Master output are

turned up. Make sure the channels are properly assigned to the

Crossfader.

no Sound-Headphones.

Check the Cue Level, Cue Mix, and Cue buton setngs.

Mixer sounds noisy.

If a microphone is not being used, move the Mic switch to the

OFF positon and turn all its related controls down.

Microphone doesn’t work.

Is the Mic Level turned up? Does the microphone require

phantom power? This mixer does not provide microphone

phantom power.

Sound is distorted-line input.

Turn down the Input Gain Control. Check EQ setngs.

Sound is distorted-Phono input.

Only plug turntables into this input, do not plug in CD players or

other Line Level sources. Turn down the Input Gain Control and

check EQ setngs.

i hear hum.

Make sure you are using good shielded audio cables. Some less

expensive audio cables can be susceptble to hum and

interference. Keep your audio cables away from AC power cables

and AC transformers. Make sure the mixer is not mounted too

close to high power ampliﬁers or lightng equipment power

supplies or ballasts. Make sure your turntables are properly

grounded to the back of the mixer if they include a grounding

wire.

i hear feedback.

If you are using a microphone, make sure that you are not too

close to the speakers or headphones. If you hear feedback on

the Phono Input, then the turntable may be mounted to close

to the speakers and/or subwoofer. Also, make sure the turntable

base is placed on a surface that does not vibrate or resonate

easily when the speakers are turned up loudly.
