8. The apparatus shall be connected to a MAINS socket outlet with a protective earthing connection.
9. Unplug this apparatus during lightning storms or when unused for long periods of time.
10. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate
normally, or has been dropped.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert
the user to the presence of “un-insulated dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a risk of electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the literature
accompanying the product.
WARNING:
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE
BEFORE YOU GET STARTED
Your mixing console was carefully packed in the factory to guarantee safe transport. Nevertheless, we

INTRODUCTION
The SMX Series of mixers are compact live sound mixing consoles. Focus is on providing the engineer with
a variety of features like additional mic inputs, multiple aux, global and local EQs, and subgroups. Input
connectivity on BT and USB are available with record output to onboard USB. In a slim, compact form-factor,
the SMX is an excellent console for small events where sound quality is paramount.

INTRODUCTION/ FEATURES/ INITIAL OPERATION

MAIN FEATURES
SMX 1008 page 3
HIGH-QUALITY OPERATIONAL AMPLIFIERS
Mono input channels are equipped with discrete microphone preamplifiers. The pre amplifier features circuit
used in high-end audio devices. This circuit uses multi-stage amplifiers to ensure high current and low
impedance, for an audio texture with crispness and richness in the low and mid frequencies.
Combined with the specially-designed operational amp, the overall result is full-bodied reproduction of low
frequencies as well as sustained high frequencies. Input channels feature combo jacks, which can accept
both XLR and TRS connectors. In addition, Trim control allows line level input to accommodate a wide variety
of instruments
BUILT-IN UNIVERSAL SWITCHING POWER SUPPLY
The SMX 1008 features a universal switching power supply. This power supply supports input voltages of
100Vto240V,forstableoperationeveninenvironmentswherepowervoltageuctuateseasily.AnACinlet
allows simple installation in environments where portability is required
16 HIGH-QUALITY DIGITAL EFFECTS
The SMX 1008 features 16 built-in effects that are based on DSP FX

SWITCHES
SMX 1008 page 6
1. MIC INPUT JACKS: These are balanced XLR-type microphone input jacks. (1: Ground; 2: Hot; 3:
Cold)
2. LINE INPUT JACKS (mono channels): These are balanced TRS phone-jack line inputs. (T: Hot; R:
Cold; S: Ground). You can connect either balanced or unbalanced phone plugs to these jacks
3. TRIM CONTROL adjusts the input signal level. To get the best balance between the S/N ratio and
the dynamic range adjust the gain, so that the PEAK indicator (9) lights only occasionally and briefly on
 thehighestinputtransients.The-60to+10scaleistheMICinputadjustmentrange.The40to+10
scale is the LINE input adjustment range.
4. EQUALISER (High, Mid and Low): This three-band equalizer adjusts the high, mid and low
frequency bands of the corresponding channel. Setting the knob to the "0" position produces a flat
response in the corresponding band. Turning the knob to the right boosts the corresponding frequency
band, while turning to the left attenuates the band
5. FX CONTROL: The aux send marked FX offers a direct route to the built-in effects processor and
is therefore post-fader and post-mute
6. PAN CONTROL: The PAN control determines the position of the channel signal within the stereo
image
7. ON/OFF SWITCH: Turn this switch on to send signal to the buses. The switch lights orange
when on
8. CLIP LED: This LED lights up when the input signal is driven too high. If this happens, back off the
TRIM control and, if necessary, check the setting of the channel EQ
9. SOLO SWITCH: The SOLO switch is used to route the channel signal to the solo bus (Solo In
Place) or to the PFL bus (Pre Fader Listen). This enables you to listen to a channel signal without
affecting the main output signal. The signal you hear is taken either before the pan control (PFL,
mono) or after the pan and channel fader (Solo, stereo)

SMX 1008 page 7
SWITCHES
10. CHANNEL FADER adjusts the level of the corresponding mono channel. Use these faders to
adjust the balance between the various channels
11. CD IN JACKS: These RCA jacks input a stereo sound source. Use these inputs when you want to
connect a CD player
12. REC OUT (L, R) JACKS: These RCA jacks can be connected to an external recorder such as an
MD recorder in order to record the same signal that is output via the STEREO OUT sockets
13. FX OUT JACKS: The FX OUT jacks carry the master aux mix (from the channel’s FX controls).
You can connect this to an external effects device to process the FX bus. The processed signal can
then be brought from the Effects device back into the STEREO AUX RETURN jacks
14. STEREO AUX RETURN JACKS: The STEREO AUX RETURN jacks generally serve as the
return for the effects mix (created using the post-fader aux sends) by connecting the output of an
external effects device. If only the left jack is connected, the AUX RETURN is automatically switched to
mono
15. MAIN OUT (L, R) JACKS : These jacks deliver the mixer's stereo output. You can use these
jacks, for example, to connect to the power amplifier driving your main speakers
16. EFFECTS DISPLAY: There are 16 different types of Effects each denoted by a number printed on
the panel. This number is shown by the display
17. PROGRAM DIAL: You can select the Effect preset by turning the PROGRAM control. The display
flashes with the number of the current preset
18. FX varies the intensity of the effects

SMX 1008 page 8
19. PARAMETER adjusts the parameter (depth, speed, etc.) for the selected effect. The last value
used with each effect type is saved
20. 7-BAND STEREO GRAPHIC EQUALIZER: This stereo graphic equalizer allows you to
tailor the sound to the room acoustics
21. STEREO AUX RETURN1 CONTROL Adjusts the level at which the signal received at the
RETURN jacks (L (MONO) and R) is sent to the STEREO L/R bus
22. CD/TAPE CONTROL adjusts the level of the CD IN jacks. Computer, Tape audio input and
sound control
23. PHONES/CTRL ROOM CONTROL: Use this control to adjust the control room output level
and the headphones volume
24. FX SEND FADER: This is the master control for the Effects level
25. MP3/BT FADER adjusts the level of MP3/BT
26. MAIN MIX FADER: This is the master level control for the MAIN OUTS
27. MP3 USB JACK: Connect a flash drive to this socket for playing MP3 audio files. This is a host
USB player
28. MP3 DISPLAY: Shows various information about audio files being played like track number, name
of the track, etc

level. The PEAK indicator lights when the output reaches the clipping level
34. BT: Press SWITCH for two seconds, the Signal LED will blink.
Using mobile phone or tablet or pc, go to the BT device list and search for MIXER-01 to pair.

36. FUSE HOLDER/IEC MAINS RECEPTACLE: The console is connected to the mains
via the cable supplied, which meets the required safety standards. Blown fuses must only be replaced
by fuses of the same type and rating. The mains connection is made via a cable with IEC mains
connector. An appropriate mains cable is supplied with the equipment.
37. POWER SWITCH: Use the POWER switch to turn on the mixing console. The POWER switch
should always be in the “Off” position when you are about to connect your unit to the mains. To
disconnect the unit from the mains, pull out the main cord plug. When installing the product, ensure
that the plug is easily accessible.
38. GND CONTACT: GND in order to avoid leakage.

You can also connect unbalanced devices to the balanced input/outputs. Use either mono plugs, or use
stereo plugs to link the ring and shaft (or pins 1&3 in the case of XLR connectors).
CAUTION! You must never use unbalanced XLR connectors (PIN 1 and 3 connected) at the MIC input
jacks if you want to use the phantom power supply.
