MAIN FEATURES
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

SWITCHES
SMX SERIES page 5
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. 48V INDICATOR: Thered“48VLEDlightsupwhenphantompowerisswitchedon.Phantom
power is required to operate condenser microphones
4. PHANTOM +48 V SWITCH: This switch toggles phantom power on and off. When the switch
 isonthemixersupplies+48VphantompowertoallchannelsthathaveXLRmicinputjacks
5. 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
6. LOW CUT SWITCH: This switch toggles the HPF on or off. The HPF cuts frequencies below
75Hz
7. SIGNAL LED: This is a signal presence indicator which glows when signal is applied to input
8. 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. The center frequency of the mid equalizer can be
changed with the help of a frequency control which can be varied continuously from 100Hz to 8kHz
9. AUX CONTROL: Monitor and effects busses (AUX sends) source their signals via a control from
one or more channels and sum these signals to a so-called bus. This bus signal is sent to an aux send
connector (for monitoring applications: MON OUT) and then routed, for example, to an active monitor
speaker or external effects device. In the latter case, the effects return can then be brought back into
the console via the aux return connectors. All monitor and effects busses are mono and tapped into
 postEQofferingamplicationofupto+15dB
10. 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
11. PAN CONTROL: The PAN control determines the position of the channel signal within the stereo
image. When working with subgroups, you can use the PAN control to assign the signal to just one
output, which gives you additional flexibility in recording situations. For example, when routing to
subgroups 3 and 4, panning hard left will route the signal to group output 3 only, and panning hard
right will route to group output 4 only

SWITCHES
SMX SERIES page 6
12. MUTE LED: The MUTE LED indicates a muted channel.
MUTE Switch: Pressing this switch mutes the corresponding channel.
CLIP LED: The PEAK 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.
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)
13. SUB SWITCHassignstheoutputofthecorrespondingchanneltotheSUBbus
14. MAIN SWITCH assigns the output of the corresponding channel to the MAIN bus
15. CHANNEL FADER adjusts the level of the corresponding mono channel. Use these faders to
adjust the balance between the various channels
16. CHANNEL FADER: The function of this is same as the channel fader of mono channels
17. STEREO AUX RETURNS 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
18. CONTROL ROOM OUT JACKS: The control room output is normally connected to the
monitoring system in the control room and carries the stereo mix or, when selected, the solo signals
19. FX OUT JACKS: The FX OUT jack should be used when hooking up a monitor power amp or
active monitor speaker system. The relevant FX path should be set pre-fader
20. FX FOOT SW JACK: Connect a standard foot switch to the foot switch jack and use this to
switch the effects processor on and off. A light at the bottom of the display indicates whether the
effects processor has been muted by the foot switch
21. AUX SEND JACK: The AUX SEND jack carries the master aux mix(from the channel's AUX
controls)
22. SUB OUT (1 - 2) JACKS:Theseimpedance-balanced*TRSphonejacksoutputtheSUB1/2

other such device.

SMX SERIES page 7
23. 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.
24. USB DC5V CONNECTOR: ThisisaUSB-Atypeconnectortopowera5VDClamp
25. EFFECTS DISPLAY: There are 99 different types of Effect each denoted by a number printed on
the panel. This number is shown by the display
26. PROGRAM DIAL (JOG): You can select the Effect preset by turning the PROGRAM control. The
display flashes with the number of the current preset. To recall the selected preset, press the button;
the flashing stops. You can also recall the selected preset with the foot switch
27. FX CONTROL THE AUX SEND (FX) JACK carries 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
28. REPEAT CONTROL adjusts the parameter (depth, speed, etc.) for the selected effect. The last
value used with each effect type is saved
29. FX TO AUX CONTROL: This controls the level of Effect to AUX1 AUX2 AUX3 AUX4
30. 9-BAND STEREO GRAPHIC EQUALIZER: This stereo graphic equalizer allows you to
tailor the sound to the room acoustics (defeatable)
31. AUX SEND CONTROL Use this fader to control the signal level at AUX output jack
32. 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.
33. TAP SWITCH: Press this switch to change the repeat time. For short repeat time, press rapidly, for
longer repeat time, press slowly
34. PHONES/CTRL ROOM CONTROL: Use this control to adjust the control room output level
and the headphones volume.
