Frequently Asked Questions - SX3204 SOUNDCRAFT

How do I connect a microphone to the mixer?

Use a balanced XLR cable to connect the microphone to any of the 32 mono input jacks. Ensure phantom power is activated if required by the microphone.

How can I route signals to the main outputs?

Press the 'Main' assign button on each channel strip. The signal will be sent to the stereo main L/R bus, which can be controlled by the master fader.

What is the function of the AUX sends?

AUX sends allow you to create separate mixes for monitors, effects, or recording. Adjust the AUX level on each channel to send signal to the corresponding AUX output.

How do I use the built-in effects?

Connect an effect send to the internal effects processor via the dedicated send/return. Select an effect type using the onboard controls and adjust the mix level.

Can I record directly from the mixer?

Yes, use the REC outputs (typically RCA or TRS) to connect to a recording device. Alternatively, use the main outputs or group outputs for multitrack recording.

How do I activate phantom power?

Phantom power is switched via a global or per-bank switch on the rear panel. Press the +48V switch to enable for the corresponding bank of channels (e.g., channels 1-8).

What should I do if the mixer does not power on?

Check the AC power connection and ensure the power switch is on. Verify that the internal fuse is intact (accessible near the power inlet). If the problem persists, contact service.

How can I clean the mixer?

Use a dry, lint-free cloth to wipe the surface. For stubborn dirt, slightly dampen the cloth with water (do not use solvents). Avoid moisture entering any openings.

What cables are recommended for connecting instruments?

For balanced connections (microphones, balanced line signals), use XLR or TRS cables. For unbalanced instruments (e.g., guitar), use TS (tip-sleeve) cables and DI boxes if needed.

How many channels can I use simultaneously?

You can use all 32 mono channels simultaneously. Each channel includes a 4-band EQ, mute, solo, and routing options.

1.2 ADVICE FOR THOSE WHO PUSH THE BOUNDARIES

Although your new console will not output any sound until you feed it signals, it has the capability to produce sounds which, when monitored through an amplifier or headphones, can damage hearing over time.

Please take care when working with your audio — if you are manipulating controls which you don't understand (which we all do when we are learning), make sure your monitors are turned down.

Most importantly — don't be afraid to experiment to find out how each parameter affects the sound — this will extend your creativity and help you to get the best from your mixer and the most respect from your artists and audience.

3. SX SERIES CONTROLS

3.1 OVERVIEW

3. SX SERIES CONTROLS

3.2 FRONT PANEL

1- PHASE SWITCH(EXCEPT FOR CH21/22, 23/24)

This switch allows the user to invert by 180 the signal. This switch is very useful in a lot of circumstances, in particular when several microphones are very close (e.g. Drum kit, brasses, chorus, etc.) And the sound engineers notices interferences between microphones that can not be solved moving the microphones.

2- LOW-CUT BUTTON

By pressing this button, you will activate a 75Hz low frequency filter with a slope of 18 dB per octave. You can use this facility to reduce the hum noise infected by the mains power supply, or the stage rumble while using a microphone.

3- GAIN

The GAIN control is applied in the mono MIC and stereo input channels. It provides with 2 different indications: One is for the MIC and the other for LINE levels. When you use a microphone, you shall read the MIC ring (0\~50 for mono MIC input, 0\~40 for stereo channels); when you use a line level instrument, you shall read the LINE ring (+15\~-35 dB for mono MIC input, +20\~-20 dB for stereo channels). For optimum operation, you shall set this control in a way that the PEAK LED(15) blinks only occasionally in order to avoid distortion on the input channel.

4- LEVEL SET LED

This LED will help you to detect the input level immediately. In this case, the research of the fault will become much faster!

5- LINE/MP3 BUTTON(CH 21/22)

By pressing this button, it will switch to the MP3 mode, the MP3 signal can be sent to this channel. By releasing this button, the LINE IN inputs signal will send to the input channel.

6- LINE/USB BUTTON(CH 23/24)

By pressing this button, it will switch to the USB mode, then the USB signal can be sent to this channel; by releasing this button, the LINE IN inputs signal will send to the input channels.

EQUALISER

There are 2-band fixed and 2-band sweep EQ on mono channels: HI, MID-HI, MID-LOW and LOW. There are 4-band fixed EQ on the stereo channel HI, HI-MID, MID-LOW and LOW band.

7-HIGH

If you turn this control up, you will boost all the frequencies above 12 kHz (shelving filter). You will add transparency to vocals and guitar and also make cymbals crispier. Turn the control down to cut all frequencies above 12 kHz. In such way, you can reduce sibilance of human voice or reduce the hiss of a Tape player.

8- MID-HI(0.5-12K) & MID-LOW(80-2K)

This is a peaking filter and it will boost/cut frequencies from 100 Hz to 8 kHz depending on the position of the MID freq control. This control will affect especially upper male and lower female vocal ranges and also the harmonics of most musical instruments.

9-HI-MID

This control gives you up to 15 dB boost or cut at 3 kHz. It is useful for controlling voice. It can accurately polish your performance via adjusting this knob.

3. SX SERIES CONTROLS

10- MID-LOW

This control gives you up to 15 dB boost or cut at 500 Hz.

11-LOW

If you turn this control up, you will boost all frequencies below 80 Hz. You will give more punch to bass drum and bass guitar and make the vocalist more "macho". Turn it down, you will cut all the frequencies below 80 Hz. In this way, you can avoid low frequency vibrations and resonance thus preserving the life of your woofers.

12- EQ SWITCH

This switch allows the user to use the EQ Section in signal path. Of course it can be used to make A/B comparisons between equalized signal and not equalized signal. It also can be used to apply equalization at a certain point of the show, excluding it when it's not necessary.

These six controls are used to adjust the level of the respective signal sent to AUX bus, AUX-1,AUX2, AUX3,AUX4,AUX5,AUX6 can be switched to PRE/POST-FADER via the PRE/POST button, so, generally, they can be used for monitor application and effects & sound processors input. In this typical compact unit, excluding sending out the signal directly to the external effect or processor equipment, AUX SEND 5&6 can also be assigned to the internal onboard effect module.

14-PAN CONTROL

Abbreviation of PANORAMA control for mono channels, or the stereo channels, always says, BALANCE control. Keep this control in center position, then the signal will be positioned in the middle of stage.

15-PEAK LED

Inside your SX series, the audio signal is monitored in several different stages and then sent to the PEAK LED. When the LED is red illuminated, it warns you that you are reaching signal saturation and possible distortion, then you should reduce the input level for avoiding distortion.

16-MUTE BUTTON & LED

Each channel is equipped with a MUTE button. Pressing this button is equal to turning the fader down, which can mute the corresponding channel output except for the channel INSERT send and SOLO (in PFL mode). And the MUTE LED will illuminate.

17-FADER

This fader will adjust the overall level of this channel and set the amount of signal send to the main output.

18-ASSIGNMENT Controls

Each channel provides four push-buttons: SUB1-2, SUB3-4, MAIN L-R, CENTER and SOLO. Pressing the SOLO button, the corresponding SOLO LED will illuminate and the SOLO signal will replace other signals send to the Headphone/Control Room and Meters. Usually use the SOLO function in live work to preview channels before they are let into the mix.

It is useful to set an instrument's input level and EQ, and you can also solo any channel that you want to. The SOLO switch never affects any mix other than the Control Room. The other three buttons can be considered as signal assignment switches.

Pressing the SUB1-2 will assign the channel signal to Subgroup1/2, you can depend on the PAN switch to adjust the amount of channel signal sent to the SUB1 versus SUB2, when turns the PAN to completely left, then the signal can be only controlled by Subgroup1 and vice versa. In the same way, pressing the SUB3-4 or MAIN L/R will assign the channel signal to Subgroup 3/4 or MAIN MIX L/R, and will also be affected by PAN.

3. SX SERIES CONTROLS

19- MASTER AUX SENDS CONTROLS

These six controls are used to determine the master AUX SEND levels, which can be varied from -∞ to +15 dB. When the external effect units which have no input gain control were connected to mixer, you can get a further +15 dB gain available from these AUX Send outputs.

20- SOLO Button

The function of these SOLO buttons are the same as the channel SOLO button, they can also be affected by the SOLO MODE switch. Press the SOLO button, the corresponding AUX send will be routed to the Control Room/Phones outputs and Meters display.

21- MASTER STEREO AUX RETURNS CONTROLS

These four controls set the level of effects that received from the stereo AUX RETURN connectors, which can be varied from -∞ to +15 dB. They are used to provide the further gain for low level effects.

22- TO AUX SEND1/2

The both rotary knobs assign the AUX RETURN signals to their respective AUX SEND outputs: The "TO AUX SEND1" assign the signal from AUX RETURN1 to AUX SEND1 bus, and "TO AUX SEND2" assign the signal from AUX RETURN2 to AUX SEND2 bus. The adjustable range goes from -∞ to +15 dB.

23- SUB1-2/SUB3-4/MAIN L-R/CENTER BUTTONS

These two groups of buttons are configured for AUX RETURN3/4, they can be regarded as the signal assignment switches. For example, When engaging the SUB1-2, the stereo signal from AUX RETURN3 will be assigned to Sub-group1/2; In the same way, SUB3-4 for Subgroup3/4, MAIN L-R for MAIN L-R buses.

24- MATRIX A&B

These controls will allow the sound engineer to address SOURCES SIGNAL to SUB1, SUB2, SUB3, SUB4, MAIN L, MAIN R, CENTER.

By rotate the knobs, you can adjust the stereo signals level of 2TK input and engaging the switch allows you to combine the 2-Track output with the Main Mix. In other words, feeds the 2-Track In signals into Main L/R output.

26- SUBGROUPS ASSIGN TO MAIN MIX

Through these switches, you can operate the subgroup faders as a master control for assigning the subgroups to MAIN MIX.

27- POWER LED

The LED indicates when the power is ON.

28- LED METER

The stereo 16-segment LED Meter will indicate the signal level send to the Control Room and Phones outputs.

29- SOLO ACTIVE

This LED indicates that the one or more SOLO button have been activated. When this LED is on, the METERS indicates the level of the signal of the selected channel or mixer section in AFL mode.

3. SX SERIES CONTROLS

30- SOLO MODE BUTTON

This button provides two modes: up for PFL (Pre-Fader-Listen) mode, down for AFL (After-Fader-Listen) mode. Engage the button, the soloed signal will output after the Level control, otherwise, release the button will output the soloed signal before the Level control.

NOTE: The SOLO function can never affect the mix at main recording output, and also can't be affected by channel's MUTE switch.

31- PHONES/CTRL ROOM CONTROL

Rotate this knob to adjust the stereo level of CTRL ROOM & PHONES outputs separately, which can be varied from - to MAX.

32- CONTROL ROOM SOURCE

You can choose to monitor any combination of MAIN L-R, SUB1-2, SUB 3-4 and CENTER via these Matrix switches. Engaging these switches, the stereo signals will be delivered to the Phones, Control Room and Meters display.

NOTE: When any SOLO switch was engaged, the SOLO signal will replace other signals, and also be sent to the Control Room, Phones and Meters.

33- SUBGROUPS FADER

These faders are used to control the levels of the signal send to the SUB-GROUPS OUT, the adjustable range goes from - to +10 dB. Any channel that is assigned to the subgroups, not muted and not turned down will be assigned to the SUB OUTS.

This fader sets the amount of signal send either to the Main Mix Output or to the Tape Output.

35- TALKBACK LEVEL

This is the main level control for the talkback section.

36- TALKBACK SWITCH

This switch activates and sends the talkback signal to its selected outputs.

37- TALKBACK SIGNAL ASSIGNMENT SWITCHES

AUX1-2,AUX3-4,AUX5-6 switches will allow the sound engineer to address the SOURCES signal to Auxiliaries. In this way you can send, e.g.,The Talkback signal to all stage monitors to communicate directly with performers while audience will hear

SUB1-2, SUB3-4, MAIN L-R, CENTER switches allow the sound engineer to assign the talkback signal to the audio path he wants to. The odd/even numbered switches are used to send the signal to subgroups (then you can send their signal to L/R outs) while L/R switch sends the signal directly to Main Mix.

3.3 REAR PANEL

1- +48 V PHANTOM POWER SWITCH

It is available only to the XLR MIC sockets. Never plug in a microphone when phantom power is already on. Before turning phantom power on, make sure that all faders are totally down. In this way, you will protect your stage monitors and main loudspeakers.

3. SX SERIES CONTROLS

5. WIRING UP

OK, you have got to this point and you are now in the position to successfully operate your SX series. However, we advise you to read the following section carefully to be the real master of your own mix.

Not paying enough attention to the input signal level, the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all. So you should follow this procedure for every single channel:

1. Turn down all Input and output gain controls.
2. Connect phantom powered microphones before switching on the +48 Volt phantom power switch.
3. Set the output level of your SX series mixer or the connected power amplifier at no more than 75%.
4. Now, set the CONTROL ROOM/PHONES level at no more than 50%. In this way, you will be able to hear later what you are doing connecting a pair of headphones or a pair of powered studio monitor speakers.
5. Position EQ controls on middle position.
6. Position panoramic (PAN/BAL) control on center position.
7. With a pair of headphone or studio monitor speakers are connected, apply a Line Level input signal so that the PEAK LED does not light up.
8. Increase the input gain properly for maintaining the good headroom and ideal dynamic range.
9. Depending on the actual application, turn slowly the input and output level controls for obtaining the maximum gain before distortion.
10. Now repeat the same sequence for all input channels. The main LED meter could move up into the red section. In this case you can adjust the overall output level through the main mix control.
