7 INTRODUCTION Thank y ou for purchasing a Soundcraft MFX mixer . The MFX range is our most cost- effective mixing solution, bringing y ou all the features and perfor mance that y ou expect from a Soundcraft product, at an extraordinarily low price.
8 THE 60-SECOND GUIDE 1 MIC INPUT (XLR) Connect Microphones here. If y ou are using a condenser mic, ensure phantom pow er is supplied by pressing the switch at the top of the master section. WARNING: Do Not apply Phantom P ow er before connecting a microphone.
9 12 PFL When pressed the signal will appear on the monitor and headphone outputs - use this to monitor the post-EQ signal from the channel. 13 MIX/SUB SWITCH When this switch is up, the channel’ s post-pan-pot signal is routed to the Mix (left and right) buses.
10 WIRING UP Mic Input The MIC input accepts XLR-type connectors and is designed to suit a wide rang e of BALANCED or UNBALANCED lo w-lev el signals, whether from deli- cate vocals requiring the best lo w-noise perfor mance, or dr um kits needing maximum headroom.
11 A ‘Y’ lead ma y be required to connect to equipment with separate send and retur n jacks as sho wn below: Stereo Inputs STEREO 1/2 These accept 3-pole 6.35mm (1/4") jacks, or 2-pole mono jacks which will automatically ground the ‘cold’ input.
12 Polarity (Phase) Y ou will probably be familiar with the concept of polarity in electrical signals and this is of par ticular importance to balanced audio signals.
13 PROBLEM SOL VING Basic problem solving is within the scope of an y user if a few basic r ules are follo wed. • Get to know the Block Diag ram of y our console (see pag e 14). • Get to know w hat all controls and/or connections in the system are supposed to do.
14 BLOCK DIA GRAM.
15 MONO INPUT CHANNELS 1 Mic Input The MIC input accepts XLR-type connectors and is designed to suit a wide rang e of B ALANCED or UNBALANCED signals. Professional dynamic, condenser or ribbon mics are best because these will be LO W IMPEDANCE. Y ou can use low-cost HIGH IMPED ANCE mics, but the lev el of background noise will be higher .
16 The Send ma y also be tapped off as an alter native pre-fade, pre-EQ direct output if required, using a lead with tip and ring shor ted tog ether so that the signal path is not interr upted (see below). 5 Gain This knob sets how much of the source signal is sent to the rest of the mixer .
17 POST -F ADE), but for Foldback or Monitor feeds it is impor tant for the send to be independent of the fader (this is called PRE-F ADE). A UX SENDS 1 and 2 are both globally switchable betw een pre and post-fade (see master section on pag e 20).
18 STEREO INPUT CHANNELS 1 INPUTS STEREO 1/2 These inputs accept 3-pole 6.35mm (1/4") jacks. Use these inputs for sources such as ke yboards, dr um machines, synths, tape machines or processing units.
19 7 MUTE All outputs from the channel are enabled w hen the MUTE switch is released and muted w hen the switch is do wn. The MUTE switch’ s inbuilt LED glo ws when the chan- nel is muted.

21 1 POWER INDICA T OR This LED lights to show w hen pow er is connected to the console. 2 PHANT OM POWER Man y professional condenser mics need PHANTOM PO WER, which is a method of sending a po wering voltag e down the same wires as the mic signal. Press the s witch to enable the +48V pow er to all of the MIC inputs.
22 12 HEADPHONES SOCKET The PHONES output is a 3-pole 6.35mm (1/4") jack, wired as a stereo output, ideally for headphones of 150 Ω or g reater.

26 REVERBS Rev erberation (or “reverb” for shor t) is the complex effect created by the wa y w e perceive sound in an enclosed space. When sound wav es encounter an object or boundar y , they don’t just stop. Some of the sound is absorbed by the object, but most of the sound is reflected or is diffused.
27 Reverse Reverb Rev erse reverb w orks in the opposite fashion from nor mal re verb . Whereas a normal reverb has the loudest series of reflections heard first that then become quieter ov er time, t.
28 Shape This control helps give a sense of both room shape and room size. Low v alues for Shape keep the majority of sound energ y in the early par t of the re verb tail. High v alues mov e the energy to later in the rev erb , and are helpful in creating the sense of a strong rear wall or “backslap.
29 increase the time between repeats. Range 0-72. See the Effects Data Char t for exact note v alues. Feedback Controls the number of dela y repeats by feeding the dela y output signal back into the dela y input. This creates a series of dela y repeats, each slightly attenuated until they become inaudible.
30 Knob 3: V oices Controls the number of additional Chor us v oices. Up to 8 voices can be added, continuously v ariable in 100 individual steps. Flang er This effect was originally created by simult.

33 USING Y OUR MFX CONSOLE The final output from y our sound system can only ev er be as good as the w eakest link in the chain, and especially important is the quality of the source signal because this is the star ting point of the chain.
