7 INTRODUCTION Thank y ou for purchasing a Soundcraft MPM mixer . The MPM rang e 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 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.
9 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.
10 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.
11 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 12). • Get to know w hat all controls and/or connections in the system are supposed to do.
12 BLOCK DIA GRAM.
13 MONO INPUT CHANNEL 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 .
14 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 .
15 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 21). Aux 3 is alwa ys post-fade.
16 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.
17 7 F ADER The 60mm F ADER gives y ou smooth control of the o verall signal le vel in the channel strip, allowing precise balancing of the v arious source signals being mixed to the Master Section.

19 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 switch to enable the +48V pow er to all of the MIC inputs.
20 12 HEADPHONES SOCKET The PHONES output is a 3-pole 6.35mm (1/4") jack, wired as a stereo output, ideally for headphones of 200 Ω or g reater.
21 AUX 22 AUX MASTERS These three controls set the output lev els of the three Aux Outputs. 23 AFL These After F ade Listen switches route their respective aux output signal to the monitor/headphones out- puts.
22 USING Y OUR MPM 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.
23 • Repeat this procedure on other channels as required. As more channels are added to the mix, the meters ma y mov e into the red section. Adjust the o verall lev el using the Master Faders if necessar y . • Listen carefully for the characteristic sound of “feedback”.

25 APPLICA TIONS APPLICA TION 1 - LIVE SOUND REINFORCEMENT APPLICA TION 2 - MULTISPEAKER APPLICA TIONS This configuration demonstrates how multiple speak er configurations can be driven b y the EPM.
26 APPLICA TION 3 - PLACES OF W ORSHIP This configuration uses the A ux 3 output to driv e an induction loop for the hard of hearing . A ux 1 output is used to g enerate foldback monitoring for the speaker/sing er (A ux 2 could also be used for foldback but has been omitted for clarity).
27 APPLICA TION 4 - RECORDING The inser t points on channels 1-8 ma y be used to feed a multitrack recorder as shown (link the send and retur n signals).
