Soundcraft MFXI20

Soundcraft's MFXi mixers are compact and ideally equipped for live sound applications including fixed installations, houses of worship and portable PA. The 20 mono input MFXi mixer is empowered by built-in 24-bit Lexicon processing, delivering 32 stunning reverb, delay and chorus effects. The MFXi mixer includes 2 stereo input channels along with a 2-track record output and a 2-track replay input which allows interval music to be easily played from CD, MP3 or other music source.

For increased versatility, the MFXi mixer has two subgroups as well as a main stereo mix, making control of groups of channels much easier to manage. These are supplemented by 2 Auxiliary busses which can be used for effects sends or to provide a foldback monitor mix for artists.

The MFXi console uses vertically mounted PCBs which are secured with nutted pots for extra strength, stability and easy servicing. Well-spaced controls provide easy access at those critical control moments, enhanced by clear legending which highlights linked or associated functions.

Sound quality is assured by Soundcraft’s now-legendary GB30 mic preamp and the use of professional condenser microphones is facilitated by the provision of globally switched +48V phantom power. New circuit designs have improved audio quality, and lowered the overall noise floor of the console and FX sections. An integral universal power supply negates the need for an external power module.

The addition of a Kensington lock slot on MFXi/MPMi consoles provides a welcome level of security in installations.
