Soundcraft MFXi20

Soundcraft MFXi20

Soundcraft's MFXi mixers are compact and ideally equipped for live sound applications including fixed installations, houses of worship and portable PA.

8, 12 and 20 mono input MFXi mixers are empowered by built-in 24-bit Lexicon processing, delivering 32 stunning reverb, delay and chorus effects (see opening page). All MFXi mixers include 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, each model in the MFXi range 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 consoles use 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.

From Spring 2011 the appeal of the MFXi mixers is enhanced with the addition of a custom designed effect for Karaoke use; this preset was engineered by Lexicon and tuned with expert input from the Karaoke markets in Asia to deliver a great out-of-the-box solution for professional and casual Karaoke usage.

MFXi - MPMi: The Differences
MFXi input channels feature an FX send to the internal Lexicon effects processor, along with 2 Aux sends for use with external processors, or to create a monitor mix. MFXi consoles include an additional stereo return to mix with its own level control.
With no internal Lexicon effects, MPMi input channels replace the FX send with a third Aux send for operators preferring to use external effects.
