TEST: Soundcraft MFXi 12

 Although I have been involved with music technology of all kinds for several decades now, certain facts still give me pause for thought. Recently, it struck me again how dominant British consoles have become in terms of sound shaping. Especially in the early days of studio and live sound reinforcement technology, one could almost speak of a monopoly position.

Particularly when it comes to filters, "British standards" still apply today, from simple rehearsal room setups to the upper echelons of the few remaining high-end studios with corresponding facilities. And of course, one should not forget the characteristic preamplifier.

One of the big names from this era is Soundcraft. Active for over three decades now, the company, which now operates under the aegis of Harman International, is also opening up to smaller budgets without having to make too many concessions in the aforementioned references. As expected, this unfortunately no longer goes hand in hand with European manufacturing, but must be produced on the other side of the globe, in China.

With the MFXi series in the 12-channel version, I now have a small console for testing that sets out to follow in big footsteps in terms of tradition and sound.

## Construction

Even if one didn't know which country Soundcraft originated from, the "classic" British surface of the small console jumps out at you immediately after unpacking the test subject. Villa Kunterbunt at its best! Fully committed to British tradition, the optics indulge in the classic "color orgy", once again ruining the rather discreetly oriented sense of taste of the continental European ;-)

Potentiometer knobs vie for supremacy in the "colorful-as-colorful" contest with the colors yellow, red, pastel green, purple, light blue, black and white, all presented on a dark blue frame. Yes, that's how the British are, just as isolated in terms of taste as their currency and their little island on which they roam ;-).

The MFXi 12 is a 12-channel mixer that comes in an extremely compact package with dimensions of 482 mm x 94 mm x 405 mm and a weight of 6.7 kg. In addition to the twelve mono inputs, there are two additional stereo channels available for management. As a special feature, the product has an integrated Lexicon FX device, which has 32 memory slots. If needed, the mixer can also be rack-mounted using two side wings.

A mono channel strip is structured as follows:

- Mic: lockable XLR input for microphones or similarly low-level signals, all of which can be supplied with 48V phantom power if needed
- Line: balanced jack input for high-level signals such as drum machines, keyboards, etc.
- Insert: insertion point before the gain control in Y-configuration, typically used for compressor or limiter
- Gain: preamplifier control from 5 dB to 60 dB
- High-Pass Filter: low cut filter at 100 Hz, often used to reduce noise from wooden stages or finger-drumming noises of hyperactive singers
- HF: Shelving filter at 12 kHz with +/- 15 dB
- MF: Semi-parametric filter from 150 Hz to 3.5 kHz with +/- 15 dB at a Q factor of 1.5
- LF: Shelving filter at 80 Hz with +/- 15 dB
- Aux 1: fixed pre-fade, thus suitable as a monitor path
- Aux 2: switchable pre- or post-fade
- Fx: Level control for Lexicon FX
- Pan: Panorama control
- Mute: Mute switch with control LED
- PFL: Pre-Fade-Listening, signal is routed to headphones, control room outs and signal LEDs for pre-listening
- Mix/Sub: optional routing of the signal to main out or subgroup left/right
- PK: red peak LED, connected to pre-EQ, post-EQ and post-fade
- SP: Signal LED, indicates if a signal is present, pre-EQ switched

As expected, the stereo input channels lack XLR inputs, and there is no insertion point. They also feature a fixed mid-filter at 720 Hz, also adjustable by +/- 15 dB, with a Q factor of 0.8.

The master section has the usual control options of a console in this series, such as separate subgroup management and FX management. It's nice that despite the cramped space on the master control panel, thanks to "Villa Kunterbunt", you can assign the individual controls to their subordinate and superordinate functions in seconds.

On the rear, the console has only a very sparse equipment, which is limited to an IEC connector, an ON/OFF switch and a Kensington anti-theft device.

## Practice

It's tight on the console surface, that much must be said. Anyone hoping to be able to turn a potentiometer of the channel strips completely by 270 degrees with two fingers, with the exception of the gain control, will unfortunately be disappointed, unless they have extremely slim fingers like a model or stopped growing at the tender age of nine. Here you inevitably always bump into the adjacent controls, so you can only change your settings in 2-3 approaches. Well, not an existential criterion, but it annoys me like hell!

On the other hand, the controls run pleasantly stiffly, so that at least you don't unintentionally change the settings of the next pot again. At least that... Of course, you have to save on width to keep the 19-inch component in mind, but a little more depth would have worked wonders here. The general workmanship, however, is very good, there's nothing to complain about here. No wobbling, no jerking, no scratching, excellent.

In terms of preamp and filters, the MPXi 12 leaves a really good impression. Not that it completely blows you away in both sound groups, as you're used to from the large Soundcraft consoles, but for the price Soundcraft is asking, the components do quite remarkable things.

Once again, the Lexicon FX processor proves to be a real highlight. The spaces generated by the integrated effects unit are of high plastic density, great liveliness and know how to convince more than just for this price, respect!

## Conclusion

Nomen est omen! That's what Soundcraft must have said to themselves when they conceived the concept of the MPXi series. The task of bringing a good-sounding console to market as inexpensively as possible while not having to cut too many trademarks has been accomplished by the British company.

With the MPXi 12, the traditional company has created a small, flexible console that doesn't disappoint in terms of sound, scores in terms of workmanship, and comes with an excellent sounding Lexicon effects unit right from the start, for which you would have had to pay far more than half the console price for a hardware version not too long ago.

If it weren't for this cramped space on the control panel, you'd have to search hard to find fault with the product.

Handy, practical, good, a real Soundcraft indeed.
