Elite Acoustics Stompmix X4 Pedal Mixer

This device has so much features packed in a very solid housing: It has phantom power for the mic inputs, polarity flip per channel, a very nice sounding reverb, notch filter, highpass, very usable EQ and an excellent sounding compressor.

Unfortunately the general noise levels are really too high, especially with phantom power enabled. When you use microphones with a very strong signal and when the gain boost is totally disabled the noise is still very audible. I also tried different power supplies with isolated clean power, but this doesn't make a difference.

So it's too bad. If this would have a much lower noise floor I'm sure it will sell like hotcakes. Hopefully with a new revision?

I use this mixer for very specific projects. The biggest pro is obviously the small form factor. Further plusses are the build quality and the well placed buttons. Cons are the menu structure, I still find myself pressing the wrong button several times, even after years of use. Biggest con for me is the lack of XLR out, which makes it necessary for me to use a supplementary DI. It kind of undoes a part of its small form factor for me.

I was looking for a solution to reduce the size of my rig for solo gigs and open mics. I needed a mixer ideally that fitted on my board with 4 inputs and had onboard effects.
The Gigmix version was a possible but what made me decide on the Stompmix was the ability to use a couple of condenser mics with the 48v phantom power for acoustic gigs.

There is a small but functional colour display in the centre of the pedal surrounded by multifunction knobs and buttons. It took me about 5 minutes to figure it out without looking at the manual.

All channels have reverb, EQ, pan, compressor, gate, notch, filter and phase invert. Only one channel can have delay applied at any one time which for me is on the vocal mic channel.

It has 2 main outputs (L&R) that are standard TRS that I run to a couple of Bose S1’s. There is also a 3.5mm headphone / stereo output which is the aux mix output. So if you have a couple of small powered monitors in stereo with a “Y” cable you can get a well balanced sound on stage. The only con with the Stompmix and Gigmix is there’s no reverb on the aux mix but as the delay IS present in the aux mix it’s not a big deal. Just to note, there is also a pan control for the aux mix so you can get a nice separation/ stereo image in your monitors.

Bottom Line
Great sound, very intuitive controls, all the parameter adjustments you need to get a polished mix very quickly through any FOH in a strange venue. I would definitely recommend this small, very well built unit to anyone.

Note - 18 months later - the output jacks are giving intermittent output. The unit hasn’t been abused and lives on my board. In my opinion there needs to be locking nuts on the jacks where they go through the side of the assembly. Although I haven’t looked inside so I don’t void warranty, it appears the jacks may just mount directly onto the PCB. If this is the case, every time jacks are plugged in, the solder joints will be stressed. Going back to Thomann for repair.
