Summing Mixer with Insert and Monitor control output

Customer review

Just want to share my first impression of Little One 16 passive summing box with 2 x stereo to mono options.

I am just plain knocked.  If your tracking chain is good but mixes sound muddy, boxy, thin and narrow compared to big production hits that’s the remedy. Like everyone else i’ve noticed that mix is much clearer and wider, instruments more separated and focused. I also have noticed that i’m using less outboard and plugins. Seriously. If you choosing between good compressors or eq’s (good means ADL, SSL etc) vs good summing box (you would need audio interface to support that too) without hesitation go for analog summing – you won’t be dissapointed if you want your mixes sound 3d. Also box is quiet as a mouse. I was little afraid to pick some noise on the way. But no ! – it’s just way superior to digital bouncing and that’s all! 

10 input summing mixer with 2 x stereo to 4 mono, direct switch on 9/10 input to master out, master mono switch, -10/-30dB precision attenuator

Just a quick note to say how pleased I am with the summing mixer.

I’ve summed a piano session and a jazz session and all I can say is that it makes things sound finalised or complete! Its hard to put my finger on it. It’s like a sonic glue! There is definitely a stability that it adds. Sounds like a record! All the best! Alex

Gearslutz – Gearspace review

A few years ago I owned a Dangerous D-Box that had 8 channels of summing alongside monitor control. I liked it, because it gave me that little bit of extra depth and detail in my mixes that you get with analogue summing, but I ended up selling it when I stopped doing audio production full time. After a few years away from mixing I have recently got back into it and was looking around for a budget summing mixer. I don’t have the budget for expensive studio gear any more, but I kept all my ‘good stuff’, like monitors and interface from before. I saw Paul’s Vintage Maker site and read a bunch on passive summing and decided to get a LittleOne 16. The process of ordering was excellent, Paul provided all the information I needed in a direct, no nonsense way, and he built the unit and sent it within 2 weeks.

Once I plugged it in to my system I was immediately happy. The mix I had been working on now had that little bit of extra ’roundness’ and ‘depth’ that I was missing, and I could hear more detail in things like reverb tails that helped me finalize the mix.

The best thing about the LittleOne 16 is that I can run the output through different preamps to get different colouration. With the Dangerous D-Box I always thought it was a bit too ‘silky’ and ‘slick’ for my taste. I prefer my music and production to be more low-fi or 70’s sounding, so it’s fantastic to choose what you run your summed mix through to achieve the coloration you want. I’m not dissing Dangerous at all, their products are great quality and the D-Box monitoring was first class, its just the summing output wasn’t completely to my taste.

If you have a good quality stereo preamp to run this unit through to make up the gain, then get a Little One. You’ll be happy with the result.

My current production tools are; Pro Tools, UA Apollo Interface, Focal Speakers and some good quality preamps. I definitely hear a (good) difference
