Passive Summing solution without compromises

What does a mixer do?

A summing mixer blends the audio signals coming from DAW interface / sound card and from musical instruments. It then sends a combined and polished output signal on to loudspeakers or a recording system.

When mixing on a computer, many prefer to sum the tracks in the analog domain, which can result in more depth of field and a wider, more defined stereo image. I hear phrases like “more depth and separation,” or “more rounded/warm low end”, bass is round and fat, middles are intensive but pleasant, trebles are nice and silky.

Mixers perform 3 main functions: level balancing of multiple audio streams (level controls or faders), spatial placement (panning) and summing the audio to stereo. A summing amplifier simply sums multiple audio streams to stereo, while the DAW’s mixer is used to perform the mixing functions of balancing and panning. (gearslutz)

“Really cool passive analog summing box. Really well made. Noiseless, infinite headroom and no power required. The best way to mix outside the computer, enjoy clip free summing and then use the mic pres of your choice to send your mix back to your DAW. ”

“Things are a lot sweeter! Compared to the previous mixes this overall sound, including the vocal, is like milk and honey! Overall with better balance and natural tonality. The sound has very nice dynamics and impact. It’s a total transformation. Good clarity, instrumental balance, stereo image. Bob Katz”

Customer review feedback

I was considering the Rolls 16 ch passive summing mixer but on Ebay, I discovered Paul Taylor’s Vintagemaker products. I emailed him to ask some questions and found his response to be positive and quick. I asked him to build me a 24 ch passive summing mixer with the insert feature and 8 chs of mono/stereo (switchable). He made and delivered the unit within 2 weeks (most of that shipping time was in customs in NY).

He sent pics via email and regular updates as the unit was made.

I plugged it into my studio, 1–24 Pro tools (Outs) and found the Neve 1272s to be the best sounding pre amps for the 2 buss on the mixes I was working on. the TubeTech MP1A also sounded great, the Focusrite was nice and the APIs were ok, too.

My REVIEW: Clarity and Glue. It clearly sounds better than in the box summing, but you all knew that would be the case. It also sounds better than the AMEK console that I had been using for summing mixes. I had sold the console and this was one of the replacement parts. I am Very Happy. I would highly recommend Paul Taylor’s custom built products. he was easy to deal with, great communication and ultimately a great sounding box that let me interface the preamps I already have as the 2 buss. A serious upgrade for a box that is reasonably priced for what it does. I would love to hear the other active summing mixers that he makes, but for now, I am a happy studio owner with the box he sent me. Thanks, Paul.
