Sound Pure's Take

When Chris Muth and the Dangerous Music team launched the original 2-Bus, they virtually invented the active analog summing category. With the Dangerous Music 2-Bus+, they took that legendary, high-headroom foundation and built the ultimate analog summing engine for modern hybrid mixing—combining pristine audiophile summation with custom analog color circuits you can dial in with precision.

At its core, the 2-Bus+ is a 16-channel active analog summing mixer designed to solve the spatial collapsing, lack of depth, and digital harshness that can happen when summing complex mixes entirely inside a DAW. It provides massive analog headroom and vast channel separation, giving your mixes three-dimensional width, a rock-solid center image, and effortless punch.

What makes the 2-Bus+ an absolute game-changer over traditional summing boxes is its three switchable analog processing circuits:

  1. Harmonics: A subtle odd-order harmonic distortion circuit that adds classic analog tape-like warmth and presence.

  2. Paratone: A parallel FET limiter circuit inspired by vintage aggressive limiting—perfect for adding weight and energy without squashing transients.

  3. X-Former: Custom-wound transformers with a core-saturation control that injects authentic console punch and low-end authority.

With flexible routing that allows you to assign these color circuits across channels 1–8, channels 9–16, or the main stereo bus, the 2-Bus+ gives you complete creative control over where and how much analog mojo you apply to your mix stems.

From Dangerous Music

Dangerous Music invented the stand-alone analog summing mixer with the ground-breaking 2-BUS back in 1999, and now we’re redefining mixing yet again with the brand new 2-BUS+. With a redesigned analog summing circuit that exceeds previous specifications, the 2-BUS+ delivers unsurpassed imaging, dimensionality, punch and headroom. While the 2-BUS+ active summing sounds incredible on its own, it now includes three innovative custom color circuits that provide a vast array of flexibly routed tonal options. Harmonics is a euphoric odd- and even-order distortion generator; Paralimit is a hard-hitting FET-style limiter; and X-Former is a pair of Cinemag output transformers with an exclusive core-overdrive circuit. With it’s elegantly straightforward buttons and knobs, the 2-BUS+ puts endless combinations of robust analog sound at your fingertips. Meticulously developed by our hands-on team and brilliantly designed by the legendary Chris Muth, the 2-BUS+ embodies our dedication to sacrificing nothing in order to deliver the very best analog products available.

When it comes to adding analog color to your mixes, the design team at Dangerous has developed three totally original all-analog circuits: Harmonics,Paralimit and X-Former. Because these circuits are physically built into the 2-BUS+, you get a versatile selection of analog colors while never leaving the lush, open analog mixing environment.

Harmonics 

Add the euphoric sound of an analog circuit on the edge of distortion to your whole mix, or to individual channel pairs. Carefully tuned to generate the perfect mixture of odd- and even-order harmonics, this effect runs parallel with the unprocessed signal so you can dial in just the right amount of tone. The top end subtly simmers, the bass gently growls, and the whole sonic image warms up in ways that only a real analog circuit can offer.

Paralimit 

This is a FET Limiter set to stun. An original Chris Muth design inspired by the famous 1176 Limiting Amplifier “all buttons in” trick, you get an infinite ratio setting flooded with analog top-end. With its blend knob and assignment buttons,Paralimitgives you instant parallel compression, in stereo, in the analog domain, on the full mix or on a stereo stem – a flexible set-up that otherwise requires complex patching, careful level matching and significant amounts of analog outboard gear.

X-former 

Last in line are a pair of customized Cinemag transformers with Chris Muth’s totally unique approach to driving the core. Switch them in for the solid, punchy sound that makes older analog consoles so loved, then turn up the X-Former knob to drive the core of the transformer in a way that’s totally unique to the 2-BUS+. X-former is all about dialing in just the right amount of classic analog console color whenever it’s called for.
