Dangerous Music 2 Buss LT Summing AmpRegular price £1,350.00
Simpler Features, Same World-Class 2-Bus Components.
Searching for punch? Extended soundstage? Definition? Headroom? The Dangerous 2-Bus 16X2 summing device puts that all back into a lifeless mix. It functions as an audio bridge between the computer interface and analog outboard gear, allowing the best of both worlds to converge. Much like traditional vintage consoles brought together multiple channels of audio, the 2-Bus receives 16 analog outputs from any DAW interface and combines them to stereo. This is its sole purpose and it performs more transparently and musically than any other solution.
- Massive Punch and Detail
- Clear Stereo Imaging
- Effortless Outboard Gear Integration
- Analog summing for half the price of the original 2-Bus
- Full expandable with 2-Bus, 2-Bus LT, and D-Box
True summing devices have no individual volume controls, pan pots or aux sends. Those functions are performed by the recording software to leverage automation and recall on demand. Furthermore, running your audio through unneccesary electronics lowers performance.
The measure of a successful mix is consistency: will it translate across multiple mediums like the radio, an iPod, home hifi, a car stereo... Therefore, a summing solution must be transparent and musical to deliver. Only if and when color is desired, then outboard may be called upon for this purpose.
The 2-Bus LT was built upon the shoulders of the legendary 2-Bus. While build processes have been streamlined and costs reduced (i.e. DB25 connectors instead of XLR) the sonic result is virtually indistinguishable.
2-Bus vs. 2-Bus LT:

How It Works / Learn The Process
By routing individual mono tracks or panned stereo subgroups to the 2-Bus, you get the benefits of both analog tone and DAW automation. Route your elements out of the DAW via multiple converters, and build your mix from the ground up while listening through the 2-Bus. You will hear more detail, resulting in a better and faster mix.
The first thing you'll need to do within your DAW is to set up multiple hardware outputs from your digital-to-analog (DA) converters, and lose your software Master Fader. Replace the Master Fader with a stereo Audio Track named 2-Bus Mix. (Eventually, before printing the various mixes or stems, you will rename the "2-Bus Mix" track to reflect the song title.) Patch the main output of the Dangerous 2-Bus ("D2B") to a pair of analog-to-digital (AD) converters, i.e. Input 1-2, and set the input of "2-Bus Mix" to Input 1-2. Set this new stereo audio track to "input-monitor" so that you can hear the output of the D2B. This track is where you will record your mix.
Next you will need to route your individual tracks, returns and submixes to various DA outputs that are connected to the D2B's 16 inputs. Prior to mixing OTB, all your outputs within the DAW were probably set to Output 1-2, but that will no longer be the case. Assigning multiple outputs allows you to take advantage of the D2B's analog summing. Spreading your tracks across more DAs means that each DA has fewer elements to calculate, in layman's terms ensuring that each instrument or vocal has maximum DA power available to it.
At this point, you are likely to hear some of the benefits of OTB analog summing, relative to digitally summing ITB. But you've only scratched the surface of the possibilities!
You can expand your mixing horizons by using a patchbay to integrate outboard gear as a non-destructive insert between the DA and the D2B inputs, as well as between the D2B Main Out and your mixdown destination, i.e. 2-Bus Mix.
We'll illustrate two radically different stylistic approaches to routing. They are both equally valid, yet are capable of producing radically different aesthetic results. For the sake of simplicity, we'll call the two approaches "Hi-Fi" and "Power" routing.
The following is an example of an effective "Hi-Fi" routing for modern mixes when using a single Dangerous 2-Bus:
1. Kick Drum bus (mono)
2. Snare Drum bus (mono)
3. Drums bus (minus kick & snare) left
4. Drums bus (minus kick & snare) right
5. Bass bus (mono)
6. Lead Vocal (mono)
7. Background Vocals bus left
8. Background Vocals bus right
9. Guitar bus left
10. Guitar bus right
11. Keyboards bus left
12. Keyboards bus right
13. Horns & Strings bus left
14. Horns & Strings bus right
15. FX returns left
16. FX returns right
You can further control the submixes by adding EQ and dynamics processing to the signal path in between the DA converters and the inputs to the 2-Bus.
Here's a very basic example of an effective "Power" routing inspired by Michael Brauer's "Multi-Bus" mixing technique. Even an eight-input mixer like the one on the Dangerous D-Box can accommodate a simple, yet very powerful, version of this technique:
1-2. All Vocals stereo bus
3-4. All Bass & Drums stereo bus
5-6. All Guitars, Keyboards, Horns & Strings stereo bus
7-8. All FX stereo bus
The "power" of this particular routing is lies in the fact that you can easily "insert" stereo processing on each of the submixes in between the DA and the D2B. Thus you can optimize the processing for each group of vocals or instruments so that they will not be negatively influenced by the other groups.
Needless to say, you can mix and match the two routing approaches described above. Solve sonic problems or expand your creative horizons--the choice is yours.
Of course, you can adapt the routing to suit your needs, and you can seamlessly link any combination of up to eight 2-Bus or 2-Bus LT units to create a 128 in by 2 out analog summing mixer.
Documenting and precisely recalling your settings is a breeze, thanks to a stepped attenuator output control and colorfully illuminated "+6 dB" and "MONO" switches on the front panel.
Why should you care about analog summing?
Mixing “in the box”--aka "ITB"--has been noted by many users as having apparent limitations, which are commonly described as "lack of headroom," "poor spacial imaging," "loss of low level detail," and "inadequate preservation of transients." Much like traditional consoles brought together multiple streams of audio from a multi-track tape machine, the 2-Bus receives 16 analog outputs from any audio interface and combines them to stereo. It performs this transparently, without transient suppressing or bandwidth limiting components in the signal path, and is tooled specifically for the DAW environment. By spreading the track load across multiple digital-to-analog (D/A) converters and summing them in the analog domain, the 2-Bus delivers mixes that sound and feel as if they were mixed on a large-format analog console, without all the drawbacks that come with owning a console.
The 2-Bus system allows you to spread your DAW's workload across multiple D/A converters instead of using the internal stereo mix buss of the DAW (master fader.) Whether or not you choose to integrate analog outboard gear, this process distributes the workload over multiple converters, enabling each D/A or stereo pair of D/A's to dedicate its full potential to a single track or instrument, or a subgroup of just a few tracks. The final, ciritical step of summing to stereo occurs in the 2-Bus' high-headroom analog environment as opposed to occurring digitally in a computer. Transparent mastering-quality design and components preserve transient response and allow the artist or engineer to choose when, where, and how to color any individual track, stereo pair, or the entire mix with selected outboard gear without clouding the issue. If the summing amp itself has a lot of tonal coloration it is inherently limiting to the creative process, because if the color is not right for a particular project or song you cannot take it off. In short, the Dangerous 2-Bus is the right choice for you if you want to retain the purest, undistorted transient response, clarity and dynamics from your recording while maintaining the fast DAW workflow and recall capabilities required by today's mix specialists.
When is a "Summing Box" not a Summing Box?
The difference between a true summing device (or summing amplifier if you prefer) and a line mixer is that a summing device is designed as a true back-end for a DAW software mixer. It performs one very essential function: summing multiple channels of audio to stereo. A line mixer or console on the other hand performs several tasks- summing, level balancing (faders), spatial placement (panners), and aux routing of tracks. To put it simply, if it has a level control and/or a panner on the inputs it is a line mixer, not a summing amplifier. These functions are already happening in the DAW, so repeating them in the hardware domain on the back-end is detrimental for 2 primary reasons-
1. Instant Recall capability is lost.
2. Running your audio through unnecessary components compromises the signal path.
For these reasons, Dangerous summing amplifiers are the ideal devices for incorporating this hybrid process into your setup, whether it is a home/project studio, a travel rig, or a Grammy winning multi-room facility.
Why Do The Best Mixing Engineers Choose Dangerous Summing?
Top remixers like Junior Sanchez, Producers like Duncan Sheik, Charlie Peacock and Billy Mohler, and Platinum mix engineers such as David Kahne, Richie Biggs, and Michael James have told us that they rely on Dangerous summing as an integral part of their studios because it helps them "work faster, get better sounding mixes, easily integrate analog outboard gear without latency or extra A/D/A conversions, and improve workflow efficiency." Although they have very different approaches to creating world-class tracks, the 2-Bus is flexible enough to integrate seamlessly into each of their workflows: Kahne daisy-chains four units for a 64 x 2 mixer, with all his DAW outputs and his analog outboard gear permanently normaled together; James uses 2-Busses for pristine "uncolored" submixes that pass through analog processing en route to the final stereo mix. Sheik prefers the 2-Bus for it's transparency and its ability to let him work rapidly, and Mohler finally has the bass response he's been looking for with his D-Box's eight channels of summing. Whatever the scope of your needs, we have the right tools for you.
All summing mixers are not created equal. The Dangerous 2-Bus was the first and is still the best at what it does: restoring nuance, depth and clarity to your mix without leaving a heavy sonic thumbprint. The 2-Bus LT and D-Box carry on the legacy using the same great design and components with different feature sets to serve your personal needs and your budget.
