Your Studio’s Centerpiece

The D-BOX is a transparent, audiophile-grade monitor controller for tracking, mixing and mastering with eight channels of Dangerous Music’s award-winning analog summing at an unbelievable price point. Legendary designer Chris Muth has developed a world-class circuit for the D-BOX that provides crystal clear fidelity and flawless performance across its flexible feature set. The D-BOX handles your input source monitoring, speaker switching, cue, talkback, headphone and mixing needs in just one rack space. The D-BOX hosts reference-grade D/A conversion, switchable analog inputs between balanced +4dBu and unbalanced -10dBV, two powerful 20w/channel headphone amps, a built-in talkback mic, and a stunning analog summing mixer that will give your mixes the headroom and sonic dimensionality needed to achieve truly professional results.

You Must Hear Everything

True craftsmanship is in the details. If you can’t hear the nuances of what you’re working on, then you simply can’t make informed decisions. Everything from placing a mic, to turning a knob on an EQ, to coaching a singer though a delicate passage depends on being able to hear exactly what’s going on. With the advent of “prosumer” gear, the monitoring path is typically sacrificed to meet a price-point, allowing what should be true craftsmanship to become guesswork. You simply can’t mix what you can’t hear. To solve this problem, the D-BOX incorporates audiophile-grade components in an unconditionally transparent design that reveals every last detail, allowing you to get things right the first time. Additionally, the D-BOX routes all your digital signals through the same onboard reference-grade digital-to-analog converter, giving you the same unified monitoring experience used by the world’s best mastering engineers. 

Hear Even More with Analog Summing

Our award-winning active analog summing provides the increased headroom and vast sonic space needed to achieve truly stunning mixes. With the D-BOX’s analog summing mixer, your digital subgroups (or “stems”) are sent out of your session via your interface’s D/A converters to the D-BOX’s eight analog summing inputs, providing incredible headroom, dimensionality and clarity. No more collapsing mixes from shoving everything into a single digital fader, with the D-BOX panning becomes precise, reverbs and delays more engaging and clear, bass punchier, mids more detailed and the top end more open. Require even more channels of analog summing? Simply expand with the Dangerous Music 2-BUS LT or the innovative 2-BUS+.

Effortless Signal Routing

As the centerpiece of your studio, the D-BOX handles all of your routing elegantly. There is the main stereo analog input, two digital inputs (both monitored through the same reference D/A), and two speaker outputs. The D-BOX handles both professional (+4dBu) balanced inputs and commercial (-10dBV) inputs (like phones and laptops) with easily programmed input levels. The on-board talkback mic and the dual 20w/channel headphone amplifiers with separate level controls round out all the routing needs for any studio.

Monitor Right and Never Guess Again

It would be hard to overstate the number of modern productions that have gone all the way to the final mastering stage with all kinds of noises, over-compression, clipping distortion and other unintentional problems because the monitoring chain was not revealing these issues. If you get your monitoring path right – as we have with the D-BOX – you’ll avoid the painful and time-consuming repair work required when problems are missed during production. Add in the D-BOX’s crystal-clear analog summing, and even the smallest project studios can have the best monitoring and mixing technology available in just one elegant and easy to use rack unit.

Why does the D-Box have an input labeled CD?

You can plug any digital device into this input, but we labeled it CD in order to give you an idea of one use for it. Most people like to reference their mixes against another mix (either their own or someone else's) so that they have a benchmark as to where they would like to go. The problem with this is that unless you are comparing the two mixes at the same level, through the same signal path, there is no way to accurately tell what you have to do to your tracks.

This is where the D-Box saves the day. If you plug a digital source (let's say the digital output of a CD Player) into the CD In on the D-Box, you can hear what it sounds like through the exact same circuitry that your mix is going through, giving you a more accurate comparison. Not only will the level of your reference be fixed, allowing you to compare it to the level of your own mix, but it will be played through the same D/A converter and monitoring signal path as your mix.

Why do playback converters matter?

D/A converters can greatly alter the sound of a source. Cheap converters can often greatly degrade the signal quality, making a track crunchy or muddy. Even expensive converters can sometimes be a problem for monitoring, because boutique and home hi-fi converters can make the material sound brighter or fatter than it actually is. When it comes to monitoring, what you want is a Mastering-Quality "Reference Monitoring Converter" like the one we have in the D-Box.  Basically what this means is that the converter is designed with the same philosophy as all of our analog monitoring gear- accuracy, transparency and neutrality. This allows you to make informed decisions on what to do to your tracks, because you are hearing exactly what's there.

Now imagine if you were to listen to the analog output of your cd player (or mp3 player, iPhone, computer, etc), through the cheap d/a converters that are built into this consumer-level device. The sound from the cd player that you are listening to will not accurately reflect what is really there in the track. When you compare your mix against this one, you are no longer comparing your mix to the true sound of the reference track, but to the sound of the track through this colored converter. This is not a proper way to reference your mix.

If you can hear both sources through the same Mastering-Quality D/A converter, however, you can feel safe in the knowledge that you are getting a true A/B comparison between the two.
