SAFETY REVIEW
The Exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying this product.
Certain precautions should be taken when using electrical products. Please observe the safety hints by reading the manual and
obtaining qualified help if necessary to adhere to the precautions.
1. Always use a properly grounded power supply cord with this product. Please do not defeat the ground pin on the mains plug.
This connection provides earth to the chassis and signal grounds inside the device for clean and quiet operation.
2. Avoid high temperature operation in equipment racks by providing air circulation. The number one killer of electronic gear
is HEAT. Vented rack panels may look like wasted space to an interior decorator, but they look like beauty to a technician or
equipment designer! If the front panel is hot, it is roasting inside the box.
3. Avoid areas of high magnetic fields. The steel chassis is designed to shield the circuits from EMI and RFI (magnetic and
radio interference). When installing equipment in racks, it is prudent to put power amplifiers and large power supplies at least
several rack spaces, if not in a different rack, away from equipment that deals with low level signals. Separation of high level
and low-level equipment can pre-empt trouble caused by heat and EMI.
4. Care should be taken to avoid liquid spills around equipment. If a spill occurs, please shut off the gear and disconnect the
mains. A qualified technician should investigate accidents to prevent further equipment damage or personnel hazards caused
by spills.
5. If one is uncomfortable with opening gear and changing jumpers or making adjustments, please seek qualified help if
necessary.
6. If adjustments or jumper changes are required, please disconnect the mains plug before opening the top. Dropped screws or
tools on a live circuit board can manifest themselves as burn marks and smoked components. While we feel your pain (been
there), subsequent damage is not covered by the warranty.

ABOUT DANGEROUS MUSIC
Dangerous Music builds award-winning, innovative pro audio hardware solutions relied
upon by the most discerning artists, producers, recording and mastering engineers
worldwide. Our converters, analog summing mixers, and outboard tools give you the
flexibility to craft a sound that is never overshadowed by the gear and is uniquely your
own.
Company co-founder Bob Muller states, “The ideas behind our gear are driven by
the needs of the musicians, engineers, and producers who form our community. The
rate at which technology is evolving means people are continuously adapting and
finding new ways to work in the studio. Dangerous exists to cut through the noise
and flatten the speed bumps. Early on, we concluded that once the smoke cleared it
was not going to be an all-analog or all-digital studio, but a hybrid environment. We
embrace the benefits of new technologies, but the inevitable problems that arise need
to be solved. As the analog console yielded to the DAW mixer as the focal point of the
control room, we recognized that certain essential equipment was missing in order to
make a studio fully functional, sonically compelling and ergonomically sensible. If you
aren’t spending all of your time clicking around computer menus, you can actually
concentrate on the music, the performance, and the rest of the creative elements of
what recording, mixing, and mastering should be.”

BACKSTORY
The Dangerous D-BOX+is a dramatic, ground-up redesign of the award-winning controller and summing mixer that provided countless studios the
superior sound and versatile control of an analog mixing console, all in just one rack space. The newly designed 8-channel summing mixer and D-A
stereo converters provide Dangerous Music’s bold and clear sound, while newly added features like USB audio, Bluetooth connectivity and an app for
remote control of all major functions unleash a truly forward-looking feature set. As with all Dangerous Music products, the D-BOX+is proudly made
to exacting audiophile standards in the USA.
How is this possible?
Out of dozens of options from our end users and the Dangerous Design Team, the most useful and requested options were incorporated into the
design, with sonic purity being prioritized over feature count. This comprehensive design was born out of Chris Muth’s design expertise and the
critical listening skills of top-tier audio engineers. Bon appetit.

“It’s obvious that Dangerous listens to their clients.
e addition of Bluetooth, a sub/3rd output and the
gloriously simple but complete app for my iPad takes
the D-BOX+to the next level of usability.e remote
talkback feature is the icing on the cake.”
RYAN WEST
Mix Engineer
OVERVIEW
1. GENERAL FEATURE SET
•8 channels of summing to restore your headroom, stereo separation, punch and dynamics.
•5 different input sources to monitor from including stereo analog, summing, bluetooth, usb and digital aes/spdif.
•2 powerful headphone outputs with 4 jacks (2 in front, 2 on the rear panel) to audition any combination of the 5 sources,
independently selectable from phones and ctrl room.
•Built in talkback, also available from the remote mic on your device via bluetooth.
•3 speaker outputs that may also be configured as two pairs of tops and a subwoofer. Speaker trims to unify their levels
with the option of mono listening.
•Dedicated line output that follows either the headphone or control room input source selection.
•3 volume options: regular, dim and set reference level that will always return to a fixed output upon your command.
2. PANEL FUNCTIONALITY
•MOMENTOGGLE & LATCH MODE
Feature: momentoggle is a feature built into all the buttons.
Benefit: If a button is simply pressed and released quickly, it will latch and remain engaged or disengaged. (Depending on whether it
was engaged or disengaged to begin with).
If pressed and held for more than a second, the function remains engaged (or disengaged) until the button is released.
Example: Want to dart between mono and stereo a few times quickly? Press it and hold. Or need to leave it in mono to see what’s ailing
the mix? Give it a tap.
Need to drop in the subwoofer for a second to see if that bottom end is the nervous guitarist tapping his foot against the mic
stand [press and hold] or for extended listening to determine if Romulan spacecrafts are landing? [tap and release]
Need to say, “rolling!” over the talkback mic to the talent? [press and hold] Or leave it open for a lengthy discussion between
the singer in the tracking room and the drummer in the control room about who has the sexiest lover. [tap and release]
Tip:,Be certain the talkback switch is not latched on when finished addressing the artist. For example: To the artist “Okay, we got
it.” To the second engineer “How are we going to get him to sing in key?” Click. Faah..

•INDIVIDUAL & ADDITIVE MODE
Feature: individual &additive mode functionality is built into all the buttons contained in the phones, ctrl room and speakers sections.
Feature: individual mode allows you to choose one selection at a time.
Benefit: For example, in the phones or ctrl room section, switch from iTunes/Tidal via usb and your final mix via aes/spdif and your
client’s rough mix via bluetooth. (This is the default setup.)
Feature: additive mode allows you to select multiple selections simultaneously.
Benefit: Select or deselect any combination of the buttons in each any of the phones, ctrl room and speakers sections to audition
more than one item at a time.
Example: Trying to track your guitar riff and emulate the vibe from the demo? Play the demo track on Spotify, iTunes, YouTube,
SoundCloud... via usb while monitoring your guitar riffing being recorded by your interface and back out through the sum
section. Match up a feel from a loop your client’s dropped on you via bluetooth while massaging the track around it real
time in your favorite DAW through the usb input.
Operation: Refer to setup mode section of this manual for detailed instructions on operation.
VOLUME KNOB / DIM / REFERENCE LEVEL
Feature: Adjustable volume knob, dim and reference level
Benefit: Adjust the level to your studio monitors on a contiguous knob or press it once and then spin it to audition the user
selectable dim level. Set a third option, reference level to jump to a fixed volume of your choice, by depressing the
volume knob twice quickly.
Operation: Refer to the setup section of the manual for details.
Tip:,If you want to set the reference level based on content coming from a specific input, select that input first, before
entering setup mode. Now you may listen as you adjust.
Rear Panel
3. SUMMING INPUT
Feature: Connect a DB25 connector here from the analog line outputs of your audio interface.
Benefit: Simple, elegant, common connector that is found on many other pieces of gear and patchbays.
Tip: ,The DB25 connector adheres to the Tascam Wiring Standard for 8 channels of balanced analog input. See the wiring
diagram in the appendix if you’re comfortable soldering, or just buy an excellent quality Mogami cable. (After all, you just
dropped a chunk of loot on d-box +and want all your electrons to dance down that wire perfectly).

“I love the app integration with the talkback mic
straight into the vocal booth, everything is adjustable
from my couch if I am being a writer or conducting
sessions I can control everything from my phone.”
KEVIN WILD
Producer, Songwriter
4. ANALOG INPUT
Feature: analog input may be set for +4dBu or -10dBV
Benefit: When plugging in an unbalanced, consumer level source like a headphone computer output, phone, DVD player, the level is
low (.315 volts vs. 1.23 volts), so set the input to -10dBV. For use with professional kit like converters, mixing consoles
, etc, set it to +4dBu. (This is the default status).
Operation: Refer to the setup section of the manual for details.
Tip: ,Inputs are dual combo jacks. They accept XLR, TRS (1/4” balanced) or TS (1/4” unbalanced).
5. AES/SPDIF DIGITAL INPUT
Feature: The digital input is on an XLR connector.
Benefit: Use either AES or SPDIF coaxial, just get a properly wired cable (i.e. RCA-XLRM)
Note: SPDIF = 75 ohms, AES = 110 ohms. The origin, not the destination, will dictate the whether to use SPDIF or AES. In
other words, if your interface is outputting SPDIF, then use 75-ohm cable. If it’s outputting AES, use 110-ohm cable.
Use: Take the digital output from your computer interface as an alternative to usb and connect it here to monitor through the
mastering quality D/A converter. This will provide an extremely accurate, yet musical representation of your audio that
will translate across multiple systems (i.e. iPhone, car stereo, home hi-fi, radio, club, 8-Trackª...) ª
Tip: ,See below and the appendix for images of all these cables.
•INDIVIDUAL & ADDITIVE MODE

10. SUMMING OUT
Feature: This is the stereo output of the 8 summed inputs.
Benefit: Hear your mix BEFORE it hits external processing or the A/D converter while returning back into your interface and DAW.
Switch between sources before and after effortlessly.
Note: summing out is always live. In other words, if signal is present at the summing input (green LEDs flashing), there will be
audio from the summing out unless the sum trim knob is fully counterclockwise at -∞dBu.
Note: The
sum trim knob has a swing of -∞dBu completely counterclockwise and unity when fully clockwise.
11. LINE OUT
Feature: This is the stereo output of the sources selected from either the headphone or control room section. (User selectable.)
Benefit: Send this output anywhere: to another headphone amp for expansinon or to the live room, so the talent can switch between
what sources they hear. Expand your monitor compliment by adding another monitor controller or hit a different A/D
converter for character comparisons. Even send it to your video camera for the audio capture... get creative.
Tip: ,Use the line out as a dub output. In other words, combine up to 5inputs simultaneously- analog, sum, bluetooth, usb and
aes/spdif. For a total of 16 inputs- that is slick, right?
Operation: Refer to sections 4 & 5.

13
12. SPEAKER OUTPUTS
Feature: Connect 3 sets of studio monitors or 2 sets and a subwoofer.
Benefit: Every studio should have at least two points of reference. Not all switchers are equal! The d-box +achieves this effortlessly,
without dropouts or phase shift. Remember... every decision you make while tracking and mixing is affected by your
monitor management system. That and the D/A are your only pieces of gear that are ALWAYS on.
Operation: See sections 7 & 8 for operation.
13. HEADPHONES OUTPUTS
Feature: Two independent source driven, powerful headphone amplifiers on the rear as well as the front.
Benefit: Select what to audition (one from the headphone selector and one from the control room selector). The talent and producer
may enjoy different source material. For example, the artist listens to the usb input while producer toggles between usb and
the rough track via bluetooth (feeling the performance inspiration). Potent amplifiers provide light years of headroom to
hear intelligibly while promoting intelligent decisions and driving the most inspired performances. Separate volume knobs
and sources will accommodate different user tastes, fulfilling the performer and producer’s needs while satisfy varying
headphone impedances. Please exhibit caution when selecting a level. You don’t get a second chance with blown hearing.
Operation: See the headphone jacks and level control knobs section for details.
Note: Here, the rear these jacks are multed in parallel from the front for wiring to a vocal booth or live room wall plate. They
can drive into 4-ohm loads, therefore you can use up to 8 pairs of headphones on each amp. (Assuming, that you are
using typical dynamic headphones that are each 32 ohms or higher.)
“e D-BOX+ is a signicant upgrade over the time
tested original. Engineers will be extremely pleased
with the new monitoring and cue section features. I
am getting great image and depth in my mixes from
the summing and the D/A is fantastic. e D-BOX+
has taken a quantum leap forward. ”
MIKE PICOTTE
Mixer, Engineer

Feature: Three pin IEC cable.
Benefit: Simple to replace if lost or stolen by a jealous bandmate.
Feature: Switching power supply auto detects voltage.
Benefit: Travel with your favorite gear anywhere in the world while spreading the audio truth.
Operation: Unit ships with voltage appropriate fuse value. To change it, use a screwdriver to gently pry the mains inlet module’s cover
open and insert the correct voltage. Fuses for the alternate voltage are included in the shipping box.
Tip: ,The power switch is on the inlet module. Seat the AC cable completely and use properly grounded power mains for safe
and quiet operation.
Tip: ,If the d-box +will not power on and the power is known to be good, check the fuses under the inlet module’s cover.
Use 2 amp slo-blow for 120V (America) and 1 amp slo-blow for 240V (Europe).
Front Panel
15. INPUT SELECT BUTTONS (ANALOG, SUM, BLUETOOTH AUDIO, USB, AES/SPDIF)
Overview: Think about it. You have the ability to monitor five different inputs. Digital and analog. In headphones and the control room.
Separate options for each. You can also send those out a dedicated line out.
Backdrop:Analog summing provides increased headroom and the sonic space required to achieve top flight mixes. Your digital
subgroups (or “stems”) are sent out of your session via your interface (D/A converters) to the eight analog summing inputs,
providing increased headroom, dimensionality and clarity. No more collapsing mixes from routing everything into a single
digital fader. You’ll benefit from precision panning, clear reverbs and delay tails, punchier bass, detailed mids and open top
end. Do you require even more channels of analog summing? Simply expand with the Dangerous Music 2-bus-lt or the
2-bus+.
Feature: The sum switch selects monitoring from the stereo summing mix output. (i.e. the summed combination of the 8 inputs).
Benefit: Hear your mix BEFORE it hits external processing or A/D conversion.

15
Tip: ,Run your final mixdown into the aes/spdif or usb input and toggle between sum and the final.
Feature: Both usb & aes/spdif buttons are digital inputs that feed separate (but equal) D/A converters.
Benefit: Monitoring from the same D/A allows mix decisions to be made, unbiased by different converters. Switch effortlessly from
the reference track playing on Tidal, iTunes, Spotify or YouTube through the USB to the your final mixdown connected via
aes/spdif.
Feature: Audition music from a bluetooth device.
Benefit: Fit of inspiration, client needs to share an idea, just some casual listening? Pair your device with the d-box+. (Refer to
bluetooth audio &remote control setup for iphone for instructions.)
Feature: The analog switch selects the analog input source from the rear panel.
Benefit: Connect all sorts of devices here! Samplers, synths, drum machines, an iPod, virtual instruments, a Sound Effects Library or
two track editor fed from an alternative computer output, a mixer or another summing mixer like a 2-bus-lt or the 2-bus+.
Tip: ,The input may be set to receive either +4dBu or -10dBV analog devices (see: the analog input section).
Note: This functionality is also available from your device (i.e. Phone, Tablet, Laptop...). See Remote Section.
16. HEADPHONES SELECTOR (INDIVIDUAL OR ADDITIVE MODE)
Feature: individual mode allows you to choose between five (yes, 5!) different input sources. analog (“analogue” if you’re British),
sum, bluetooth, usb and aes/spdif.
Benefit: Toggle between 5 input sources, one at a time. For example, switch from iTunes/Tidal via usb and your final mix via aes/
spdif and your client’s rough mix via bluetooth. (This is the default setup.)
Feature: additive mode allows you to select multiple input sources simultaneously.
Benefit: Select or deselect any combination of the headphone sources to audition more than one input together (analog, sum,
bluetooth, usb and aes/spdif). For example: trying to track your guitar riff and emulate the vibe from the demo? Play the
demo track on Spotify, iTunes, YouTube, SoundCloud... via usb while monitoring your guitar riffing being recorded by your
interface and back out through the sum section. Match up a feel from a loop your client’s dropped on you via bluetooth
while massaging the track around it real time in your favorite DAW through the usb input.

Note: There are three (3!) D/A converters in the d-box +. aes/spdif,bluetooth and... usb. Yep. usb is a digital language. Just sayin’.
*Note: usb input is plug-and-play when running Mac OS X. The driver will appear in the system window with d-box +followed by
your serial number. (See image below). For Windows systems, please visit our website for a link to download the correct
driver.
17. CONTROL ROOM SELECTOR (INDIVIDUAL OR ADDITIVE MODE)
Feature: individual mode allows you to choose between five different input sources. analog, sum, bluetooth, usb and aes/spdif.
Benefit: Toggle between 5 input sources, one at a time. For example, switch from iTunes/Tidal via USB and your final mix via AES/
SPDIF and your client’s rough mix via Bluetooth. (This is the default setup.)
Feature: additive mode allows you to select multiple input sources simultaneously.
Benefit: Select or deselect any combination of the headphone sources to audition more than one input together (analog, sum,
bluetooth, usb and aes/spdif). For example, trying to track your guitar riff and emulate the vibe from the demo? Play the
demo track on Spotify, iTunes, YouTube, SoundCloud... via usb while monitoring your guitar riffing being recorded by your
interface and back out through the sum section. Match up a feel from a loop your client’s dropped on you via bluetooth
while massaging the track around it real time in your favorite DAW through the usb input.
Operation: Refer to setup mode section for details.

18. SPEAKER SELECTOR (INDIVIDUAL OR ADDITIVE MODE)
Feature: individual mode select and audition one set of monitors at a time.
Benefit: Test your mixes on up to three sets of monitors toggle between them. (This is the default setup.)
Feature: additive mode select and audition multiple monitors simultaneously.
Benefit: Simultaneously feed your control room, lounge and live room (or any combination), to share the take or mix with the
artist. Or simply overwhelm your clients with sound, by latching up to three sets of monitors and playing them at the same
time.
Tip: ,The inset trim pots located beneath the LED section allow you to attenuate the levels of your studio monitors or subwoofer
(level matching), so they are all outputting at the same volume. Detailed instructions on this ahead under speaker trim.

19. SPEAKER SELECTOR CONTINUED (SUB)
Feature: sub link when choosing a set of monitors, the third monitor output may be dedicated to a subwoofer instead.
Benefit: Link a sub to your monitors, so every time you select them the subwoofer is activated (i.e. press speaker 2 and the sub
button turns on). Or choose to keep it independent for low frequency content checks. (The default is independent.)
Tip: ,Remember to utilize momentoggle. It is programmed into all of these switches. (Refer [not reefer] to section 3).
20. SPEAKER SELECTOR CONTINUED (MONO)
Feature: When choosing a set of monitors, the mono button has two possible behaviors:
[A] When unlinked in either individual mode or additive mode, the mono button will toggle on and off independently from
the speaker group. In other words, if you have the mono button engaged and move from speaker 1to speaker 2or 3, the
mono button will stay lit until you deselect it. (This is the default setup.)
[B] link mode tie the mono button to your monitors, so every time you select them mono is activated. (For example, if
you have a single monitor like an Auratone.) Press speaker 2 and the mono button turns on. Press speaker 1and the mono
button turns off. In this scenario, it can still be engaged for speaker 1, but it won’t remember to follow speaker 1 until you
program it.
Benefit: Want to do a phase coherency check for TV, broadcast and on-board mobile device playback? Press the mono button at
your discretion. (This is the default.) Have a single monitor (Auratone)? Program the button to follow that speaker set.
Operation: Refer to setup mode section for details.
Tip: ,Remember to utilize momentoggle. It is programmed into all of these switches. (Refer to section 3).
Note: 50% of the world still listens in mono- think about it. A “stereo” iPhone, playing through its speakers at 2” of separation
is mono (except for a mouse).
2 1. HEADPHONE JACKS AND LEVEL CONTROL KNOBS
Feature: Two independently assignable, powerful headphone amplifiers.
Benefit: Select what to audition- the talent and producer may enjoy different source material. For example, the artist listens to the
usb input while producer toggles between usb and the rough track via bluetooth (feeling the performance inspiration).
Potent amplifiers provide tons of headroom to hear intelligibly while promoting thoughtful decisions and driving the most
inspired performances. Separate volume knobs and sources will accommodate different user tastes, fulfilling the performer
and producer’s needs while satisfy varying headphone impedances. Please exhibit caution when selecting a level. (See tip)
Operation: First choose a source to monitor from, by depressing the appropriate input button from the phones and ctrl room section.
Then determine a moderate listening level via the volume knobs.
Note: These jacks are multed in parallel on the rear panel as well, for wiring to a vocal booth or live room wall plate. They can drive
into 4-ohm loads, therefore you can use up to 8 pairs of headphones on each amp. (Assuming, that you are using typical

19
dynamic headphones that are each 32 ohms or higher.)
Tip: ,Always start with the level control completely counter clockwise (minimum). The headphone amplifiers are very powerful
and there is no solution for destroyed hearing, even from the brain trust at Dangerous Music.
22. TALKBACK MIC & LEVEL CONTROL KNOB (HARDWARE)
Feature: Communicate with the talent via the built-in talkback mic directly into their headphones.
Benefit: Avoid figuring out a separate means of communication for the artist (i.e. sign language, megaphones, rock tossing, tea
leaves or hot yoga). Keep it quick, easy, and simple, thus encouraging the ultimate performance.
Operation: Hit the talkback engage switch. Starting at the minimum, gently increase the volume utilizing the level knob until the sweet
spot is achieved. More magic revealed about this switch in the next segment. (Hint: momentoggle.)
Note:When engaging the talkback switch, dim is automatically engaged; generally used to keep from blasting the control room
speakers into your talkback feed and looking like a tubhead in front of your clients. If you’re smart enough to know why
you should override this jump to setup mode section for details.
Tip: ,Always start with the level control completely counter-clockwise (minimum). You don’t want to be the cause of someone’s
hearing or inspiration loss.
Tip: , To create an isolated talkback output, choose one of the headphone outputs (front or rear) and assign nothing to it (i.e. No
bluetooth, usb, analog, summing or aes/spdif). Set talkback level and headphone level to taste. (Pretty fly!)
“Our goal was to beat the original D-BOX in both
sound quality and features, while riding the leading
edge of the computer-based recording studio. Oh, and
keeping it all 1 RU. It took a while, but I think we
nailed it.”

23. LINE OUT
Feature: Dedicated stereo line out that mirrors either the ctrl room or headphone source.
Benefit: The source or sources selected in either the ctrl room or headphone section will output here. Allowing you to send it to an
alternate destination. For example, front of house PA system, video recorder, House of Worship crying room, back into your
interface, mixdown device like a CD burner, iPhone or cassette deck- remember those? At least we didn’t mention a DAT
machine! (oops)
Tip: ,Use the line out as a dub output. In other words, combine up to 5inputs simultaneously- analog, sum, bluetooth, usb and
aes/spdif. For a total of 16 inputs- slick, right?
Note: These outputs are line level and unaffected by the speaker volume knob. (Identical operation from the free remote app.)
24. BLUETOOTH ENABLE
Feature: Activate or disable bluetooth functionality.
Benefit: Activate bluetooth audio and remote control or turn it off all together.
25. SIGNAL PRESENT LEDS
Feature: Eight signal present leds.
Benefit: Visual confirmation that the audio outputs of your interface are arriving at the d-box +.
26. SPEAKER TRIM 2 & 3
Feature: Attenuate the levels of your studio monitors with the inset trim pots.
Benefit: Level match your monitors (or subwoofer), so they are all outputting at the same or a balanced volume. Otherwise your
decisions may be biased by level, not reality.
Operation: This assumes your monitors have trim pots (a knob on the back for level adjustment). Turn down the volume knob of the
d-box +all the way. Whichever studio monitors are connected to the speaker 1 output of d-box +, turn the trims completely
counterclockwise and power off the right speaker. In your DAW (Pro Tools, Studio One...) locate a full-bandwidth pink
