The DN200 has become an established favorite amongst both engineers and musicians alike. With its high headroom, dynamic response and sonic clarity, DN200 faithfully reproduces the character of electric and acoustic instruments and allows far more of the detail of musical performances to be captured. DN200 is intended for professional applications where +48 V phantom power is a standard feature on all mixing consoles, and its innovative design results in a significantly higher clipping point than many other active DI Boxes, providing +10 dBu output into a 2 KΩ load. This increased headroom means that much higher-level input signals can be accommodated without the need for an attenuating pad. Combined with a very low noise input circuit topology, DN200 offers a very wide dynamic range, and only requires the -20 dB pad when connecting directly to instrument amplifier outputs or other very high-level signal sources.
DN200 is built to handle the rigours of life on the road, a thick aluminium extrusion protects the electronics, and in turn is protected by tough silicone rubber corners
Balanced Transformer-Isolated Output
Exhaustive listening tests using a wide variety of active and passive bass guitars, electro-acoustic guitars and electronic musical instruments were carried out to select the components for DN200 to achieve the best musical sound. Not only was the choice of the audio transformer particularly important in achieving this goal, but the impedances of the surrounding components were also highly critical in getting the best possible performance out of the audio transformer. The line-driving characteristics of the transformer output were carefully optimized to provide the best frequency and phase responses for short and long cables and widely differing line and termination impedances.
Care was taken in the design of the DN200 to avoid audio transformer core saturation and a fixed high pass filter has been included in the signal path to roll off frequencies below those that are musically important. The lowest note on a 5- or 6-string bass guitar is B0 with a frequency of 30.87 Hz, and the lowest note on an 88-key piano keyboard is A0 with a frequency of 27.50 Hz. DN200 still maintains a frequency response of ±0.5 dB at these lowest musical notes.
As well as the transformers in the signal path, DN200 also has a transformer to isolate the power rails to the input circuit from the phantom power supply sourced from the output XLR connector. When used in conjunction with the Earth Lift switch, this full galvanic isolation of input and output interfaces ensures that any risk of earth loops is avoided when taking a direct feed from stage backline equipment.
Dual-Impedance Stereo Inputs
A custom instrumentation-grade balanced input circuit was designed for the DN200 using advanced analogue design techniques to create the very high input impedance required by passive guitar and bass pickups, whilst keeping the actual component values low to minimize noise. This innovative approach to circuit design produces a very low noise floor, which combined with the high clipping point creates an unrivalled dynamic range in a +48 V phantom powered DI Box.
DN200 features dual parallel-connected combo XLR’s / ¼” TRS inputs. When connecting to the Combo XLR input, the input impedance is 20 kΩ, ideal for line level equipment and offering even lower noise performance. This input impedance is far too low for guitar and bass pickups and is removed from the circuit when a jack plug is inserted into the Combo ¼” TRS input, resulting in a nominal 1 MΩ input impedance, ideal for passive electric pickups.
DN200 is also equipped with a Stereo input mini jack which is ideal for connecting MP3 players or mobiles phones etc.
Illuminated 20dB Pad and Earth Lift Switches
DN200 features illuminated -20 dB Pad and Earth Lift switches. The Earth Lift switch separates the input and output grounds, useful in eliminating earth loops between equipment on different mains electricity supplies.
Illuminated Sum and Split switches
For added convenience the DN200 has illuminated Sum and Split switches which along with the +48V phantom power indicator LED’s, provide ‘at a glance’ status display even at wide distances and viewing angles. The Sum switch allows a stereo input signals to be combined into a mono signal which appears at both the L and R output XLR’s. The Split switch takes the L input and sends it to both the L and R output XLR’s.
The ¼” TRS Link Thru jacks may be used for a parallel input connection to a guitar or bass amplifier.
Built for the Road
Featuring a tough aluminium extrusion, the DN200 is designed for the rigours of live concert touring. The protective rubber corners also insulate the DN200 chassis to further enhance its electrical isolation. Premium Neutrik XLR connectors are used to ensure reliable audio connections, night after night.

With added functionality and enhanced audio performance, the AR-133 has been
designed to be more affordable for musicians, studios and PA companies.
The unit includes phantom power and battery supplies as standard. Should the
phantom power from the console fail or be accidentally switched off, the AR-133
automatically switches over to the internal 9V battery providing uninterrupted use.
The unit is housed in a rugged aluminium extrusion case, with robust polyurethane
end-cheeks which give the AR-133 a very distinctive look.
Input connectors are both 1/4" jack sockets and an XLR socket, the latter meaning
that the AR-133 can be used to convert unbalanced signals to a balanced output on
XLRs throughout.
The arched case allows cables to run back underneath the unit from the end for neat
cable management.
Input attenuation is 0, -20 or -40dB, making the box suitable for instrument, line or
amplifier levels on inputs. On the output side, a ground-lift switch is provided for quick
solutions to ground-loop problems.
The AR-133 uses an enhanced version of the same audio path as the AR-116, now
regarded by many people as a reference standard. The sound quality is legendary,
particularly on acoustic and bass guitars.
Numerous applications can be satisfied by the AR-133. For example, as well as the
traditional guitar use, the AR-133 can be used with keyboards, DJ consoles, amplifier
outputs, and other electronic sources.An additional bonus is the ability to use the AR-133
as an active balancing device.

At dbx, when we do something, we do it right. So when we decided to create our new direct injection boxes, we didnʼt settle for the same old tired approach to direct box design. With our dbx name on the line, how could we? One look at our new dB10 Passive and dB12 Active direct boxes will tell you that these are clearly different. With their bullet-proof construction, and extraordinary audio performance to rival their looks, finally thereʼs a direct box worthy of the dbx name.
Utilizing custom dbx mu-metal-shielded audio transformers, high-quality Neutrik® connectors, and low-noise circuitry preserves the sonic integrity and true characteristics of the signal source. Both boxes include a pad switch that accomodates instrument, line and even speaker level signals. Take even more control of your sound by utilizing the polarity invert switch to set the phase relationship between the direct and mic'd sound.
As a professional, you donʼt have time for interference, so weʼve included a ground lift switch to solve potential hum and buzz problems due to ground loops. And between the combined shielding of the cast metal chassis and the custom-wound transformer, you can be doubly assured of a clean signal free from interference. All of this sits atop a solid, stable footprint, that will keep the box from being dragged around the stage, and the unique contoured underside allows secure stacking of multiple units.
So whether you need to control the level, placement in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx dB12 is for you.
