Behringer DI-400P High-Performance Passive Direct Injection Box

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.

Tube-buffered DI-Box DI-1000
The Tube-Buffered DI-Box DI-1000 allows the extraction of all the musical details of musical interfaces without degrading the sound. This can only be achieved by providing a very high input impedance to avoid any loading of instrument pickups.This design approach allows seemingly infinite headroom to preserve the real dynamic range of the interfaced instruments.A vacuum tube enables all these goals to be achieved without any compromises in sound quality.The sonic difference between a standard DI-Box and the Tube-Buffered DI-Box is comparable to the musical resolution difference between a standard microphone and a studio microphone.One of the best transformers, the very transparent sounding JENSEN JT-DB-E, was chosen providing complete ground isolation. The parameters of this transformer, like frequency response, phase response, group delay and geadroom capabilities, play a vital part in the performance of this DI-Box.
Technical Specifications Input The signal of the instrument is directly fed to the tube circuit with > 20 MOhms input impedance to prevent any signal degradation, inevitable in traditional designs. Buffered Output“ The second stage of the vacuum tube is used to buffer the signal and lower the output impedance to < 8 kOhms. This unity gain output allows for cable runs of 10 meters without loosing high frequency information. Boost circuit The boost circuit increases the signal send to the output transformer by 15 dB. This may be useful for instruments with extremely low output, but decreases headroom capability to 6 Volt rms. Under these circumstances the signal may be clipped, concerning the output transformer?s signal, which gives you 2nd harmonic tube-like distortion. This distortion normally does not occur - but is sometimes desirable, being the reason for this special feature. Unity circuit The unity circuit feeds a low distortion unity gain signal to the JENSEN output transformer. This gives the best possible sound quality. Ground-lift“-Switch This front panel mounted switch allows complete ground and electrical isolation between the direct injection box and the console or recording 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.
