Product Features: Professional and multi-purpose direct injection box for stage and studio applications Provides impedance and signal matching for the direct connection of instruments to mixers and amplifiers Ultra-flat frequency response due to renowned BEHRINGER OT-1 transformer Internal battery automatically shuts off when phantom power is applied Allows direct connection to speaker outputs with up to 3,000 Watts Switchable input attenuation allows input levels of up to +50 dB Ground Lift switch eliminates typical ground loop problems ¼" TRS and gold-plated XLR connectors Ultra-rugged, road-suitable aluminum case Stackable oversized rubber corners High-quality components and exceptionally rugged construction ensure long life and durability Conceived and designed by BEHRINGER Germany   With the DI100, you can rest assured that your sound source will reach the console balanced and noise-free. BEHRINGER's take on the all-important active DI box gives you functionality, durability and incredible sound at a remarkable price.
Be Direct
Plug into the DI100's balanced 1/4" TRS or XLR input, then send a signal to your console via the balanced XLR output. You can even plug your guitar or bass amp's speaker output into the DI100, which can handle ratings of up to 3,000 Watts and still deliver a perfect signal. It also features a 1/4" LINK jack to send your signal to an on-stage amplifier. The DI100 also has a switchable attenuation pad, allowing input levels of up to +50 dB. There is also a ground lift switch to eliminate noise associated with ground loops. The DI100 also features BEHRINGER's renowned OT-1 output transformer.
Superior Sound, Incredible Value
DI boxes are an essential part of any stage or studio, and the DI100 delivers the exceptional sound you expect, wrapped up in a rugged, road-proof aluminum case with stackable rubber corners.

Passive DI box. Jack input with paralell "THRU" output, transformer balanced XLR output. Attenuable input sensitivity, can handle both line level and speaker level signals.

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 dB10 dB12 is for you.

    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.
