The Radial J48 has been designed from the ground up to deliver the most natural tone. As a direct box manufacturer, we do not believe it is our task to alter the sound of your prized ‘1962 Fender Jazz Bass’, but retain and transfer the true character of the instrument to the mixing console without adding distortion or introducing artifact. This design philosophy has gained a tremendous following from many of the world’s most demanding musicians.
Using only 48V phantom power, the Radial J48 is an active direct box that produces an exceptionally linear response that extends from 20Hz up to well above 40kHz. Low distortion of all types is achieved via a unique digital switching power supply that raises the internal operating rail voltage for added headroom and improved signal handling. The results are truly amazing. The J48 delivers an ideal even-order harmonic cascade and a sonic performance that outperforms DIs costing several hundreds more.
And like all Radial products, the J48 is both feature-rich for studio and made tough to handle the road. This includes a -15dB input pad to tame extra loud signals, 180º polarity reverse for feedback control on stage and a ground lift to help reduce hum & buzz caused by ground loops. Special features include a merge function that elegantly mixes left-right signals to mono without phase cancellation. To minimize resonant feedback with acoustic instruments, the J48 is also equipped with an 80Hz high-pass filter (low-cut). When engaged, this also increases headroom by eliminating unneeded bass frequencies.
Radial’s innovative book-end design protects switches and connectors from abuse while the internal I-beam construction eliminates stress on the PC board. This serves to reduce solder joints from going ‘cold’ and delivers trouble-free performance for years. A full-bottom no-slip pad provides mechanical and electrical isolation while providing plenty of ‘stay-put’ for rockin’ stages!
The Radial J48 is used by artists as diverse as acoustic guitarist Tommy Emmanuel; super-star engineer Joe Chiccarelli; and one of the most successful bands of all time Fleetwood Mac. The Radial J48… the world’s finest 48V phantom powered active direct box.

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.
The alphaton Direct Injection-Box SM-50 allows direct connection of electric guitars,
electric bass, and electronic music instruments with mixing desks of PA systems
and of recording studios.
The SM-50 reduces the amount of microphones used on stage, thus improving gain
before feedback.
Coloration of sound is avoided. Clean signal without interference from other instruments
eases the job of the recording engineer. The use of a strong aluminium die-cast box allows
trouble-free function for a number of years even under adverse conditions. Double grounding
(hum) can be eliminated by activating the built-in ground-lift switch. Isolation voltage between
input and output is 2500 volts, against ground 1500 volts (with ground-lift switch activated).
The box thus complies with toughest safety standards.

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.

DOD AC 275 Active Direct Box with Switchable Ground Lift and Attenuator-2nd Hand-
The AC 275 is an active, phantom powered direct box. Unlike a passive DI where the frequency response of the signal can be altered depending on the connected impedance, an active DI buffers the input signal with an amplifier. This assures that the sound source will reach the mixer balanced and noise-free.
Housed in a cast alloy chassis, the AC 275 supplies two, high impedance, unbalanced 1/4" jacks and one low impedance balanced XLR jack. It operates with battery or phantom power.
Key Features

Active direct box
?
Allows a hi impedance unbalanced source to directly feed a low impedance balanced input
