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.
Features:
Ultra low distortion of all types

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.

Active DI-Box SM-60
The electronic Direct-Injection Box SM-60 allows direct connection of electronic music instruments such as keyboards, synthesizers, electric and electronic pianos, etc. with mixing consoles in PA-systems and in recording studios. The SM-6 is designed for applications, where a passive DI-Box does not perfom satisfactorily, i.e., where the output level of a passive DI-Box is too low for the microphone input section of the mixing desk. Because the input impedance of the SM-6 is above 5 MOhm, instrument outputs are not loaded or in any other way adversely affected. The voltage ratio from input to output is 1: 1 and is always sufficient for connection with any microphone input. Input connectors are 1/4" phone jacks, output connector is a Switchcraft D3M; output is 600 Ohms, transformer balanced. The output level may in certain cases overload microphone inputs - the line input section of the mixing console must then be used for connecting the SM-6. The unit operates with a 9 V battery or phantom powering from 24 to 48 volts.

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.

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.
