The Radial ProDI is a passive direct box that combines exceptional audio performance with solid dependable construction, making it the ideal general duty direct box for stage and studio. The heart of the ProDI is a custom wound Radial transformer. It features an exceptionally high 140kΩ input impedance to reduce loading while enabling the ProDI to handle extreme signal levels at all frequencies without distortion. This is further improved upon with an internal mu-metal shield to protect against electromagnetic fields that can cause unshielded transformers to distort.
This compact direct box begins with 14-gauge steel I-beam skeleton for added rigidity and Radial’s unique book-end design that creates a protective zone around switches and connectors. Glass filled nylon connectors and high cycle switches combine with the mil-spec PCB and internal RF filtering to provide durability and noise-free performance. A full bottom no-slip pad provides both mechanical isolation and electrical insulation to further protect against the rigors of professional touring.
The ProDI is ideally suited for instruments such as bass guitar, active acoustics, keyboards and just about anything else! When you consider all of the features and the affordable price tag, it is no wonder the Radial ProDI has become one of the most popular direct boxes ever made. The Radial ProDI… Spectacular performance at a price that anyone can afford!

Inline Transformer IA-2
The model IA-2 line matching transformers !S designed to properly match a low impedance signal to a low impedance source. The advantage of "ground lift" switching allows to optmize hum problems.
Technical Data Frequency response 20 Hz - 20 KHz + 1 dB Impedance 600 : 600 Ohm THD K3 50 Hz = 0.5 % Level < + 6 dBm Weight 100 g Dimensions diameter 17 mm, lenght 115 mm
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.

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.

Standard active DI box. Can be operated with 9 V batteries or 48 V phantom power. High-impedance input; higher output level than with a passive DI box. Active circuitry allows for high input impedance ( 1 meg. ohm) and higher input sensitivity (typical difference between in and out -4 dB). Maximum output impedance with phantom power operation +10 dB. Output: transformer balanced. The special "floating ground" circuitry enables ground lift even during phantom power operation. Metal case 110 x 73 x 42 mm.
