The Ultra-DI DI20 is an innovative active 2-channel DI-box/splitter that takes the signal directly from an unbalanced high-impedance output—like an electric guitar—and feeds it directly into a mixing console or recorder. It is ideally suited to augment the traveling gear of musicians (especially guitar/bass players) as well as live/studio/broadcast engineers, installation contractors and studios/live event engineers. The DI20 converts…

With the DI100, you can rest assured that your sound source will reach your console balanced and noise-free. Go ahead and plug that guitar amp's speaker output into the ULTRA-DI—it’ll deal with ratings of up to 3,000 Watts and give you a perfect signal at the other end. The input-buffering amplifier ensures clean, pure and powerful sound, even with extremely…

There are times when you will want to connect certain sound sources straight to other audio gear, be it for a live performance or a studio session. A direct connection between audio equipment can be a challenge though: technical problems crop up that’ll corrupt the signal. The DI600P lets you connect instruments or amplifier outputs of up…

There are times when you will want to connect certain sound sources straight to other audio gear, be it for a live performance or a studio session. A direct connection between audio equipment can be a challenge though: technical problems crop up that’ll corrupt the signal. The DI400P lets you connect instruments or amplifier outputs. It converts…

The Xdirect is a high quality interface that lets you connect instrument, line, or speaker level signals to a mixer or other balanced input. The high impedance single-ended 1/4” and XLR inputs are buffered and converted, by very low noise active electronics, into an isolated balanced low impedance signal source. The Xdirect has an extremely flat and wide frequency response…

The ULTRA-DI PRO DI800 is a professional mains/phantom powered 8-channel DI-box. It converts unbalanced line inputs into balanced outputs, featuring optional mains or phantom powered operation. Its servo balanced operation assures ultra-flat frequency response. Additionally, it allows direct connection to speaker outputs with up to 3,000 Watts. A ground lift switch as well as input attenuation/gain per channel round off…

Not every instrument is made to connect directly to a mixer. Guitars and basses have a lower output signal level, and their output is not balanced. If you plug them straight into a mixer, you have to jack the preamp level to the max just to get a quiet, wimpy sound. Most keyboards have unbalanced outputs, which means if you…

The Zdirect is a high quality totally passive interface that lets you connect instrument, line, or speaker level signals to a mixer or other balanced input thru a high performance audio isolation transformer. The high impedance single-ended 1/4” input is converted by the transformer into an isolated balanced low impedance signal source. The Zdirects audio transformer has an extremely…

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…

The DI4000 gives you four first-class DI channels in one rack space. With two inputs (XLR and 1 /4 " TRS), a balanced output (XLR) and a 1 /4 " link output per channel, up to 40 dB of switchable input attenuation and up to 20 dB of gain, the DI4000 is equipped to deal with virtually any input…

ULTRA-G GI100: Your secret weapon for direct sound. 

Whether you’re recording or on stage, you need a reliable DI box to get your guitar sound to the console with full dynamics and power—and without noise. Engineered for electric guitar, our GI100 features a switchable speaker simulation designed by Juergen Rath that so realistically emulates a 4 x 12" cabinet you…

Two channel, very high quality passive D.I. box, housed in the same all steel box used for our active models. It features a jack input socket, and link output for connection to an on-stage combo etc. Two wide band low distortion transformers provide a balanced 600 ohm output to an XLR. A ground lift switch is fitted, and the unit…

Adapting from Balanced to Unbalanced and Vice-Versa: Problem: You have a stereo output from a CD player (tape deck, VCR, computer sound card or other consumer electronics gear) and you need to connect it to the balanced line inputs of your mixer (EQ or other piece of professional audio equipment). Actually, there are three problems: 1.) Your source…

The Radial X-Amp is an active re-amping device that presents the engineer / producer with a new and innovative creative tool that allows a pre-recorded track from a line level device to drive two guitar amplifiers or effect pedals simultaneously. This opens the door to explore new musical sounds and spur on the creative…

The Radial ProDI's are high-quality, full-range passive direct boxes equipped with custom made audio transformers for exceptional signal handling without saturation and with extremely low phase distortion in the critical bass and mid regions. The result is exceptional clarity and definition at an attractive price point. Ultra-compact and made of 14 gauge steel, both ProDI models feature…
