Radial HDI Studio Grade DI
R800 2025 00
Radial HDI High Definition Studio Direct Box
The HDI is a studio-quality direct box designed to create exceptional recordings with any instrument, utilizing premium Jensen transformers and a unique Color control that provides an entirely new yet familiar-sounding sonic palette to experiment with.
  • Dial in an amazing tone within seconds
  • Blend from ultra-clean to amp-like distortion
  • Smooth Opto compressor for peak reduction
  • Mic and line-level outputs
  • Oversized custom-wound Jensen transformer
Instant Gratification
Despite the complex circuitry housed within the unit, the HDI has an elegant set of controls that allows the musician or engineer to dial up a record-ready sound with a minimal amount of tweaking required. The Level control drives the inputs of the HDI with instant visual feedback from the responsive front panel meter, while the Color knob provides seamless blending between an ultra-clean tone and amp-style distortion and saturation, so you can add just the right amount of character and grit to your instrument. A smooth Opto compressor can be engaged to control the peaks of the input signal, and a High-Pass Filter clears up any excessive low frequencies added by the Color control. Lastly, a Presence control accentuates the highs and high-mids, providing the ability to cut through the mix with results that are sure to impress.
Looks and Personality
With its gunmetal anodized 1/4" thick milled front panel and distinctive styling reminiscent of classic outboard studio equipment, the HDI is sure to turn heads in any recording space. A custom output meter provides a level check at a glance, with oversized chrome knobs for precise adjustments and easy tweaking on-the-fly. The HDI is a stunning standalone unit, but it also comes complete with mounting hardware to install in standard 19" equipment racks. One or two HDI's can be installed side-by-side in a 2RU rack space, and like all Radial products, they are built with rugged components and designed to easily withstand the rigors of concert touring.
Behind the Design
While the HDI is incredibly easy to use - requiring only a few seconds to achieve great-sounding results - both the design philosophy and the under-the-hood processes at work are anything but simple. Click here to read an interview with the HDI's designer, W.C. "Hutch" Hutchison for an in-depth look at how the HDI came to be and what makes its circuitry so unique.

Radial PZ-DI Orchestral Acoustic DI-Box
R800 3005 00
Radial PZ-DI Orchestral Instrument DI - Variable Load Active DI with Piezo Optimized Input
The PZ-DI™ is an active direct box that has been designed for acoustic and orchestral instruments, with a variable load that allows you to set the optimal input impedance for your pickups for more natural-sounding results.
  • Optimized for orchestral instruments on a live stage
  • Adjustable load for piezo and magnetic pickups
  • Variable low-cut filter to control low frequency resonance
  • Powered by 48V phantom, no batteries required
Piezo problem solver
The PZ-DI has a variable load selector switch that allows you to set the input impedance of the direct box, so you can optimize the performance with your instrument's pickups. The 1 meg ohm position delivers the classic impedance found on most active DI boxes, while the 220k ohm setting warms up the tone of magnetic pickups to provide the feel and tone as if your instrument were connected directly to an amplifier. The third setting is an ultra-high 10 meg ohm impedance that is specifically designed for piezo transducers, helping compensate for the harsh or squawky tone that can occur when a piezo is connected to a lower impedance input.
Variable filter to suit any instrument
To remove unwanted resonance on stage and prevent feedback, the PZ-DI is equipped with a fully-variable low-cut filter that gently rolls off low frequencies. The roll-off point of this filter can be raised or lowered to match the frequency response of your instrument, with a lower point for acoustic bass and a higher setting for violin or banjo. A switchable high-cut filter is also included, which is useful on instruments such as acoustic guitars that incorporate a battery-powered preamp, softening any harshness or high frequency edge for a smoother tone.

Radial StageBug SB-4 Active DI, piezo
R800 0140 00
Radial StageBug SB-4 Compact Active DI with Piezo Input
The StageBug SB-4 is a compact active direct box that has been optimized for use with piezo transducers, allowing upright basses, violins, cellos, and other acoustic instruments to be connected to the PA without compromising their tone or frequency response
  • Active DI optimized for piezo transducers
  • Smooths out peaks & eliminates squawk
  • Powered by 48V phantom, no batteries required
  • Compact design fits in your instrument case
The perfect companion for piezo instruments
The StageBug SB-4 allows you to retain the natural tone of your piezo-equipped instrument when amplified through a PA system. Unlike typical direct boxes, the SB-4 features a very high 5 meg ohm impedance that smooths out troublesome peaks that give piezo transducers a bad name. This higher impedance also broadens the frequency response for a more natural and pleasing sound. The active circuit balances the audio signal to enable long runs up to 100 meters without loss, while delivering spectacular linearity and low distortion throughout the audio range. Output connections include an aux out for a stage amplifier plus a standard XLR output to feed the PA.
Control feedback on stage
To help eliminate feedback on a live stage, the SB-4 is equipped with a high-pass filter and 180° polarity reverse switch. The high pass filter eliminates excessive bottom end which in turn reduces resonance that can cause the instrument to vibrate. The 180° polarity reverse helps reduce acoustic hot spots on stage by changing the phase relationship between the PA system and room acoustics which can combine at certain frequencies to create peaks.

Radial JDX 48 Phantom
R800 1402 00
Radial JDX Guitar Amp Direct Box
The JDX 48™ is a direct box designed to capture the sound of an electric guitar amplifier by connecting between the amp head and the speaker cabinet, providing a balanced feed for the PA system that sounds like a well-placed microphone on your amp.
  • Capture the sound of your amplifier through a direct box
  • Delivers consistent tone across every performance
  • Works equally well on electric guitar and bass
  • Can be powered from 48V phantom or DC supply
Deliver your amp's tone through the PA
The JDX 48 makes it easy to get a consistent and natural amplifier tone through the PA system night after night, by taking a feed directly from your amplifier and employing Radial's popular JDX speaker emulation that produces an effect similar to placing a dynamic microphone in front of a 4x12 half stack cabinet. This gives you a more manageable sound onstage for gigs where feedback is an issue, or if mic'ing your amp isn't an option. For artists that employ in-ear monitoring systems, the JDX 48 provides consistent tone each night in the monitor mix for shorter setup times and a more comfortable audio feed for the artist.
Dual powering options
The JDX 48 can be powered using 48V phantom from the mixing console, for a cleaner setup on stage that eliminates the need to carry a power supply to the gig. However, for times when phantom power may not be available, the JDX 48 also ships with a separate DC power supply - giving you a redundant powering option so you never have to perform without your JDX.

Radial 4 -Play Multi Output DI Box
R800 1432 00
Radial 4-Play Multi-Output DI - Active DI Box with Four Selectable Outputs
The 4-Play is a DI box specifically designed for multi-instrumentalists, providing the ability to quickly and silently change instruments on stage. With four balanced outputs, each instrument has its own channel in the PA and monitors.
  • Quick changeovers for multi-instrumentalists
  • Switch between four DI outputs using a single footswitch
  • Shared tuner output & mute footswitch
  • Ground lift switches to eliminate hum and buzz
Four DI boxes in one
Many performing multi-instrumentalists will have each of their instruments feed a separate channel in the PA system, allowing for individual level, EQ, and effects settings. Typically this would require multiple DI boxes and instrument cables, creating a mess on stage that can be difficult to manage. With the 4-Play, you only need to connect one cable to the input of the pedal, and it provides you with four DI outputs to feed the PA system. Not only does this mean fewer cables on stage and less devices to keep track of, but it also eliminates the need to flag down the sound engineer when you need to switch instruments during a performance. The 4-Play puts you in control, while streamlining your setup on stage.
