Active DI

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.

Most battery-powered guitars and basses will produce as much as 7 Volts when played at maximum volume, which can easily overload typical active direct boxes which have are only able to handle about 3 Volts. The J48 uses a unique switching power supply that raises the internal rail voltage so it can handle up to an incredible 9 Volts, resulting in improved signal handling and greater headroom. This additional headroom significantly reduces distortion of all types, allowing the natural tone and character of the instrument to shine through.

Most battery-powered instruments and stereo keyboards will produce as much as 7 Volts when played at maximum volume, which can easily overload typical active direct boxes which have are only able to handle about 3 Volts. The J48 Stereo uses a unique switching power supply that raises the internal rail voltage so it can handle up to an incredible 9 Volts, resulting in improved signal handling and greater headroom. This additional headroom significantly reduces distortion of all types, allowing the natural tone and character of the instrument to shine through. The J48 maintains stereo separation between the left and right channels, allowing it to be used on two separate instruments or with stereo sources such as keyboards.

The Pro48's innovative internal switching power supply significantly increases headroom producing less distortion while yielding a smooth, linear response that extends from 20Hz to well above 40kHz. This results in natural, uncolored signal that is as good or better than DI boxes costing several times more. The superior performance makes the Pro48 an ideal candidate for use with battery powered active basses and acoustic guitars that tend to overload other direct boxes.

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.

Whether you are playing backing tracks on stage, giving an audio presentation, or performing the role of DJ at an event, the USB-Pro is the easiest way to provide a high quality noise-free connection between a laptop and any sound system. Made for plug and play simplicity, the USB-Pro will automatically be listed as an available sound card in the audio settings of all popular operating systems including Windows and Mac, with 24bit/96kHz digital to analog converters that retain the quality of the audio signal. A stereo pair of balanced XLR outputs allows you to connect to a microphone preamplifier, PA system, mixing console, or even a powered speaker, with an on-board level control for quick and easy volume adjustments. Should any noise be encountered, ground lift switches are provided and isolation transformers can be inserted into the signal path to eliminate hum and buzz from ground loops, for a clean connection to the PA.

The BT-Pro makes it easy to quickly connect to any smartphone, tablet, or mobile device for high quality audio playback through a sound system. It wirelessly pairs over Bluetooth, eliminating the need to search for adaptor cables and providing you with the freedom to move around while staying connected.

A level control allows for easy volume adjustments, along with a headphone output for testing and troubleshooting.

The JPC is a stereo direct box that is easy to use with practically any consumer electronic device. It utilizes active buffers and transformer isolation to create a hybrid circuit that blocks ground loops and reduces system noise, along with AC blocking capacitors to prevent any audio system noise from bleeding back into the computer. The choice of ¼", RCA and 3.5mm input connectors make it easy to interface with all types of unbalanced audio sources such as computers, smartphones, and tablets, and the outputs are XLR balanced mic level to feed snake systems and PAs. Powering the JPC is accomplished via 48V phantom from a mixing console, allowing the JPC to be used in concert environments without requiring an external power supply.

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.

The design begins with standard ¼ instrument input with a thru-put to feed your tuner or your on-stage amp. The ultra-quiet active circuit at once converts the signal from high to low impedance to reduce susceptibility to noise. The signal is then buffered and balanced for long cable runs to the PA system. 48 volt phantom provides the power, so the SB-1 does not require batteries or external supply to make it work. You simply plug in and you are ready to go!

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.

The Firefly's drive circuit utilizes a 12AX7 vacuum tube, which is the most popular tube made today and can be found in nearly all guitar amplifier designs. This helps provide the character and feel of a vintage device, while still maintaining low distortion and noise profiles common to modern pro audio equipment. The Firefly excels when used on instruments that sound too clinical or one dimensional when recorded directly, adding punch and warmth to bass or guitar tracks both on stage and in the recording studio.

The JDV makes no compromises on available features or audio quality, opting instead to provide anything you could ever ask of a high-performance DI box. Designed for studio recording or pro-touring applications, the JDV provides exceptional headroom with massive 30-Volt internal rails, resulting in virtually zero distortion and producing an incredibly transparent and natural representation of your instrument. It has two inputs which can be individually selected or blended together and phase-aligned, with the ability to handle condenser mic's, piezo transducers, and the outputs of effectively any instrument. The balanced output can be set to mic or line-level, allowing you to bypass an additional preamp and connect directly to a recording interface for pristine studio recordings.

The J33 provides the ability to connect turntables to pro audio equipment such as a recording interfaces and mixers, allowing you to easily integrate your vinyl collection with studio gear for playback or recording. Balanced XLR mic-level outputs are available for connection to a mic preamplifier for archiving or sampling in the studio, and -10dB consumer line-level outputs are also provided to connect to home stereo equipment. The J33 can also be used in a live performance environment, offering an improved interface for DJs to connect to the PA system.

Featuring two built-in JDX amp DIs—one pre-EQ and one post-EQ—the Headload eliminates the need to use a microphone to capture the sound from your amplifier. Should you decide to combine the DI signal with a microphone, the Headload is augmented with a built-in Radial Phazer to time-align the two signals to create massive tones. The Headload uses a 6-position rotary switch to set the desired power reduction from unaltered all the way down to complete silence. When the output is completely soaked, the high-quality headphone amplifier can be used for silent 3:00AM practicing

With the Headload Prodigy, you can crank your amp to the sweet spot while keeping output levels in check, allowing you to retain your optimal tone when performing, recording and practicing. The Prodigy can pass 25%, 50% or 100% of the signal from the amp head to the speaker cabinet, or it can also be used without a speaker cabinet for completely silent recording. This is particularly useful in small venues where the speaker cabinet on stage may conflict with the sound in the room, and it's also great for silent recording where you want to take advantage of 'high power' amp distortion without upsetting the neighbours. A balanced DI output features Radial's popular JDX Reactor circuit, which emulates the tone of a 4x12 half stack for a realistic and consistent tone through the PA or when connected to a recording interface.

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.

The DAN-RX provides a simple way to take a stereo feed from a Dante network and convert it to analog audio for monitoring in any location. Balanced XLR outputs allow you to connect to professional audio equipment such as a mixing console, amplifier, or a pair of powered speakers. In addition, a local 3.5mm headphone output is equipped with its own level control to test audio before connection to the PA system or to monitor locally with headphones, making it useful in events that use personal monitor systems. The DAN-RX can be powered from an included external supply or any Power over Ethernet (PoE) network switch, and both of these options can be used simultaneously to provide redundancy for critical applications.
