Linear from 10Hz to 40kHz and with virtually zero phase deviation, the JDI Stereo keeps the instrument's sound natural and pure, not artificial. In addition to converting the unbalanced Hi-Z signal, the transformers isolate the input from the output, filtering out DC voltage that can cause noise and lead to so-called ground loops. All of this allows audio to pass through while eliminating problems.\u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"The internal Jensen transformers, renowned for their ability to correctly handle transients with a soft and warm Bessel curve, reminiscent of the best vintage devices.\" src=\"\/images\/uploads\/\/JDI-1200x630_02.jpg\" title=\"The internal Jensen transformers, renowned for their ability to correctly handle transients with a soft and warm Bessel curve, reminiscent of the best vintage devices.\"\u003e\u003c\/p\u003e\u003cp\u003eFeatures include ¼\" input and thru-put connectors plus a -15dB input pad on each channel. There is also a ground lift switch that lifts pin 1 on the two XLR outputs to further reduce hum and noise caused by ground loops. Built robustly to withstand the extreme demands of touring, the JDI Stereo uses a 14-gauge I-beam steel frame and an exclusive book-style outer shell. The innovative design eliminates stress on the circuitry, reducing the possibility of solder joint detachment, while the outer shell creates a protective zone around switches and connectors. The steel enclosure works with the mu-metal transformer and internal Faraday shielding to protect sensitive internal mechanisms from powerful magnetic fields, such as those generated by amplifiers, ensuring quiet, hum-free signal handling. The original Radial JDI has become the most famous passive direct box in professional touring and recording studios worldwide, and there is no doubt that the JDI Stereo will follow suit. The combination of these features has made the Radial JDI the most famous passive direct box in professional touring and an excellent choice for studio instrument use!

Low distortion is ensured by a unique digital switching power supply that increases the internal operating voltage, adding headroom and improving signal handling. The J48 is ideal for both live and studio use, with a robust and durable metallic construction. It features a -15dB input pad to handle particularly strong signals, 180º polarity reversal for feedback control on stage, and a ground lift to reduce hum and noise caused by ground loops. Special features of the J48 include the Merge function, which combines left and right signals into a single mono signal without phase cancellation. To minimize feedback with acoustic instruments, the J48 has an 80Hz high-pass filter (low-cut) that can also increase headroom by eliminating unwanted low frequencies. The innovative and characteristic design of Radial products protects switches and connectors, while the internal I-beam architecture eliminates stress on the circuitry, protecting sensitive components from potential torsional damage and ensuring trouble-free performance for years.

It also balances the signal, allowing the use of cables up to 300 meters long without noise and without appreciable signal loss. Unlike classic Direct Boxes that simply use phantom power to manage an internal buffer, the J48 converts phantom power from DC to AC; subsequently, thanks to a unique switching power supply, it increases the internal operating voltage, ensuring greater headroom. In this way, the active amplifier (buffer) is not always at maximum: we do not have to trade frequency response for dynamic range. The result is a response curve that starts at 10Hz and extends well beyond 40kHz! This ensures that the natural timbre of the instrument is maintained without degradation or the introduction of artifacts.\u0026lt;\/p\u0026gt;\u0026lt;h3 style=\"text-align: justify;\"\u0026gt;\u0026lt;strong\u0026gt;Connections\u0026lt;\/strong\u0026gt;\u0026lt;\/h3\u0026gt;\u0026lt;p\u0026gt;As with any electronic audio device, make sure all levels are at zero and\/or power is off before making connections.

The J48 is designed to be used alone, with PA and monitoring systems, or in combination with the PA system and instrumental stage amplifiers. On large professional concert stages, monitors or stage sound are usually controlled by a monitor engineer or the front-of-house (FOH) engineer. In this case, the J48 is essentially invisible: the guitar connects to the J48 and the rest is managed like a microphone.

To eliminate feedback, the J48 is equipped with a Low-Cut (high-pass filter) that gradually reduces bass frequencies below 80Hz, eliminating low-frequency resonance. If you notice that feedback is more present in some areas of the stage and less in others, try using the polarity switch, which will change how the PA system and monitor wedges interact, improving the sound and eliminating resonant feedback hotspots. Some musicians prefer to have their own amplifier on stage to set the sound according to personal needs. However, this can be counterproductive in achieving good sound in the hall: for example, adding reverb on stage might seem good, but when playing in an arena with a lot of echo, more reverb means completely losing the acoustic guitar. The same applies to EQ: cutting the mid-range frequencies on stage might seem ideal, but the signal sent to the PA should be flat to allow the FOH engineer to mix the sound so that it stands above the drums and other instruments.\u0026lt;\/p\u0026gt;\u0026lt;h3 style=\"text-align: justify;\"\u0026gt;\u0026lt;strong\u0026gt;Using the J48 with a Bass\u0026lt;\/strong\u0026gt;\u0026lt;\/h3\u0026gt;\u0026lt;p style=\"text-align: justify;\"\u0026gt;As described earlier, just like an acoustic guitar, an electric bass can be used 'direct' or in conjunction with a bass amplifier. This applies to both studio recording and live performances. The advantage of a direct setup is simplicity. No amplifiers to carry around, no phase issues, just 'plug \u0026amp;amp; play'. The combination of direct feed from the Radial J48 with the sound of a mic'd amplifier is a more common approach, especially in a live event. With this setup, the bassist can create the sound and hear what they want on stage, which is extremely important for creating the right groove with the drummer. But even when it comes to EQ, what might sound good on stage doesn't necessarily sound good in the hall. This is why most musicians send the direct bass sound before it goes through the amplifier, allowing the FOH engineer to work with an unmodified sound and optimize the EQ for the room. Polarity inversion can sometimes help time-align low frequencies, reduce resonance, and make mixing easier.\u0026lt;\/p\u0026gt;\u0026lt;p style=\"text-align: justify;\"\u0026gt;\u0026lt;strong\u0026gt;\u0026lt;img alt=\" an electric bass can be used 'direct' or in conjunction with a bass amplifier.

When using the J48 with highly dynamic instruments like digital pianos, samplers, and drum machines, it is recommended to engage the -20dB pad in the circuit, reducing the possibility of overload distortion.\u0026lt;\/p\u0026gt;\u0026lt;h3\u0026gt;\u0026lt;strong\u0026gt;Merge Function\u0026lt;\/strong\u0026gt;\u0026lt;\/h3\u0026gt;\u0026lt;p\u0026gt;An interesting feature on the J48 is the Merge function, specifically designed to handle many left\/right keyboard outputs relative to the available channels on the mixer. By pressing the Merge switch, you can transform the input and throughput into two inputs, allowing you to passively mix the left and right signals into a mono output. This saves valuable setup time and eliminates the need to reprogram all sounds to mono.\u0026lt;\/p\u0026gt;\u0026lt;p style=\"text-align: center;\"\u0026gt;\u0026lt;img alt=\"By pressing the Merge switch, you can transform the input and throughput into two inputs, allowing you to passively mix the left and right signals into a mono output\" src=\"https:\/\/www.algameko.com\/images\/uploads\/J48.jpg\" title=\"By pressing the Merge switch, you can transform the input and throughput into two inputs, allowing you to passively mix the left and right signals into a mono output\"\u0026gt;\u0026lt;\/p\u0026gt;\u0026lt;h3\u0026gt;\u0026lt;strong\u0026gt;Using the J48 in the Studio\u0026lt;\/strong\u0026gt;\u0026lt;\/h3\u0026gt;\u0026lt;p style=\"text-align: justify;\"\u0026gt;Don't let the small size of the J48 compared to large and flashy studio Direct Boxes fool you. We've tested most of these expensive devices, and the J48 usually outperforms them when it comes to delivering fantastic audio. We're not saying that some of these studio DIs aren't useful; it can be fun to add personality to an instrument by introducing effects like tube distortion or radical EQ curves. The J48 was not designed to do this: its job is to send the most accurate signal possible to the recording system and allow the engineer to make artistic decisions from that point. With the advent of digital recording, 'extra tracks' open the door to creative options like never before. If you're recording bass or an acoustic or electric guitar, it's good practice to always record a track directly from the instrument. This way, you can capture a magical performance that cannot be recreated and insert it into the mix later. The Radial J48 is perfect for this. All you have to do is connect the instrument to the J48 and the Thru-put to the amplifier. The XLR output feeds your recorder, which you can safely use to capture tracks and save them for future use.\u0026lt;\/p\u0026gt;\u0026lt;p style=\"text-align: justify;\"\u0026gt;\u0026lt;img alt=\"\" src=\"https:\/\/www.algameko.com\/images\/uploads\/j48-app3.jpg\"\u0026gt;\u0026lt;\/p\u0026gt;\u0026lt;h3\u0026gt;\u0026lt;strong\u0026gt;Re-amping - Using Radial J48 and Radial X-Amp\u0026lt;\/strong\u0026gt;\u0026lt;\/h3\u0026gt;\u0026lt;p style=\"text-align: justify;\"\u0026gt;Re-amping, or re-recording, is a process that involves recording a clean track and then playing the clean track through a re-recording device like the Radial X-Amp using effect pedals and amplifiers. This technique, usually used with electric guitars, is now also employed with bass, keyboards, percussion, and even vocals! For applying the technique with guitar, first set up the guitar and amplifier as usual, except the guitar should be connected to the input of the Radial J48 and the Thru-put to the guitar amplifier as indicated. The XLR output of the J48 will feed the mixing console of the recording system. As soon as the guitarist starts playing, record their amplifier using a microphone and simultaneously capture the clean direct sound of the guitar through the J48. Once the track is recorded, you can send the guitarist home and get to work! Here's the point: after acquiring the recording, managing a messed-up note is easy if the signal is clean, but doing so with a distorted guitar track is difficult, if not impossible. Furthermore, having a guitarist play and play and play again before the microphones are set up around their amplifier can often take hours. A tired guitarist doesn't play like a fresh one! Capture the performance, then worry about the sound later. With the dry track recorded with the J48, you can now send the guitar signal to the Radial X-Amp. The X-Amp is fundamentally a line-level to guitar amplifier signal converter and distribution amplifier. It allows you to pre-record the balanced line signal to process it with guitar amplifiers or effect pedals. Press Play on the recorder, and then, through the X-Amp, send the signal back into the effects and various amplifiers. While you are playing back the track, a collaborator moves the microphone around the room until it sounds good.\u0026lt;\/p\u0026gt;This is the magic behind Re-amping.\u0026lt;\/p\u0026gt;\u0026lt;hr\u0026gt;\u0026lt;h2\u0026gt;\u0026lt;u\u0026gt;\u0026lt;strong\u0026gt;J48 Technical Specifications\u0026lt;\/strong\u0026gt;\u0026lt;\/u\u0026gt;\u0026lt;\/h2\u0026gt;\u0026lt;ul\u0026gt;    \u0026lt;li\u0026gt;Audio circuit type: Proprietary analog with Low-noise op-amp\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Frequency response: 20Hz ~ 20kHz\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Dynamic range: 109dB\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Total harmonic distortion: 0.002% @ -5dBu\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Intermodulation distortion: 0.003% @ -3dBu\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Phase deviation: +10º at 20Hz | 0º at 1kHz | -1º at 20kHz\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Input impedance: 220kΩ - ¼\" input\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Output impedance: 200Ω - XLR output\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Equivalent input noise: -103dBu\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Residual noise: -99dB below 0dBu\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Maximum input level: +10dBu\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Features\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Input pad, Mono Sum, 180° polarity inversion, Ground lift, HPF\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Input connectors: 1\/4\"\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Output connectors: Balanced XLR, 1\/4\" Thru\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;General specifications\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Construction: 14-gauge steel chassis and outer shell\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Dimensions (L x W x D): 84 x 127 x 48mm - 3.3\" x 5.0\" x 2\"\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Weight: 720 g - 1.55 lb\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Power supply: 48V phantom – Proprietary digital switching power supply\u0026lt;\/li\u0026gt;    \u0026lt;li\u0026gt;Conditions of use: Dry locations only between 5°C and 40°C\u0026lt;\/li\u0026gt;\u0026lt;\/ul\u0026gt;","brand":"RADIAL ENGINEERING","offers":[{"title":"Default Title","offer_id":58003743244633,"sku":"GRAD8001120","price":291.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1036\/3633\/6985\/files\/44-radial-engineering-j48-grad8001120_0.jpg?v=1778131402"},{"product_id":"j48-stereo-grad8001121","title":"Radial Engineering J48 STEREO","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u0026lt;h1 style=\"text-align: justify;\"\u0026gt;The Radial \u0026lt;strong\u0026gt;J48 Stereo\u0026lt;\/strong\u0026gt; is an \u0026lt;strong\u0026gt;active Direct Box\u0026lt;\/strong\u0026gt; with 2 inputs, offering high performance and extremely low distortion, high headroom and dynamic range, and a wide and linear frequency response.

It features the same signal path that made the single-channel J48 the most suitable active direct box for touring. And with users as diverse as Paul McCartney, Tommy Emmanuel, and Joe Chiccarelli, you can be sure it will meet the most demanding requirements. The design begins with a 14-gauge steel chassis and a robust book-end design that protects switches and connectors. The internal I-beam construction ensures that the circuit board does not twist, reducing the possibility of solder joint detachment and potential failures. All connectors are made of fiberglass-reinforced nylon and have large, oxidation-proof nickel-silver contacts.\u0026lt;\/p\u0026gt;\u0026lt;p style=\"text-align: justify;\"\u0026gt;\u0026lt;img alt=\"extremely linear frequency response from 10Hz to 40kHz and the ability to easily handle high-output instruments\" src=\"\/images\/uploads\/\/J48_Stereo_1200x630_02.jpg\" title=\"extremely linear frequency response from 10Hz to 40kHz and the ability to easily handle high-output instruments\" \/\u0026gt;\u0026lt;\/p\u0026gt;\u0026lt;p style=\"text-align: justify;\"\u0026gt;Inside, an exclusive power supply converts the 48-volt phantom power into AC current, increasing headroom, resulting in improved signal handling and reduced distortion. This translates into an extremely linear frequency response from 10Hz to 40kHz and the ability to effortlessly handle high-output instruments. Additionally, a -15dB pad can be activated for handling extreme signals. There is also a \u0026lt;strong\u0026gt;high-pass filter\u0026lt;\/strong\u0026gt; that gently attenuates low frequencies below 80Hz to clean up muddy sounds and excessive resonance. The 180º polarity reverse will help when using the J48 Stereo with dual-element pickups to align phase sources or eliminate acoustic hot-spots that can cause feedback on stage. A unique aspect of the power supply is how the J48 handles hum and buzz caused by ground loops. The traditional solution is to lift the audio ground by disconnecting pin 1 on the XLR output, but doing so turns off the 48-volt phantom power from the console, forcing a battery into the system. Unfortunately, batteries are inconsistent, and when they start to discharge, they severely affect the available voltage and the resulting headroom. Instead, the J48 employs a DC-DC converter with a high-frequency transformer that allows the audio ground to be eliminated from the power supply. This does not turn off the phantom power and is invisible to the user.\u0026lt;\/p\u0026gt;\u0026lt;hr \/\u0026gt;\u0026lt;h2\u0026gt;\u0026lt;strong\u0026gt;J48\u0026amp;trade; Stereo - Applications\u0026lt;\/strong\u0026gt;\u0026lt;\/h2\u0026gt;\u0026lt;h3\u0026gt;\u0026lt;strong\u0026gt;Using J48 Stereo with a keyboard\u0026lt;\/strong\u0026gt;\u0026lt;\/h3\u0026gt;\u0026lt;p\u0026gt;The J48's active circuit and amazing signal handling make it the ideal choice for \"old school\" analog and digital keyboards.

These provide a performance from 20 Hz to 20 kHz with a deviation of less than 1.5 dB above 18 kHz and are able to withstand very high signal levels without distortion. Unlike active circuits that overload when the signal exceeds the rail voltage, transformers saturate. This creates a pleasing effect that naturally rounds out the tone, acting as a subtle limiter, an effect particularly beneficial when connecting ProD2 with digital pianos, samplers, and drum machines that can produce excessive dynamics. Transformers are particularly effective in eliminating hum and noise caused by ground loops.\u003c\/p\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cimg alt=\"Digital instruments such as keyboards, synthesizers, and drum machines can benefit from the smooth and warm tone produced by ProD2's transformers.\" src=\"\/images\/uploads\/\/ProD2_1200x630_02.jpg\" title=\"Digital instruments such as keyboards, synthesizers, and drum machines can benefit from the smooth and warm tone produced by ProD2's transformers.\" \/\u003e\u003c\/p\u003e\u003ch2 style=\"text-align: justify;\"\u003e\u003cu\u003e\u003cstrong\u003eProD2 Applications\u003c\/strong\u003e\u003c\/u\u003e\u003c\/h2\u003e\u003ch3\u003e\u003cstrong\u003eProD2 with Stereo Keyboard\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003e\u003cimg alt=\"ProD2 is specially designed for stereo instruments such as keyboards and synthesizers.

Few realize that recording engineers not only reamp guitars, but often bass and keyboards, drums, and even vocals as a means to bring new creative sounds and sonic signatures to their music. Reamping has many advantages. You start by recording a clean track and focusing on capturing the best musical performance. Once the magic has been captured, you send the clean track back to the amplifiers and effects and adjust the sound to fit. No more hours of repetition for the guitarist, no rushed work due to scheduling, and best of all you don't have to compromise the sound of the track.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cp\u003e\u003cspan style=\"letter-spacing: 0.02em;\"\u003eMain Features\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003ePlays pre-recorded tracks through amplifiers and pedals\u003c\/p\u003e\u003cp\u003eLevel control for precise adjustments of amplification level\u003c\/p\u003e\u003cp\u003eTransformer isolated to eliminate buzz and hum\u003c\/p\u003e\u003cp\u003eOpens the door to new creative sounds and textures\u003c\/p\u003e\u003cp\u003eDimensions: 84 x 127 x 48 mm\u003c\/p\u003e\u003cp\u003eWeight: 720 g\u003c\/p\u003e","brand":"RADIAL ENGINEERING","offers":[{"title":"Default Title","offer_id":58010311917913,"sku":"RAD8001095","price":137.5,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1036\/3633\/6985\/files\/RAD8001095.jpg?v=1778198836"},{"product_id":"topp-pro-tdia2-di-box-attiva","title":"Topp Pro TDIA2 Active DI Box","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eTopp Pro TDIA2 Active DI Box\u003c\/p\u003e\u003cp\u003e1\/4\" unbalanced jack and XLR inputs\n\u003c\/p\u003e\u003cp\u003e1\/4\" unbalanced jack link output\n\u003c\/p\u003e\u003cp\u003eBalanced XLR output\n\u003c\/p\u003e\u003cp\u003eGround Lift switch\n\u003c\/p\u003e\u003cp\u003e20 dB attenuator\n\u003c\/p\u003e\u003cp\u003e48V phantom power or 9V battery\n\u003c\/p\u003e\u003cp\u003eDimensions: 130 x 127 x 45 mm\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cp\u003e1\/4\" unbalanced jack and XLR inputs\n\u003c\/p\u003e\u003cp\u003e1\/4\" unbalanced jack link output\n\u003c\/p\u003e\u003cp\u003eBalanced XLR output\n\u003c\/p\u003e\u003cp\u003eGround Lift switch\n\u003c\/p\u003e\u003cp\u003e20 dB attenuator\n\u003c\/p\u003e\u003cp\u003e48V phantom power or 9V battery\n\u003c\/p\u003e\u003cp\u003eDimensions: 130 x 127 x 45 mm\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e","brand":"TOPP PRO","offers":[{"title":"Default Title","offer_id":58044411806041,"sku":"713566","price":45.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1036\/3633\/6985\/files\/clipboard01_echw_bszn_o.jpg?v=1778583623"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1036\/3633\/6985\/collections\/reamp_frkn_lbpp_s.png?v=1778071558","url":"https:\/\/yourmusiconline.it\/en\/collections\/reamp-e-di.oembed","provider":"yourmusiconline.it","version":"1.0","type":"link"}
