It features the same award-winning signal path that made the single-channel J48 the most recommended active DI box for touring.\u003cbr\u003eThe design begins with 14-gauge steel construction 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.\u003cbr\u003eInside, an exclusive power supply converts 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 easily handle high-output instruments. In addition, a -15dB pad can be activated for managing extreme signals. There is also a high-pass filter that gently attenuates low frequencies below 80Hz to clean up muddy sounds and excessive resonance. The 180º polarity reverse will help when using double-coil pickups to align the phases of sources or eliminate acoustic hot-spots that can cause feedback on stage.\u003cbr\u003eA unique aspect of the power supply is how the RADIAL ENGINEERING J48 STEREO 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 this turns off the 48-volt phantom power from the console, forcing you to introduce a battery into the system. Unfortunately, batteries are inconsistent, and as they begin to discharge, they severely affect the available voltage and resulting headroom. Instead, the RADIAL ENGINEERING J48 STEREO employs a DC-DC converter with a high-frequency transformer that allows the audio ground to be isolated from the power supply. This does not turn off the phantom power and is invisible to the user.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eVery low distortion\u003c\/li\u003e\n\n\u003cli\u003eExceptional headroom \u0026amp; dynamic range\u003c\/li\u003e\n\n\u003cli\u003eMaintains the instrument's natural sound\u003c\/li\u003e\n\n\u003cli\u003ePowered by 48V Phantom power\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"RADIAL","offers":[{"title":"Default Title","offer_id":53994049339725,"sku":"GRAD8001121","price":399.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/126499-large_default.jpg?v=1779950027","url":"https:\/\/musicdelivery.net\/en\/products\/radial-engineering-j48-stereo-di-box-stereo-attiva","provider":"Music Delivery","version":"1.0","type":"link"}
