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 like a subtle limiter which is particularly advantageous when interfacing the ProD2 with digital pianos, samplers and drum machines that can produce excessive dynamics.

This connects to the custom made Eclipse ET-DB3 transformer which performs the impedance matching and balances the signal. When using extra high output instruments, a -15dB pad can be inserted into the signal path. This enables the SB-2 to be used with active basses and digital pianos that often tend to overload the input side of the interface. An innovative stereo-to-mono merge function provides a convenient way to connect stereo keyboards and computers without having to reset the source for mono operation, saving time and input channels on the PA. The SB-2 output features an XLR wired to the AES standard with pin-2 hot. Once connected, the SB-2 delivers a smooth warm sound reminiscent of older vintage gear. The Eclipse ET-DB3 transformer is magical in its ability to handle extreme signal levels with a natural compression that is pleasing to the ears. The transformer also helps eliminate hum and buzz caused by ground loops by isolating the input from the output. This is augmented with a ground lift switch that lifts pin-1 on the XLR for quiet, professional results.\u003c\/p\u003e\n\u003ctable class=\"table feature-product\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecifications\u003c\/th\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio circuit type:\u003c\/td\u003e\n\u003ctd\u003ePassive, transformer based\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransformer:\u003c\/td\u003e\n\u003ctd\u003eEclipse ET-DB3, 12:1 ratio\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of channels:\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response:\u003c\/td\u003e\n\u003ctd\u003e20Hz ~ 20KHz (± 0.5dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDynamic range:\u003c\/td\u003e\n\u003ctd\u003e115dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal harmonic distortion:\u003c\/td\u003e\n\u003ctd\u003e0.005% @ 1kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Deviation:\u003c\/td\u003e\n\u003ctd\u003e3° @ 100Hz; 8° @ 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance:\u003c\/td\u003e\n\u003ctd\u003e140k Ohms, unbalanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Impedance:\u003c\/td\u003e\n\u003ctd\u003e1k Ohms, balanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Input:\u003c\/td\u003e\n\u003ctd\u003e+20dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"heading\"\u003e\n\u003ctd colspan=\"2\"\u003eFeatures\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003eInput pad, Ground lift\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Connectors:\u003c\/td\u003e\n\u003ctd\u003e1\/4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Connectors:\u003c\/td\u003e\n\u003ctd\u003eXLR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"heading\"\u003e\n\u003ctd colspan=\"3\"\u003eGeneral\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction:\u003c\/td\u003e\n\u003ctd\u003e14 gauge steel chassis \u0026amp; outer shell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize (L x W x D):\u003c\/td\u003e\n\u003ctd\u003e4.5\" x 1,85\" x 1.35\" (114mm x 47mm x 34mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight:\u003c\/td\u003e\n\u003ctd\u003e0.55 lbs (250 grams)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping size (L x W x D):\u003c\/td\u003e\n\u003ctd\u003e8\" x 5\" x 3\" (203mm x 127mm x 76mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping weight:\u003c\/td\u003e\n\u003ctd\u003e0.8 lbs (365 grams)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower:\u003c\/td\u003e\n\u003ctd\u003ePassive, no power required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConditions:\u003c\/td\u003e\n\u003ctd\u003eFor use in dry locations only between 5°C and 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty:\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\u003ca href=\"https:\/\/www.radialeng.com\/product\/stagebug-sb2\/legal.php#Warranty\"\u003eRadial 3-year, transferable\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2021\/09\/SB-2-QuickStart-WEB-09-2021.pdf\" target=\"_blank\" title=\"Radial StageBug SB-2 User Guide\" rel=\"noopener\"\u003eUser Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Radial","offers":[{"title":"Default Title","offer_id":47951972892890,"sku":"R800 0120","price":94.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0014\/9585\/9277\/files\/sb2-34-left.jpg?v=1780539121"},{"product_id":"radial-j48-mono-active-direct-box","title":"Radial J48 Mono Active Direct Box","description":"\u003ch2 class=\"intro-h2\"\u003ePhantom Powered Active Direct Box\u003c\/h2\u003e\n\u003cdiv class=\"intro-p\"\u003e\n\u003cp\u003eThe J48 is a high performance active direct box for live concert touring and professional recording studio applications, with the ability to handle extreme transients without distortion while delivering the natural sound of your instrument.\u003c\/p\u003e\n\u003ch2\u003eHigher Rail Voltage, Higher Headroom\u003c\/h2\u003e\n\u003cp\u003eMost 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 that are only able to handle about 3 Volts.

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.\u003c\/p\u003e\n\u003ctable class=\"table feature-product\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecifications\u003c\/th\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio circuit type:\u003c\/td\u003e\n\u003ctd\u003eProprietary analog circuit with low-noise op-amp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of channels:\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response:\u003c\/td\u003e\n\u003ctd\u003e20Hz ~ 20kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDynamic range:\u003c\/td\u003e\n\u003ctd\u003e109dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal harmonic distortion:\u003c\/td\u003e\n\u003ctd\u003e0.002% @ -5dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIntermodulation Distortion:\u003c\/td\u003e\n\u003ctd\u003e0.003% @ -3dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Deviation:\u003c\/td\u003e\n\u003ctd\u003e+10º at 20Hz | 0º at 1kHz | -1º at 20kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance:\u003c\/td\u003e\n\u003ctd\u003e220kΩ - ¼\" input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Impedance:\u003c\/td\u003e\n\u003ctd\u003e600Ω - XLR output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEquivalent Input Noise:\u003c\/td\u003e\n\u003ctd\u003e-103dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise Floor:\u003c\/td\u003e\n\u003ctd\u003e-99dB below 0dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Input:\u003c\/td\u003e\n\u003ctd\u003e+10dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"heading\"\u003e\n\u003ctd colspan=\"2\"\u003eFeatures\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003eInput pad, 180° polarity reverse, Ground lift, HPF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Connectors:\u003c\/td\u003e\n\u003ctd\u003e2x 1\/4\" in and thru\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Connectors:\u003c\/td\u003e\n\u003ctd\u003e2x XLR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"heading\"\u003e\n\u003ctd colspan=\"3\"\u003eGeneral\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction:\u003c\/td\u003e\n\u003ctd\u003e14 gauge steel chassis and outer shell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize (L x W x D):\u003c\/td\u003e\n\u003ctd\u003e3.3\" x 5.0\" x 2\" (84 x 127 x 48mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight:\u003c\/td\u003e\n\u003ctd\u003e1.55 lb (720 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower:\u003c\/td\u003e\n\u003ctd\u003e48V phantom - proprietary digital switching\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConditions:\u003c\/td\u003e\n\u003ctd\u003eFor use in dry locations only between 5°C and 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty:\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\u003ca href=\"https:\/\/www.radialeng.com\/product\/j48-stereo\/legal.php#Warranty\"\u003eRadial 3-year, transferable\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2026\/04\/J48-Stereo-Manual-WEB-04_2026.pdf\" target=\"_blank\" title=\"Radial J48 Stereo User Guide\" rel=\"noopener\"\u003eUser Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Radial","offers":[{"title":"Default Title","offer_id":47956228440282,"sku":"R800 3002","price":399.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0014\/9585\/9277\/files\/J48-Stereo-34.jpg?v=1780681225"}],"url":"https:\/\/www.rocketmusicshop.com\/collections\/direct-boxes.oembed","provider":"RocketMusic","version":"1.0","type":"link"}
