Designed to handle extreme signal levels without distortion, it utilizes two world-class Jensen JT-DB-EPC audio transformers to deliver a smooth, warm sounding Bessel curve - reminiscent of the finest vintage gear. Ruler flat from 10Hz to 40kHz and with virtually zero phase deviation, the JDI Duplex delivers the natural, pure sound of the instrument without artifact. The inputs can be accessed via 1\/4\", RCA, 3.5mm TRS, or XLR line-level connectors, making it easy to plug in any sound source, from stereo instruments to consumer playback equipment, or professional +4dB line-level audio equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDuplex in Multimedia System\u003c\/strong\u003eWhether you have a CD player, iPod, computer or professional +4dB balanced source, the Duplex can handle any situation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDuplex with Stereo Keyboard\u003c\/strong\u003eThe Duplex is able to withstand huge transients without distortion.

It features two custom-made nickel laminated transformers for optimal signal transfer with absolute minimal distortion of all types. Analysis reveals an exceptionally linear response from 10Hz to 40kHz with virtually zero phase shift at all critical frequencies. The excellent performance is further substantiated with a Fast Fourier transform that produces desirable even order harmonic generation and a warm Bessel curve when pushed hard. With its heavy-duty steel shell and internal I-beam construction, the Duplex is designed to work dependably for years in the harshest of touring environments. A full complement of connectors make the Duplex a God-send when faced with the never-ending challenges of professional touring, broadcast and AV integration.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eJensen transformer equipped passive DI\u003c\/li\u003e\n\u003cli\u003eEliminates hum and buzz from ground loops\u003c\/li\u003e\n\u003cli\u003e1\/4?, 3.5mm, RCA, and XLR inputs to connect to any source\u003c\/li\u003e\n\u003cli\u003eExceptional signal handling and noise rejection\u003c\/li\u003e\n\u003cli\u003eTurns the input \u0026amp; thru jacks into a passive mixer to sum stereo signals to mono.\u003c\/li\u003e\n\u003cli\u003eReduces the input sensitivity to allow high output signals from keyboards to be connected without distortion.\u003c\/li\u003e\n\u003cli\u003eMini TRS provides easy interface for laptops, tablets, smart phones and iPods.\u003c\/li\u003e\n\u003cli\u003eStereo inputs for -10dB consumer level devices such as CD players and other hifi devices.\u003c\/li\u003e\n\u003cli\u003eReverses pin-2 and pin-3 on the XLR output to help phase align the stage sound with the PA system.\u003c\/li\u003e\n\u003cli\u003eLifts the audio ground (pin-1 on the XLR output) to help reduce hum and buzz caused by ground loops;\u003c\/li\u003e\n\u003cli\u003eActivates the +4dB line level balanced XLR input and disconnects the ¼\" \u0026amp; RCA jacks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAudio circuit type: Passive, transformer based\u003c\/li\u003e\n\u003cli\u003eTransformer: Jensen JT-DBE\u003c\/li\u003e\n\u003cli\u003eNumber of channels: 2\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20Hz ~ 20kHz at +\/- 0.2dB\u003c\/li\u003e\n\u003cli\u003eDynamic range: 135dB\u003c\/li\u003e\n\u003cli\u003eTotal harmonic distortion: 0.001%; 1kHz\/+4dBu; 600 Ohm load\u003c\/li\u003e\n\u003cli\u003ePhase Deviation: -1° @ 20Hz; 0.5° @ 150Hz; 600 Ohm load\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 140k Ohm Pad off; 10k Ohm Pad on\u003c\/li\u003e\n\u003cli\u003eOutput Impedance: 600 Ohms\u003c\/li\u003e\n\u003cli\u003eMaximum Input: +20dB @ 1kHz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInput pad, Mono Sum, 180° polarity reverse, Ground lift\u003c\/li\u003e\n\u003cli\u003eInput Connectors: 1\/4\", RCA, 3.5mm, XLR\u003c\/li\u003e\n\u003cli\u003eOutput Connectors: XLR, 1\/4\" thru\u003c\/li\u003e\n\u003cli\u003eExtras: Line Level or hi-Z input\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eGeneral\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConstruction: 14 gauge steel chassis \u0026amp; outer shell\u003c\/li\u003e\n\u003cli\u003eSize (L x W x D): 160mm x 48 x 127mm (6.3\" x 1.9\" x 5\")\u003c\/li\u003e\n\u003cli\u003eWeight: 1kg (2.2lbs)\u003c\/li\u003e\n\u003cli\u003eShipping size (L x W x D): 210 x 159 x 83mm (8.25\" x 6.25\" x 3.25\")\u003c\/li\u003e\n\u003cli\u003eShipping weight: 1.43 kg (3.15 lbs)\u003c\/li\u003e\n\u003cli\u003ePower: Passive, no power required\u003c\/li\u003e\n\u003cli\u003eConditions: For use in dry locations only between 5°C and 40°C\u003c\/li\u003e\n\u003cli\u003eWarranty: Radial 3-year, transferable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ciframe width=\"815\" height=\"458\" src=\"https:\/\/www.youtube.com\/embed\/Mhc2RyaEczM\" title=\"Tech Corner - A Good Day to D.I.\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"Radial Engineering","offers":[{"title":"Default Title","offer_id":50886667862191,"sku":"DUPLEX","price":213.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/5078\/7759\/files\/DUPLEX.jpg?v=1794614681","url":"https:\/\/voltrivooo.myshopify.com\/products\/radial-jdi-duplex-di-new","provider":"VOLTRIVOO","version":"1.0","type":"link"}
