It increases the level of passive low-output ribbon and dynamic microphones with a minimum of distortion or coloration. Designed for professional applications, the dBooster provides two levels of clean gain boost; 12 dB and 20 dB, selectable by a front panel switch. The dBooster maintains headroom and gain regardless of load. The Class A input circuitry presents a high source impedance to the microphone, which minimizes loading (damping). This reduces coloration and distortion while at the same time improving headroom. By utilizing the 12\/20 dB gain switch, optimum balance between gain and headroom can be achieved for a variety of uses. The low-impedance output of the dBooster is an increased microphone-level signal that can drive a digital interface directly or a standard microphone preamplifier. It also minimizes signal loss on long cable runs.\u003c\/p\u003e\r\n\r\n\u003ch3\u003eRECOMMENDED APPLICATIONS:\u003c\/h3\u003e\r\n\r\n\u003cul\u003e\r\n\u003cli\u003eMiking any low-volume sound source (acoustic instruments, vocals, etc.)\u003c\/li\u003e\r\n\u003cli\u003eRecording direct to a DAW interface\u003c\/li\u003e\r\n\u003cli\u003eUse on long cable runs to retain sound quality\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\r\n\r\n\r\n\r\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\r\n\r\n\u003cul\u003e\r\n\u003cli\u003eGain: 12 dB or 20 dB switchable\u003c\/li\u003e\r\n\u003cli\u003eTHD+N: @ 20 dB Gain = .0015%, -25 dBu input signal,\u003c\/li\u003e\r\n\u003cli\u003e1.3Vp-p output signal; @ 12 dB Gain = .001%, -6Bu input signal,\u003c\/li\u003e\r\n\u003cli\u003e3.66Vp-p output signal\u003c\/li\u003e\r\n\u003cli\u003eIM Distortion: @ 20 dB setting, \u0026lt;.002% @ 800 mV output,; @ 12 dB setting, \u0026lt;.005% @ 2.6 volts output\u003c\/li\u003e\r\n\u003cli\u003eSelf-noise: referred to -48 dB re 1V\/pa, 20 dB setting \u0026lt;11 dBa, 12 dB setting \u0026lt;15 dBa\u003c\/li\u003e\r\n\u003cli\u003eHeadroom: referred to -48dB re 1V\/pa and 4mV\/pa, 20 dB setting: 127 dB, 12 dB setting: 120 dB\u003c\/li\u003e\r\n\u003cli\u003eFrequency response: 20 Hz - 20 kHz ±0.25 dB\u003c\/li\u003e\r\n\u003cli\u003eInput Impedance: 3.6K-Ohm\u003c\/li\u003e\r\n\u003cli\u003eOutput Impedance: (at 20 dB setting) 300 Ohms\u003c\/li\u003e\r\n\u003cli\u003eCurrent draw: approximately 5 mA at zero signal and 7.5 mA at full output\u003c\/li\u003e\r\n\u003cli\u003eInput and output connections: Balanced XLR: (Pin 1 Ground, Pin 2 Signal Hot, Pin 3 Signal Cold)\u003c\/li\u003e\r\n\u003cli\u003ePower: 48-Volt phantom\u003c\/li\u003e\r\n\u003cli\u003eDimensions: 3.62” (92 mm) L X 2.0” (51 mm) W X 1.62” (41.3 mm) W\u003c\/li\u003e\r\n\u003cli\u003eWeight: 6 oz (170 g)\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Royer Labs","offers":[{"title":"Default Title","offer_id":44450376056935,"sku":"113624","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/royer-labs-dbooster-23_113624_1_f594ecdb-6030-4a4e-8d25-ec74e015f0c1.jpg?v=1787092806","url":"https:\/\/vintageking.com\/products\/royer-r-db20-dbooster","provider":"Vintage King","version":"1.0","type":"link"}
