Introducing the R-DB20 Microphone In-Line Signal Booster
The Royer R-DB20 is a premium phantom-powered device designed to enhance the performance of ribbon and dynamic microphones. Serving as both a signal booster and impedance buffer, this versatile accessory ensures minimum distortion and coloration while increasing the level of low-output microphones.
Ideal for professional applications, the R-DB20 offers two selectable clean gain boost levels: 12dB and 20dB. Easily switchable via the convenient front panel switch, this innovative feature allows users to achieve the perfect balance between gain and headroom for various purposes.
Thanks to its Class A input circuitry, the R-DB20 maintains a high source impedance, effectively minimizing loading and improving overall sound quality. This reduction in coloration and distortion guarantees exceptional clarity and accuracy.
By utilizing the R-DB20's 12/20dB gain switch, you can achieve optimal balance between gain and headroom, catering to the specific requirements of your recording setup.
Moreover, the low-impedance output of the R-DB20 ensures an increased microphone-level signal, making it capable of directly driving a digital interface or a standard microphone preamplifier. Additionally, this feature minimizes signal loss, making it ideal for long cable runs.
Experience enhanced microphone performance with the R-DB20 Microphone In-Line Signal Booster, delivering impeccable sound quality for professional applications.
