Royer dBooster2: Dual-Channel In-Line Gain Booster and DI

The Royer Labs dBooster2 is an advanced dual-channel in-line gain booster and DI (Direct Input) designed to provide versatile and high-quality gain for recording purposes. Building upon the features of the original dBooster, the dBooster2 introduces dual independent channels, each of which doubles as a high-quality DI for electric guitars and bass. This flexibility allows users to connect two microphones simultaneously, use both channels for DI applications, or mix and match a microphone with a DI input.

The Royer Labs dBooster2 is a versatile and advanced tool for audio professionals, providing dual-channel in-line gain boosting and high-quality DI capabilities for a wide range of recording applications.

Key Features

  • Dual Channels: Two independent channels, each capable of providing in-line gain for microphones or serving as a high-quality DI for electric guitars and bass.
  • Adjustable Gain Settings (Microphone Mode): Switch between 12 dB and 20 dB of gain depending on the recording needs.
  • Adjustable Gain Settings (DI Mode): Select 0 dB (unity) gain or switch to 8 dB of gain for electric guitars and bass in DI mode.
  • Dual Class A Input Stages: Delivers crystal clean gain with minimal noise and self-distortion through dual Class A input stages.
  • Low-Impedance Output: Maintains signal integrity in both studio and live settings, capable of driving long cable lengths and handling challenging loads.
  • Compatibility with Royer Microphones: Optimized for use with Royer R-121s, R-10s, and stereo SF-12s, also suitable for dynamic microphones like the SM7.
  • Built in the USA: Proudly built in the USA and shipped from Royer Labs’ headquarters in Burbank, California.
