Royer Labs R-DB20 dBooster The Royer Labs R-DB20 dBooster is a high-quality active inline microphone preamplifier designed to provide clean gain for passive microphones. It delivers low-noise amplification, allowing ribbon and dynamic microphones to reach their full performance potential. With its transparent gain stage, the dBooster enhances microphone performance in demanding recording situations without altering the natural tonal character. It also reduces the load on downstream preamps and helps maintain optimal gain structure throughout the signal chain. Sound Character The R-DB20 is extremely neutral and transparent. It boosts the signal without changing its tonal balance, preserving the original character of the microphone. Transients remain accurate, noise performance improves, and overall clarity is enhanced. The result is a cleaner, more stable, and professional input signal. Highlights ✔ active inline microphone preamp (signal booster) ✔ ideal for passive ribbon and dynamic microphones ✔ clean, low-noise gain (approx. +20 dB) ✔ transparent sound with no coloration ✔ improves gain structure and headroom of downstream preamps ✔ compact inline XLR design ✔ rugged metal construction ✔ easy integration into existing setups Typical Applications ✔ gain boost for passive ribbon microphones ✔ improving performance of dynamic microphones (especially on low-level sources) ✔ enhancing signal quality before audio interfaces ✔ recording with lower-gain preamps ✔ broadcast and podcast applications Technical Specifications ✔ type: active inline microphone preamplifier ✔ gain: approx. +20 dB ✔ power: phantom power required (48 V) ✔ connections: XLR (in/out) ✔ compatibility: passive microphones (not required for active mics) ✔ format: inline
