The Royer Labs dBooster is a valuable tool for achieving clean and adjustable gain in various recording scenarios, providing audio professionals with a versatile solution for enhancing the quality and flexibility of their recordings.
Adjustable Gain Settings: The dBooster features two gain settings, 12 dB and 20 dB, allowing users to select the appropriate level of in-line gain for different recording situations. The 20 dB setting provides a clean boost for soft instruments and singers, while the 12 dB setting prevents overloading when dealing with high-volume instruments or loud vocal performances.
Class A Input Stage: The dBooster incorporates a Class A input stage that delivers crystal clean gain with minimal noise and self-distortion. This ensures a transparent and high-quality signal path for recording applications.
Low-Impedance Output: With a low-impedance output, the dBooster maintains signal integrity in both studio and live settings. It is capable of driving long cable lengths and handling challenging loads such as mic splitters and vintage-style preamps without loss of gain, increased distortion, or compromised headroom.
Compatibility with Royer Microphones: The dBooster is optimized for use with Royer R-121s, R-10s, and stereo SF-12s, delivering excellent results. It is also suitable for dynamic microphones like the SM7 and others.
Built in the USA: The dBooster is proudly built in the USA and shipped from Royer Labs' headquarters in Burbank, California.
Recording Soft Instruments and Singers: The 20 dB setting is ideal for adding clean gain when recording softer instruments and singers, enhancing the signal without introducing noise or distortion.
High-Volume Instruments and Vocals: Switching to the 12 dB setting is recommended for preventing overloading when recording high-volume instruments like electric guitars or during dynamic vocal performances.
Live Stages: The low-impedance output of the dBooster makes it suitable for live stages, driving long cable lengths and handling challenging loads with no loss of gain, increased distortion, or compromised headroom.
Compatibility with Royer Microphones: The dBooster is designed to work seamlessly with Royer R-121s, R-10s, and stereo SF-12s, ensuring optimal performance.
