## Summary description

DONNER RB-1 is a compact microphone preamp designed to boost microphone-level signals and provide impedance matching for improved signal quality. It serves as an inline preamplifier for dynamic or passive microphones, helping to increase gain before recording or live sound processing. The unit is intended for use in home studios, rehearsal spaces, portable recording setups and live sound applications where additional clean gain is required.

## Long description

DONNER RB-1 is a compact microphone preamp designed to boost microphone-level signals and provide impedance matching for improved signal quality. The inline preamplifier increases gain for dynamic or passive microphones, reducing the need for excessive channel gain on mixers or audio interfaces. Its compact form factor makes it suitable for home studios, rehearsal spaces, mobile recording setups and live sound situations where a clean, controlled boost is required before recording or further processing.
Advantages
The RB-1 delivers transparent gain with low noise and preserves the character of the connected microphone while increasing signal level. Its impedance matching improves frequency response and microphone sensitivity in many common setups, and the small enclosure allows easy placement in signal chains without adding bulk. The simple operation and rugged build make it practical for both studio and live use.
Suitable for
 Boosting dynamic or passive microphone signals for recording
 Providing a clean inline gain stage for live performances or rehearsals
 Improving microphone-to-interface impedance matching in home studios
 Portable and field recording setups where additional preamplification is needed
Key specifications
 Device type: compact inline microphone preamp
 Primary function: signal gain and impedance matching for dynamic/passive microphones
 Form factor: small, portable enclosure suitable for inline placement
 Intended use cases: studio recording, rehearsal, live sound, portable recording
 Performance focus: low-noise gain and neutral signal character preservation
How to use
Connect the microphone to the RB-1 input and then connect the RB-1 output to your mixer, audio interface or recorder. Adjust the gain on your downstream device as needed, keeping the RB-1 inline to provide the required boost and impedance matching. The unit is intended to be used with dynamic and other passive microphones; it does not provide phantom power. For live setups, place the preamp close to the microphone source or at a convenient point in the signal chain to minimize cable length and potential interference.
Usage recommendations
Use the RB-1 when microphone signals are weak or when improving microphone sensitivity and tonal consistency is needed without adding coloration. Avoid using it with condenser microphones that require phantom power unless an external phantom supply and proper routing are provided. For best results, pair with a quality cable and set input gain on your interface or mixer to achieve a clean level without clipping.
