Microphone Preamp Behringer 1273 with 48V Phantom Power and up to 60 dB Gain

Behringer 1273 is a microphone preamp designed to provide clean signal amplification for condenser and dynamic microphones. The unit offers 48V phantom power to supply studio condenser microphones and a gain range that extends up to 60 dB, enabling sensitive level adjustment for a wide variety of mic sources. Its compact design fits into desktop setups, broadcast racks or portable recording rigs and is aimed at improving input level, reducing noise and preserving signal clarity for recording, live sound and broadcast workflows.

Advantages

The preamp supplies stable 48V phantom power for compatible condenser microphones and offers up to 60 dB of gain to accommodate low-output sources. Precision gain control allows users to set input levels that minimize noise and prevent clipping. The device is built for straightforward integration with mixers, audio interfaces and PA systems, delivering transparent amplification with minimal coloration. Its simple control layout and robust connectors support reliable operation in studio and live environments.

Suitable for

• Home and project studio vocal and instrument recording
• Podcasting and voiceover production
• Small live sound reinforcement and PA setups
• Broadcast and streaming applications
• Connecting ribbon, dynamic and condenser microphones that require adjustable gain

Key specifications

• Phantom power: 48V for condenser microphones
• Maximum gain: up to 60 dB
• Input types: microphone-level input compatible with dynamic and condenser mics
• Output: line-level output for connection to mixers, interfaces or amplifiers
• Noise performance: designed for low-noise signal amplification
• Controls: precision gain control and simple front-panel interface

How to use

Connect the microphone to the microphone input and enable the 48V phantom power if using a condenser microphone. Route the line-level output to your audio interface, mixer or PA input. Start with the gain control set low and gradually increase until the signal reaches a healthy level without clipping. Monitor the signal with headphones or meters and adjust gain to balance level and noise. If the source is a high-output mic, reduce gain to avoid distortion; for low-output sources, increase gain to achieve the desired recording or broadcast level.

Usage recommendations

Use shielded XLR cables for best noise rejection, engage phantom power only when a condenser microphone requires it, and avoid rapid gain changes while recording to maintain consistent signal levels. Regularly check connections and meters to ensure optimal performance and low noise.
