Behringer 676 Tube Pre-amp and Compressor

Full Description

Classic tube warmth with premium components

The Behringer 676 features a high-quality tube preamp with 12AX7/ECC83S and 12AT7/6072 tubes, delivering smooth, warm sound with rich harmonic detail. This design is based on the legendary 6176 preamp, making it ideal for vocals, instruments, and even full mixes. Whether you want subtle saturation or full-bodied tube warmth, the 676 gives you the flexibility to dial in the perfect tone.

Custom-built Midas transformers ensure a high-fidelity signal path, enhancing clarity and depth while minimising noise. This premium component selection makes the 676 a powerful tool for professional and home studios alike.

Fast, responsive FET-style compression

The built-in compressor is modelled after classic FET designs, offering quick, musical dynamic control. With an ultra-fast attack time (as low as 20 microseconds) and adjustable release (50 to 1100 milliseconds), it captures transients with precision, keeping performances tight and controlled.

Ideal for vocals, drums, bass, and more, this compressor adds punch and consistency without sacrificing natural dynamics. Whether used subtly or for aggressive peak limiting, it ensures a professional, polished sound.

Flexible signal processing options

Operate the preamp and compressor separately or together for maximum versatility. The rotary input selector switch allows you to choose between multiple impedance settings, optimising the response for different microphones and instruments.

Further shaping options include a 2-band shelving EQ with switchable filters, allowing you to sculpt the tonal balance before recording or mixing. Additional controls like a switchable pad, polarity reverse, and 48V phantom power provide full compatibility with a wide range of audio sources.

Built for studio and stage

Housed in a rugged 2U rackmount chassis, the Behringer 676 is designed for both studio and live use. Transformer-balanced XLR inputs and outputs ensure reliable connectivity, while the vintage-style meter provides clear visual feedback for gain reduction and output levels.

The auto-ranging universal power supply makes it easy to use in different locations, ensuring consistent performance wherever you go. Whether you need a high-quality front-end for your studio setup or a reliable outboard processor for live performances, the 676 is built to deliver.
