Detailed control for every input signal

The preamp offers input selection for microphone, line and Hi-Z signals with switchable impedance, a gain range of up to +64 dB as well as a switchable pad, phantom power and phase inversion. The sound is shaped via a 2-band shelving EQ with switchable frequencies (low: 70/100/200 Hz, high: 4.5/7/10 kHz) and a finely graduated boost/cut control in 1.5 dB steps up to ±9 dB. The subsequent compressor offers extremely fast attack times from 20 microseconds, a variable release time of up to 1100 milliseconds and a flexibly selectable ratio from 1:1 to all-in (more than 100:1) - ideal for precise transient control for vocals, Bass or drums. A switchable VU meter displays either gain reduction, the preamp output or the output level of the compressor and can be precisely adjusted using an internal calibration trimmer.

Series or individual operation via split/join

The split/join function allows the preamp and compressor to be operated either separately or in series - a flexible solution for different signal routings in a professional environment. The robust 2U rack housing offers space-saving integration in studio environments, while the integrated switching power supply with automatic voltage adjustment ensures a reliable power supply. All inputs and outputs are transformer-balanced and accessible via high-quality XLR connectors, ensuring the highest signal quality and compatibility.

With its authentic tube sound, fast compression architecture, versatile EQ and high-quality workmanship, the Behringer 676 offers a comprehensive and reliable solution for professional audio production at the highest level.
