dbx 580 Mic Preamp (500 Series Module)

Professional 500 Series Microphone Preamp for Studio and Broadcast Use

The dbx 580 is a high-performance microphone preamp designed for engineers who need clean, reliable gain in a compact 500 series format. It delivers up to 60 dB of low-noise amplification, making it suitable for dynamic, condenser, and ribbon microphones used in recording studios, broadcast facilities, and installed sound systems.

Clean Gain with Low-Noise Signal Path

Built around a carefully engineered low-noise design, the dbx 580 ensures quiet operation even at high gain levels. This makes it well suited for capturing subtle vocal details, acoustic instruments, and low-output microphones without introducing unwanted hiss or coloration.

Tone Shaping with Low-Cut Filter and Detail Controls

The preamp includes a variable-frequency low-cut filter that helps reduce rumble and low-frequency buildup at the source. In addition, dedicated low and high detail equalization controls allow subtle tonal adjustments during tracking, helping recordings sit more naturally in a mix without heavy post-processing.

Flexible Controls for Professional Recording Workflows

To accommodate a wide range of sources and recording situations, the dbx 580 features a 20 dB pad for high-output signals, polarity inversion for phase correction, and switchable +48V phantom power for condenser microphones. These controls make it easy to adapt quickly during sessions.

Front-Panel Instrument Input for Direct Recording

A convenient 1/4-inch front-panel instrument input allows direct connection of guitars, basses, and other line-level or instrument sources. This makes the dbx 580 a practical choice for studios that want a single preamp module capable of handling microphones and instruments alike.

Accurate Metering for Gain Staging Confidence

The integrated VU meter and peak indicator LED provide clear visual feedback, helping engineers set proper gain levels and avoid clipping. This metering setup supports accurate gain staging during tracking and ensures consistent signal levels throughout the recording chain.
