Housed in a convenient 500 series lunchbox-style chassis, the dbx 580 Mic Preamp offers up to 60 dB of low-noise amplification for even the most esoteric microphones. The device will transform the microphone's low-level output signal to a high-level, high-current output for direct connection to the line-level input of a mixer, sampler, or other recording medium.

The pre features a variable frequency low-cut filter with both low and high detail equalization controls. It also features a 20 dB pad, a polarity invert button, selectable +48V phantom power, a front-panel instrument input, VU metering, and a peak indicator LED.
