The dbx 540 is a single-slot 500-series tube microphone preamp that boasts pristine audio output, superior-quality high-end design at a value price. The dbx 540 features a Class A tube preamplifier, switchable phantom power, phase invert, selectable -20dB pad, and a super fast in-line optical compressor. The front panel includes a TRS microphone input—a standout feature typically not found on 500-series preamps.

The switchable (in/out) compressor provides adjustable attack and release, and when it’s in use, the on-board VU meter automatically changes from displaying master level to amount of gain reduction, so you can view the exact results of the compression being applied. Editing is done using our smooth, responsive hand-machined controls. And last but not least: The dbx 540’s audio circuit uses LME49720 ultra-low distortion/low noise Op Amps, for superb audio output.

Push and shape the tone of any microphone with the full-featured dbx 540!
