The ABM RPM-1 EVO II is a high-quality preamp for those wanting the ultimate rackmount rig!
The footswitchable subharmonic generator tracks the main signal precisely and reproduces it an octave lower. A subharmonic level control lets you add just the right amount of low-end reinforcement--everything from a subtle thickening of the sound to unbridled, bone-crushing tone.
The ABM RPM-1 EVO II also features a front panel-mounted balanced direct out with pre- or post-EQ switching, a sub-bass output, tuner output, FX loop, and a line input for connecting an external sampler or sound source. Output muting cuts the signal from the direct out but leaves the tuner output live, allowing silent tuning. The upgraded power section has faster transient attack, more headroom, and even less noise.

- Switchable active/passive input
