For those requiring an integrated solution, the ABM 500RC EVO III is a rack-mounted version of the standard ABM 500 EVO III Head, with a stunning, polished chrome panel. Three straightforward rotary tone controls provide 20dB of EQ cut and boost at 60 Hz, 660 Hz and 5 kHz. These controls are supplemented by two pairs of additional sliders giving 15dB cut and boost at 180 Hz, 340 Hz, 1.3 kHz and 2.6 kHz. The EQ can be switched in/out by a footswitch, enabling players to go from a flat fretless sound to a boosted sound by taking advantage of a favorite EQ setting. A single input is switchable for passive and active instruments with a blend of solid state and dual triode tube preamps stages. This can also be preset and selected via footswitch, providing access to a massive range of clean, warm and overdriven tones.
Also footswitchable is the on-board compressor and the mighty Ashdown sub-harmonic generator, which precisely tracks the main signal and reproduces it an octave lower. A sub-harmonic level control enables the player to add just the right amount of low-end reinforcement - everything from a subtle, thickening of the sound to unbridled bone crushing tones. The ABM500RC EVO III features a front-panel mounted balanced DI output with pre or post EQ switching, a sub-bass output, a tuner output, an FX loop and a line input for the connection of an external sampler or sound source. Output muting cuts the signal from the DI output but leaves the tuner output 'live', allowing the player to tune up in silence. A new upgraded power section has faster transient attack, more headroom and even less noise.
