Sound Pure's Take

Condition: Used, Excellent

Engineered for high-power bass amplification, the Ashdown ABM600 Dual VU Meter delivers 600 watts into a 4-ohm minimum load. Weighing 12.5 kg with dimensions of 135 mm × 474 mm × 320 mm, its hybrid architecture combines a solid-state power section with a single 12AX7 preamp tube. Input options include High (10kΩ, 150mV) and Low (10kΩ, 300mV–40V p-p) instrument jacks alongside a 22kΩ line input. Audio performance yields a frequency response of –3dB at 17Hz–30kHz. I/O connectivity comprises four Jack/Speakon speaker outputs, a 600Ω balanced DI output (0dBu nominal), a 22kΩ tuner output, and a 22kΩ effects loop (send/return at 0dBu nominal), operating on 115–230V mains power.
