Description
The Kicker LX500.4 is a premium full-range Class-D four-channel amplifier designed for high-output front-stage, rear-fill and active speaker systems. It delivers 125 watts per channel at four ohms, 225 watts per channel at two ohms, or 450 watts per channel when bridged into four ohms.
FIT+™ differential inputs accept low-level or speaker-level signals up to 40 volts, while gain-match LEDs and selectable Linkwitz-Riley or Butterworth crossover functions simplify accurate system setup. The included LX Control Center provides convenient monitoring and adjustment.
