PowerMatch® PM4250 Configurable Amplifier

PowerMatch® PM4250N Amplifiers allows each 4-channel loudspeaker block to be configured as Mono, V-Bridge, I Share or Quad modes, allowing the total available power of the amplifier block to be allocated to one or more output channels. The amplifier is capable of driving both low impedance and 70/100V loudspeaker loads directly. The PM4250 offers multiple channel and power options, an integrated audio DSP, front panel interface and USB connection. Efficiently manages the current drawn from the AC mains, allowing the amplifier to drive loudspeakers to maximum output longer without power fluctuation. Auto-Standby/Auto-Wake function automatically enters/exits Standby Mode, allowing the system to consume less power. Its proprietary design combines Class-D efficiency with a unique current and voltage feedback loop circuit that continuously monitors and controls both the current and voltage delivered to the loudspeaker load. Independent of power level and load impedance, the amplifier consistently delivers the widest possible dynamic range, frequency response and lowest possible distortion. This highly efficient amplifier design delivers sustainable and repeatable low frequency response
