Description
4 -Channel Class D Amplifier: 4 X 90w / Crossover For Semiactive Speaker
Features:
• High efficiency amplifier with 4 x 90 Wrms / 4 Ohm output power.
• Fully bridgeable and 2 ohm stable, inputs high and low level.
• Load resistor and ground lift selectable via jumpers, switchable active crossovers.
