Description
The Recoil Audio RL680.1 is a compact Class-D monoblock amplifier designed for subwoofer systems that need useful low-frequency power from a very small chassis. It is stable down to 1 ohm and includes adjustable low-pass, subsonic, and bass-boost controls for system integration.
At 14.4 volts, the amplifier is rated for 680 watts by one channel at 1 ohm, 500 watts by one at 2 ohms, and 260 watts by one at 4 ohms. Its wide 220 mV to 12 V low-level input range supports integration with many aftermarket source units and processors.
