Alpine R-Series Class D Bridgeable Multichannel Amplifier with Variable Crossovers Black R-A60F - Best Buy

Alpine R-A60F R-Series 4-Channel Digital Amplifier - 150 Watts RMS x 4 @ 2-Ohms The new R-Series amplifiers produce accurate imaging and dependable power. Use them with the R-Series speakers and amplifiers for a loud and fun experience. The R-Series Amplifiers have a diagnostic LED located behind the blue Alpine Jewell on the top of the amplifier. A Blue light means the amplifier is operating normally. A red blinking light means the amplifier is currently too hot for operation and needs to cool down. A solid red light can mean three things; 1. Amplifier circuit is abnormal. 2. Temperature is too high. 3. Power supply voltage is too high. The R-Series amplifiers utilize Alpine’s advanced amplifier platform that takes the classic Class-D amplifier circuit and adds dual post-filter feedback loops for unmatched accuracy and control. This technology., originally launched in the premium X-Series amplifiers, produces efficient power with enhanced dynamic range, qualifying the R-Series amplifiers to be Hi-Resolution Audio compliant.
