??Max Power Rating: 4000 Watts ??Power Rating: 4 ohms: 1000 watts x 1 | 2 ohms: 2000 watts x 1 | 1 ohm: 4000 watts x1 ✅Extreme Efficiency: Class D amplifiers utilize a small but efficient MOSFET transistor. These amplifiers are designed to process digital signals with a lower power consumption which means they lose less energy to heat dissipation. Reducing heat dissipation means Class D amplifiers have a higher efficiency rate of 90% compared to their AB class counterparts that feature an efficiency rate of 50 to 70%. ??User Control: Belva amplifiers provide a world-class user control experience. While other amplifiers on the market only feature a fixed bass boost switch, all Belva BX-Series Monoblocks feature a variable Bass EQ. This allows the user to fine tune the bass and gain with even more precision. ??One Size Fits All: All BX-Series amplifiers feature both high-level and low-level inputs. High-level (speaker level) inputs accept the signal from the speakers, while low-level (RCA) inputs accept the signal from the pre-amp outputs of the source unit.
