Product Description

NSLBM-4120 4-channel full-range class D amplifier is IPX5-rated for waterproofing and features a rugged mechanical structure (ME structure) that withstands diverse environments, ensuring safe and stable operation in damp and dusty conditions. It is particularly suitable for outdoor audio and automotive applications. The NSLBM-4120 delivers 80W RMS power per channel into a 4-ohm load, increasing to 120W RMS into a 2-ohm load, with distortion below 1%. This ensures clear, detailed, and dynamic sound, meeting the high-fidelity and high-power requirements of multi-channel systems. A DIP switch allows for flexible crossover mode selection. The built-in low-pass filter (LPF) supports 120Hz and 80Hz settings, while a high-pass filter (HPF) is adjustable from 50Hz to 250Hz for 2-channel operation, allowing precise adjustment to suit speaker and system requirements, enhancing overall audio performance.
