Mono Block Class D Amplifier

NSLBM-1300 Mono-block class D amplifier is designed for outdoor and automotive applications, offering excellent waterproof performance (IPX5 rating), ensuring stable and reliable operation in rainy and humid environments. It easily fits into confined spaces and features a rugged mechanical structure (ME structure) to withstand challenging environments. A control panel equipped with DIP switches allows users to flexibly configure various operating parameters to meet diverse needs. Extensive audio adjustment features include a switchable low-pass filter (LPF) between 120Hz and 80Hz, and a switchable high-pass filter (HPF) between 50Hz and 250Hz, allowing users to flexibly adjust the amplifier based on their speaker configuration and listening preferences. Gain controls on both front and rear channels allow for precise volume adjustment. Mono models also feature a 16Hz to 47Hz subsonic filter, effectively filtering out unwanted low frequencies to protect speakers from damage while enhancing bass purity. A built-in signal sensing function automatically detects the input signal and activates the amplifier, streamlining operation. The 12V remote output interface facilitates linkage with other devices and expands the functions of the audio system.

NSLBM-2150 is a high-performance, two-channel, full-range Class D car amplifier designed for users who demand powerful sound quality and exceptional protection. Its IPX5 waterproof rating and rugged mechanical construction (ME structure) ensure stable operation in harsh environments, making it ideal for outdoor and in-car audio system upgrades. The NSLBM-2150 delivers 100W RMS power per channel into a 4-ohm load, increasing to 150W RMS into a 2-ohm load, with sub-1% distortion, delivering a clear, rich, and dynamic audio experience, meeting the dual power and sound quality demands of various audio systems. The product features a pre-wired pigtail harness, simplifying installation and reducing wiring complexity. A DIP switch control panel allows for flexible crossover mode selection, and a built-in low-pass filter (LPF) with a selectable 120Hz or 80Hz setting allows users to adjust the frequency response and optimize sound quality based on their speaker configuration.

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.

NSLBM-5600 amplifier combines IPX5 waterproof certification with a rugged mechanical structure (ME structure) to ensure stable operation in wet, dusty, and complex environments, making it ideal for demanding applications in automotive and outdoor audio systems. The NSLBM-5600 delivers 75W RMS power per channel into a 2-ohm load, with the mono subwoofer delivering a powerful 300W RMS. This ensures pure, detailed, and dynamic audio, delivering a stunning sound experience. A DIP switch on the control panel allows users to flexibly switch between crossover modes. The low-pass filter (LPF) supports 120Hz and 80Hz settings to meet the needs of different speakers. In two-channel mode, the high-pass filter (HPF) frequency range is adjustable from 50Hz to 250Hz, facilitating precise audio crossover and optimization. The mono subwoofer channel also has a subsonic filter from 16Hz to 47Hz, which effectively filters out invalid ultra-low frequencies, protecting the speakers while enhancing the purity and impact of the low frequencies.
