Product Description

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.
