The ZK-AS21 power amplifier has the functions of bass\nfrequency adjustment, bass volume adjustment, left and right high and low bass\nindependent adjustment functions, and can modulate your favorite sound effects\nat any time. KIND TIPS When the audio signal input is large enough and the\npower supply voltage\/current is large enough, there will be enough output\npower! The higher the power supply voltage, the greater the output power, and\nthe smaller the speaker impedance, the greater the output power! Please make\nsure that the power of the adapted power supply is greater than the actual\nworking power of the power amplifier! When you have multiple amp boards, do\nyou always get confused which amp board you are connecting? This problem no\nlonger exists. You only need to customize the Bluetooth name of each of your\npower amplifier boards through the APP. Is your bluetooth device always\nconnected by the next door or other people? This problem will also be gone,\nbecause you can set a password for the power amplifier board through the APP?\nCan annoying beeps be suppressed? No problem, you just need to turn off the\nbeep through the APP. Are there more features? Yes, the APP also comes with 10\nkinds of natural sound effects, you can create a natural and peaceful\natmosphere for yourself by combining these sound effects at will, especially\nwhen you are working, reading, meditating, sleeping, this function brings The\nbenefits will be particularly prominent. PLEASE NOTE THAT: The APP is\ncurrently only supported on the Android system.

Turn the volume down to the lowest level and then turn it off, it is\nnot easy to damage the speakers and power amplifiers. The mechanical switch\ncan be turned off with one turn, no need to long press and wait, which is\nconvenient and fast. Dual TPA3255 Chip This Bluetooth power amplifier uses two\nTPA3255 high-fidelity power amplifier chips, and the power output of a single\nchip can reach 220w2. At the same time, our engineers bridged another chip\nand used it for the subwoofer channel, which allowed the subwoofer to obtain a\npower output of up to 350W. Low Speed Fan This power amplifier board uses a\nlow-speed cooling fan, it has a long life, and it has almost no noise. The\ngood heat dissipation effect allows the power amplifier board to continuously\noutput high power. Multiple Input Methods ZK-AS21 has a variety of input\nmethods: Bluetooth\/AUX\/USB flash drive\/USB sound card, etc. It is suitable for\nmobile phones, TVs, laptops, MP3 and other scenarios, and can meet your daily\nneeds. You can choose the way you like connect.
