Design Introduction

The spacend zero power amplifier adopts 137mm large meter mono design, and the current advanced high efficiency class D audio amplifier circuit is applied. The class D audio amplifier module uses 400W purifi 1et400a power module originally imported from Denmark, The main power supply adopts hypex 1200W smps1200a400 audio special switching power supply imported from Holland, the PCB circuit board adopts a new processing technology to ensure the reliability of signal transmission, the input terminal adopts two groups of input of netrik nc3faav1 balanced socket and RCA socket respectively, the amplifier power supply system adopts two 10000uf nickel super for each channel The front board of the power amplifier uses independent power supply, talema power supply, lt317 / 337 and LT1085 / 1033 two-stage voltage stabilizing systems respectively. The main filter capacitors of the whole series use Nichicon super through audio fever capacitors, and the output of the amplifier uses WBT horn terminal to ensure the high efficiency and reliability of the system connection. The chassis is designed with all aluminum, and all transformers are sealed with epoxy resin to ensure that the vibration of the whole machine is controlled in the minimum range.
