Features

● Adopt two forms of circuit: preamp and power amplifier.
● Adopt TI company’s high performance audio operational amplifier
OPA2134 signal process as preamp; With low noise, low distortion and high conversion rate.
● Adopt NXP high efficiency Class D amplifier TFA9815T as power amplifier; BTL output to make low voltage and large current.
● Designed with two sound channels with different carrier (550KHz / 600KHz), realize hi-fi conversion and at the same time avoid mutual interference.
● "0" dead zone design and its perfect protection function: overheating, over-current, over-voltage, undervoltage, with own detection protection when boot up.
● Differential input level and combined with adjustable negative feedback circuit, ensure low noise and low interference and low distortion
● On/off mute function
● Use closed APLS potentiometer, ensure low noise and good channel balance
● RCA and 3.5mm two audio input, for convenient to connect.
● Minimum output 4 ohm adaptive impedance.
● Combined with Banana plug/terminal output interface, convenient to connect with speakers.
