XH-M151 XR1075 Tone plate BBE digital audio processor Power amplifier front board module

The latest high-resolution BBE chip launched by EXAR Corporation in the United States - XR1075. XR1075 is a new bipolar technology adopted by the company based on XR1071, which reduces the noise coefficient and total harmonic distortion of its chip. In addition, the chip has a smaller size (double inline 18 pin package), further simplifies peripheral components, and has better high and low frequency extension characteristics. The range of high-frequency resolution (resolution) enhancement and low-frequency compensation adjustment is wider than XR1071. The minimum working voltage of XR1075 is 6V, with a typical value of 12V and a working current of 15mA. The high-frequency resolution enhancement adjustment range is -0.5~+13dB, and the low-frequency compensation adjustment range is -0.5~+13dB. The high and low frequency compensation adjustment ranges are controlled by changing the input levels of pins 4 (16) and 5 (15), respectively.

There are two BBE processing patented circuits with the same channel inside XR1075. The functions of each pin of XR1075 are as follows: pin 3 and pin 17 are the input terminals for left and right channel signals, pin 9 and pin 11 are the output terminals for left and right channel signals, pin 10 is the power input terminal, pin 1 is the power ground terminal, pin 18 is the control terminal for BBE processing and direct selection switch (BBE processing when grounded), pin 2 is the reference voltage output terminal, used to output to pins 4 (16) and 5 (15) for adjusting high and low frequency compensation. Pin 6 (14) is the low-pass filter terminal, and pin 7 (13) is the high pass filter terminal. The effect is immediate, with clear levels of detail and realistic and natural sound effects surging into your ears!
