XH-M151 XR1075 Tone Board

Product Information:

The BBE sound effect enhancement processing technology can correct and recover the signal loss and phase deviation of the audio system due to various reasons, so as to make the sound reappear truly, and make the listener feel rich in high and low frequencies, with the sense of positioning, clarity and brightness close to the ideal scene effect. This is the magic weapon for the enthusiasts who pursue the true, good and beautiful music realm.

BBE chip – – – XR1075 is based on XR1071 and adopts a new bipolar technology, which makes its chip have lower noise coefficient, less total harmonic distortion, and smaller size (dual-inline 18-pin package), further simplifying peripheral components, better high and low frequency extension specificity, and wider adjustment range of high frequency resolution (resolution) enhancement and low frequency compensation than XR1071. The minimum working voltage of XR1075 is 6V, the typical value is 12V, the working current is 15mA, the adjustment range of high frequency resolution enhancement is - 0.5~+13dB, the adjustment range of low frequency compensation is - 0.5~+13dB, and the adjustment range of high and low frequency compensation is controlled by changing the input level of 4 (16) and 5 (15) pins respectively.

XR1075 has two BBE processing patent circuits with the same channel inside. The functions of each pin of XR1075 are as follows: pin 3 and pin 17 are the left and right channel signal input terminals, pin 9 and pin 11 are the left and right channel signal output terminals, pin 10 is the power input terminal, pin 1 is the power ground, pin 18 is the control terminal of BBE processing and straight-through selection switch (BBE processing when grounding), pin 2 is the reference voltage output terminal, which is used to output to pin 4 (16) and pin 5 (15) for high and low frequency compensation adjustment. Pin 6 (14) is the low-pass filter end, and pin 7 (13) is the high-pass filter end. Its effect is immediate, clear level of detail, and realistic and natural sound effect will come to your ears!
