Chip Type：AKM7735eq
Chip Introduction：
The AK7735 is a highly integrated digital signal processor, including a 24-bit stereo ADC with MIC gain
amplifiers, a 24-bit stereo ADC with input selector, two 32-bit stereo DACs, 2 stereo sampling rate
convertors supporting the sampling frequency up to 192kHz and dual DSPs for Audio/HF process. Each
DSP has 3072step/fs (when fs=48kHz) parallel processing power.
Functions: 1, intelligent sound adjustment, reverberation, sound field, bass, Liyin
2, sound field adjustment
3. EQ adjustment in stage 30
4. Delay setting
5. Setting of high-low pass filter
6, intelligent alto and bass regulation
DSP features: chip built-in dual DSP, support RCA5.1 channel output, medium and subwoofer can separately adjust the gain and frequency range, SUB heavy bass output, the maximum output amplitude of 5V (bilateral), 30 EQ adjustable, front and rear horn high-low pass filter. Intelligent sound effect can adjust reverberation, sound field, bass, beauty, simple user interface, easy to understand the operation.
Sound quality characteristics: medium and high frequencies clear and bright, distinct layers, authentic human voice, low frequency thick and powerful.
