Utilizing ADI high-end professional DSP main chip with 24 independent channels.
Each channel supports precise settings - crossover, gain, 31-band EQ, delay, phase, and mixing. Allows millimeter-level tuning for every frequency and speaker position, effortlessly creating an exceptional 3D stereo sound field.

Equipped with the AKM5704 ADC chip
for mastering-grade analog-to-digital conversion (192kHz/32bit)

Provides a wider range of high-level input voltage options
28VPP/32VPP/50VPP for various vehicle models.

The DAC section utilizes Texas Instruments' Burr- Brown branded PCM1681 chip for digital-to-analog conversion.
The excellent sound quality bearing the BB logo has gained widespread recognition from audiophiles worldwide.

Direct DSP digital signal input, lossless amplification output by digital power amplifier chip, delivering exceptional sound quality.
The I2S digital signals output from the DSP directly enter the digital power amplifier chip, eliminating the need for redundant DAC (digital-to-analog) and ADC (analog-to-digital) signal conversions in between, achieving true lossless output with extremely high signal fidelity.

The 24-channel output adopts Class AB + Class D amplification circuits.


Provides separate optical/coaxial input signal interfaces as well as an expandable 5.0 Bluetooth module + OTG direct connection
Diverse digital signal input interfaces such as optical, coaxial, expandable Bluetooth module, and OTG interface offer a more comprehensive range of usage scenarios.

The all-new optimized PC tuning software UI interface and A2B setup interface
The newly designed and optimized settings interfaces for EQ, mixing, delay, etc., make the tuning process more effortless and efficient. Through the connection with the A2B decoder box, it can precisely cater to different vehicle models. It can directly decode and transmit all multi-channel digital signals from the original car audio system without any loss.

Personalized low-frequency dynamic loudness enhancement function
The software can automatically compensate for the dynamic range of sound, solving the issue of weak bass effects during low-volume playback. It makes the bass fuller and enhances the dynamic balance.

Personalized spatial panoramic sound function
By analyzing and retrieving signals from different channels, introducing appropriate delays and phase changes, it simulates the time and phase differences of sound reaching both ears, allowing the listener to perceive sound coming from multiple directions, thus achieving a 3D stereo effect.

Built-in activatable energy-saving mode
When the system detects no external signal input for a long period, amplifier will automatically turn off to reduce battery drain and save energy effectively.

The tuning software adds three new real-time monitoring functions
