Features
Unique Linear Limiter Protection Circuit (LXTM circuit) [Has won a national patent]
The protection value of the LXTM linear limiter protection circuit can reach 8V. It can track the dynamics of temperature, power and frequency in time and adjust the limiter strength automatically to ensure that the system always runs in a safe environment and ensures the dynamic effect of the entire audio system.
Unique and Efficient Crosstalk Shielding Design
When designing and selecting components in R & D stage, the anti-interference ability of the circuit was fully considered. XA2000 will not be interfered by peripheral electronic equipment, which effectively solves the headache of crosstalk.
