Features
Unique Linear Limiter Protection Circuit (LXTM circuit)
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. XA800 will not be interfered by peripheral electronic equipment,
which effectively solves the headache of crosstalk.
