XA3000
XA3000 is a two-channel power amplifier meticulously designed for the professional market. It adopts class H+ circuit design to eliminate the common Class H cross switching distortion. High-quality and sophisticated materials and craftsmanship ensure the high fidelity and high damping factor of XA3000. It can be used to drive various high-power speakers and monitor speakers that have critical requirements on the high-frequency performance.
It is widely used in fixed installations such as KTV, bars, nightclubs, multi-function halls and DJ.
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. XA3000 will not be interfered by peripheral electronic equipment, which effectively solves the headache of crosstalk.
Perfect Protection System
Limiter protection/ Soft-start protection/DC protection/Short-circuit protection/Overheat protection/Output overload protection
Class H+ Circuit Design Eliminates Cross Switching Distortion XA3000
Adopts latest Class H+ circuit to eliminate the Class H cross switching distortion. The result is the same low distortion as Class AB circuit design. XA3000 has less than 0.1% THD at 16KHz and the sound is so clean and
natural.
