Features:

1)Able to remotely switch on/off, monitor loudspeaker temperature, driver voltage, current, set up DSP and remotely receive network audio signal with network software  (Refer to network monitor DSP technology data) on PC.

 2)Crystal HF, tight and strong LF, Class D amplifiers to drive HF and LF separately (bi-amp), accurate signal restore, patent design to ensure high performance like distortion, frequency response, transform rate,bandwidth and damping factor.

 3)Complete protection (short-circuit protection, over-current protection, over and under voltage protection,DC protection, power limit, temperature limit, long time output power limit, clipping limit). High efficiency and safe output dynamic compress function and temperature protect circuit. 

4)Coaxial driver, unique one-magnet-dual-loop technology, tweeter and bass diaphragm make the sound in the same axis, so that treble and bass sound synchronously, no time different, clear voice, high fidelity, and even sound field distribution, both horizontal and vertical dispersion angle are 120°.
