Product Features:

Stereo/Parallel/Bridge Mono Mode,
User-selectable input sensitivity of -0.775V and 4V,
Electronically equalized RCA and XLR inputs; Binding post and Speakon output,
With DC protection, overload protection, short circuit protection, overheat protection, voltage limit protection, soft start protection, the machine performance is safer;
Using a large number of high-precision SMD devices, automated production process, product reliability is higher;
High-efficiency copper wire toroidal transformer with magnetic shielding layer is used to effectively resist interference;
Automatic variable speed fan, the fan runs at low speed to reduce the environmental noise when the machine is cooled, and the optimized heat dissipation system makes the machine performance more stable;
A variety of styles of panel design schemes are adopted to provide customers with personalized demand choices. 
Suitable for: KTV, bar, slow shake bar, conference room, stadium, multi-functional lecture hall, theater and so on.
