PRODUCT FEATURES
 
 
DOLSI  AT Series 4 channel digital power amplifier with Class D circuit category, is a new milestone in amplifier development.  
The amplifier is integrated with PFC( Power Factor Correction) and nice stability in voltage range 90-260V.
Advanced Class D PCB module and SMPS power supply module  are used to obtain high efficiency and stability.
It has very high power density, which makes the amplifier to reach powerful output in a very small shell space. 
 
 
.  Unique and elegant enclosure design.
.  Compact structure with only 1U height and 9" depth and light weight, easy to move and install.
.  Fixed switch frequency Class-D  PCB module.
.  Soft resonant switching power supply LLC  module.
.  Active power factor correction technique (FPC), can work with high stability under full          
   voltage range 90-264V .
.  High efficiency loudspeaker EMF absorption system.
.  Unique peak clipping limiter and ripple Elimination.
.  Low electricity consumption.
.  Nice cooling system with quality fans to make wind flow  front to the rear.
.   Accurate volume control, switch on/off, signal, clip and protection LED light  in front panel.
.   Fully automatic protections against  direct current protection, over heat, over load, on/off switching, RF and amplitude limit. 
.   XLR balance input and professional SPEAKON output connectors.
.   Stereo ,bridge and mono mode selection pull switch is set on back panel.
.   Good choice for applications that need high power output , for example, live show, outdoor event, stadium, flow performance ... etc.
