PRODUCT FEATURES

DOLSI AT Series are digital power amplifier with Class D circuit category, a new milestone in amplfier development. PFC ( Power Factor Correction) technology is used in AT series . So the amplifiers can work well in power supply 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 (PFC), 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 to applications in high power output in live show, outdoor event, stadium,

and flow performance.
