D.POWER Series

D.POWER900

The D.Power series power amplifier is the latest generation of GRF AUDIO after years research & development in the switching power supply technology. It is featuring smallest size and extremely lightweight with excellent sonic performances. The stable power management ensures that even it is in harsh environment such as sharply decrease in the voltage but still able to meet the full power output and distortion-free.

D.Power series amplifier provides adjustable gain and VPL at rear panel, as well as the selectable input sensitivity and operation modes such as Stereo/Parallel. All those functions enable users to obtain optimum performance and usage. Besides that, efficient cooling system has been built by designing thousands of tiny cooling tank, and two speedy cooling fans transversely mounted inside the heat conduction area which results in excellent airflow and achieve good production to the capacitors.

D.Power series amplifier including 2CH such as D.POWER900 & D.POWER1500, 3CH such as D.POWER309 and 4CH such as D.POWER406 & D.POWER412. It covers most of the applications , best choice for Two way, Three way or Four way speaker system .
