A-203GS Hot Sell Overseas karaoke system audio power amplifier

  A-203GS Hot Sell Overseas karaoke system audio power amplifier       Product Description   Technical Data FREQUENCY RESPONSE:10Hz-20kHz±0.5dB POWER CONSUMPTION:100W + 100W(8Ω)(AB), 100W + 100W(8Ω)(A) TOTAL HARMONIC DISTORTION (20Hz-20kHz): ≤0.1% INPUT SENSITIVITY:280mV S/N RATIO:90dB INPUT IMPEDANCE:47kΩ DIMENSIONS(W X H X D): 446 x 216 x 520(mm) WEIGHT(NET): 33kg Detail Description    A-203GS has transparent sound, solid construction,  plus the option of using it as a stand-alone power amplifier makes it irresistable. The preamplifier applies high-speed DC amplifier modules, which has outstanding performance in a wide frequency response, low distortion, vast and active dynamic. Volume is controlled by IC-CS3310 from U.S. Crystal Company. The error level between two channels is within 0.5dB, which is much lower than ±3dB error of  mechanical potentiometer. The power transformer is toroidal and filled with epoxy, which will reduce the vibration noise effectively. The fliter capacitor has a total capacity of up to 120,000 microfarads. 32 pieces of  high-power transistors compose the 100W class-A output stage. In order to activate the model's extreme performance, we use MKP audio non-polar capacitors, 1%  high-precision metal resistors, and parallel regulated power supply.  With CPU full-featured control and screen display, A-203GS has introduced the Hi-Fi amplifer into digital technolgy.
