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.

Q1:How's the delivery time?

A: Usually it will take about 30-35 days for production.

Q2: Can you produce according to customers'design?

A: Sure, we are professional professional ktv audio manufacturer,OEM &ODM are welcome.

Q3: What's the payment term?

A: We accept T/T, 30% deposit and 70% balance before shipping.

Q4: Tell me the standard of package?

A: For the small capacity, inside filling the foams, outside using carton, but for big capacity, we should use strong wooden case for protection.
