Product Q & A
Review
Size : 184mmX117mmX70mm
with 4pcs Top audio 10000uf 80V capacitance.
Power transistor using original IRFP4227.Inductance use Japan 7G31A-22UH, a greater ability to withstand the current, lower internal resistance.

Package inlcude Assembled IRAUD2000 stereo power amp board X 1pcs
1 amplifier has overcurrent and short circuit protection, thermal protection and over-voltage protection, safe and reliable! To improve security, proposed increase speaker protection board, just in case.
2 amplifier to work in high-voltage power state (DC voltage> 60V), inductance and radiator will be a little hot, if ventilation is poor (eg in a sealed box), should be added to enhance the cooling fan.
3 If you need a long power output, rectifier bridge needs additional radiator, another proposed increase fan assisted cooling.
4 This is a two-channel amplifier design, can bridge.
5 amplifier board if it is installed in the speaker, should try to stay away from the speaker, the best shielding.
6 DC power amplifier board, the board did not take the rectifier bridge, need additional bridge rectifier, and the rectifier bridge should be added to the radiator.
Efficiency: Different output power efficiency of different, high-power ultra-high efficiency, 300W output reached more than 90%
IRAUD2000 is my company recently developed ultra-high-power top-class D amplifier, this amplifier board can operate in dual channel mode or bridged mono mode, easy to use.
It is using US International Rectifier's Class D amplifier chip IRS2092S and promote high-speed high-current and low RDS (on) MOSFET IRFp4227 do output, making the amplifier output power greater and smaller distortion. Dual channel mode maximum undistorted maximum output power can be dual-channel 350W / 8ΩX2 700W / 4ΩX2; bridging can also output up 1200W / 8Ω, 2000W / 4Ω power, it can be compared to non-ordinary power amplifier! This power is the actual effective power without distortion, not instantaneous maximum power!
The amplifier has consistently adopted a pure DC amplification design, frequency response reaches 0-50KHz! Pure DC amplifier canceled coupling capacitor, the Class D amplifier hardest bass are doing very well, dive deep enough strength, jumping ability is also very. Moreover, the abolition of the coupling capacitor for alt also has a great positive impact, simply upgrade the same.
IRAUD2000 amplifier board development stage is long, because we hold a highly responsible attitude to customers tuning, after each of the above components are adjusted after repeated scrutiny audition and settle down, but all use the boutique fever components: the first stage of power supply decoupling capacitors are Japanese chemical pitched capacitor 1500uF / 6.3V, LC filter circuit output, using the original Japanese imports large current shielded inductors, RIFA fever capacitor 0.47uF / 200V, main filter capacitor Japanese origin chemical capacitance .....
