Описание товара
professional Stage amplifier board powerful mono power amplifier board hifi stage amplifier board mono tube amplifier Assembled 1500W Powerful amplifier board/mono amp board stage amplifer board
(not include heatsink/power transistors)
Overview:
Circuit boards to adopt thick mmFR 2.0-4 high-grade double-sided PCB, with metal film resistor is 1% error precision resistance imported from Taiwan,Small capacitance all adopt the original package, coupled with high capacitance.This board materials standards, circuit design is reasonable, the high sex ratio, pure sweet sounding music, and details.Small volume can push hard to push hi! Beep bass have to do to with low distortion, low noise, high pressure and mute switch machine, chip inside with perfect output over-voltage protection, overload protection, short circuit protection.Pure bright timbre, component materials and theory of than. Circuit design more perfect.High sex ratio, close to the speaker It is hard to hear the noise.
The plate for the pursuit of clear, pure tone color, specially adopt high-frequency transistor circuit design, the timbre transistor that clear and fine to carry out in the end, driver stage audio with the Toshi ba company dedicated to the tube TTC5200, TTA1943 to post.
Enter the name to use IC JRC5532D bear power output level 12 to Toshi ba audio dedicated to tube TTC5200, TTA1943 parallel output that are really original matching tube, or no resistance to high pressure and guarantee the effect.
protection circuit:
In order to protect the power amplifier on the precision and expensive components, as well as you that is more precious speakers,This amplifier matching power panel precision of all-round protection circuit is designed.First is output over current and short circuit protection, USES the advanced float type sampling circuit,Its characteristic is the sampling level as the output voltage fluctuations and,Only when the output current more than set value(due to the sampling points with the output voltage fluctuations, so whatever the current value in which a phase of the output waveform, the protection circuit can accurately capture every flow or short-circuit moments, decisive turn off output relay, guarantee the normal work of the circuit, because it is the same float type, so it would not misoperation). Conditions of use and basic parameters: In the pursuit of the highest degree of separation, the amplifier board adopts mono structure (push + power level) and two pieces for each channel (push plate installed on the top of the power board).Stereo needs four pieces. Each piece has a independent protection circuit So the power supply voltage range is very wide, plate between the double 50 v to 135 v dc can be reliable work.(as for power transformer power, the bigger the better, of course). This is especially important when enjoy big dynamic music. It will make you really realize what is shaking the thrill of feeling. Use voltage :Dc double 28-135v,To separate the power protection circuit,Pursue big dynamic and power, it is recommended to use dc 110V,The power to more than 900 w. This is the newest version:(Circuit layout will be some differences,Everything is to get a higher quality sound,We will ship the latest version)
If high power work for long time,Please do add a cooling fan.
Package List: 1500W Assembled mono Power Amplifier board X 1 (not include heatsink&power tubes) .
The board will be tested well before sending out.
