Features:
1) Amplifiers of high performance and multi-channels. The newest optimization technique for the whole unit elaborately improved and designed. Auto test switching is adopted to delay the electric circuit for the start-up of the power supply, making the system working highly efficiently. Round transformer of high performance is adopted to provide electricity alone, reducing the chances to the lowest of intermediation distortion and noise. Through substantially reducing the AC power consumption and lowing the heating, we can finally reduce the running cost. It is the new generation power amplifier. Unique power output circuit makes the dynamic rang of the voltage wider. Unique big round transformer makes the power output stronger, harmonic wave distortion and intermediation distortion weaker. The transistor working in a safer area, enhance the reliability and durability. It also has the fan of low noise, which is controlled by thermo sensitive device of high speed and low speed.
2) 3 power supply bridge rectifiers are adopted, which are overpressure resistant. Along with the high dense radiator used for aviation, it guarantees that the amplifier can restore exquisitely, enhancing the product's load capacity and stability.
3) The amplifier circuit is improved and optimized through the traditional HiFi AB electric circuit. Medium-high frequency is natural and charming, extremely plump and smooth skinned, intelligent and of very good extensibility. It is of rare professional electric circuit of fever grade.
4) Imported spare part of low noise and high reversion is adopted for the IC. Precise resistance and capacity can ensure the electric circuit of fines and smoothness.
Whether you are a wholesaler, Distributor or rental company we at 3Twill bring you reliable, trustable, high premium quality power amplifiers but also maintain a reasonable and competitive price for our partners in building your brand name.
