BL-450A Two-way Power Amplifiers

This series of 2-channel professional power amplifiers has a strictly controlled quality system in terms of quality, and the reliability of use in harsh environments can be guaranteed. The sound quality is delicate and sweet, suitable for various occasions.
1. This series power amplifier adopts compact 2U body design, optimized AB circuit, stereo, bridge, parallel transfer switch, and perfect protection design
2. Signal coupling path: professional audio grade electrolytic capacitor is used. The electrolytic paper of this series of electrolytic capacitors is made of natural silk medium, with thick bass and low distortion of middle and high tones. It is a professional audio capacitor
3. Power filter circuit: professional audio electrolytic capacitor is used The series resistance of the capacitor is low and the ripple current is large. The sound quality and color are sweet, the low frequency is thick, the full frequency is fresh, transparent, and the level is good, the medium frequency is natural, smooth, and the high frequency is clear.
4. Power amplification part: The power tube uses MN1526 and MP1526 pairs of tubes. This pair of tubes is a high-power tube specially developed by "Sanken" for the audio power amplifier. Its gain and linearity are of the highest level. Its sound is very dense and grainy, and its density is also very high. The sound quality is the best; Its power reaches 150W, and the instantaneous maximum output current is more than 25A. The tunnel radiator and dual fan cooling system are used for the heat dissipation part, ensuring the long-term and stable operation of power amplification.
The customer's sense of music is getting higher and higher, and the market competition is getting fiercer. The cost-effective is the winning weapon.
