BL-450A Two-way Digital Power Amplifier
Description:
BL - 450A is a two way digital circuit manipulation power amplifier that can amplify weak electric signal from signal source, and make loudspeaker produce sound. The maximum output power of BL - 450A is up to 900W, which ensures maximum power margin, and further makes 5.S loudspeaker produce the best sound.
The power amplifier of BL - 450A applies real Class I circuit design, which make sound production more accurate and loudspeaker effect better in the event of large power margin. The function of loudspeaker in a good audio system can never go unnoticed.
