VA SERIES
Product introduction
*The VA series is a high-performance power amplifier designed for high demand engineering. Adopting the production technology of black oil double-sided circuit design, the circuit is simple and practical, with excellent selection of components and a tunnel style radiator,Excellent protection function.
*It has multiple protection functions such as power soft start and intelligent short circuit protection. It has a wide voltage range and can operate normally even under a power supply voltage of 150V.
*The VA series adopts the classic low distortion switch H-class circuit, mainly aimed at pursuing high-quality sound quality of full frequency speakers, achieving rich high-level sense, transparent sound, wide and noise free bass, and bright mid frequency.
*VA series high-power can be paired with you, and the entire series of 2U chassis design reduces the fatigue you bring during transportation
*The dust-proof net on the panel can be removed and cleaned with cotton by twisting the screws by hand, which is easy to maintain and has a longer lifespan.
