Ma series professional power amplifier; compact structure, strong comprehensive reliability, sweet sound is a power amplifier developed for high standard audio performance engineering, especially suitable for KTV entertainment, conference room, multi-functional hall, bar and other places. The power is supplied by high-grade powerful large ring bull transformer. Scientific and reasonable wiring layout, high efficiency, energy conservation, environmental protection and high integration circuit parallel design, very mature and stable power amplifier circuit and heat dissipation design, independent optional clipping limiter to reduce distortion and protect speakers. It not only makes bass more shocking, but also reduces heat consumption, improves reliability, reduces noise, and makes voice bright and elastic. All protection functions are complete, so that it can work easily in all kinds of environments. Can be configured as a variety of loads to meet the personalized and flexible configuration of various speaker models.
Feature applications:
◆ 2U body design
◆ with overheat, clipping, overcurrent, overvoltage, switch buffer protection, switch buffer protection, startup signal delay, short circuit protection
◆ ground separation switch
◆ working mode conversion (stereo, bridge and parallel mono)
