Product description
DA series amplifier is a professional switching power amplifier with high power, which is designed for large-scale tour shows. The power of this amplifier is supplied by PFC+SMPS universal voltage
plus a regulated power. The amplifier module adopts Class-D technology to perfectly match. Each channel has independently adjustable rated output power voltage, so that the amplifier can drive
speakers of different power levels very conveniently. This DA series is one of the benchmark products in the application of large-scale touring sound reinforcement system. The DA series has 6
power levels and is suitable for large-scale performances, venues, commercial high-end entertainment clubs and other places. It is the first choice in audio engineering!
International standard 1U/44MM height design.
Using Class-D power amplifier module design from high-efficiency American IXYS field effect tube.
PFC+SMPS-Universal voltage + regulated power supply.
Adopting the most advanced audio-grade electronic components devices, new discrete component plug-in + SMD chip process design.
The rear panel VCL has independently adjustable rated output power voltage, and each model can adjust 4 kinds of power.
The connection mode of the rear panel selects stereo/parallel connection.
The whole device has intelligent all-round protection functions.
XLR female input/male output signal connection socket.
