Power Amplifier B3000A

Description:

·Balance & unbalance input, 3 work mode: stereo, single channel and bridge
·All have protection for delay, over loading, over temperature, short circuit
·Adopt low-noise fan to fall off heat, when temperature raises to 85℃, it will
·cut down output automatically to protect the amplifier from damage; when
·temperature drop down 50℃, it will re-work automatically
·One channel output supply for recording extend, and connect to other amplifier
·Adopt high-precision & long-life 40-step rotary potentiometer
·Adopt newest grounding technology to make noise less
·Adopt high capacity filtering condenser
·Adopt high-quality, annular and low leak magneti
·transformer
·Adopt high-quality, audio high power efferent Use the newest CAD to design the PCB, it make
the circuit more stable(center deviation:≤2mV)
