Power Amplifier SF-2300/2400/2600

Description:

·Input mode:balanced input & unbalanced input,working mode:stereo,mono,bridge;
·Adopt relay delay circuir to cany out the soft start-up character,protect the loudspeaker from the shock of starting equiment
·Every model has the perfect protection in delay,oveloading,over heat
·Adopt low-noise fan to fall off heat in close quarter,when temperature raises to 105℃ ，it will cutdown output automaticaly to protect the amplifer
from damage, when temperatured rop down to 85℃,it will illrestore working automaticaly.
·Adopthigh-quality & long-life 40-step rotary potentiometer,accurately
control the output powr.
·Adopt newes grounding technology to make noise less
·Adopthigh capacity filtering condenser
·Adopthing-quality,annualr and low leak magnetic transformer.
·Adopthigh-quality audio high power efferent
Use the latest CAD software to design the PCB,itmake the circuit more stable(center deviation:2mV)
