  B series power amplifiers have excellent functions and timbre. Even if in very bad condition, it also works well. All these make it being your faith worthy 'friend'. low noise, low distortion, quick cooling and high reliability, the B series power amplifiers are your best choice.

 Features: 

  (1)、Balanced & unbalanced input, 3 work mode:stereo, single channel and bridge

  (2)、All have protection for delay, over loading, over heat, shout circuit

  (3)、Adopt low-noise fan to fall off heat, when temperature raises to 85℃ , it will cut down output automatic to protect the amplifier from damage; when temperature drop down 50℃, it will re-work automatic.

  (4)、One channel output supply for recording extend, and connect to other amplifier

  (5)、Adopt high-precision & long-life 40-step rotary potentiometer,accurately control the output power

  (6)、Adopt newest grounding technology to make noise less

  (7)、Adopt high capacity filtering condenser

  (8)、Adopt high-quality, annular and low leak magnetic transformer

  (9)、Adopt high-quality audio high power efferent

  (10)、Use the newest CAD to design the PCB, it makes the circuit more stable (deviation:≤2mV)
