This model uses import capacitor ,powerful and euphony!

(1) There are two ways of input: balanced input and unbalanced input and three modes
  can be chose: Stereo, MONO, bridgeable.
(2) With a delay circuit for relay, it can protect the speaker system, and adjust the shock
  wave when the produce is start-up.
(3) With dependable multiple protection: overload, over temperature, short circuit and delay
  of start-up.
(4) Using low noise temperature control fan, if the temperature is exceed the safe setting,
  this unit will shut down automatically until the temperature is back to normal.
(5) With high precision longevity potentiometer, it can control the output power accurately.
(6) With high efficiency capacitor for power filter, the capacitor and nonpolar capacitor are
  mport from.
(7) With Japanese high quality big power audio tube with Toshiba.
(8) The design of the frame in this produce can avoid all the mechanical interfere and electrical   interfere.
