Detailed Product Description

(1) There are two ways of input: balanced input and unbalanced input and three modes can be chosen: 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) Using an up-to-date grounding technology, it makes the noise is too low to hear
(7) With high efficiency capacitor for power filter, the capacitor and nonpolar capacitor
are import from the USA
(8) Using separate quadrate transformer in the front of this produce for power supply,
it keeps the power amplifier working steadily, and uses high quality powerful
annularity transformer in the tail
(9) With American high quality big power audio tube
(10) The design of the frame in this produce can avoid all the mechanical interfere
and electrical interfere
