– The board designed anti-protection, not because of a momentary negation power is positive

Negative and burned the power amplifier board components

– The new mute and standby control interface, user-friendly design, so that DIY hobbies

Can be more reasonable to install the application

-Power input and speaker output using high current terminal block, you can use more

Thick wire, to ensure high power demand

– Shielding large current inductance, to prevent interference between each other, but also better defense

Only external magnetic field interference

– Large radiator, to ensure that high-power output can be better dispersed chip generated

High temperature, to ensure performance at the same time, better protection chip life

– Genuine genuine Philips BC037 electrolytic capacitors, regardless of performance, sound quality

Fruit, workmanship and other non-cottage high imitation capacitance can be compared

– Adjustable voltage output, the original LM317 adjustable regulator independent output circuit can be
For the use of pre-class MP3 players and other products, external products when the first adjustment is good
