DC Stereo
Power Amplifier SA-P30
Features:
Toroidal
power transformer for compact size and high output power
The large
capicty power supply is composed of a toroidal transformer with particularly
high efficiency and two 10,000 µF large-sized design capacitors. This exhibits
ample margin, and more than enough power is supplied for an effective output of
35 W + 35 W. this enables dynamic, high quality sound reproduction.
A wide-range
DC Amplifier that reproduces the original sound with faithfully
With this DC
Amplifier, no condensers are used within the load return loop since condensers
can cause a phase distortion
The system
can be upgraded to a 70 W monaural amplifier with just a flick of a switch.
A switch
makes a BTL connection turning this 35 W + 35 W stereo amplifier into a 70 W
monaural amplifier. If one more of this unit is added on in the future, the
system can be upgraded into a 70 W + 70 W power amplifier
Protection
Circuits
The
protection circuit employs a newly developed IC and a relay eliminates
"pop" noise produced when the power is switched on and off. Other
features protect the transistors from short-circcuits in the output and also
the speakers which are isolated when leakage of DC is detected in the output.
