1. VZ series power amplifiers use particular symmetrical floating circuit design. It can reduce the distortion and make better sounds, but the cost is higher.
2. With the power auto switch system, power parallel connection in low power increases the output current and decreases the output impedance. The voltage will automatically increases in high power so that the output power will be increased.
3. It has input power supply filter which makes the capability of anti-jamming stronger.
4. With the shield cover outside the amplifier circuit and adding shield rings in transformer, noise will be less and sounds will be clearer.
5. Independence closed cooling ventilation slot makes the cooling faster. It will still be clean even has been used for a long time.
6. VZ series amplifiers have perfect protect functions: power-on amortized, speaker connection delayed, amplitude limit function, over-current protection, over-heat protection, short circuit protection, output DC protection and so on.
