A whole new Experience of Performance
A MUST Hi-Fi accessories for Audiophile
Trust your own ears to judge the quality of the sound
The linear power supply replaces the switching power supply configured for all kinds of digital audio, and the effect that comes out, I believe players who have used or experienced line power supply know well that the improvement is not a little bit.
As the level and price of digital audio products are getting higher and higher, the lack of security protection in traditional line power has also been significantly amplified.
The 2020 benchmark series linear power supply is designed by listening to the feedback of players and combining the actual situation in the process of designing and selling linear power supply by the zero-zone team for many years;
The main highlights of the smart version:
Large current in small size
Low noise, low resistance, large dynamic
Low noise: within the rated working current (within 4A), 20Hz-20KHz (audio range) ripple is only 1uV, only 4.8mV peak measured at 1MHz;
Low impedance: The newly designed linear voltage regulator module cooperates with Schottky rectifier, 46-bit capacitor array, and a transformer with the largest possible power in the chassis space to further reduce the internal resistance of the power supply
Big dynamics: Thanks to the low-impedance configuration: low-impedance linear voltage regulator module + high-power transformer + capacitor array, the response to the power supply energy output is extremely fast.
With overvoltage, overcurrent, short circuit protection
In the application of linear power supply, a very important protection method is over-voltage protection. Over-voltage is the original culprit of equipment damage, and there is no one; one more guarantee is more worry-free. Not to mention there are three kinds of protection!
Voltage regulator
It still continues the traditional zero-zone MOS Transistors in parallel, which has a positive effect on anti-excitation and rich harmonics.
School sound
The benchmark series linear power supply still follows the ZERO-ZONE sound calibration manual
"Price, performance and sense of hearing are equal, and the overall pursuit of harmony"
