Introduction:

Electricity is the mother of sound, and power quality plays a decisive role in the quality of audio/digital products. ZERO-ZONE is one of the few professional design and production linear power supply teams in the world. ZERO-ZONE has always been aiming at "price, performance and listening, and overall pursuit of harmony".

 

LPS-Leo is the first linear power version of ZERO-ZONE named after the constellation, At the same time, it is also divided into flagship level on the product line. The series pays special attention to the fine sound and equipment safety.

 

LPS-Leo linear power supply (flagship version), the design concept is mainly based on the pursuit of ripple, the pursuit of hearing,Give up power utilization.

 

This linear power supply is basically a low-efficiency and high-heat type. Some voltage parameters can be less than 50% efficient. It is similar to pure Class A power amplifier. There is no good sound without heat.

 

LPS-Leo pays attention to the neutrality and tastelessness in the school sound, and strengthens the extension of high and low frequency, and further strengthens the dynamic response. For players with higher system balance and players who like symphony, LPS- Leo is a very good choice.

 

In terms of safety, the LPS-Leo linear power supply incorporates the original high-sensitivity overvoltage protection device (V1.0) to protect your expensive interface, decoding, Phono amplifier and other HIFI products. Among the linear power supply protection devices, the most practical value is overpressure protection. Only overpressure protection is the real protection of your expensive equipment. When the LPS-Leo setting voltage exceeds 0.4V, it is protected.

 

The ripple noise at the audio frequency (20-20KHZ) is only a single digit UV. The LPS-Leo linear power supply provides a safe 3A continuous current output.

Tips: The output current will be determined based on the power of your transformer, and the higher the power, the greater the current. When using high-power transformers, please pay attention to strengthening the heat dissipation heat sink.
