Introduction of the Passive Preamplifier
Our company thanks you for purchasing the Passive Preamplifier, PPA –
01. Our PPA-001 is of a high quality range and a reakthrough in the
design of passive pre-amplifiers. Its performance can satisfy all music
lovers. Please e informed of its key features elow.

In electromagnetics, when an external magnetic field is applied to a
ferromagnet (e.g. iron), and the atomic dipoles align themselves with
it, a physics phenomenon called Magnetic Hysteresis occurs. In such
a case, even when that external magnetic field is removed, part of the
alignment retains. As a result, that ferromagnet material ecomes
magnetized.
Magnetic Hysteresis theory is also applied in our PPA – 01 design, y
winding coil around the transformer core. When current/voltage
passes through the coil, magnetic force is induced throughout our 59
steps autotransformer (C Core), a slightly delay effect on the sound
quality will result. This makes the transformer volume very different.
That explains why tu e amplifier usually produce sound quality
superior to that of solid-state amplifier.
With x, 3x, 5x and 0x gain options, this PPA - 01 provides the
following high uilt quality of sound:
