Serene is a preamplifier from HoloAudio. Serene adopts a fully balanced structure. The left and right channels completely separated form a fully balanced structure. Each channel has independent amplification modules to complete the buffering and amplification functions.
The design is able to solve the shortcomings of the transistors, so that its tone can exceed the limits of traditional transistors. It also has both the advantages of tubes and transistors. And the use of a large number of transistors makes the linearity of the amplifier superior in every way. The volume control of the Serene is a fully balanced stepping device controlled by a relay. IEach step is 1 db volume. The advantage is that the noise is minimal and small, and it can be precisely controlled, even at a low volume the left and right channel will not be biased.
Holo audio caps and a 7N O-type transformer as well as CNC Remote Control are included in the Level 1.
