Overview
“沧”Azure is a preamp/headphone amplifier from Holo Audio.
“沧”Azure adopts a fully balanced structure with 4 groups/channels. The
left and right channels form a fully balanced structure. Each channel has
two independent amplification modules to complete the buffering and
amplification functions.
There is a total of eight amplifier modules built into the “沧”Azure and
they are fully discrete. 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
quantity of transistors makes the linearity of the amplifier superior in every
way.
The volume control of “沧”Azure is a fully balanced stepping device
controlled by a relay. It has a total of 64 steps, and each 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.
“沧”Azure has three output modes, low-impedance headphone output
mode, high-impedance headphone output mode, and line output mode.
