April Music Stello S100 - Manual (Page 2)

INTRODUCTION
Thank you for choosing the Stello S100 Stereo Power Amplifier from April Music.
Stello S100 is a power amplifier with 50W of output in STEREO mode.
Stello S100 has a pair of power transistors. To ensure top musical performance and longer
life of operation, special circuits are applied which is unique for S100.
Stello S100 is a matching power for HP100 preamp/headphone amp.
Sized same as the other 100 series product line (HP100 & DA100), this Stello S100 is a
very interesting power which emits 50W per channel.
Even though the size of S100 is very compact, the driving power is far beyond your
imagination due to the special design concepts from April Music design team. The
musicality is just like or more than that of the bigger and more expensive power amplifiers
in the market.
The differences of this S100 and the other Stello 200 series power are that this one
supports only the unbalanced RCA connectors and the power is 50W + 50W.
When it matched with HP100 as a preamplifier, the HP100+S100 system shows the real
high-end sound under U$1,500. It can easily defeat the other integrated amps on the
market by revealing real high-end factors like imaging, depth, focus and the subtle nuance
of music reproduction.
This is very compact power and can be placed anywhere. On the desk, living room area, or
your study can be the best places for this S100 power.
It can even be hooked up with your PC directly as long as you can use your PC volume
control as a preamplifier.
The sound? You should be the judge how good the sound of S100.
50W+50W of power is still enough to drive the most of the home speakers.
Special circuitry of SEPP (Single-Ended Push-Pull) comprised of bipolar transistors is
adopted and the power for the full discrete driving stage is supplied by the isolated lines
