CA-D200 200W TWO-CHANNEL AMPLIFIER
CA-D200 is a new and innovative amplifier design that uses what are called
switching technologies. Switching amplifiers and power supplies offer many
advantages but present different challenges and a higher degree of complexity
than conventional linear designs. Their potential is too great to ignore,
however, which is why the Classé Design team now includes engineers with over
fifty years combined experience in switching amplifier and power supply design.
The result is the CA-D200, the first of its type from Classé; the first of its
Switching Power Supply
A new Switch Mode Power Supply with Power Factor Correction, provides over
1,000W of clean, stable power to the CA-D200 amplifier circuitry. The SMPS and
PFC each operate at over 90% efficiency, yielding impressive benefits for power
delivery. The low frequency dynamics, extension and control of the CA-D200 and
its ability to effortlessly drive difficult speaker loads can be credited in
large part to the powerful and sophisticated power supply it employs. The SMPS
with PFC is ideally suited to the demands of the CA-D200’s revolutionary
switching amplifier topology.
Some technical limitations have been commonly accepted as inherent in switching
amplifiers—until now. Perhaps the biggest limitation is called dead-band time,
which translates directly to distortion and tempts designers to employ
excessive amounts of negative feedback to compensate. With its proprietary
drivers and DSP tools, the Classé Design team solves the dead-band time problem
with precision and consistency for each and every CA-D200. On power up,
controller circuitry analyzes and adjusts to minimize the dead-band time for
each pair of outputs. In this way, part tolerances and drift for each
individual amplifier are taken into account. Lastly, the feedback loop is
closed using the least amount of negative feedback required. Our linear phase
output filters are then employed only to filter the 384 kHz switching
frequency, not to roll off the top end of the audio band, as is often done to
try to make amplifiers with high dead-band time more listenable. The result is
a wide and deep soundstage with extended high frequencies that reveal a
musically detailed and open midrange and top end.
The CA-D200 employs proprietary component parts and DSP technology along with
sound engineering practice to optimize its sonic performance at an affordable
price of admission for a Classé amplifier. Listen and hear for yourself how
beautiful great value can sound.
