D•500 Mk II Class D Monoblock Amplifier
The D•500 is the first of new
MKII line of products. This second generation amplifier
builds on the heritage of the Award winning D•100 and D•200
models.
Over 2 years of development have gone into this project to
produce the best Class D audio amplifier available. This
compact & energy efficient package produces over 500
watts and will drive most any loudspeaker with authority,
musicality, and control.
The monaural design is housed in a beautiful new machined
aluminium chassis with heavy steel frame plate to support
the massive power transformer. Non-magnetic stainless steel
hardware and highest quality parts are used throughout.
SmoothStart™ and XDC•2 circuits control AC power, while our
DC board supplies the various output voltages required by
the audio circuit. Signal input is handled by panel-mounted
jacks for both single-ended RCA and balanced XLR
connections. Turn-on is accomplished by the front-panel
mute/play button, or remote 12v trigger (when used with
PLC•1 MKII or other makes with this function). Adjustable
5-way binding posts are used for loudspeaker connection and
can be configured for horizontal or vertical cable entry.
The audio circuit consists of an advanced full bridge UcD
design for life-like music reproduction and offers
unsurpassed performance, reliability, and efficiency. Due
to the large heat-sink area and high efficiency, D•500
remains cool to the touch even at continuous high output
levels. Protection from over-voltage and short-circuit
conditions are provided.
Many manufacturers have
introduced Class D designs but all have had their
shortcomings, whether it be sound quality, safety,
excessive EMI/RFI, or reliability. Due to new technology
and careful design, we are now able to offer a product
which realizes the full potential of switching amplifiers.
