Advanced Analog Feedback

The 352.8kHz carrier signal is removed by the
fc 30kHz output LC filter, and forwarded
negative feedback is added to achieve
amplification over a wide bandwidth of 100kHz
and with a high damping factor (over 200),
without load impedance dependency.

Active Power Control System

This system detects the output current to
control the voltage limiter value in order to
independently control the continuous
maximum output and dynamic power, making
it possible to continually provide maximum
performance.

Monaural Independent Construction

Separate chambers provide higher efficiency and
ensure that there is no chance of electronic
interference degrading performance.

Power Engine Chipset

To overcome the limitations of
conventional digital amplifiers, Yamaha
developed its own Power Engine chipset,
which enables the MX-D1 to achieve high
levels of sound
quality and power,
as well as low power
consumption and
compact size.

Constant Gain PLL Modulator Circuit

This circuit eliminates the dependency of
the output signal on power voltage
fluctuation by using the YDA133
modulator LSI, which combines a PLL
circuit with a modulator circuit.

Cross Feedback Loop Circuit

The digital pulse output is fed back by the
Cross Feedback Loop, improving the
linearity of the output stage and of the
modulator circuit. This achieves superior
low distortion characteristics and high
dynamic range.

MX-D1

Stereo Digital Power Amplifier

Anyone familiar with the Yamaha name knows that we have always been dedicated to providing “natural
sound” in its truest sense — audio reproduction that sounds as close as possible to the real thing. Given our
success with other digital products and having the most advanced digital technology at hand, our engineers
decided to focus on creating a truly superb digital amplifier — one that would utilize the benefits of digital
technology without its drawbacks to deliver incredibly accurate and pure natural sound. The result is the
MX-D1. Prepare to be amazed and delighted.

x 2-15/16” x 10-5/16” (W x H x D) • 7.5 lbs.

The YPC-1, a Passive Controller unit,
provides input selection and volume control.
With a black finish that matches the MX-D1,
this unit is available as an option.

Custom Installation Compatibility

Using the MX-D1 in a custom installation is facilitated by its RS-232C interface for bi-directional control, ID
setting for a multi-channel amplifier system and trigger in/out daisy chain connection for synchronized power
switching via Through and Power modes.
