SANTA ANA, Calif.--(Business Wire)--Feb. 14, 2001--
Microsemi Corp. (Nasdaq:MSCC - news) today announced that it has received
production orders for its new Class D Audio Amplifier IC from Benwin,
the brand fast becoming recognized for its cutting-edge multimedia
products.

The order for Microsemi's LX1710 mono class D audio IC are to be
used on Benwin's award-winning line of flat panel speaker systems.

Introduced in August of 2000, the LX1710 is a Class D Audio IC
having superior THD and signal-to-noise specs to its predecessor, the
LX1720 -- a popular device for use in efficient wireless speaker
systems. At 10 Watts, the LX1710 measures THD+N levels of 0.06% and an
SNR of 81dBV for its single channel controller. Two versions of the IC
are available, one for high power, and one for high fidelity.

``Our high efficiency is what attracted the Benwin group to our
product technology. The consumer attraction to their flat speaker
technology cannot be compromised by Audio amplifiers that require
bulky heat sinks,'' commented Roger Holliday, vice president of product
development for the Audio IC group.

``We are confident that combining our innovative IC technology and
the Benwin proprietary flat speaker technology is an ideal fit to
serving the multimedia audio market where space and power consumption
are becoming increasingly important -- this is indeed a marriage of
two state-of-the-art products.''

Benwin developed the world's first flat panel multimedia speaker
system by applying advanced engineering along with cutting-edge laser
technology and modeling. Their first flat panel speaker system
introduced in 1997 broke every rule in loudspeaker design, reaching
new heights of audio performance once thought impossible.

In commenting on the initial production order, Jim Vatrt,
president and CEO of Benwin stated, ``The applications for our
innovative flat panel speaker technology can be greatly improved by
teaming with industry leaders like Microsemi to develop
high-performance multimedia audio solutions.''

Future Product Development

Microsemi is currently expanding upon its successful development
of high power Class D Audio Circuits like the LX1710 and its ultra low
power 16 bit Class D Hearing Aid chips to develop energy efficient
Digital Audio amplifier ICs for mobile handsets and PDAs.
