Introduction

Thank you for choosing the LX4-2.1 Studiophile Series 2.1 / 5.1 studio nearfield
monitor speakers. M-Audio is well known for digital audio interface technology,
digital converters, audio preamps and mixers. Now, after extensive research and
development, the Studiophile LX4-2.1 is born to change the concept of studio
reference monitoring in 2.1 / 5.1 systems.

The LX4-2.1 was designed and tested by veteran audio engineers to meet your
needs in a studio monitoring environment. It is focused on the functional goal of
delivering pure, original sound without any additional coloration. The LX4-2.1
monitor is self-powered from amplifiers contained in the Subwoofer enclosure,
which directly accepts a line level signal from a variety of sources.

The Subwoofer of LX4-2.1 provides extended low frequency down to 40Hz,
making it possible for LX4 system to be comprised of much smaller Left, Right,
and Surround satellite speakers, offering highly accurate frequency response
from 40 to 20KHz and ultimate convenience for desktop music production.

LX4-2.1 is designed with option to add the LX4-3.0 package, upgrading the
LX4-2.1 into a 5.1 system for music production or playback of 5.1 music and
sound tracks. This feature makes the LX4 system extremely flexible, fitting into
all modern digital music production and playback applications.

The Studiophile LX4 is designed to overcome the size limitations of conventional
studio reference monitors within the digital audio environment. This compact
system delivers a wide range frequency response by employing two
extraordinary drivers and unique crossover and equalization technology licensed
by M-Audio. Both drivers are magnetically shielded for desktop music production.

From pro engineers at commercial studios to home studio owners, the
Studiophile LX4 sets a new affordable standard in studio monitoring.
