STAMFORD, CONN. —
Harman International has begun
shipping a hand-held device that uses digital signal
processing (DSP) to enhance the
sound quality and imaging of music
played through an existing car audio
system from any MP3 player, portable
media player, or smartphone.
The $239-suggested JBL MS-
2, which requires no installation,
plugs into a car radio’s aux input
and to the 3.5mm headphone output
of a portable device. It uses
digital equalization to automatically compensate for
the sonic characteristics of a particular vehicle’s car
audio system and for a particular vehicle’s acoustics.
Once connected, users press the setup button to automatically
tune the output of each
speaker. The device also features
bass, treble, impact and image controls
to allow for fine tuning.
The portable device weighs 3.2
ounces and fits into a pocket.
The device can also be used with
home audio systems if it’s powered
by a 6-volt DC power supply.
