— A 2.4GHz wireless multizone audio
system developed by MusicLites uses combination
LED-light/speakers that screw into
existing recessed-light fixtures in the ceiling.
The system can also be used in a single
zone to enhance TV sound.
The light speakers, as well as planned
matching LED lights without speakers, are
small enough to screw into 4-inch in-ceiling
cans as well as into 5- and 6-inch cans.
Trim rings are provided to hide any gaps. The
4- and 6-inch cans account for the majority of
the installed base of in-ceiling lights, the company
noted. All lights will be dimmable from a
home’s existing dimmers and via a remote.
With enhancements introduced since the system
was disclosed midyear, MusicLights systems will
use multiple transmitters to create up to a four-zone
multi-room audio system with an unlimited number of
speaker lights driven per transmitter. A light speaker
for table lamps is also in the works.
MusicLites founder Cary Christie said his system, marketed
under the MusicLights brand, will expand the multiroom
audio market to renters and to retrofit applications.
The company plans to demo off-toll models at the
show, where it will take orders for expected deliveries
sometime in November. Prices were to be disclosed
at CEDIA Expo this week.
Each in-ceiling light speaker operates as a left or right
speaker, and each incorporates a 2.75-inch full-range
driver in a sealed enclosure with effective response
from 50Hz to 20kHz making a subwoofer unnecessary,
Christie said. The driver is driven by a 20-watt Class D
amp with digital EQ and bass enhancement.
To supply music to the speakers, consumers could
connect up to four AC-powered wireless transmitters
into separate audio sources, whose music would be
transmitted up to 30 meters. Each transmitter would
stream only one source at a time.
In addition, music in a single room could be supplied
by an iPod Touch, iPad or iPhone connected to
a 30-pin wireless dongle, which incorporates embedded
rechargeable battery and whose output would
extend 10 meters.
A USB dongle for laptops, as well as a dongle that
connects to the 3.5mm analog headphone output of
an MP3 player or smartphone, could also be used to
deliver music to light speakers in a local room.
A credit-card IR remote aimed at a speaker would
control source selection, volume and light dimming
in a local zone. The local-zone functions could also
be controlled via RF wireless from a dongle-equipped
PC or iPhone/iPad.
