“What we recognised when we looked at the audio
peripherals for USB speaker phones, is that they were
all targeted at travelling sales reps and were fairly small
and all USB-powered,” Root explained.
“With USB power you get something like fi ve volts
at 500 mA w

of those four watts and apply it to your processing so
there’s nothing there to drive the speakers. We did the
analysis on how much energy was coming out of those

“Our perspective was that you’d often have someone
on a cell phone who is remotely calling in and is hard
to hear to begin with and you wouldn’t have any juice
to put any gain on that sound.
Revolabs has developed its FLX UC 500 and 1000

hones with this in mind. The latest model,

did the company develop it to meet the needs of
videoconferencing?
“T
h
e
fi
rst step was to
d
esign a rea

spea
k
er
f
or t
h
e
speakerphone with a tweeter and a three-inch mid
sub,” Root ex
p
lained.
“T

jump out at you right away because you have the right
p
art to accentuate that

art of the fre

The mid-sub drives the lower frequencies and fi lls the
room. W

”
Root ex
p
lained that combining UC systems with the
traditional deskto
p

hone made sense for Revolabs’
custo

s.
“A lot of our early customers that are Fortune

anies that have ado

the conference rooms where they also have a phone
next to them,” he said.

they can make a phone call and they can be on a UC
call at the same time and the audio will mix.”
