Here to bring you commercial-free music, sports, and news listening in a
wealth of genre-based satellite streams is the Audiovox SIR-PNP2 Sirius
radio receiver. Use of the receiver requires activation of a
subscription to Sirius Satellite Radio ($12.95 per month or a one-time
fee of $499.99). You'll also need a portable, home, or car docking
apparatus. The receiver pulls in the signal, while a docking station
provides traditional features like speakers, headphone jacks, and
antennas, depending on the accessory. The receiver will produce no audio
without an ancillary listening device. We tested the receiver in 2 different systems: the Audiovox SIR-BB1
Sirius satellite radio portable boombox and the Audiovox SIR-CK1 sirius
satellite radio shuttle car kit. Using the receiver under different
circumstances--both stationary and mobile--gave a rounded portrait of
both the Sirius service and the performance of this particular receiver.
As a paid alternative to traditional FM and AM radio, the Sirius service
definitely has its benefits. Tons of stations and no commercials--it's
hard to beat that. With Sirius, great music is always easy to find.
With traditional radio, the audio signals ride "carrier frequencies"
(modulated waves of air) that a receiver subtracts before rendering a
wave as audio. With digital radio, frequencies carry data rather than
audio. A receiver simply performs the step of turning the numeric
transmission back to audio, much as the decoder chips and analog stage
of a CD player turns its digital data into sound. This means you'll hear
no static, fuzz, or spurious background noises from Sirius radio. The
end result is clear and clean. It also means, however, that when
reception gets hazy your audio program mutes briefly rather than getting
fuzzy or slightly more distant-sounding. This can prove disconcerting or
downright irritating if you're not listening in an area with perfect
reception.
When you're not moving, reception tends to be better, though still
potentially imperfect, depending on the location of Sirius' satellites.
(Owners of digital cable or satellite television will know exactly what
they're in for.) But by and large our stationary testing proved seamless,
letting us enjoy the many stations included in the Sirius package.
Setup and operation of the receiver is a breeze. There are 30 channel
presets (a group of 10 buttons with selectable A, B, and C bands) and an
intuitive scroll wheel with push selection for menu navigation.
Lovers of pop and rock music fare the best, but there's a little
something for everyone. If you're starved for underplayed classic rock,
you'll revel in a channel known as The Vault ("deeper classic rock"),
and '80s fans can take their pick of Big '80s, Hair Nation, and First
Wave ("classic alternative"). Parents and kids--we checked--will relish
the Sirius children's channel, especially in the car.
Unexpectedly rich are the news offerings, which include everything
from the major cable TV networks to radio staples like NPR and the BBC,
as well as 7 sports networks and a host of "entertainment" channels
(including Court TV). The lion's share of the channels in the
dance/electronica group falls to the dance category, leaving it to the
lone Chill station to weave a blend of electronica and other hip but
mellow (i.e., nondanceable) music. There are only 3 classical-music
channels, and for those with short attention spans one of them plays
movements of larger works rather than complete pieces straight through.
Beyond the reception issue, the only other major drawback is sound
quality, which some may find subpar. Sirius describes its sound as
"digital quality," a euphemism for "digital audio with a bitrate so low
that we don't want to scare people by revealing what it is." Whatever it
is, its character is very close to what you'd hear from 96 kbps
MP3--clear and listenable, but lacking depth, fullness, high-frequency
extension, and dynamic range (though radio's always been super
compressed). Your awareness of these shortcomings will depend to some
degree on the caliber of your playback system. We noted that the
classical stations seem to have better sound than the rock/pop stations.
Overall, we found the sound quality to be better than AM radio, nearly
or equally as good as analog FM stations, but worse than 128 kbps MP3
and inferior to high-quality analog cassette tapes (though there's no
tape hiss with Sirius). But for broadcast music programming, the Sirius
lineup is hard to beat and nothing short of a joy to listen to. For
