IMPORTANT: LISTENING AT HIGH VOLUME LEVELS CAN
CAUSE PERMANENT DAMAGE TO YOUR HEARING. BEFORE
USE, READ ALL WARNINGS AND INSTRUCTIONS.

gUidelines established by the U.S. Occupational Safety Health Administration
(OSHA) for maximum time exposure at various sound pressure levels. Ignoring
these guidelines can result
in permanent hearing loss. The following table may
prove helpful.
•90 dB SPL for 8hours
•95 dB SPL for 4hours
•100 dB SPL for 2hours
•105 dB SPL for 1hour
•110 dB SPL for 1/2 hour
•115 dB SPL for 15 minutes

A Beginner's Guide to Good Audio
What qualities distinguish agood audio system?
Let's start with amisconception. "Wow! I'll bet that can play loud!" This,
or something like
it, is typical of the newcomer's reaction to an audiophile's setup, particularly if the
speakers are large.
Why asystem's loudness capability should
be the measure of excellence isn't difficult to
understand. People install often quite costly sound systems
in their cars. Some of the
larger specimens seem capable
of shaking their host vehicle apart. The pavement
trembles when one passes by. Aclub's sound system is in the same league: ear-splitting,
gut-wrenching, floor-buckling output. With the exception
of classical music, which is rarely
ever amplified, the same is true for most live concerts. Domestically, the average boom
box can break alease. TV ads featuring hard-pumping woofer cones say it all.
On actually sitting down and listening to our hypothetical audiophile's sound system, the
newcomer will likely say "Wow!" again, followed this time by "It's so clear!"
Clarity. The term takes
in ahost of qualities. As strange as this may seem, one of
clarity's principal components is silence. Asilent audio system - an audio system that
contributes little to no noise
of its own -reveals the music all the more clearly at
listening levels from soft to loud.
Resolution likewise contributes to clarity. Imagine two mounds of sand in bright sunlight.
One mound
is mixed with mud. It's difficult to see its individual grains. The other mound is
free of mud. You have no trouble seeing its tiny, glittering bits. And so it is with high-
quality audio. The music shines through. Nothing muddies the sonic image. You hear the
texture
of asinger's voice almost as if she's in trte room. Instrumental timbres allow you
to distinguish the purposeful grunge of the rockers' gUitars. Violas differ from violins,

likewise oboes from English horns. Agood sound system allows you to make these
listening distinctions.
Soundstage. Another critically important measure of an audio system's quality is its
ability to project aconvincing soundstage. Can you perceive its width and depth? Is it
realistically proportioned? Can you hear the venue as large or small? Is it clear to you
where the musicians perform within the soundstage? Depending on the style
of recording,
our audiophile's sound system provides the answers. And
of course the pleasures.
Speed. An audio system's superior speed produces crisp, clean attacks: aviolin or
trumpet's edge, adrummer's rim shot, amarimba's wooden loveliness -all those little
delights that mimic live music.
Bass. To return to trembling pavements and hard-pumping woofer cones, the
audiophile's guest will be pleasantly surprised to discover that ahigh-quality sound
system's low end is as tuneful and clean as the rest
of the audio spectrum. Again, no
mud. Just lovely, well-defined sounds. Agood audio system aims at naturalness.
Size. Good audio is not necessarily big audio. If you shop wisely, you need not spend a
fortune to achieve ahigh level
of audio performance. With these pointers as aguide, the
newcomer has agood idea
of what to listen for. The least expensive NuForce
components will more than satisfy modest applications. With our reference-grade
components serving as the culmination of all our efforts,
our entire line answers to the
same ideal: accurate, vibrant, lifelike sound.

Using the Icon Mobile for the first time
Charge your Icon Mobile initially for at least 4hours. This conditions the Lithium battery to
afully-charged status and extends its useful life span. Subsequent battery charges, as
needed, should take about 2hours.
Functional descriptions
The Icon Mobile has no ON/OFF switch. The unit turns on when headphones are inserted
in any of its output jacks.
Controls
•Volume: Always turn the Icon Mobile's high-quality, analog volume control to
minimum before and after each use to prevent sound bursts that can damage your
hearing.
•Gain: Use the included plastic tool to access the Gain switch. Do not use apen or
screwdriver as these may damage the switch. High gain (+) is designed for use
with full-size headphones such as Sennheiser, AKG, etc. Low gain (-) is designed
for use with in-ear monitors such as Nuforce, Shure, Etyomotics, etc.
•USB connects to aPC for charging as well as for using the Icon Mobile as aUSB
sound device. The Icon Mobile works with Windows XP, SP2 or higher, including
Vista, as well as with Macintosh with USB 2.0 support. If a4-pin earphone set
(such as Nuforce NE-7M) is connected to the center 3.5mm 4-pin jack, Icon Mobile
is able to support internet phone or voice messaging features from Skype, MSN
or
other messaging software.
STATUS LEOs
•Power On: the blue LED Indicates that the Icon Mobile is powered on. There is no

On/Off switch. The Icon Mobile is turned on whenever an headphone plug is
inserted into any of the headphones outputs. The Icon Mobile turns off when the
headphone jacks are removed.
•USB: the white LED indicates that the USB connection has been established. The
white LED blinks when the USB port is transmitting USB data.
•EXT: the yellow LED indicates that an external line-level device has been plugged
into the input (e.g., an iPod). The external line-level device takes precedence over
the internal USB audio. The yellow LED blinks to indicate that the microphone input
is
in amute mode.
•Battery Status: when the dual-color LED shows red, the battery is low. Green
indicates that the battery is charging. During normal use, the dual-color LED is
inactive.
Connectors
•Both headphone
outputs can be used simultaneously. For example, one
output can drive ahigh-impedance, line-in device such as an Integrated amplifier
or active loudspeakers with compatible 3.5mm or RCA jacks via the correct
adapter cable.
•Headphone output with microphone input: the center 3.5mm 4-pin jack
supports a4-pin iPhone-style headset such as the Nuforce NE-7M, to be used, for
example, with Internet voice applications. The NuForce headset's push-button can
mute and disconnect Internet calls. For privacy protection, the Icon Mobile defaults
to Mute ifaheadset is inserted while the USB is actively connected. This
feature exists only with the iPhone-style push-button headset.
•External Line In connects to astandard 3.5mm output signal from an iPod or
similar portable device. Ifthe Icon Mobile is connected to aPC's external audio via
USB, the external 3.5mm input will take precedence over the USB audio.
