FHSS (Frequency Hopping Spread Spectrum) Technology: The SoundCast
UAT is an interference free, wireless 2.4 GHz universal audio transmitter. The SoundCast
universal audio transmitter uses frequency hopping spread spectrum (FHSS) technology in which
the transmitter constantly and automatically searches for open channels in
the 2.4GHz band and jumps to them to avoid interference with other products
(such as cordless telephones, radio controlled toys, cell phones, microwave
ovens, remotes, and wireless routers), while telling your connected SoundCast
speaker system or receiver (sold separately) which frequency to use, and
ultimately send your connected source's audio signal wirelessly to your SoundCast
speaker system or receiver.
Note: To complete your AudioCast system, you will need a SoundCast
Receiver or a SoundCast wireless speaker system, such as the
iCast (all sold separately).
Wireless Range: The
SoundCast universal audio transmitter (UAT) has a range of 150' from your
SoundCast speaker system or receiver (sold separately). Outdoors, the signal may
carry up to 350' depending on conditions.
Note: The SoundCast UAT
is not weather-resistant and not designed to be placed outdoors.
USB Input: The SoundCast's
universal audio transmitter's mini-USB type-B port and supplied USB cable allows you
to turn your computer into a wireless music server. Once connected you can
wirelessly stream your computer's audio to any SoundCast speaker system or receiver
(sold separately). Your PC or
Mac will need to meet the following requirements to use this transmitter.
Requirements ||Mac System Requirements |
|Pentium 4 or later |
Windows XP or later
Available USB port
iTunes 4 or higher, Windows Media Player 9 or higher, Music match 9
or higher, RealPlayer 10 or higher
|PPC G3 or later, or Intel based Mac |
Mac OS 9.2 or Mac OS x 10.2 or later
Available USB port
iTunes 4 or higher
Note: If you have
both a computer and a component attached to the UAT, the USB computer
circuit will always take precedence. You will need to disconnect the
computer in order to transmit audio form a component.
Media Player Controls: The
SoundCast UAT allows you to control basic media player functions from
any SoundCast speaker or receiver (sold separately). Its USB audio structure
allows you to control basic functions of track forward, track back, pause/play
for commonly used media players through USB connection to a Mac or PC.
Note: The SoundCast UAT, itself, does not offer any controls. The
controls will be found on the SoundCast speaker system or receiver (sold
Analog Audio Inputs: The
universal audio transmitter's stereo RCA audio inputs allow you connect almost
any audio source so you can wirelessly transmit your music to any SoundCast
speaker system or receiver
Note: The UAT does not have an internal amplifier. Any speaker
system that are attached to this unit must have internal amplifiers in order
to play music.
Headphone Output: If you
wish to connect the SoundCast UAT to a set of headphones, you may do so by
inserting your headphone's plug into the 3.5mm headphone jack on back of the
Sensitivity Selector: The
SoundCast UAT has been set at the factory for the output voltage of most common
component devices. However, should you find the signal received by the SoundCast
receiver or speaker system (sold separately) is much lower in volume, there is a
sensitivity switch on the bottom of the unit to adjust the unit's overall gain.
Room Selector Switch: The
UAT has a multi-room and same-room selector switch on the bottom of the
transmitter. This will maximize the performance when you are transmitting music
in the same room, or from one room to another room in your house.
Multi-Room Compatible: The
SoundCast UAT can operate up to two SoundCast receiver or wireless speaker
systems. This means you can transmit audio to two different locations in your
home. You can also connect two UATs to the same audio source using the output of
one transmitter linked to the input of another transmitter. By linking the two
transmitters, and by using two SoundCast receivers or speaker systems for each
one, you can create a four zone audio system (the same music source will be
heard in all areas and you can only link a maximum of two transmitters). It is
also possible to operate two entirely different SoundCast systems in the same
Note: You will need to
make sure the UAT's channel selector switch and the receiver's channel
selector switch (in the same system) are set to the same channel (1-3).
Power Supply: The SoundCast universal audio transmitter
operates off of USB or AC power. The USB circuit in your computer will provide
power for the UAT. You can also plug the UAT in an AC wall outlet.
