Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: The AW1 package includes a Sender (transmitter) and
Receiver; the system is designed to deliver an audio signal wirelessly between two
components. This system will work in many different applications, including (but
not limited to) a computer sending audio to powered speakers, a computer sending
audio to a stereo or A/V receiver, an iPod or other portable player sending audio
to the Audioengine A5 powered speakers (the A5 is specifically mentioned here
because it has a USB port to power the AW1 Receiver), and an A/V receiver sending
audio to powered surround or second zone speakers.
Sender: The AW1 Sender is powered through its USB plug; one
USB AC power adapter is included with the system to power either the Sender or
Receiver. If not powered by the included adapter, the Sender can be powered by
a computer, iPod power supply, or numerous other USB power supplies currently
available. The audio input is a 3.5mm stereo mini-jack. When used with a computer,
the Sender acts as a sound card and receives its audio input through the USB port,
so no connection to the mini-jack is necessary.
Receiver: The AW1 Receiver is powered through its USB plug;
one USB AC power adapter is included with the system to power either the Sender
or Receiver. If not powered by the included adapter, the Receiver can be powered
by Audioengine A5 powered speakers, an iPod power supply, or numerous other USB
power supplies currently available. The audio output is a 3.5mm stereo mini-jack;
no audio signal is transferred through the USB connection.
Pairing: The Sender and Receiver in this package are linked
together at the factory, so no pairing is necessary. If you have several AW1
systems, multiple Receivers can be paired with each Sender, and vice versa, but
each can only communicate with one of the other at a time.
Transmission: The AW1 transmits uncompressed PCM audio in
the 2.4 GHz range using a closed protocol specifically designed for audio. The
system avoids interference by constantly monitoring the entire 2.4 GHz spectrum
and choosing the channel that can achieve the cleanest transmission. The system
detects deteriorating conditions on the current channel and switches if needed
in under 20 ms, without any interruption in the audio stream. The AW1 also
employs dynamic transmit power control, meaning it transmits with only as much
power as required to maintain a clear audio connection. This makes AW1 coexist
better with other 2.4 GHz devices, including WLAN, Bluetooth, and other Audioengine
