x S-AIR (Sony Audio Interactive
Radio frequency)
Recent times have seen the rapid spread of
DVD media, Digital Broadcasting, and other
high quality media.
To ensure that the subtle nuances of these high
quality media are transmitted with no
deterioration, Sony has developed a
technology called “S-AIR” for the radio
transmission of digital audio signals with no
compression, and has incorporated this
technology into the EZW-RT10/EZW-T100.
This technology transfers digital audio signals
with no compression using the 2.4 GHz band
range of ISM band (Industrial, Scientific, and
Medical band), such as wireless LANs and
Bluetooth applications.
x Sampling frequency
To convert analog audio to digital, analog data
should be quantified. This process is called
sampling, and the number of times per second
the analog data is quantified is called the
sampling frequency. A standard music CD
stores data quantified at 44,100 times per
second, which is expressed as a sampling
frequency of 44.1 kHz. Generally speaking, a
higher sampling frequency means better sound
quality.
x TSP (Time Stretched Pulse)
A TSP signal is a highly precise measuring
signal that utilizes impulse energy, measuring
a wide band, from low to high, in a short
period.
The amount of energy used to measure signals
is important to ensure measurement accuracy
in a normal indoor environment. Using TSP
signals make it possible to measure signals
effectively.
x x.v.Color
“x.v.Color” enables the more faithful
reproduction of various colors such as the
brilliant colors of flowers and the turquoise
blue of the southern ocean.
Precautions
On safety
Should any solid object or liquid fall into the
cabinet, unplug the receiver and have it
checked by qualified personnel before
operating it any further.
On power sources
• Before operating the receiver, check that the
operating voltage is identical with your local
power supply.
The operating voltage is indicated on the
nameplate on the back of the receiver.
• If you are not going to use the receiver for a
long time, be sure to disconnect the receiver
from the wall outlet. To disconnect the AC
power cord (mains lead), grasp the plug
itself; never pull the cord.
• One blade of the plug is wider than the other
for the purpose of safety and will fit into the
wall outlet only one way. If you are unable to
insert the plug fully into the outlet, contact
your dealer.
• The AC power cord (mains lead) must be
changed only at a qualified service shop.
On heat buildup
Although the receiver heats up during
operation, this is not a malfunction. If you
continuously use this receiver at a large
volume, the cabinet temperature of the top,
side and bottom rises considerably. To avoid
burning yourself, do not touch the cabinet.
