x PCM (Pulse Code Modulation)

A method of converting analog audio to digital
audio for easy enjoyment of digital sound.

x Progressive

A scanning method that draws all scanning
lines sequentially, as opposed to interlaced
scanning where all the odd and then all the
even lines are drawn.

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

x S video signal

A format for transmitting video signal
information. S video uses a single cable and
two channels, one for the Luminance signal Y
and another for the chrominance signal C.
Better picture quality for recording and
playback than that of Composite signal is

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
The amount of energy used to measure signals
is important to ensure measurement accuracy
in a normal indoor environment. Using TSP
signals makes it possible to measure signals


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.

• The unit is not disconnected from the AC

power source (mains) as long as it is
connected to the wall outlet, even if the unit
itself has been turned off.

• 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.

On placement

• Place the receiver in a location with adequate

ventilation to prevent heat buildup and
prolong the life of the receiver.
