PCM (Pulse Code Modulation)
A method of converting analog audio to digital 
audio for easy enjoyment of digital sound.
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.
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.
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 
achieved.
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 makes it possible to measure signals 
effectively.
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.
• 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.
