x Dolby Surround (Dolby Pro 

Audio processing technology developed by 
Dolby Laboratories, Inc. Center and mono 
surround information is matrixed into two 
stereo channels. When reproduced, audio is 
decoded and output in 4 channel surround 
sound. This is the most common audio 
processing method for DVD video.

x DTS Digital Surround

Digital audio encoding/decoding technology 
for theaters developed by DTS, Inc. It 
compresses audio less than Dolby Digital, 
delivering a higher quality sound 
reproduction.

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.

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.

• 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, grasp the plug itself; never pull 
the cord.

• The AC power cord must be changed only at 

a qualified service shop.

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.
