Center mode
Setting of speakers to enhance Dolby Pro Logic Surround mode. To obtain the best possible surround sound, select one of the following four center modes according to your speaker system.
•NORMAL mode
Select NORMAL mode if you have front and surround speakers and a small center speaker. Since a small speaker cannot produce enough bass, the bass sound of the center channel is output from the front speakers.

Delay time
Time lag between the surround sound output from front speakers and surround speakers. By adjusting the delay time of the surround speakers, you can obtain the feeling of presence. Make the delay time longer when you have placed the surround speakers in a small room or close to your listening position, and make it shorter when you have placed them in a large room or apart from your listening position.
Direct tuning
Tuning method to let you directly enter a station’s frequency using the numeric buttons on the remote. Use this method if you know the frequency of the station you want.
Dolby Pro Logic Surround
As one method of decoding Dolby Surround, Dolby Pro Logic Surround produces four channels from two channel sound. Compared with the former Dolby Surround system, Dolby Pro Logic Surround reproduces

Preset station
A radio broadcasting station that is stored in memory of the receiver. Once you “preset” stations, you no longer have to tune in the stations. Each preset station is assigned its own preset number, which lets you tune them in quickly.
Surround sound
Sound that consists of three elements: direct sound, early reflected sound (early reflections) and reverberative sound (reverberation). The acoustics where you hear the sound affect the way these three sound elements are heard. These sound elements are combined in such a way that you can actually feel the size and the type of a concert hall.
