Using Surround Sound
2Adjust the volume levels so that you hear the test tone from each speaker at the same volume level when you are in your listening position:
•To adjust the volume between the front right and front left speakers, use the BALANCE control on the front of the main unit.
•To adjust the level of center speaker, press CENTER LEVEL + or – on the remote.
•To adjust the level of rear speakers, press REAR LEVEL + or – on the remote.
3Press TEST TONE on the remote to turn off the test tone.
You can adjust all speakers at one time
Adjust MASTER VOL.
Adjusting the delay time
You can make the surround sound more effective by delaying the output from the rear speakers (delay time). You can adjust the delay time in 0.1 ms steps (for
1Start playing a program source encoded with Dolby surround sound.
2Press DPC MODE until the SURROUND indicator lights up.
3Rotate the PARAMETER knob to select the delay time.
The current delay time appears in the display.
4Rotate the LEVEL knob to adjust the delay time.
Adjusting the equalizer (STR-GA8ES) or tone (STR-GA7ES)
You can adjust the tone of the speakers.
Follow the procedure described in “Adjusting the equalizer” or “Adjusting the tone controls” on page 20.
Taking Advantage of the Sound Fields (STR-GA8ES)
This receiver uses digital signal processing to reproduce the sound effects of various listening environments, such as a movie theaters and concert halls (etc.). By adjusting the surround parameters you can control thes sound elements to create a custom listening environment.
Room Size Simulation (ROOM SIZE)
Before sound reaches our ears, it is reflected many times between the left and right walls, ceiling, and floor. In a large room, sound takes more time to bounce from one surface to another than in a smaller room.
The ROOM SIZE parameter lets you control the spacing of the early reflections to simulate a sonically larger (L), or smaller (S) room. The
Wall Material Simulation (WALL TYPE)
When sound is reflected off soft material, such as curtain, the high frequency elements are reduced. A hard wall is highly reflective and does not significantly affect the frequency response of the reflected sound. The WALL TYPE parameter lets you control the level of the high frequencies to alter the sonic character of your listening environment by simulating a softer (S), or harder (H) wall. The
Seat Position Simulation
(FRONT/REAR and LEFT/RIGHT)
If you sit in the front of a room, you hear more direct sound from the front speakers. As you move to the rear, the reflected sound increases. Similarly, the reflected sound changes when you move from left to right, and vice versa.
The FRONT/REAR and LEFT/RIGHT parameters let you control the balance of direct and reflected sound to simulate your listening position.
In the FRONT/REAR parameter, “F” signifies the front of the room and “R” signifies the rear. The
In the LEFT/RIGHT parameter, “L” signifies the left side of the room and “R” signifies the right side. The
