Taking Advantage Of The Sound Fields - Sony TA-VA8ES Operating Instructions Manual

Using Surround Sound
2
Adjust 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 centre speaker, press
CENTER LEVEL + or – on the remote.
• To adjust the level of rear speakers, press
REAR LEVEL + or – on the remote.
3
Press 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
within the range of 15 to 30 ms. For example, if you've
placed the rear speakers in a large room or apart from
your listening position, set the delay time shorter.
1

Taking Advantage of the
Sound Fields
This amplifer uses digital signal processing to
reproduce the sound effects of various listening
environments, such as a movie theatres and concert
halls (etc.). By adjusting the surround parameters you
can control these sound elements to create a custom
listening environment.
Room Size Simulation
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 mid-point
designates a standard room with no adjustment.
Wall Material Simulation
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 mid-point designates a neutral
wall (made of wood).
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 mid-point
designates the centre.
In the LEFT/RIGHT parameter, "L" signifies the left
side of the room and "R" signifies the right side. The
mid-point designates the centre.
