Before You Use Your Receiver - Sony STR-DE475 Operating Instructions Manual

Notes
• The front balance, surround balance, center level, and surround
level are shown in the display during adjustment.
• Although these adjustments can also be made via the front
panel using the LEVEL menu (when the test tone is output, the
receiver switches to the LEVEL menu automatically), we
recommend you follow the procedure previously described in
this section and adjust the speaker levels from your listening
position using the remote control.
z
When setting the volume levels for each speaker
Let's assume that you have matched the sound levels of all the
speakers using the test tone. Although this lays the foundation
for high quality surround sound, it may be necessary to make
further adjustments while listening to playback of actual
software. This is because most software contains center and
surround channels recorded at slightly lower levels than the two
front channels.
When you actually play back software recorded in multi channel
surround, you will notice that increasing the center and surround
speaker levels produces a better blend between the front and
center speakers and greater cohesion between the front and
surround speakers. Increasing the level of the center speaker
about 1 dB, and the surround speakers about 1~2 dB is likely to
produce better results.
In other words, in order to create a more cohesive soundstage
with balanced dialog, we recommend that you make some
adjustments while playing your software. Changes of only 1 dB
can make a huge difference in the character of the soundstage.
