Tip
In addition to outputting the test tone, you can also
adjust the level of each speaker while listening to the
sound of a CD or DVD, etc. Although you lay the
foundation for high quality surround sound by
matching the levels of all speakers using the test tone,
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 playback 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.
Checking the connections
After connecting all of your components to the
amplifier, do the following to verify that the
connections were made correctly.
