Adjusting the Sound of the System

Once you have checked the system's operation, adjust the sound of the system. Adjusting
the sound of the system is accomplished by setting the level controls and adjusting the
internal crossovers.

Step 1

Turn the signal source volume control all the way down. Set any tone con-
trols to their flat or defeated positions. This includes the loudness control.

Step 2

Turn the level controls of the amplifier to their minimum positions.

Step 3

Choose music with high dynamic content that you like, with which you are
familiar, and will be used most often in the system.

Step 4

Turn the source unit's volume control up to its highest undistorted output
level. If you lack test equipment, this point occurs between 3/4 to full volume
depending on the quality of your source unit. Listen for any audible distor-
tion. If any distortion is audible, reduce the volume of the source unit until
you have an undistorted output. Leave the volume control at this position
during your system tuning.

Step 5

While listening to your chosen dynamic music, turn up the level control cor-
responding to the midrange output until you hear slight distortion and turn
the level control back slightly for an undistorted output. Depending on your
system, the midrange and tweeter output may be on the same output chan-
nels.

Step 6

Turn up the level control corresponding to the tweeter output until you hear
slight distortion and turn back the level control slightly for an undistorted
output. Depending on your system the midrange and tweeter output may be
on the same output channels.

Step 7

Fine-tune the output level between midrange and tweeters. Refer to the
Internal Crossover Configuration section of this manual for detailed instruc-
tions.

Step 8

Repeat Steps 5-7 for the rear speakers. If you do not have rear speakers con-
tinue to Step 10.

Step 9

Set levels between the front and rear midrange and tweeters for optimum
front/rear balance.

Step 10

Turn up the level control corresponding to the woofer output until you hear
slight distortion and turn back the level control slightly for an undistorted
output.

Step 11

Fine-tune the output level between satellite speakers and the woofers. Refer
to the Internal Crossover Configuration section of this manual for detailed
instructions. If using an RGC-1, adjust the level to the output of the woofer
to match the sonic requirements of the system.

Step 12

Enjoy your awesome Orion sound system.
