SETUP AND TROUBLESHOOTING
4ESTINGTHE3YSTEM
After you have completed the installation, you need to test the
system. This will help ensure years of trouble-free operation. Please
refer to the listed steps below when testing the sound of your Orion
system.
1.
Check all the wiring connections to be sure they are correct and
secure.
2.
Turn the signal source volume control all the way down. Set any
tone controls to their flat or defeated positions. This includes the
loudness control.
3.
Turn the level controls of the amplifier to their minimum posi-
tions.
4.
Turn the source unit on. Check to see if the power LED located
on the top of the amplifier is on. If not, please refer to the Power
Connections and the Troubleshooting Tips sections of this manual
for instructions.
5.
If using an aftermarket source unit, turn the level controls of
the amplifier about one quarter of a turn. Slowly increase the
volume level of the source unit until you can hear the output of
the system. If no sound is heard or if the output is distorted, turn
the system off immediately. Refer to the Power Connections and
the Troubleshooting Tips sections of this manual to solve your
installation problems.
6.
Check to make sure the output for each channel is correct. If the
active crossovers are used, check to make sure that each output is

correct from the amplifier. When using active crossovers on mid-
range and tweeters, do not use crossover frequencies lower than
recommended. If the system is not configured properly, refer to
the Internal Crossover Configuration section of this manual and
take corrective action.
7.
If the output is clear and undistorted, continue to the Adjusting
the Sound of the System section of this manual.

Once you have checked the system's operation, adjust the sound of
the system. Adjusting the sound of the system is accomplished by set-

1.
Turn the signal source volume control all the way down. Set any
tone controls to their flat or defeated positions. This includes the
loudness control.
2.
Turn the level controls of the amplifier to their minimum posi-
tions.
3.
Choose music with high dynamic content that you like, with which
you are familiar, and will be used most often in the system.
4.
Turn the source unit's volume control up to its highest undis-
torted 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 distortion. 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.
5.
While listening to your chosen dynamic music, turn up the level
control corresponding to the midrange output until you hear
