SET UP AND TROUBLESHOOTING
Testing the System
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.
Step 1 Check all the wiring connections to be sure they are correct and secure.
Step 2 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 3 Turn the level controls of the amplifier to their minimum positions.
Step 4 Turn the source unit on. Check to see if the power LED located on the con-
nection side of the amplifier is on. If not, please refer to the Power
Connections and the Troubleshooting Tips sections of this manual for instruc-
tions.
Step 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 to so that 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.
Step 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 midrange and tweeters, do not
use crossover frequencies lower than recommended. If the system is not con-
figured properly, refer to the Internal Crossover Configuration section of this
manual and take corrective action.
Step 7 If the output is clear and undistorted, continue to the Adjusting the Sound
of the System section of this manual.
