Testing the System

Set Up and Troubleshooting

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 connection side 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 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 instal- lation 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..

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 set- ting the level controls and adjusting the internal crossovers..

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
