Troubleshooting Tips - Polk Audio PA D1000.1 Manual De Instrucciones

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 .
7. Fine-tune the output level between midrange and tweeters . Refer to the Line Level
Inputs/Outputs/Controls section of this manual for detailed instructions .
8. Repeat Steps 5-7 for the rear speakers . If you do not have rear speakers continue to Step 10 .
9. Set levels between the front and rear midrange and tweeters for optimum front/rear balance .
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 .
11. Fine-tune the output level between satellite speakers and the woofers . Refer to the Line Level
Inputs/Outputs/Controls section of this manual for controls . Adjust the level to the bass output
of the woofer to match the sonic requirements of the system .
12. Enjoy your awesome Polk Audio PA D Series amplifier .
