Polk Audio PA D1000.1 PA D1000.1 Owner's Manual - Page 6

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. Troubleshooting Tips Symptom No output Probable Cause Low or no remote turn-on. Fuse blown. Power wires not connected. Audio input not connected. Speaker wires not connected. Speakers are blown. Audio cycles on and off Thermal protection engages when amplifier heat sink temperature exceeds 85° C (185° F). Loose or poor audio input. Loose power connections. Distorted output Amplifier level sensitivity set too high exceeding maximum capability of amplifier. Impedance load to amplifier too low. Shorted speaker wires. Speaker not connected to amplifier properly. Action To Take Check remote turn-on at amplifier and repair as needed. Check power wire's integrity and check for speaker shorts. Fix as needed and replace fuse. Check power wire and ground connections and repair or replace as needed. Check line level connections and repair or replace as needed. Check speaker wires and repair or replace as needed. Check system with known working speaker and repair or replace speakers as needed. Make sure there is proper ventilation for amplifier and improve ventilation as needed. Check line level connections and repair or replace as needed. Check power wires and ground connections and repair or replace as needed. Readjust gain. Refer to the Adjusting the Sound of the System section of this manual. Check speaker impedance load if below 1 Ohm, rewire speakers to achieve higher impedance. Check speaker wires and repair or replace as needed. Check speaker wires and repair or replace as needed. Troubleshooting Tips Symptom Probable Cause Action To Take Distorted output Internal crossover not set properly for speakers Speakers are blown Readjust crossovers. Refer to the Amplifier Settings section of this manual for detailed instructions. Check system with known working speakers and fix or replace as needed. Poor bass response Speakers wired with wrong polarity causing cancellation at low frequencies. Crossover set incorrectly. Impedance load at amplifier is too low. Battery fuse blowing Check speaker polarity and fix as needed. Reset crossovers. Refer to the Line Level Input/Output/Control section of this manual. Check speaker impedance load if below 1 Ohm, rewire speakers to achieve higher impedance. Short in power wire or incorrect wiring. Check power wires and ground connections and repair or replace as needed. Fuse used is smaller than recommended. Replace with proper fuse size. Actual current exceeds fuse rating. Amplifier fuse blowing Check speaker impedance load if below 1 Ohm, rewire speakers to achieve higher impedance. Fuse used is smaller than recommended. Replace with proper fuse size. Impedance load at amplifier is too low. Check speaker impedance load if below 1 Ohm, rewire speakers to achieve higher impedance. Speaker is blown with shorted outputs. Check system with known working speakers and fix or replace as needed. Actual current exceeds fuse rating. Check speaker impedance load if below 1 Ohm, rewire speakers to achieve higher impedance. 10 © 2011 Polk Audio-all rights reserved © 2011 Polk Audio-all rights reserved 11
