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 .

Symptom Probable Cause Action To Take
No output
Low or no remote turn-on . Check remote turn-on at amplifier and repair as needed .
Fuse blown . Check power wire’s integrity and check for
speaker shorts . Fix as needed and replace fuse .
Power wires not connected . Check power wire and ground connections
and repair or replace as needed .
Audio input not connected . Check line level connections and repair
or replace as needed .
Speaker wires not connected . Check speaker wires and repair or replace as needed .
Speakers are blown . Check system with known working speaker
and repair or replace speakers as needed .
Audio cycles on and off
Thermal protection engages when
amplifier heat sink temperature
exceeds 85° C (185° F) . Make sure there is proper ventilation for
amplifier and improve ventilation as needed .
Loose or poor audio input . Check line level connections and repair
or replace as needed .
Loose power connections . Check power wires and ground connections
and repair or replace as needed .
distorted output
Amplifier level sensitivity set
too high exceeding maximum
capability of amplifier . Readjust gain . Refer to the Adjusting the Sound
of the System section of this manual .
Impedance load to amplifier too low . Check speaker impedance load if below 1 Ohm,
rewire speakers to achieve higher impedance .
Shorted speaker wires . Check speaker wires and repair or replace as needed .
Speaker not connected
to amplifier properly . Check speaker wires and repair or replace as needed .
distorted output
Internal crossover not
set properly for speakers Readjust crossovers . Refer to the Amplifier Settings
section of this manual for detailed instructions .
Speakers are blown 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 . Check speaker polarity and fix as needed .
Crossover set incorrectly . Reset crossovers . Refer to the Line Level
Input/Output/Control section of this manual .
Impedance load at amplifier is too low . Check speaker impedance load if below 1 Ohm,
rewire speakers to achieve higher impedance .
Battery fuse blowing
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 . Check speaker impedance load if below 1 Ohm,
rewire speakers to achieve higher impedance .
Amplifier fuse blowing
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 .
