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 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

(2 Ohms, 4 Ohms min bridged); 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

(2 Ohms, 4 Ohms min bridged); 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

(2 Ohms, 4 Ohms min bridged); 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

(2 Ohms, 4 Ohms min bridged); 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

(2 Ohms, 4 Ohms min bridged); rewire

speakers to achieve higher impedance.
