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.
8.Repeat Steps
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.
12.Enjoy your awesome Polk Audio PA D Series amplifier..

|
| |
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.. |
