Exactly what I needed to be able to bring the amp back to life... will come back to this site the next time I need schematics.
;
Information was accurate and very helpful.
However the continuity made it a little difficult to follow from one page to the next.
 ;
Very very good as usual very trustable site. Perfect!!!!!!
;
The Service Manual received was helpful. Good copy of original document.. I recomend all of my friends about this technical page.
;
Perfect, complete manual, exactly what I needed. Recommended to everyone.
Power Amplifier APPLICATIONS � BPx MODELS
To the right are several application diagrams to help plan your subwoofer system installation. Figures 1 through 3 show how to configure the JBL Power Series subwoofer amplifiers (models BPx500.1, BPx1100.1 and BPx2200.1) for 2-channel, bridged-mono and parallel-mono operation �Setting the utput Mode� on page 6). O NOTE: For simplicity, Figures 1 through 3 do not show power, remote and input connections. NOTE: If the nominal impedance of your speaker system is close to 2 ohms, be prepared to try both bridged and parallel configurations to determine which performs better.
