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.
