| EB-1102/216: EXTENSION BOARD. |
| The block schematic of the ALL-FET Extension board EB-1102/216 is shown in fig. 1. It contains two filter buffers, the same buffers as the ones on the EB-1102/215 board. Both filters can be configured as LP or HP filters, with 6, 12, and 18 dB slope. The filters can be cascaded for 24 dB/octave Linkwitz filters. |

| The extension board can be used together with the EB-1102/215 basic board to make 3-way and 4-way crossovers. It can also serve as an experimental board to work out the best combination of filters for your speaker |
