You will need to set the dip switches for both right and left channel. Note: Only one dip switch per dip switch cluster should be on at a time.

5If available, use test equipment to optimize the sub- woofer response.

6The 50Hz control works the same as the 25Hz control.

7The phase settings allow the phase of the woofer sec- tion to be modified in the crossover area. This allows for a phase match between the ESL/transition-tower and the subwoofer. The phase dip switch should be set to 270° to start. We have found this setting to work well in most situations. To adjust the phase see figure four.

8Replace the lid.

9Plug the unit in.

10Turn the amplifier on.

Making It All Work Together (Part 2)

Note: This unit will generate electrical transients on its out- puts when the power is turned off or on. This can cause loud noises if the amplifiers are turned on.

Turn on both the woofer and ESL/transition-tower. Try turning the woofer level up and down on the EXOS. This will allow you to see how the crossover is meeting. If you turn the woofer up and a suck-out appears at the crossover frequency the phase switch on the EXOS needs to be adjusted.

Adjusting the phase switch is best accomplished by trying different settings with the amplitude of the woofer output matching that of the ESL. Find the setting that creates the biggest suck-out at the crossover point. Now flip the switches to 180° from that position. Almost always the 270° default position is the best.
