PASSIVE HIGH-PASS SETTINGS

The passive high-pass settings can be adjusted by changing the red and black jumpers found in the high-pass section of the ESL/Transition tower passive crossover.

WARNING! Before changing the passive-high pass options be sure to turn the amps off and unplug the Statement e2 ESL/Transition tower.

The design of these jumpers accommodates different lis- tening distances to the speaker (distance between listener and speaker). The unit is shipped in 15ft mode. If the user is only 10-feet away the jumpers need to be changed.

The jumpers are located near the side of the crossover located in the ESL/Transition tower bases (see figure 54).

There are red and black jumpers that are either connected or not connected through the screw terminal block (see figure 56 & 57).

WARNING! Never connect the red wires to the black. wires.

The High-Pass Settings

The 4 options are (from least output to most output):

10-Foot Mode (figure 58)

—Red not connected and black connected. —0dB

All-Closed Mode (figure 59)

—Red connected and black connected —200Hz–300Hz +1dB

All-Open Mode (figure 60)

Red not connected and black not connected —3dB peak at 300Hz

15-Foot Mode (default—(figure 61) —Red connected and black not connected —200Hz–300Hz +1dB

—3dB peak at 300Hz

Figure 55 demonstrates how these different settings effect the frequency response.

Note:

The ten-foot mode has been set to 0db.

The all-closed setting raises the output from 200Hz to 700Hz by 1db

The all-open setting adds a peak of 3db around 300Hz

The 15-foot mode adds both of the above changes
