The next page shows the EQ settings. The LS1 EQ can be used to apply some gentle acoustic

correction in the bass and adjust the treble to taste. There‘s an option to save up to 4

preferences, that can be used for different listening conditions. One setting can be saved in the

LS1 as the standard EQ curve which is used at power up.

Filter Presets - If the ’Flat‘ preset is selected, the faders of the EQ cannot be operated. The ’EQ‘

button in the main window of the LS1 remote software will be turned ’off‘. By clicking the ’Last

Saved‘ preset, the display shows the current setting of the LS1 internal memory. Again, the

faders can not be used. If you select one of the four remaining presets, the EQ faders become

functional and can be set to taste. By clicking the ’Save in LS1‘ button you save an EQ setting to

the LS1 internal memory. This EQ will be used when the remote software is not running.

Preset Name - Here you can change the name of the selected preset. By default the preset

names are 1, 2, 3 and 4.

Low Shelf - The faders on the left of the graph control a low shelf EQ. This lter inuences the

energy below the so called ’bafe step‘ of the LS1, which is the frequency below which the LS1

starts to radiate energy omnidirectionally (approximately 250 Hz). If the LS1‘s are placed close

to a wall, you may like to attenuate the bass a bit since the energy radiating to the back is now

reected in phase always and adds up to the direct sound.

There are two controls to set the left and right channels independently. By ticking the ’Link‘

option, both faders move in unison, with a possible offset. Double clicking on a fader sets it to

0 dB. The purpose of setting a different low shelf lter for left and right is to compensate for a

possible difference in the acoustic environment of the left and right speaker. Imagine the left

speaker being placed in a corner and the right speaker just against a wall. Every boundary gives

an increased response in the low end due to reections. The left speaker will therefore receive

more reected energy from nearby surfaces than the right speaker. If you compare the bass of

the two speakers you will notice it is louder on the left. In this case, adjust the two low shelf

lters untill the low end on both speakers sounds as even as possible. Mark that moving the

speakers around a bit can have a dramatic inuence on the low end response and it is certainly

worthwhile to spend some time optimizing the speaker positions before using the low shelf EQ.

High Shelf - The high shelf fader controls the treble EQ for left and right speaker simultaneously.

If the fader is set to 0 dB, the frequency response at the listing position is linear up till very high

frequencies (when the ’Toe-in angle‘ setting of the LS1 page is set correctly). In case you like to

adjust the treble response to your own taste, please use this high shelf EQ.
