12. The screws should pull the frame and
bracket together (sandwiching the
drywall) so that the frame is flush with
the wall surface.
13. Strip 1/4” of insulation from the end of
each wire.
14. Tightly twist the end of each wire until
no frayed ends remain.
15. Attach the speaker wires to the speaker
terminal connectors. Connect the
negative output from the amplifier to the
black terminal. Connect the positive
output from the amplifier to the red
terminal.
16. Set the speaker configuration switches
on the rear of the speaker (see Setting
the Speaker Configuration Settings).
17. Install the speaker in the frame. Screw
the enclosed self-tapping screws into
the dimples of the speaker baffle as
shown in Figure 2.
18. Repeat steps 1-17 for each speaker
being installed.
19. After making tonal adjustments on all
speakers (see Setting the Speaker
Configuration Settings), install the grill
into the speaker.

Crossover Mounted Switches
LST-CTR OAC Switch
The crossover on the back of the LST
-CTR
enables you to defeat the Off-Axis
Compensation (OAC) feature. Defeat OAC
when the speaker is mounted at ear level
directly in front of the primary listening
position, as would be the case when the
speaker is mounted behind a perforated
projection TV screen.
LST-RLS Main/Surround Switch
The crossover on the back of the LST-RLS
enables you to configure the speaker for
best performance as either a front “main”
speaker or rear “surround” speaker. When
the LST-RLS is used as a surround speaker,
set the switch to the “Surround” position to
provide a diffuse sound field which provides
a more convincing illusion of sound all
around the listener. When configured as a
surround speaker, the orientation of the
tweeter is no longer critical.
Front Baffle Switches
LST-CTR Acoustic Fine Tuning
The front-mounted switches on the LST-CTR
enable the speaker to be optimized
regardless of positioning or room acoustics
by providing 3dB of Treble Cut and 3dB of
Dialog Enhancement. Start by listening to
the speaker in the normal mode (switch is in
the “out” position). If the sound seems to
have too much treble, depress the switch
labeled Treble Cut to reduce the amount of
high frequencies.
If you desire to make dialog more
pronounced, depress the switch labeled
Dialog Enhance.
LST-RLS Acoustic Fine Tuning
The front-mounted switches on the LST-RLS
also enable the speaker to be optimized
regardless of positioning or room acoustics.
They provide 3dB of Treble and Bass Cut
respectively. Start by listening to the
speaker in the normal mode (switch is in the
out position). If the sound seems to have too
much treble, depress the switch labeled
T
reble Cut to reduce the amount of high
frequencies. If the sound has too much low
frequency output (because it is placed near
a corner perhaps) depress the switch
labeled Bass Cut.
