BASS EXTENSION switch
The BASS EXTENSION switch can
be set to three different positions:
III for no bass equalization
III for medium bass equalization
(+3dB/40 Hz)
III for maxium bass equalization
(+6dB/40 Hz)
The purpose of the BASS EXTEN-
SION switch is to ensure that the
bass level suits the environment
and the placement of the speaker.
Which switch position to choose
depends on the distance from the
loudspeaker to corners and walls
and on the floor area of your
room.
The examples given in the table
are only meant as a guideline.
You may of course set the switch
to any of the three positions
which you prefer.
We recommend that the BASS
EXTENSION switches on the two
speakers be set to the same posi-
tion. If the two speakers cannot
be placed in comparatively similar
positions related to room bounda-
ries, both BASS EXTENSION
switches should be set to the posi-
