Tweeter Array Optimization
The XLS320, XLS340, XLS360 and XCS350 Loudspeaker
Systems incorporate a special feature in the Crossover
Network for optimization of the sound coming from the
five tweeter array, refer to figure 37. The three different
settings in the
crossover network
have to do with the
physical location of
the Loudspeaker in
the Home Theater
and/or Music System.
On the rear panel of the Loudspeaker System there is a
recessed connection
plate with binding
posts for connection of
hookup cables. Adja-
cent to the binding
posts on the same re-
cessed connection
plate, are two rows of
jacks with two McIn-
tosh Jumpers already
inserted, refer to figure
38. The default postion
of the jumpers for the
XLS320, XLS340, and
XLS360 Loudspeaker
Systems, is RIGHT,
refer to figure 39. The
XCS350’s default
postion of the jumpers
is CENTER, refer to figure 40.
For the best sound performance, it is important to make
sure the jumpers are set according to the Loudspeaker Sys-
tem location in the room. Refer to the chart below for the
correct Jumper positions; if necessary, remove the two
jumpers and reinsert them for the Loudspeaker location.
