The SETUP Menu
SDP-40
The parameters on the SYNTHESIS 7CH SETUP menu are not
adjustable, with the exception of REAR L/R. The default value of
REAR L/R is 80Hz, which activates the rear speakers for use in a
SYNTHESIS 7CH setup. This setup requires rear speakers to be
operational. When set to OFF, the REAR L/R outputs are deactivated
and the Surround EX parameter (page 5-24) cannot be set to ON.
Note:
The SYNTHESIS 7CH SETUP menu is not adjustable,
with the exception of the REAR L/R parameter. To
customize settings, use the CUSTOM SETUP menu
(see page 3-18).
SPEAKER DISTANCES
Selecting SPEAKER DISTANCES accesses the SPEAKER DISTANCES
menu, which can be used to set the listener position relative to the
speakers. The unit features a speaker distance control, used for
entering distances for all speakers. This feature is not a substitute
for proper speaker placement, though it does help to ensure
accurate signal arrival times at the primary listening position.
Speaker distances can be set within a range of 0 to 30ft or 0 to
12m. The UNITS parameter selects the desired unit of
measurement. The unit will automatically convert feet to meters or
meters to feet when the parameter setting is changed. To
determine the appropriate setting, measure the distance between
the primary listening position and the front baffle of each speaker.
Enter the closest available value in the corresponding parameter.
Press the right MENU arrow to select the desired speaker for
adjustment. Press the up and down MENU arrows to increase and
decrease the distance in 0.5ft or 0.2m increments. Press the left
MENU arrow once to exit the selected parameter, and twice to exit
the SPEAKER DISTANCES menu.

When a JBL Digital Equalizer is
used in the system, speaker
distances should remain at their
factory-default settings (left). The
digital equalizer will perform
arrival time correction when
calibrated.
