DACS CALIBRATION (continued)
Before making adjustments, set the SPL meter according to the
DACS® Installers Manual or audio calibration disc instructions. If no
setting is recommended, set the SPL meter to “C” weighting and
“SLOW” response. Use the up and down MENU arrows to
manually scroll through menu items. Press the right MENU arrow
to select an output for adjustment, then use the up and down
MENU arrows to increase and decrease the level of the selected
output in 0.5dB increments within a range of -18 to +12dB. Adjust
all output levels to achieve the appropriate reading on the SPL
meter from the primary listening position. Press the left MENU
arrow to exit the selected output and return to the SPEAKER LEVEL
ADJUST menu.
Note:
SDP-40 Balanced output levels must be recalibrated
when output connections are changed from
unbalanced to balanced or vice versa. The balanced
outputs are approximately 6dB louder than the
unbalanced outputs.
SUB LIMITERS
Dolby Digital and dts(-ES) input types can produce low-frequency
peaks at much higher levels than 2-channel input types. In home
listening spaces, the subwoofer and its associated amplifier are
sometimes unable to reproduce these levels without overloading.
For this reason, the unit is equipped with internal sub limiters that
help prevent subwoofer signals from exceeding a designated value.
This parameter can be adjusted within a 75 to 115dB range.
Separate limiters are provided for the SUBWOOFER L/R and the LFE
outputs.
