LEVEL
For optimal analog to digital converter driving
the full range channels (channel A and B) are
equipped with ADC sensitivity control which
increases input level and reduces output level
at the same time, so the level pass in the SDD3
is not changing when adjusting the ADC sensi-
tivity. ADC sensitivity allows the optimal setup
of signal to noise ratio. The input level can be
seen on the input level meters indicators. For
optimal ADC driving run the level meters so
that the signal will exceed 0dB meter level, but
never reaches clip level. Level meters are
equipped with peak memory and 2 seconds
auto reset.
DELAY
Delay can be set for each channel individually,
delays can be set in time or distance. Required
delay is set by changing numbers on math
point position. Delay numbers are changed by
rotating the rotary encoder. Math position is
changed by pushing the rotary encoder
(ENTER). Delay changes are reflected in real
time.
The current selected channel can be switched
by pressing CHAN/NEXT button. The selected
channel is incicated by an LED.
The subwoofer channel can be set in 32 fixed
steps, with step increments of 0.31ms. The
subwoofer channel has two outputs, these
outputs can be set individually in normal mode
or linked in cardioid mode.
In normal mode, delay can be set in time or
distance, in cardioid mode, delays are set in
distance. The distance between the front and
rear cardioid subwoofer is precalculated by a
set cardioid frequency. Cardioid frequency can
be set in the range of 40 to 100Hz. In cardioid
mode cardioid delay is set for the entire cardi-
oid pair.
