Digital part description
The SDD3 has three main display screens for setup and input levels indication. Main screens are: LEVEL - for input levels
indications, DELAY for delay setup and MENU for attributes settings. For switching between these screens use FUNC/EXIT
button.
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 sensitivity. 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
cardioid pair.
