2.2 Basic connection
This section provides information on the pin assignments and
basic set-up for the different enclosures. The "System
Configurations" section adds stereo system configurations
with or without sub-woofer reinforcement. The “Application
Examples” section adds complete application specific system
examples.
Some models, due to the complexities of their electronic
processing, require the indicated D.A.S. controller for the
system to run correctly. Others may use generic crossover
units with recommended settings, although the use of the
D.A.S. processors is recommended. In general, we stress the
importance of the use of the DAS processors, since they are
shipped with set energy balances and crossover frequencies,
and adjustments cannot be made that could endanger system
components. By using the DAS processors, we can ensure the
correctness of the sound and the reliability of the systems.
The following table shows the basic features of the DAS CT
controllers:
The following table shows the controller for each system with
or without subwoofer reinforcement.

If you wish to use a programmable digital processor, contact
your DAS distributor to get a list of set-up parameters for your
system.
R-112/115
Figures show the block diagram and basic set-up for models
R-112 and R-115. 300 to 400 watts of amplifier power are
recommended for the R-112, and 350 to 450 W for the R-115.
R-214
Figures show the block diagram and basic set-up for model R-
214.
R-212
Figures show the block diagram and basic set-up. A switch,
located at the input connector plate, allows to change
between passive (full-range) and bi-amplified use. In passive
use, the acoustical high frequency rolloff of the low frequency
section is used to crossover to the mid/high frequency
section, which utilises an equalised highpass filter network.
When using the system
in active (bi-amplified)
mode, use the D.A.S. CT-
2000 monophonic
electronic processor or a
24/dB octave electronic
crossover unit with the
crossover frequency set to 1200 Hz. We thoroughly
recommend the use of the D.A.S. CT-2000 (CT-1000 can also
be used for applications outside disco/club), since it is factory
shipped with appropriate crossover frequencies, which cannot
be accidentally modified.
