5. SYSTEM CONFIGURATIONS

NOTE: Extensions to the basic system are shown enclosed
inside a dotted line frame. Stereo configurations are used in
the examples.
Full-range
In this configuration we simply connect the amplifier to the
boxes. If more than one box is needed per channel, we will
simply parallel them, always taking into account the minimum
impedance that the amplifier will take, as detailed in the
"Connections" section.
Boxes with built-in transformers (suffix "T") will also be
connected in parallel, taking into account the amplifier power
capacity, as detailed in the "Connections" section.
Passive subwoofer reinforcement (monoamplification)
In this configuration the DAS SUB-18F subwoofer with built-in
crossover is connected to the amplifier. The mid-high box or
boxes get connected to the "OUT-SATELLITE" output of the
Sub-18F. This is a simple and cost effective way of adding
subwoofer reinforcement.
Connect only one DS-115 or DS-112 to the SUB-18F. Connect
two DS-108 units to one SUB-18F.
Normally, subwoofer reinforcement would only be used with
DS series.
Subwoofer reinforcement (biamplification)
In this configuration, an electronic crossover unit is needed
(such as the DAS CT-1), that divides the signal into subwoofer
and mid-high signal. Each of these frequency bands is
amplified separately and connected to the corresponding box
or boxes. If the DAS SUB-18F is being used as a subwoofer, it
is recommended that the built-in filter be disabled by following
the instructions in the SUB-18F's specification sheet.
If more than one box is needed per channel, we will simply
parallel them, always taking into account the minimum
impedance that the amplifier will take, as detailed in the
"Connections" section.
Factor/DS
The DAS CT-1 controller is a generic 2-way stereo crossover
for active subwoofer reinforcement, and is recommended for
its ease of use, although other 2-way crossovers can be used.
If the crossover you use does not have a monophonic
subwoofer output, simply connect each subwoofer crossover
output to each amplifier channel driving the subwoofers.
Use one DS-115 or DS-112 per every SUB-18F unit. Use two
DS-108 units per every SUB-18F unit.
Normally, subwoofer reinforcement would only be used with
DS series.
Biamplification with powered subwoofer
This configuration is similar to the one above, but in this case
we use the crossover that is built into the self-powered DAS
SUB-18A subwoofer.
If more than one box is needed per (mid-high) channel, we will
simply parallel them, always taking into account the minimum
impedance that the amplifier will take, as detailed on the
"Connections" section.
If more than one subwoofer box is needed per channel, we
will simply parallel them using the
powered subwoofer.
Use one DS-115 or DS-112 per every SUB-18A. Use two DS-
108 units per every SUB-18A unit.
