DLS Svenska AB A1 - Manual (Page 18)

DLS A6 is 1 ohm stable. This means that you can
connect four 4 ohm subwoofers in parallel without
damaging the amplifier. If you have a 4 ohm sub
with dual voice coils you can connect the coils in
parallel, one coil to each amplifier output.
NOTE!
The speaker output terminals are internally
connected in parallel. This is a mono amplifier
so it is not able to connect the outputs in bridge
mode. The double terminals are only for easier
connection of more than one subwoofer.

Connection of two 4 ohm
subwoofers
You can use all DLS subwoofers in this
example. All speakers must be 2-4 ohm. If you
have subwoofer with dual voice coils, connect
one voice coil to each output terminal. For
power cable, speaker cable and fuse size
selection we refer to page 2.
PHASE SHIFT CONTROL
The Phase shift control is variable from 0 to
+180 degrees. With this control you can fine
tune your subwoofers so they play in phase with
the rest of your system.
This feature is extremely useful when fine tuning
the different speakers and amplifiers of a SPL
competition vehicle.
REMOTE BASS LEVEL & PHASE SHIFT
A remote bass level & phase shift control is
included. This allows you to adjust the bass
level and phase shift from the front seat of your
car.
Connect it to the socket marked Remote Bass
Level. When using a remote level control you
must activate it by pushing the switch on the left
side of the socket, to IN-position.

WIRING EXAMPLES A6
Phase
Level
DLS A6 has a built-in fan for cooling. The fan is
mounted in the bottom plate of the amplifier.
To get the best performance and cooling, mount the
amplifier on spacings. Doing so the fan can get fresh
air for best possible cooling.
The amplifier becomes very hot, especially when
loaded down to 1 ohm. When using 1,33 and 1 ohm
loads we recommend the use of external cooling fans
as well.
