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.
