WIRING EXAMPLES A6

Connection of two 4 ohm subwoofers

ULTIMATE A6

DC - FEED DLS A6

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.

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.

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.
