DLS Svenska AB WIRING EXAMPLES A4, DC - FEED DLS A4, ULTIMATE A4, HP-filtersetting 80-100Hz

WIRING EXAMPLES A4

1.Connecting a front system in stereo and a sub- woofer in mono bridge mode.

You can use all DLS coaxial, 2-way,

3-way systems and subwoofers in this example.

All speakers must be 4 ohm.

If the head unit has only one pre out a Y-cable must be used.

For power cable, speaker cable and fuse size selection see page 4.

HP-filter setting: 80-100 Hz

Use a 2 mm hexagon key to speaker terminals. Use a 2,5 mm hexagon key to DC input terminals on A1

Use a 4 mm hexagon key to DC input terminals on A2, A3, A4

	DLS A4 is 1 ohm stable. This means that you can connect two 4
	ohm subwoofers in parallel without damaging the amplifier. Two 4
	ohm subwoofers connected in parallel results in a 2 ohm load which
Subwoofer	the amplifier sees as a 1 ohm load.
	If you have a 4 ohm sub with dual voice coils you can connect the
4 ohm
	coils in parallel.
