WIRING EXAMPLES DLS A3
On the following pages you find some examples of how to connect the amplifier for different use. The
drawings show normal level and filter settings. The two channels are divided into two separate mono
amplifiers. There are separate DC inputs for each channel but they are internally connected with each other.
You can feed the amplifier with double DC feeds if you want a minimum of voltage drop, or you can also use
the extra DC-input for the connection of a Power capacitor as in the example.
DLS A3 can be connected in different ways:
1. As a stereo amplifier connected with a speaker system of coaxial, 2-way or 3-way type.
Two speaker systems can be connected in parallel, one front and one rear system.
2. As a subwoofer amplifier with max two 4 ohm subwoofers in mono bridge mode. The built-in lowpass
filter is used. (Connect to L+ and R-).
1. In stereo with one front and
one rear speaker system.
You can use all DLS coaxial, 2-way or
3-way speaker systems in this
example. Speaker impedance must be
4 ohm.
For power cable, speaker cable and
fuse size selection see page 4.

If you have problems
with the mid bass dri-
ver "reaching the bot-
tom" (the voice coil
touches the bottom
pole plate) at high
volumes, use the HP-
filter to avoid this with
a setting at 50 - 80 Hz
or higher. Make your
own tests.
