ULTIMATE A1-A2

Wiring examples DLS A1 & A2

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 main difference between DLS A1 and A2 is the lowpass filter and the power output. A1 has a 3-way filter selector under the bottom plate and A2 has a continously variable filter on the front.

DLS A1 and A2 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 crossover is used. (Connect to L+ and R-).

DLS A1 has a lowpass filter with two fixed frequencies that can be set under the bottom plate. DLS A2 has an inbuilt adjustable lowpass filter that should be set to approx. 70-80 Hz.

1.One speaker pair connected in stereo

You can use all DLS coaxial, 2-way or 3-way systems in this example. The speaker impedance must be 4 ohm.
