Reference 100A can be connected in many 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 ohms subwoofers per channel in stereo, or max one 4 ohm
subwoofer in mono bridge mode. The built-in lowpass crossover is used.
3. In multimode with one system in stereo and one 4 ohm subwoofer connected in mono bridge mode
using a passive crossover filter for both the front system and the subwoofer. Connect as in example 5.4.
4. Using two Reference 100A you can run the front system on one of them (example 5.1) and the subwoofer
on the other (example 5.3). The highpass filter to the front system amplifier should be set at 80 - 100
Hz, or maybee higher. Make your own tests for best result.
5.1 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.
