AMPLIFIER WIRING EXAMPLES
Example 1.
Basic wiring with one or two speaker
pairs.
This example with one or two 4 ohm systems can be
used with all DLS and GENESIS amplifier models.
The amplifier load is 2 ohms when connected in
parallel. Use 2/3-way systems or coaxial speakers.
All speakers must have an impedance of 4 ohms.

Example 2.
System with a front system and a
multimode connected subwoofer.
This system is similar to that on page 12. But here
we use a 6 dB filter (200 µF capacitor) to the front
system. With only one system and a subwoofer it´s
sufficient with a 6 dB filter. All speakers must have
an impedance of 4 ohms.

Suitable for: All DLS and GENESIS models.
Passive filters: To the sub: 12 dB low-pass filter
with 300 µF capacitor + 10 mH
coil giving 95 Hz x-over.
To the front system: 6 dB high-pass filter with 150 -
200 µF capacitor giving 180 Hz x-over. The original
filters in the systems must also be used.
Advantages: One amplifier can run both front
and rear speaker systems.
Disadvantages: You can´t balance the sound
levels between front/rear
speakers. (It´s possible to use
fixed resisors in series with the
speakers to adjust the levels.)
Amplifier load: 2 ohms
Passive filters: Not needed except for the filters
coming with the speaker kits.

Capacitors must be of bipolar type.
The coil must have low resistance, 0,5 - 0,7 Ω.
Advantages: One amplifier can be used for
the whole system.
Disadvantages: You can´t adjust the sound level
to the subwoofer.
Alternatives: If you use two subs they must be of
8 ohms impedance connected in
parallel to obtain a 4 ohm amplifier
load.

NOTE! In multimode operation the connected
subwoofers must never form an impedance
lower than 4 ohms.
