2 x AXIR + SX408A
Make sure that the AXIR design column speakers which will be used in
combination with the SX408A are switched to Low Impedance (6
Ohm).
This can be done by removing the front cover plate with the
AUDAC logo very carefully. This can be done by pressing on the
upper or lower side of this plate, or by sticking carefully a flat object
under the cover plate (e.g. a small screwdriver). The cover plate must
be coming loose without performing large forces.
After the cover plate is removed, the two power tap selector
switches are visible.
To switch the AXIR to Low impedance, the internal switches of the
speaker must be turned over. To reach the internal switches, the plate
with the two power tap selectors should be removed. This can be done
by loosening the 6 Phillips screws whereby it is attached.
Once these screws are loose, the plate can be carefully removed out
of the speaker. (Be careful with the wiring inside the speaker)
Then you will see that there are two switches provided at the side
of this plate. These switches are meant to convert the speaker for
use in 100V or low impedance applications.
Set these switches to Low Impedance to be used in combination to the SX408A.
After this is done, the speaker can be assembled again as it was originally.
Warning:
Make sure that the two switches are always both in the same position.
Make sure that it never occurs that one of them is on 100V and the other is in low
impedance position.
