Installation
The acoustic system
The complete system consists of:
! Acoustic system
! 4 loudspeaker boxes
! 1 powercord
! 30 meter (90') loudspeaker cable
! 1 audio cable
Installing the loudspeaker boxes
First of all you have to install the loudspeakers in their correct location. The best result is
obtained by installing the loudspeakers in a square as large as possible around the “listener’s
location”. Normally this is the place where you as the organist are playing the organ.
The drawings below give a possible loudspeaker configuration in a square and an L-shaped
room.
Installing the acoustical
Determine the correct placement for the acoustical system control console considering the
length of the loudspeaker cables. Typically this is on top of the organ left or right of the music
rack.
Connecting the loudspeaker boxes
Cut the supplied loudspeaker cable in 4 (different) lengths to connecting the four loudspeaker
boxes. Split-up each end of the 4 loudspeaker cables for about 5 cm (2") and strip each wire
1cm ( 0.5").
