The acoustical axis of the KH 420 starts from the midpoint of the mid range and tweeter dri-
vers.
X
Always point the acoustical axis, in the horizontal and vertical planes, towards the listening
position.
The acoustical axis is a line perpendicular to the loudspeaker’s front panel along which
the microphone was placed when tuning the loudspeaker’s crossover during design.
Pointing the acoustical axis, in the horizontal and vertical planes, towards the listening
position or center of the monitoring area will give the best measured and perceived
sound quality.
X
Position the loudspeaker so that there is a direct line of sight from the listening position to
the bass, midrange and tweeter drivers.
Connecting audio signals
X
Always use good quality cables with the correct impedance and appropriate termination to
avoid signal drop outs and to achieve the maximum cable lengths shown below:
Signal (connector) Impedance Cable length Connection method
Analog (RCA) low up to 10 m
(30') via an adapter (RCA-XLR)
to the ANALOG INPUT socket
(XLR)
H
(see page 14)
Analog (XLR) low up to 100 m
(300') directly to the ANALOG INPUT
socket (XLR)

(see page 14)
Connecting analog signals
Digital signals can only be connected when the DIM 1 module is installed.
X
Connect the left and right output of your analog audio source to the XLR input sockets of the
respective loudspeaker.
