Adjustment of the input sensitivity of
each speaker can be made to match
that of the decoder or other source, by
use of the input sensitivity control on
the rear panel (see figure 4). A small
screwdriver is needed for the
adjustment. The manufacturer default
setting for this control is -6 dBu (fully
clockwise) which gives SPL of 100 dB
@1m with -6 dBu input level. Note that
to get the full output level of 110 dB
SPL, an input level of +4 dBu is needed
in this setting.

The acoustic response of the system
may also have to be adjusted to match
the acoustic environment. The
adjustment is done by setting the three
tone control switches 'treble tilt', 'bass
tilt' and 'bass roll-off' on the rear panel
of the amplifier. The manufacturers
default settings for these controls are
'All Off' to give a flat anechoic response.
See Figure 1 for suggested tone control
settings in differing acoustic
environments. Figures 5 and 6 show
the effect of the controls on the
anechoic response. Always start
adjustment by setting all switches to
the 'OFF' position. Then set only one
switch to the 'ON' position to select
response curve needed. If more than
one switch is set to 'ON' (within one
switch group) the attenuation value is
not accurate.

The speakers are normally delivered
for vertical mounting. If horizontal
mounting is needed the DCW plate
can be rotated so that the GENELEC
logo is located at the bottom left corner
of the DCW. Remove the four corner
screws of the DCW and pull the plate
carefully out without stressing the wires
and the gasket. Rotate the plate 90
degrees to the appropriate direction
and remount the screws. Note that to
obtain a mirror image pair the DCW's
must be rotated 90° in opposite
directions on both speakers. In
horizontal mounting position the bass
drivers should point inwards to get
better low frequency summing.

The status indicator LED on the HT208
changes colour to indicate amplifier
status. If the LED is yellow, it indicates
that the "autostart" function has turned
the amplifier off. The amplifier returns
to "ON" mode and the LED changes to
green colour automatically when the
signal returns. If the LED turns red, it
indicates that the amplifier thermal
protection circuit has been activated.
Let the amplifier cool down and check
that there is sufficient clearance around
the amplifier for cooling.
The HT206 does not have the autostart
function, so it has only a green "ON"-
LED to indicate that the power has
been switched on.

There are no user serviceable parts
within the loudspeaker. Any
maintenance or repair should only be
undertaken by qualified service
personnel. Ensure that if fuse
replacement is required, only fuses of
the appropriate voltage and current
ratings are used. REMEMBER to
disconnect the power supply by
removal of the mains cable before fuse
replacement.
