tilt' (sw. 3 & 4).
"Treble tilt" attenuates the high
frequency response above 15 kHz by
two decibels. The "bass tilt" switches
provide three alternative attenuation
levels (-2, -4 or -6 dB) for low frequency
response below 150 Hz. "Bass roll-off"
switch changes the bass roll-off
frequency from 65 Hz to 85 Hz (-6 dB).
The factory setting is 'ALL OFF' to give
a flat anechoic response. See Figure
1 for suggested tone control settings
in differing acoustic environments.
Figure 5 shows the effect of the controls
on the anechoic response. Always start
adjustment by setting all switches to
'OFF' position. Then set the switch if
needed to the 'ON' position to select
the response curve needed.

It is vital that the loudspeakers are
correctly positioned in the room as this
greatly affects their performance. To
produce a true and accurate
soundstage the speakers must have
1) Wall hanging points
2) Threaded holes for Omnimount®

3) Tone control switches
4) Voltage selector

exactly similar frequency responses,
which is true in free field conditions.
In a room the frequency responses
change because the sound reflects
from the room's boundaries. We
recommend that the speakers are
positioned at the same height and
also at the same distance from the
front and side walls. Then the
reflections, and therefore the changes
to the frequency response, are as
similar as possible.
The DCW increases the directivity of
the loudspeaker; more sound is
directed on-axis and less to the sides.
Aim the loudspeakers towards the
center of the listening area to reduce
the effect of the room on the sound.
This is because more direct sound is
heard and reflections from walls which
degrade the sound are minimised.

Figure 4 shows the three possibilities
for mounting the HT205. On the base
of the speaker cabinet is a

6) RCA signal input (unbalanced)
7) Mains input
8) 3/8" UNC thread at the base
of the speaker
accommodate a standard microphone
stand.
There is a provision for Omnimount®
size 50 bracket, which can be attached
to two threaded holes at the back of the
loudspeaker with
screws. There are also three keyhole
slots for hanging the speaker on the
wall horizontally or vertically on a 4
mm screw with a suitable wide head.
Enclosed is a bag containing four large,
and four small friction pads. It is
suggested that the larger pads are
used on the base of the HT205, and if
mounted horizontally, the smaller pads
should be used on the side. There are
recesses where the pads should be
stuck.

Servicing and adjustment should only
be performed by qualified service
personnel. The amplifier's rear panel
must not be opened, except by
qualified service personnel.
The speaker should not be placed in
an enclosed position as there will be
insufficient airflow to cool the amplifier.
Do not use this product with an
unearthed mains cable as this may
compromise electrical safety.
To prevent fire or electric shock, do not
expose the unit to water or moisture.
