2. Positioning
0.5m - 1m
Speaker Installation
If using a projection television with an acoustically
transparent screen, position your HTM81 D4 or
HTM82 D4 speaker behind the centre of the screen.
Otherwise, position it either directly below or above the
screen using either a floor-stand, furniture unit or wall
shelf ensuring the speaker is as close to ear height as
possible.
If a floor-stand is to be used, we recommend the
FS-HTM D4. FS-HTM D4 is an adjustable centre
speaker stand that allows either HTM81 D4 or
HTM82 D4 to be tilted by either 4º or 8º. This range of
adjustment makes it easier for you to 'aim' the speaker
at your ear level when you are seated. It is important
for both safety and performance that the floor-stand
assembly instructions are followed.
If a wall-shelf or furniture unit is used, we recommend
using the foam bung inserts (supplied) to optimise
port performance (see Section 4: Fine Tuning and
Running In).
Note: If using a shelf, ensure that it is strong
enough to properly support the weight and fit
the 4 self-adhesive plastic feet to the underside
of the speaker.
3. Connecting
0.5m - 1m
Important Safety Notice
All connections should be made with
the audio equipment switched off. When
using audio equipment in normal operation, touching
uninsulated speaker terminals or wiring may result in
an unpleasant sensation.
The HTM81 D4 and HTM82 D4 speaker terminals
accept a variety of cable terminations: 4mm banana
plugs, 6mm and 8mm (1/4 in and 5/16 in) spades, or
bare wires up to 4mm (5/32 in) diameter.
Important Safety Notice
In certain countries, notably those in Europe,
the use of 4mm banana plugs is considered
a potential safety hazard, because they may be
inserted into the holes of unshuttered mains supply
sockets. In order to comply with European CENELEC
safety regulations, the 4mm holes in the ends of the
terminals are blocked by plastic pins. If you are using
the products in any country where these conditions
apply, you should ensure that any banana plugs cannot
be used in an unsafe manner by children or other
uninformed persons. The plastic pins can be removed
if you wish to use banana plugs.
Ask your dealer for advice when selecting speaker
cable. Keep its total impedance below the maximum
recommended in the speaker specification and use
a low inductance cable to avoid attenuation of high
frequencies.
There are two pairs of terminals at the back of each
speaker that enable bi-wiring (top). For conventional,
single wire connection, fit the supplied link wires to join
the like polarity terminals together.
Ensure that the positive terminals on the speaker (with
red ring) are connected to the positive output terminal
on the amplifier and the negative terminals on the
speaker (with black ring) are always connected to the
negative output terminal on the amplifier. Incorrect
connection will not result in damage but will cause
poor audio imaging and loss of bass. Always screw the
terminal caps down fully to prevent rattles.
