3. Connecting
All connections should be made with the audio
equipment switched off.
The HTM1 D3 and HTM2 D3 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.
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.

Recommended
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.
4. Fine Tuning
HTM1 D3
Before fine tuning, make sure that all the connections
in the installation are correct and secure.
Moving the speakers further from the walls will
generally reduce the volume of bass. Space behind the
speakers will also help to create an aural impression
of depth. Conversely, moving the speakers closer to
the walls will increase the volume of bass. If you want
to reduce the volume of bass without moving the
speakers further from the wall, fit the foam plugs or,
for less severe bass reduction, the foam rings in the
port tubes (above).
If the bass seems uneven with frequency this will most
probably be due to resonance modes in the listening
room. Even small changes in the position of the
speakers or the listening position can have a profound
effect on how these resonances affect the sound.
Try moving the listening position or locating the
speakers along a different wall. The presence and
position of large pieces of furniture can also influence
resonance modes.
