TERMINAL PANEL CONNECTIONS AND DRIVER EARTHING
iw6 DS DISCRETE MODEL
I
n this model there are two robust spring loaded terminals designed to take substantial high
quality loudspeaker cable. Strip off approximately 8mm (1/4”) of the outer protective layer
and twist the inner cores together. Depress the spring-loaded terminal and insert the core
ensuring that correct polarity is maintained.
iw6 TDC DUAL CONCENTRIC
™
MODEL
The iw6 TDC Dual Concentric
™
model has an extra spring loaded terminal designed to
optimise performance further by taking advantage of the driver earthing facility.
Use a shielded or screened loudspeaker cable; connecting the screening termination to the
earth or ‘ground’ (green) terminal on the loudspeaker and to the ground or earth connection
on the amplifier. Alternatively if you are not using a screened loudspeaker cable but wish to
utilise the earthing facility, run a single cable between the earth or ‘ground’ (green) terminal
on the loudspeaker to the earth (ground) connection on the amplifier. Connect the positive
and negative cables In the same manner as in the discrete model while ensuring correct
polarity.
The earth (green) terminal comes fitted with a blanking plug. Remove this to insert the cable
but retain the plug for future use. The product should not be installed without either this plug
or a cable in place as the energy from the driver can in extreme cases cause audible
resonance.
WALL CLAMP MECHANISM
PLEASE CONSULT THE INSTALLATION SECTION
OF THIS MANUAL BEFORE PROCEEDING.
A unique six way clamp mechanism (patent applied for: 0316892.9)
has been designed to provide the acoustically optimum bond to the
wall surface without risk of distortion to the loudspeaker baffle.
As the six screws are tightened the immensely strong polycarbonate
clamping arms will automatically swing round into the locking position,
locating securely to the inside of the wall surface.
The design also allows for simple removal or reorientation of the
loudspeaker. The spring-loaded clamp mechanism ensures that as the
screws loosened (turned anticlockwise) the clamp arm travels along its
guide before turning itself into the rest position. The captive locking
system ensures that the clamp arm cannot drop off the end of the
screw to be lost in the wall cavity.
IMPORTANT
Get all the clamps in the rest position by loosening all screws before attempting
to remove the speaker from the wall.
