TLC SPEAKER CABLE

FEATURES
The Tannoy TLC has been developed with
exclusive Van den Hul technology to create a
bi-wire loudspeaker cable of exceptional
quality.
Heavily shielded, the four main conductors
are laid in a star quad formation around a
centrally positioned ground (earth) lead. This
additional grounding cable is designed to
serve as a ground connection between the
loudspeaker drive units and the amplifier earth
terminal. The main conductors may be
arranged in bi-wire configuration or combined
in pairs to form a twin lead loudspeaker cable

WHY DRIVER EARTHING AND CABLE SCREENING?
Tannoy introduced the concept of a 'fifth terminal' on the loudspeaker connection panel specifically for
driver grounding (earthing) purposes. By enabling the drive unit chassis to be connected back to the
amplifier ground (earth) terminal this feature avoids the possibility of audio signal interference, caused
by external electromagnetic noise radiating into your power amplifier's signal (feedback) path, from
entering through the loudspeaker lines. Additionally, when using digital (switch-mode) power amplifiers,
any radiation of residual noise from the loudspeaker lines is prevented. In essence, these measures help
to keep your system's noise floor down, thereby allowing more detail to be revealed.
At high frequencies, power amplifier output impedance increases substantially as the negative feedback
becomes less effective. The result being that any RF interference picked up by the loudspeaker voice coil,
or the loudspeaker cables, will be fed back into the output stage of the amplifier and this then will enter
the forward signal path through the negative feedback loop. The resultant mix of the main audio signal
and the RF interference causes intermodulation distortion and, due to the broadband nature of the signal,
will blur and mask fine detail in the sound reproduced.
Exhaustive listening tests revealed a reduction in harshness or graininess in the sound, with more transparent
midrange and enhanced high frequency detail. Further investigation clearly showed that, despite the
presence of the magnet system around the voice coil, the mechanism influencing the sound quality was
the pickup of radio frequency interference (RF) by the voice coil itself. Electrically connecting or 'grounding'
the magnet assembly surrounding the voice coil, via the centrally located earth wire, back to the amplifier
chassis effectively shields the coil from RF interference therefore, improving sound quality.
Consequently it makes sense that the speaker cable itself should also be screened, with this braided layer
acting as a shield for the conductors themselves - this should be connected to the amplifier ground but
left unconnected at the loudspeaker end. In this way, the cable itself is prevented from behaving like an
aerial and picking up even more radio interference and noise.
• The stranded signal lines are made of highly
advanced Van den Hul Fusion technology
conductor material, embedded in a
conductive layer of Linear Structured
Carbon ®
• The sonic result is a very detailed signal
transmission, with a superb spacious
character and no sign of any sonic harshness
or lack of definition
• The jacket and insulation is very flexible
and acts as a mechanically superb insulation
material with very good mechanical
protection and chemical stability
• The heavy braided outer screen provides
additional protection against R.F.
interference. This shielding should be
grounded at the earth terminal on the
amplifier side and left disconnected at the
loudspeaker end
