Loudspeaker terminals
The high-quality terminals fitted to  loudspeakers are
designed accept the speaker cable after you unscrew the
cap covering the cross-hole.
Ensure that the screw terminals are properly tightened,
and that there are no projecting cable ends or stray wire
strands which could cause a short-circuit.
Note:
Current safety regulations prohibit the use of
loudspeaker cables terminating in banana plugs.
 Caution : Connect the red (+) loudspeaker
terminal to the red (+) terminal of the
amplifier. Connect the black (-) loudspeaker
terminal to the black (-) terminal of the
amplifier.
If the loudspeakers are connected with reversed polarity,
they will operate out of phase, and you will not be able to
obtain true stereophonic reproduction. The clearest
indication of a system connected with incorrect phase is
a dull, diffuse sound image and weak bass response.
TCI 3: high-frequency switch
The two high-frequency drivers in the TCI S3 can be
switched to any of three settings. In the top switch
position both tweeters operate in parallel. In the centre
position only the upper one operates, and in the bottom
position the lower high frequency unit is switched to
opposite phase. You may find that the top switch position
(direct sound projection) or the bottom switch position
(diffuse sound projection) offers better results for
surround sound, depending on the characteristics of the
listening room. In the centre switch position the
TCI S3
operates as a normal 2-way speaker. We recommend
that you carry out experiments to establish which switch
position you prefer.
Level adjustment TCI C2
The floor-standing loudspeakers of the TCI loudspeaker
series can easily be adjusted to suit the acoustic qualities
of the listening room, or to particular conditions and
speaker positions.
For example, it may well be necessary to reduce the bass
range if the speakers are set up close to a wall.
To facilitate these adjustments you will find three switches
(marked
BASS , MID and TREBLE ) on the rear terminal of
the speaker cabinet; each switch has three positions:
+1.5 dB, LIN and -1.5 dB .
TCI C2 level adjustment
BASS
If the loudspeakers are set up in a listening room a
considerable distance from the walls (> 1.5 m) we
recommend setting the switch to +1.5 dB.
If the loudspeakers are set up in a listening room close to
the walls , in our experience the best results in terms of
sound are obtained with the switch set to 0 dB.
If the loudspeakers are set up in one corner of the room ,
the result can be excessive bass emphasis. The -1.5 dB
setting compensates for this effect.
MID / TREBLE
On the rear of each speaker you will also find two
additional switches for adjusting the treble and mid-range
response to suit the listening room. The default position
for both switches is 0 dB.
These switches enable you to adjust the level by
+/- 1.5 dB, and the adjustment is designed to
compensate for very „hard“ (highly reflective) or very
„soft“ (highly damped) rooms. For rooms which
tend to
echo , we recommend the -1.5 dB setting.
In contrast, a lift of 1.5 dB may be helpful in rooms which
tend to damp sound down .
