Connections :
For optimal sound reproduction, we suggest you choose a loudspeaker cable of
sufficient high quality to connect your amplifier to your TRIANGLE loudspeakers.
TRIANGLE’s high definition OFC cable will guarantee the best results. You should
use cables of the same length for the left and right channels and take special care
to respect the + and - polarities for each channel.
RECOMMENDATIONS FOR USE
ATTENTION:
If one of the speakers is placed next to a television, color settings may be affected
by the speaker’s magnetism. Keep a minimum distance of 1 m. This precaution
is not necessary for central speakers, which are shielded (protected against
magnetic field interference).
Bi-wiring and bi-amplification
For those wishing to improve their listening system further, it is possible to use
bi-wiring or bi-amplification. All loudspeakers in the Signature range (except rear
loudspeaker) can be bi-wired or biamplified.
With bi-amplification, interference between the woofers and other drivers is
totally eliminated, as each one is driven by its amplifier. It is obligatory to use
identical amplifiers to conserve the uniformity of the loudspeaker.
To do this, remove the terminal connection straps and use two stereo amplifiers.
On the speakers, the upper terminals are the signal inputs for the midrange
treble band, and the lower terminals are the signal inputs for the bass.
Use one amplifier to feed the bass, and the second for the midrange and treble
(see the diagram below).
