Low-Voltage Power Connection

Your Cinema i speaker uses an external low-voltage power
supply to energize its electrostatic panel. For this reason
the proper low-voltage power supply is provided. The
power supply should be firmly inserted into the 'Power In'
receptacle on the rear connection panel of the speaker,
then to any convenient AC wall outlet (see figure 1). Your
Cinema i integrates a signal sensing circuit which will
switch the Cinema i off after a few minutes of no music
signal, and requires less than two seconds to recharge the
panel when a music signal is present.
Your Cinema i speakers are provided with a power supply
for the power service supplied in the country of original
consumer sale. The AC power rating applicable to a par-
ticular unit is specified both on the packing carton and on
the power supply.
If you remove your Cinema i speakers from the country of
original sale, be certain that the AC power supplied in any
subsequent location is suitable before connecting the low-
voltage power supply. Substantially impaired performance
or severe damage may occur to a Cinema i speaker if oper-
ation is attempted from an incorrect AC power source.
WARNING! The power supply should not be
installed, removed, or left detached from the speak-
er while connected to an AC power source.

Signal Connection

Use the best speaker cables you can. The length and type
of speaker cable used in your system will have an audible
effect. Under no circumstance should a wire of gauge
higher (thinner) than #16 be used. In general, the longer
the length used, the greater the necessity of a lower gauge,
and the lower the gauge, the better the sound, with
diminishing returns setting in around #8 to #12.
A variety of speaker cables are now available whose
manufacturers claim better performance than standard heavy
gauge wire. We have verified this in many cases, and the
improvements available are often more noticeable than the
differences between wires of different gauge. The effects
of cables may be masked if the equipment is not of the
highest quality.
