CONNECTIONS
AC Power Connection
Your Stage 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 Stage inte-
grates a signal sensing circuit which will switch the Stage
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 Stage speaker is 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 Stage 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 Stage speaker if opera-
tion is attempted from an incorrect AC power source.
WARNING! The power supply should not
be installed, removed, or left detached from
the speaker 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 lon-
ger 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 notice-
able than the differences between wires of different
gauge. The effects of cables may be masked if the equip-
ment is not of the highest quality.
Connections are made at the signal input section on the
rear electronics panel of the Stage (see figure 1). Use
spade connectors for optimum contact. Make certain that
all of your connections are tight.
Be consistent when connecting speaker leads to the ter-
minals on the back of the Stage. Take great care to assign
the same color to the (+) terminal on both the speaker
and the amplifier.
WARNING! Turn your amplifier off before mak-
ing or breaking any signal connections!
