AC Power Connection

Your Motif X 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 con-
nection panel of the speaker, then to any convenient AC wall
outlet (see figure 1). Your Motif X integrates a signal sensing cir-
cuit which will switch the Motif X 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 Motif X 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 particular unit is specified
both on the packing carton and on the power supply.
If you remove your Motif X 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 Motif X speaker if operation 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.

Connections

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 dif-
ferences between wires of different gauge. The effects of cables
may be masked if the equipment is not of the highest quality.
Connections are made at the signal input section on the rear
electronics panel of the Motif X (see figure 1). Use spade con-
nectors for optimum contact. Make certain that all of your
connections are tight.
Be consistent when connecting speaker leads to the terminals on
the back of the Motif X. Take great care to assign the same color
to the (+) terminal on both the speaker and the amplifier.
WARNING! Turn your amplifier off before making or
breaking any signal connections!

Break-In

When you first begin to play your Motif X speaker, it will sound
a bit bass shy. This is due to the high-quality, long-life compo-
nents used in our woofer. Our custom made, butyl surround
woofer requires at least 80 hours of break-in at 90 dB (moder-
ate listening levels) before any critical listening. The break-in
requirements of the crossover components (and, to a lesser
degree, the electrostatic transducer) are equal.
