MartinLogan Aeon i [4/24] Peration
4 Operation
OPERATION
Because your Aeon i speakers use an internal power supply
to energize their electrostatic cells with high-voltage DC, they
must be connected to an AC power source. For this reason
they are provided with the proper IEC standard power cords.
These cords should be firmly inserted into the AC power
receptacles on the rear connection panel of the speakers,
then to any convenient AC wall outlet. The Aeon i’s integrate
a signal-sensing power supply which will switch off after a few
minutes of no music signal and requires less than two sec-
onds to recharge the panels when a music signal is present.
Your Aeon i speakers are wired for the power service supplied
in the country of original consumer sale. The AC power rating
applicable to a particular unit is specified on the packing
carton and on the serial number plate attached to the speaker.
If you remove your Aeon i speakers from the country of
original sale, be certain that the AC power supplied in any
subsequent location is suitable before connecting and oper-
ating the speakers. Substantially impaired performance or
severe damage may occur to an Aeon i speaker if opera-
tion is attempted from an incorrect AC power source.
WARNING! The power cord should not be installed,
removed, or left detached from the speaker while
the other end is 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 available whose
manufac-
turers claim better performance than standard heavy gauge
wire. We have verified this in many cases, and the improve-
ments 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.
We also recommend, if possible, that short runs of speaker
cable connect the power amplifier(s) and speakers and that
high-quality long interconnect cables be used to connect
the preamplifier and power amplifier. This results in the
power amplifiers being close to the speakers, which may
be practically or cosmetically difficult, but if the length of
the speaker cables can be reduced to a few meters, sonic
advantages may be obtained.
Connections are made at the signal input section on the
rear electronics panel of the Aeon i. Use spade connectors
for optimum contact and ease of installation. Make certain
that all of your connections are tight.
Be consistent when connecting the speaker cables to the
signal input terminals. Take care to assign the same color
cable lead to the (+) terminal on both the left and right
channel speakers. If bass is nonexistent and you cannot
discern a tight, coherent image, you may need to reverse
the (+) and (–) leads on one speaker to bring the system
into proper polarity.
WARNING! Turn your amplifier off before making
or breaking any signal connections!
Break-In
When you first play your Aeon i speakers, they will sound a
bit bass shy, due to the high-quality, long-life components
used in our woofer. Our custom-made, butyl surround woofer
requires 30 hours of break-in at 90 dB (moderate listening
levels) before critical listening. Break-in of the crossover com-
ponents (and, to a lesser degree, the stator) are equivalent.
The pressure compensation panels on the back of the stator
panel are passive tone-shaping devices that improve tonal
balance and increase dispersion without sacrificing efficiency.
Please do not remove or reposition these panels in pursuit of
higher hi-fi as their size and placement are crucial to the
Aeon i’s performance.
Jumper Clips
In some countries federal law prohibits MartinLogan from
supplying jumper clips. If none are found installed under your
speakers binding posts, please refer to Bi-Wire Connection
(page 6) for connection instructions. If jumper clips are
installed please refer to Single-Wire Connection (page 5)
for connection instructions.
