MartinLogan i - Manual (Page 5)

We also recommend, if possible, that short runs of speaker
cable connect the power amplifier and speaker 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 done at the signal input section on the rear
electronics panel of the Cinema i (see figure 2). Use spade
connectors 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 Cinema i. 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!
You may have noticed a connection on the back of your
Cinema i’s labeled ‘Power Out’. The use of this connec-
tion will allow you to daisy-chain up to five low-voltage
MartinLogan products and eliminate the need for multiple
low-voltage power supplies.
A variety of low voltage interconnect cables may be pur-
chased at your local MartinLogan dealer. Please ask them
about options to fit your specific needs.
To use this connection option choose a primary speaker
(whichever speaker is most conveinent) and connect it as
instructed in the ‘Low-Voltage Power Connection’ section
on the previous page. To attach additional speakers, run a
low-voltage interconnect cable from the ‘Power Out’ to
the next speakers ‘Power Out’.
Break-In
When you first begin to play your Cinema i speaker, it will
sound a bit bass shy. This is due to the high-quality, long-life
components used in our woofer. Our custom made, butyl
surround woofer requires at least 30 hours of break-in at
90 dB (moderate listening levels) before any critical listening.
The break-in requirements of the crossover components
(and, to a lesser degree, the electrostatic transducer) are equal.
