SINGLE WIRE CONNECTION
(MOTION 60XTi/50XTi/40i/35XTi/20i)
Please take note of the jumper clips installed under
the binding posts. These clips attach the high-fre-
quency and low-frequency sections of the crossover
together. Leaving these in place, connect the (+)
wire from your amplifier to either red (+) binding
post and the (–) wire from your amplifier to either
black (–) binding post (Fig. 1b).
WARNING! Only after jumper
clips are removed may you con-
nect individual runs of speaker
cable from your amplifiers to the high-frequency
and low-frequency signal input binding posts.
Damage will occur to your amplifiers if the
jumper clips are not removed.
JUMPER CLIPS
(MOTION 60XTi/50XTi/40i/35XTi/20i)
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’ for con-
nection instructions.
BI-WIRE CONNECTION
(MOTION 60XTi/50XTi/40i/35XTi/20i)
This connection method replaces the jumper clips
installed under the binding posts with individual runs
of speaker wire from your amplifier. This doubles
the signal carrying conductors from the amplifier to
the speaker, thus direct-coupling each portion of the
crossover to the amplifier.
To bi-wire you must first loosen the binding posts
and remove the jumper clips. Connect one set of
wires to the upper set of binding posts which con-
nect to the high-frequency drivers. Then connect a
second set of wires to the lower binding posts which
connect to the low-frequency drivers. Next, connect
both sets of wires to the appropriate terminals on
your amplifier. Please take care to connect both (+)
wires to the (+) amplifier terminals and both (–) wires
to the (–) amplifier terminals. This is known as a par-
allel connection (Fig. 2).
PASSIVE BI-AMPLIFICATION
(MOTION 60XTi/50XTi/40i/35XTi/20i)
For those that desire ultimate performance, these
speakers may be passively bi-amplified using the
existing internal passive crossover elements.
This method takes the bi-wiring concept one step
further. You will have a dedicated channel of
amplification directly connected to the high- and
low-frequency sections of the crossover. There are
two different methods for bi-amping with two stereo
amplifiers. The first and most common is referred
to as Horizontal Bi-amping. The second method is
referred to as Vertical Bi-amping. With either meth-
od you may use two stereo amplifiers or four mono
amplifiers, or two mono amplifiers and one stereo
amplifier. Get the idea? With either form of passive
bi-amplification, your preamplifier must have dual
outputs. If your preamplifier is not so equipped, you
must either purchase or construct a “Y” adapter.
