ConneCtion

Turn your amplifier

off before making or breaking any

signal connections!

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 dimin-

ishing returns setting in around #8 to #12.

A variety of cables are available whose manufactur-

ers 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 differences between wires of dif-

ferent gauge. The effects of cables may be masked

if equipment is not of the highest quality.

Connections are done at the signal input section

on the rear electronics panel of the speaker. Use

spade connectors for optimum contact and ease

of installation. Hand tighten the binding posts, but

do not overtighten—do not use a tool to tighten the

binding posts.

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, coher-

ent image, you may need to reverse the (+) and

(–) leads on one speaker to bring the system into

proper polarity.

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.

Please take note of the jumper clips installed

under the binding posts. These clips attach the

high-frequency 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. 1).

Only after jumper

clips are removed may you connect

individual runs of speaker cable

from your amplifiers to the high-fre-

quency and low-frequency signal input binding

posts. Damage will occur to your amplifiers if

the jumper clips are not removed.

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 termi-

nals 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 parallel connection (Fig. 2).

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.



Horizontal bi-amping allows you to use two differ-

ent types, models or brands of amplifiers (i.e. tubes

on top, transistor on the bottom). However, we rec-

ommend that you use two identical amplifiers (i.e.

same brand and model). If you must use two differ-

ent amplifiers, it is essential that they have the same

gain or that one of the two have adjustable gain

so that you can match their gain characteristics. If

the amplifiers of choice do not have the same gain

characteristics, then a sonic imbalance will occur.

With horizontal bi-amping, one amplifier drives the

high-frequency section of the speaker while the sec-

ond amplifier drives the low-frequency section. To

horizontally bi-amp your speakers you must loosen

the binding posts and remove the jumper clips.

Connect the low-frequency amplifier to the lower

set of binding posts of both speakers. Connect the

high-frequency amplifier to the upper set of binding

posts. Next, connect the left and right preamplifier

outputs to the appropriate left and right inputs of

both amplifiers (Fig. 3).

The very nature of vertical bi-amping dictates that

both amplifiers be identical. With vertical bi-amp-

ing, each of the stereo amplifiers is dedicated to

one speaker. For instance, the left channel of each

amplifier drives the low-frequency section while the

right channel drives the high-frequency section. To

vertically bi-amp your speakers you must loosen the

binding posts and remove the jumper clips from

both speakers. Starting with one speaker, connect

the right channel to the lower binding posts and

the left channel to the upper binding posts. Repeat

the same procedure for the other speaker. Connect

the left preamplifier outputs to both inputs of the left

channel amplifier and the right preamplifier outputs

to both inputs of the right channel amplifier (Fig. 4).

We do not recommend active bi-amplification. The

internal crossover can not be bypassed. This con-

nection method seriously degrades performance.

Although your speakers are designed to deliver a

superb sonic performance when placed close to a

wall, you may notice improved imaging and detail

if you are able to place the speakers (measured

from the tweeter and woofers) 2–3 feet from the

front wall and 2 or more feet from the side walls

(Fig. 5).

With the use of the included spikes, your speakers

will be firmly planted on the floor, bass will tighten,

and imaging will become more coherent. To avoid

floor damage, do not implement the spikes until

you are secure in the positioning. The included

spikes use a standard 1/4 - 20 thread.

1) Carefully lay your speaker on its side.

2) Remove existing feet or spikes. Thread new

spikes into holes and screw them in all of the

way. If the speaker does not sit level loosen

one spike until level is achieved.

3) Tighten the jam nut snugly by hand. Do not over

tighten the nut.

4) Right the speaker. Caution: Make sure your

hands and any cabling are clear of the spikes.

Do not slide speaker as spikes are sharp and

can damage your floor or carpet.

5) Adjust to level by rotating spikes. Tighten the

jam nut securely when satisfied that speaker is

level. Caution: “Walking” the speaker may result

in a broken spike.

We recommend against placing any loudspeaker

in direct sunlight. Ultraviolet (UV) rays from the sun

can cause deterioration of cabinet, speaker cones,

etc. Small exposures to UV will not cause a prob-

lem. Filtering of UV rays through glass will greatly

reduce the negative effects.
