Protect Your Investment

• Use an amp that approximately matches the speaker's specified power handling.

• To avoid damage, turn down the volume if the speaker sounds like it is distorting,

sounds harsh, or the bass begins to break up.

• Tone controls and equalizers may increase the likelihood of distortion, especially at

high volumes. Use these settings sparingly.

Break-In

When you first begin to play your speakers, they will sound a bit bass shy. This is due

to the high quality, long-life components used in the drivers. Allow approximately 72

hours of break-in at 90dB (moderate listening levels) before any critical listening.

General Speaker Placement

Choosing a Mounting Location

Install the speakers between wall studs or ceiling joists being careful to avoid electrical

wires behind the wall's surface. Please note, ML-67i should only be used in-ceiling.

Wall Rigidity Results in Better Sound

Increasing the rigidity of your walls may improve sonic performance. To do this con-

sider adding cross bracing inside of the wall approximately 12-inch (30cm) above and

below the speaker.

Achieving Superior Imaging

These MartinLogan in-wall and in-ceiling speakers offer superb imaging and flexible

placement in nearly any location. However, for best performance and imaging place

speakers equidistant from one another and avoid physical obstructions between the

speaker and primary listening position.

Balancing Hard vs. Soft Surfaces Improves High- and Mid-Frequency Performance

Rooms that are “over damped” with carpeting, drapes, and other sound absorbers can

cause your system to sound dull and lifeless. On the other hand, rooms can have so

many hard surfaces that the system sounds like a gymnasium. Experiment by adding or

removing soft surfaces until you find a mix that sounds good to you.

Balancing Bass Output

Corner placement of these speakers will reinforce their bass output. If you require bal-

anced output across the entire audio spectrum avoid mounting these speakers in a corner.

When choosing placement follow these simple tips:

• Place a minimum of 12-inches (30cm) from any wall corner.

• Place fronts/centers equidistant between 10–14 feet (3–4.3m) from the listening position.

• ML-67i: Install in-ceiling only.

Placement Options (ML-60, ML-65i, ML-66i, ML-80i)

Stereo and Home Theater Applications (no illustration)

MartinLogan Installer Series in-wall and in-ceiling speakers are ideal for 2-channel stereo

and multi-channel home theater installations. The guidelines from the previous section

apply to both in-wall and in-ceiling speakers.

Multiple Speakers, Distributed Audio (Fig. 1a)

In larger areas (offices, etc.) multiple speakers may be used to eliminate the sound

imbalances that occur with separate stereo speakers as people move around the room,

or are seated closer to one speaker than the other. Position speakers to achieve the

broadest sound coverage in the main listening area.

Placement Options (ML-62i Stereo Speaker)

ML-62i speaker offers two options for connection to an amplifier:

• 2-channels from a single speaker (2 amp channels connected to the speaker)

• 1-channel with wide dispersion (bridged for mono, 1 amp channel conencted).

2-Channel Sound From a Single Speaker (Fig. 2a)

Ideal in smaller areas a single speaker is the preferred choice. The ML-62i is connected

to the amp's left and right channels. Position the speaker to achieve the broadest sound

coverage in the main listening area. Connect left and right channels to the speaker.

5.1-Channel Wide Dispersion Surround Placement Using Two Speakers (Fig. 2b)

Place an ML-62i on either side of the listening area. Orient so one tweeter points toward

the front of the room and the other points toward the back. Bridge each speaker for mono

and connect the amp's left and right surround channels to the appropriate speakers.

6.1-Channel Wide Dispersion Rear Placement Using One Speaker (Fig. 2c)

Center one ML-62i behind the listening area, tweeters pointed toward the left and right

of the room. Bridge the speaker for mono and connect the amp's rear channel.

7.1-Channel Surround + Rear Placement Using Two Speakers (Fig. 2d)

Place one ML-62i on either side of the listening area. Orient so one tweeter of each

speaker points toward the front of the room and the other points toward the back.

Connect the amp's left and right surround and rear channels to the appropriate speakers.

7.1-Channel Rear Placement Using One Speaker (Fig. 2e)

Center one ML-62i behind the listening area with tweeters positioned toward the left and

right sides of the room. Connect the amp's left and right rear channels to the speaker.

Placement Options (Aimable ML-67i Speaker)

ML-67i speakers are optimized for use in rooms with ceiling heights ranging from 8–9

feet (2.4–2.74m). Point the tweeters toward the primary listening position. For overall

clarity and balanced bass performance, these speakers should be mounted in the ceiling

12 inches (30 cm) or more from the wall, as shown in Figs. 3a to 3f.

Left/Center/Right Placement (Fig. 3a & 3b)

Follow the general guidelines for speaker placement provided at the beginning of

the main section keeping in mind the distance from the front speakers to your primary

listening area should be 10–14 feet (3–4.3m), as shown. Point the drivers toward the

primary listening position.

Non-Direct Radiating Surround/Rear Placement

These speakers are also ideal for use as surrounds and rears. Aiming the speaker so sound

bounces off the walls creates an enveloping, reverberant sound field. Keep in mind that

speakers should be mounted 12 inches (30 cm) or more from the wall.

•

5.1-Channel Surround Placement (Fig. 3c): Position one speaker on either side of the

listening area, with drivers pointed toward the side walls.

•

6.1-Channel Rear Placement (Fig. 3d): Begin with ‘5.1-Channel Surround Placement’ (above).

Center one speaker behind the listening area with drivers pointed toward the back wall.

•

7.1-Channel Rear Placement (Fig. 3e): Begin with ‘5.1-Channel Surround Placement’

(above). Position another pair of ML-80i speakers behind the listening area, one slightly to

the right, the other slightly to the left, with drivers pointed to the back of the room as shown.

Direct Radiating Surround/Rear Center Placement (Fig. 3f)

The ML-67i may be used as direct-radiating speakers, positioned with drivers pointed

toward the listening area. Use Fig. 3f as a guide to positioning as you experiment to

achieve optimal surround sound in your room.

Connecting the ML-62i

2-channels from a single speaker: Connect two sets of speaker cables from your amplifier to the

left and right inputs on the ML-62i (Fig. 4a).

Single channel, wide dispersion: Connect one set of speaker cables to one set of binding posts

on the ML-62i and use matching cable to bridge the second set of binding posts (Fig. 4b).
