YOUR NEW SPEAKERS
MLT-1 5.1 speakers are magnetically shielded for use near a CRT television or video screen.
Keyhole slots on the rear allow them to be mounted on a wall (hardware not included).
Your speakers can also be placed on a bookshelf or desk.
POWER REQUIREMENTS
The ‘Watts’ (W) rating indicated on the rear panel is the maximum AC power your subwoofer
will draw when producing its maximum power output. However, the actual wattage draw
will vary with the bass content of the program material.
HOW TO AVOID SPEAKER DAMAGE
Use an appropriate amplifier. At high volumes, a very powerful amplifier can
overdrive your speakers and damage them. On the other hand, if your amplifier isn’t
powerful enough, it can produce clipping distortion that can easily damage high-frequency
drivers. (See your Dealer.)
Don’t be fooled by your amplifier’s volume control. It adjusts listening level—it does
not indicate power output. If your speakers begin to sound harsh or grating, or if you hear
the bass breaking up, turn the volume down immediately or you will damage your speakers!
This type of damage constitutes abuse and is not covered by warranty!
Tone controls and equalizers can demand even more power from an amplifier, lowering
the point at which it produces clipping distortion. Use them sparingly, if at all, and do not use
them when listening at loud levels.

SPEAKER PLACEMENT
Figure 1 provides a general guideline to help you get the best performance from your
new system.
FRONTS (Left/Right) - MLT-1 Speakers
For the most accurate timbral balance, place your front speakers so that their high-frequency
drivers are approximately ear level (see positioning 1 and 2). Measure the distance from
the listening area to your speakers. For optimal imaging, place the speakers approximately
3/4 of that distance from each other. MLT-1 speakers can be placed on a shelf, or wall
mounted (Fig. 2 on page 7)
CENTER SPEAKER - MLT-1 Center Speaker
Place the center speaker (see position 3) above or below your TV, whichever position is
closer to ear level. Position it flush with the front of the TV to minimize unwanted sound
reflections. It should be about the same distance away from the primary listening area
as the front speakers. (Some Audio/Video receivers and processors can electronically adjust for
differences in distance.) Your center speaker can be placed on top of a TV, on a shelf, or
wall mounted (see page 7 for Wall Mounting).
SURROUND SPEAKERS - MLT-1 Speakers
The surround speakers should be kept well away from the listening area for optimal surround
performance.
5.1 Surround Configuration
Position speakers on each side of the listening area, (see position 4 and 5 in diagram).

WALL MOUNTING
If you are not comfortable performing the following mounting procedures, have a professional
perform the installation (see your Dealer).
FLUSH TO WALL USING KEYHOLES
NOTE: When mounting the MLT-1 center channel, if you run speaker cable down the
face of the wall, apply self-adhesive bumper pads (included) to rear corners of enclosure
to accommodate the cable (see Figure 2).
1. Using #10 screws (not included) screw into the stud. (If model has two key holes,
measure distance apart and use two screws). If you cannot locate a stud, use
appropriate mounting hardware that will hold screws securely (see your Dealer).
Do not screw all the way in, head should stand out approximately 3/8 inch (9.5
mm). With the MLT-1 center channel, head should stand out 5/16 inch (8 mm). If
using bumper pads add 1/8 inch (3 mm) to the amount head stands out.
2. Connect speaker cables as outlined in “Speaker Connection” section of this manual.
3. Align keyhole to screw head, and using an “in and down” motion mount speaker to wall.

SPEAKER CONNECTION
Turn your amplifier OFF before connecting speakers.
This will avoid damage which could result from accidental
shorting of speaker cables.
Your speakers are equipped with binding posts that can be used with banana, pin or spade
connectors, as well as with bare wire. Using high-quality speaker cable (not included, see
your Dealer), connect one speaker at a time to your receiver/amplifier. Connect the red
(+) amplifier terminal to the red (+) speaker terminal and the black (–) to the black (–) (Fig. 3).
Tighten the posts firmly by hand, but don’t over-tighten them.
Turn your amplifier on and listen to your speakers. If you notice a complete lack of mid-bass
and a dislocated image, one or more of your speakers may be connected out-of-phase (their
polarity is reversed). Re-check to ensure that each speaker’s cable is connected with correct
polarity: red (+) to red (+) and black (–) to black (–). Make sure wires are firmly fastened.

THE SUBWOOFER
To achieve optimal bass performance for music and home theater, please read through
the guidelines for subwoofer placement that follow.
SIGNAL INPUTS
Low-Level Input
Allows connection from the LFE or Right/Left Output of an A/V receiver, processor or other
suitable low-level source.
CONTROL FACILITIES
Auto On/Standby
The subwoofer will turn on when it receives an input signal and the LED will turn Green. If no
signal is sensed for a period of time, the subwoofer will automatically switch to Standby and
the LED will turn Red.

Control Level
Balances the subwoofer output level to your speaker system’s output.
Low Pass Filter (Hz) Control
Controls the subwoofer’s upper-frequency cut-off to match the low-frequency characteristics
of your speakers.
Phase
Changes the phase of the subwoofer by 180° relative to your speakers.
SUBWOOFER PLACEMENT
We recommend positioning your subwoofer close to the wall, between the front speakers.
Corner placement, Fig. 4 (1) provides the most bass, but sometimes at the expense of
accuracy. A subwoofer placed near a wall (2) usually provides a good balance of quantity
and accuracy.

SUBWOOFER CONNECTION
SAFETY PRECAUTION: Before proceeding with this section be sure to read
and follow all safety precaution instruction notices at the beginning of this manual.
Turn all components OFF before connecting the subwoofer.
Ensure subwoofer is installed in a location where any rear amplifier
parts (panels, heatsinks, etc.) cannot be accidentally touched.
We recommend the use of high-quality cables and connectors when hooking up your subwoofer
(see your Dealer).
Low-Level Input (Fig. 5)
(For use with a receiver, processor or control unit with a LFE-Out jack.)
Using an RCA-to-RCA interconnect cable connect the subwoofer using the (LFE) Right input.
SETTING SUBWOOFER CONTROLS
When setting up your subwoofer and fine tuning it with your system, use music and video
soundtracks that you know well. They should contain selections with extended bass that is
continuous and repetitive. Set any tone or equalizer controls on your receiver or preamplifier
to flat (zero) and switch any loudness controls off.
Room acoustics vary. Experiment with subwoofer placement to find the best position. Certain
subwoofer positions may cause some bass frequency cancellation—when your speakers
and subwoofer are “out-of-phase” they work against each other through the crossover region
and bass is reduced. If bass sounds “weak” or “dislocated,” change the phase according
to the instructions in point 4, on page 11. When adjusting your subwoofer, remember
that bass should not be overbearing—the subwoofer should not draw attention to itself—but
it shouldn’t be “thin” or difficult to hear, either. Use the following set-up tips to fine-tune
subwoofer bass in your listening room:

SETTING SUBWOOFER CONTROLS (continued)
1. Turn the Low Pass Filter (Hz) Control to the middle of the “Normal” range.
2. Slowly rotate the Level Control until you match the subwoofer output level with
the level of your speakers. Bass should be clearly audible but not intrusive.
3. If the sound is too “thin” set the Low Pass Filter Control higher than the “Normal”
range; if the sound becomes “boomy” set the Low Pass Filter Control lower than
the normal range.
4. If the bass sounds weak or “dislocated” you may have a phase alignment problem.
Your MLT-1 subwoofer has a Phase Switch which is normally set to the 0° position.
Switch it to the 180° position—this will switch the phase of the subwoofer by 180° relative
to your speakers. Listen to determine if you hear more bass. If you don’t hear more bass,
return the Phase Switch to its original position and then experiment with subwoofer
placement to find an area of the room where there is less bass cancellation.

(FAQ) FREQUENTLY ASKED QUESTIONS
How do I clean my speakers and subwoofer?
Just use a dust free cloth or a soft brush to remove the dust from your speakers. We recommend
speakers better than anything else we have tried.
What size amplifier should I use?
We recommend an amplifier with 50 watts per channel for most applications. Probably less
would be adequate when used in home theater where a subwoofer is employed. The speakers
will perform well with either a tube or transistor amplifier, and will reveal the sonic character
of either type.
Could you suggest a list of suitable electronics and cables ideal for
MartinLogan speakers?
The area of electronics and cable choice is probably the most common type of question
that we receive. It is also the most subjective. We have repeatedly found that brands that
work well in one setup will drive someone else nuts in another. We use many brands with great
success. Again, we have no favorites; we use electronics and cables quite interchangeably. We
would suggest listening to a number of brands—and above all else—trust your ears. Dealers
are always the best source for information when purchasing additional audio equipment.
Is there likely to be any interaction between my speakers and the
television in my A/V system?
No. The MLT-1 and MLT-1 center speakers are shielded and can be used with a CRT television.
Will exposure to sunlight affect the life or performance of my speakers?
We recommend that you not place any loudspeaker in direct sunlight. The ultraviolet (UV)
rays from the sun can cause deterioration of grill cloth, speaker cones, etc. Small exposures
to UV will not cause a problem. In general, the filtering of UV rays through glass will greatly
reduce the negative effects.
Is it safe to set things on my subwoofer?
While your MLT-1 subwoofer is designed with a durable, stain-resistant surface, we advise you
not to set anything on your MLT-1 subwoofer—especially containers holding liquids.
Is there likely to be any interaction between my subwoofer and the
television in my Audio/ Video system?
Yes. The MLT-1 subwoofer doesn’t use a shielded driver. We recommend 3 feet between
the MLT-1 subwoofer and video components that are susceptible to magnetic fields,
such as CRT televisions.
12

Will my electric bill go 'sky high' by leaving my subwoofer plugged
in all the time?
No. The MLT-1 5.1 subwoofer, when the power switch is set to ‘Auto On’, will draw about
12 watts when idle and only 12 watts in standby mode.
Should I unplug my subwoofer during a thunderstorm?
Yes, or before. It's a good idea to disconnect all of your audio/video components during
stormy weather.
