Monolith III User's Manual

We know you are eager to hear
your new 

MONOLITH III 

loudspeak-

ers, so this section is provided to
allow fast and easy set up. Once
you have them operational, please
take the time to read, in depth, the
rest of the information in this
manual. It will give you perspective
on how to obtain the best possible
performance from this most
exacting transducer.

If you should experience any
difficulties in the set-up or opera-
tion of your 

MONOLITH III 

speakers

please refer to the 

Room Acoustics

,

Placement 

or 

Connection 

section

of this manual.

Should you encounter a persistent
problem that cannot be resolved,
please contact your Authorized
Martin-Logan dealer. He will
provide you with the appropriate
technical analysis to alleviate the
situation.

Step 1: Placement

Place each Monolith at least two feet from any wall and slightly angle them
toward your listening area. This is a good place to start. Please refer to the

Room Acoustics 

and

Martin-Logan Monoliths require AC power to energize their electrostatic cells.
Using the AC power cords provided, plug them in, making sure that you have
made a firm connection, first to the AC power receptacle on the rear panel of
the speaker and then to the wall outlet.  Extension cords may be used, if
necessary, since the AC power requirement of the Monolith is extremely small.

WARNING !

Turn your amplifier off before making or breaking any signal connections!

The chassis is earth grounded and can present a short circuit to your

amplifier if contact is made!

Installation in Brief

Use the best speaker cables you can! 16 gauge zip-cord is the minimum you
should use, and higher quality cables, available from your specialty dealer, are
recommended and will give you superior performance! Spade or banana
connectors are suggested for optimum contact and ease of installation.

Be consistent when connecting speaker leads to the terminals on the back of
the 

MONOLITH III

: take great care to assign the same color to the (+) terminal on

both the left and right channels. If bass is nonexistent and you cannot discern a
tight, coherent image, reverse the (+) and (-) leads on one side to bring the
system into proper polarity. Attach your speaker cables to the Amplifier Signal
input section of the 

IIIp INTERFACE 

if you have the 

MONOLITH IIIp

     or directly to the

appropriate Signal Input section on the back of the 

MONOLITH III 

if you are using

the 

MONOLITH IIIx CROSSOVER

. Please refer to the appropriate 

Connection

section of this manual for further details and instructions.
