Step 1: Unpacking
Remove your new Cinema speaker from the packing.
Step 2: Placement
Place the Cinema directly between your front left and right speakers. This is a good place to start. Please see the Installation section (page 6) of this manual for more details.
Step 3: Power Connection (AC) (see warning)
MartinLogan speakers require AC power to energize their electrostatic cells. Using the AC power cords provided, plug the Cinema in
first to the AC power receptacle on the
rear panel of the speaker
, making sure that you have made
a firm
connection, and then to the wall outlet. Please see the
Operations section (pages 5) of this manual for more details.
Step 4: Signal Connection
Use the best speaker cables you can. Higher quality cables, available from your specialty dealer, are recommended and will give you superior performance. Spade connectors are suggested for optimum contact and ease of installation.
Attach your speaker cables to the Signal Input section on the rear panel. Be consistent when connecting speaker leads to the terminals on the back of the Cinema: take great care to assign the same color to the (+) terminal on both the speaker and the amplifier. Please see the Operations section (pages 5) of this manual for more details.
Step 5: Listen and Enjoy
Now, you may turn on your system and enjoy!

4 Introduction

INTRODUCTION

Congratulations! You have invested in a new world of home cinema!
The MartinLogan Cinema represents the culmination of an intensive, dedicated group research program directed toward establishing a world class reference monitor utilizing leading-edge technology, without compromising durability, reliability, craftsmanship or aesthetic design.
The advantages of MartinLogan hybrid technology will present themselves to you from the moment the movie begins. The box effect (a phenomenon similar to cupping your hand around your mouth when speaking) produced by dynamic midrange drivers is absent and the natural openness of the human voice comes through. Never before in home theatre has the midrange been so clear. Sounds float around the screen clearly defining the area from where they were created, not the area of the speaker that created them. This superior performance is made possible through the use of our proprietary curved electrostatic transducer. This is the same design technology that is used in the state-of-the-art MartinLogan Loudspeaker Systems.
The materials in your new Cinema speaker are of the highest quality and will provide years of enduring enjoyment and deepening respect. The cabinetry is constructed from the highest quality composite material for acoustical integrity and is finished with our attractive custom matte finish.
Through rigorous testing, the curvilinear electrostatic panel has proven itself to be one of the most durable and reliable transducers available today. Fabricated from a custom tool punched high-grade steel, the patented panel is then coated with a special polymer that is applied via a proprietary electrostatic deposition process. This panel assembly houses a membrane just 0.0005 of an inch thick. Ruggedly constructed and insulated, as much as 150 watts of continuous power has driven the Cinema’s energized diaphragm into massive excursions with no deleterious effects.
The other sections of your User’s Manual will explain in detail the operation of your Cinema speaker and the philosophy applied to their design. A clear understanding of your speakers will insure that you obtain maximum performance and pleasure from this most exacting transducer. It has been designed and constructed to give you years of trouble-free listening enjoyment.
Because your MartinLogan Cinema uses an internal power supply to energize its electrostatic cells with high-voltage DC, it must be connected to an AC power source. For this reason it is provided with the proper IEC standard power cord. This cords should be firmly inserted into the AC power receptacles on the rear connection panel of the speaker, then to any convenient AC wall outlet. The Cinema integrates a signal sensing power supply which will switch off after a few minutes of no music signal, and requires less than two seconds to recharge the panels when a music signal is present.
Your Cinema speaker is wired for the power service supplied in the country of original consumer sale. The AC power rating applicable to a particular unit is specified both on the packing carton and on the serial number plate attached to the speaker.
If you remove your Cinema speaker from the country of original sale, be certain that AC power supplied in any subsequent location is suitable before connecting and operating the speakers. Substantially impaired performance or severe damage may occur to the Cinema speaker if oper­ation is attempted from an incorrect AC power source.
WARNING! The power cord should not be installed, removed, or left detached from the speaker while the other end is connected to an AC power source.

Signal Connection

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 diminishing returns setting in around #8 to #12.
A variety of speaker cables are now available whose manufacturers claim better performance over 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 different gauge. The effects of cables may be masked if the equipment is not of the highest quality.
We also recommend, if possible, that short runs of speaker cable connect the power amplifier and speaker and that high quality long interconnect cables be used to connect the preamplifier and power amplifier. This results in the power amplifiers being close to the speakers, which may be practically or cosmetically difficult, but if the length of the speaker cables can be reduced to a few meters, sonic advantages may be obtained.
Connections are done at the Signal Input section on the rear electronics panel of the Cinema (see figure 1). Use spade connectors for optimum contact. Make certain that all of your connections are tight.
Be consistent when connecting speaker leads to the terminals on the back of the Cinema: take great care to assign the same color to the (+) terminal on both the speaker and the amplifier.
WARNING! Turn your amplifier off before making or breaking any signal connections!

Break-In

When you first begin to play your Cinema speaker, it will sound a bit bass shy. This is due to the high-quality, long-life components used in our woofer. Our custom made, butyl surround woofer requires at least 30 hours of break-in at 90 dB (moderate listening levels) before any critical listening. The break-in requirements of the crossover components (and, to a lesser degree, the electrostatic transducer) are equal.

6 Installation
On the Television
If your television provides a wide, level and stable platform, the shielded Cinema can be placed directly on it (see figure 3). The Cinema is equipped with nonskid material underneath to prevent vibration and to keep it from scratching the top of your television. Please see the “Cinema Pad Installation” section below for more details.
On the Wall
An optional adjustable mount is available allowing you to mount the Cinema on the wall or ceiling without locating a stud (see figure 4). Contact your dealer for details.
On the Floor
Placing the Cinema on the floor may position it too low to blend with the front speakers. The use of a stand that positions the Cinema at the bottom of the screen may be a good solution (see figure 5). However, if placing the Cinema on the floor is the best arrangement for your system, the optional adjustable mount will allow for tilting towards the listening position. Contact your dealer for details

Cinema Pad Installation

If not using the optional Cinema adjustable mount, we have provided protective pads to protect the surface the Cinema will be placed on. Follow the instructions below to properly adhere the pads to the bottom of the Cinema (see figure 2). To prevent slipping it is important that the Cinema be used on a level surface. If the Cinema is being used on a tilted surface we recommend use of the optional adjustable mount.
Cinema Pad Installation Instructions:
1. Turn the Cinema upside down and set it on a soft towel.
2. Place the protective pads on the Cinema to determine their placement.
3. Remove white backing being careful not to peel the adhesive layer off.
4. Line up the holes in the pads with the holes in the bottom of the Cinema and carefully apply.
