PERATION

Congratulations! You have invested in one of the world’s

premier loudspeaker systems.

The MartinLogan CLS IIz 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 result of cumulative technology gleaned from previous

research and development projects, the CLS IIz represents the

latest developments in electrostatic loudspeaker technology.

The materials in your new CLS IIz speakers are of the highest

quality and will provide years of enduring enjoyment and

deepening respect. All wood pieces are constructed from

selected hardwoods. They are grain and color matched and

finally hand finished.

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 con-

structed and insulated, as much as 200 watts of continuous

power has driven the CLS IIz’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 CLS IIz speakers and the

philosophy applied to their design. A clear understanding

of your speakers will insure that you obtain maximum per-

formance 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 CLS IIz’s use an internal power

supply to energize their electrostatic cells with high-volt-

age DC, they must be connected to an AC power source.

For this reason they are provided with the proper IEC standard

power cords. These cords should be firmly inserted into the

AC power receptacles on the rear connection panel of the

speakers, then to any convenient AC wall outlet. The CLS IIz’s

integrate 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 CLS IIz speakers are wired for the power service sup-

plied 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 CLS IIz speakers 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 a CLS IIz speaker if opera-

tion 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.
