INSTALLATION IN BRIEF

We know you are eager to hear your new CLS IIz loudspeakers, 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 attain the greatest possible performance from this most exacting transducer.

If you should experience any difficulties in the setup or operation of your CLS IIz speakers, please refer to the Room Acoustics, Placement or Operation sections of this manual.

Should you encounter a persistent problem that cannot be resolved, please contact your authorized MartinLogan dealer. They will provide you with the appropriate technical analysis to alleviate the situation.

WARNING!

•Hazardous voltages exist inside—do not remove cover

•Refer servicing to a qualified technician •To prevent fire or shock hazard, do not

expose this module to moisture •Turn amplifier off and unplug speaker

should any abnormal conditions occur •Do not operate if there is any visual

damage to the electrostatic panel element •Do not over drive speaker beyond its rated power

Step 1: Unpacking

Remove your new CLS IIz speakers from their packing. Carefully lean one transducer against a wall with the curved portion of the speaker resting against a wall.

Step 2: Connection

Do not connect the AC power cords to your electronics modules yet!

Move the electronics module close to the transducer frame. Firmly insert the high voltage connector from the electro- static transducer into the matching socket near the front of the electronics module.

Step 3: Attach Electronics Module

Now attach the electronics module to the wooden trans- ducer frame using the Allen head cap screws and finish

washers. Please start the cap screws by hand to prevent stripping then tighten with the provided Allen head tool.

Step 4: Install the Adjustable Feet

Attach the enclosed feet to the bottom of the wooden transducer frame and electronics by threading into the metal inserts located in the bottom of each. These feet allow you to adjust the vertical ‘tilt’ of the speaker system.

Step 5: Placement

Place each CLS IIz at least two feet from any wall and angle them slightly toward your listening area. This is a good place to start. Please see the Placement section (pages 6–7) of this manual for more details.

Step 6: Power Connection (AC) (see warning) MartinLogan speakers require AC power to energize their electrostatic cells. Using the AC power cords provided, plug them in first to the AC power receptacle on the rear panel of the speaker, making sure that you have made a firm con- nection, and then to the wall outlet. Please see the Operation section (pages 4–5) of this manual for more details.

Step 7: 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 CLS IIz: 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, you may need to reverse the (+) and (–) leads on one side to bring the system into proper polarity.

Step 8: Listen and Enjoy

Now, you may turn on your system and enjoy!

CLS IIz specifications

The MartinLogan CLS IIz is a sophisticated hybrid electrostatic loudspeaker that exemplifies the brand's commitment to innovation and exceptional audio performance. This model is a continuation of the legendary CLS design, which has garnered a loyal following among audiophiles and music enthusiasts alike.

One of the standout features of the CLS IIz is its electrostatic transducer design. Unlike conventional dynamic speakers that rely on moving coils and cones, electrostatic speakers use a thin, electrically charged diaphragm sandwiched between two stators. This design allows the CLS IIz to produce sound with extraordinary clarity, speed, and precision, making it particularly well-suited for accurately reproducing the nuances of vocal performances and acoustic instrumentation.

The CLS IIz also integrates a new, more advanced version of the brand's Curvilinear Line Source technology. This innovation provides a wider and more consistent sound dispersion pattern, resulting in an expansive soundstage that immerses listeners in their favorite recordings. The speaker’s tall, slender design further enhances this effect, allowing for an impressive imaging capability that places sounds precisely within the listening environment.

Another key characteristic of the CLS IIz is its frequency response. The speaker is capable of reproducing frequencies from an astonishingly low 38 Hz to a remarkable 25 kHz. This wide frequency range ensures that music and audio content are delivered with great depth and richness, fully capturing the lower bass notes while maintaining the sparkling clarity of high-frequency sounds.

In terms of build quality, the CLS IIz features a sturdy yet elegant cabinet that minimizes resonance and vibration, allowing for pure audio reproduction. The speaker's sleek aesthetic is complemented by high-quality finishes, ensuring that it looks as good as it sounds, making it an attractive addition to any audio setup.

Additionally, the CLS IIz boasts versatility in its setup, allowing for positioning flexibility that accommodates various room sizes and acoustic conditions. This ensures that enthusiasts can achieve optimal sound quality regardless of their environment.

In summary, the MartinLogan CLS IIz is a marvel of modern audio engineering that combines cutting-edge technologies with a commitment to high fidelity sound. With its electrostatic design, advanced dispersion capabilities, wide frequency response, and elegant build, the CLS IIz stands as a testament to MartinLogan's dedication to providing an unparalleled listening experience.
