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!
