FOR EQUIPMENT THAT CONNECTS TO THE POWER MAINS
CAUTION: If the power cord of the device is equipped with an earthing contact, then it must be connected to an outlet with a protective ground. Never deactivate the protective ground of a power cord.
. If the equipment has been exposed to strong fluctuations in temperature (for example, after transport), do not switch it on immediately. Moisture and condensation could damage the equipment. Do not switch on the equipment until it has reached room temperature.
Before connecting the equipment to the power outlet, first verify that the mains voltage and frequency match the values specified on the equipment. If the equipment has a voltage selection switch, connect the equipment to the power outlet only if the equipment values and the mains power values match. If the included power cord or power adapter does not fit in your wall outlet, contact your electrician.
Do not step on the power cord. Make certain that the power cable does not become kinked, especially at the mains outlet and/or power adapter and the equipment connector.
When connecting the equipment, make certain that the power cord or power adapter is always freely accessible. Always disconnect the equipment from the power supply if the equipment is not in use or if you want to clean the equipment. Always unplug the power cord and power adapter from the power outlet at the plug or adapter and not by pulling on the cord. Never touch the power cord and power adapter with wet hands.
Whenever possible, avoid switching the equipment on and off in quick succession because otherwise this can shorten the useful life of the equipment.
IMPORTANT INFORMATION: Replace fuses only with fuses of the same type and rating. If a fuse blows repeatedly, please contact an authorised service centre.
To disconnect the equipment from the power mains completely, unplug the power cord or power adapter from the power outlet.
If your device is equipped with a Volex power connector, the mating Volex equipment connector must be unlocked before it can be removed. However, this also means that the equipment can slide and fall down if the power cable is pulled, which can lead to personal injuries and/or other damage. For this reason, always be careful when laying cables.
Unplug the power cord and power adapter from the power outlet if there is a risk of a lightning strike or before extended periods of disuse.
CAUTION: Never remove the cover, because otherwise there may be a risk of electric shock. There are no user serviceable parts inside. Have repairs carried out only by qualified service personnel.

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electrical shock.
The exclamation mark within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance instructions.
CAUTION – HIGH VOLUME LEVELS WITH AUDIO PRODUCTS!
This equipment is intended for professional use. Therefore, commercial use of this equipment is subject to the respectively applicable national accident prevention rules and regulations. As a manufacturer, Adam Hall is obligated to notify you formally about the existence of potential health risks.
Hearing damage due to high volume and prolonged exposure: When in use, this product is capable of producing high sound-pressure levels (SPL) that can lead to irreversible hearing damage in performers, employees, and audience members.
For this reason, avoid prolonged exposure to volumes in excess of 90 dB.
To prevent possible hearing damage, avoid listening at high volume levels over long periods of time.
Even exposure to short bursts of loud noise can result in hearing loss. Please keep the volume constantly at a comfortable level.

INTRODUCTION

Introduction
The LD Systems CWMS 42 and CWMS 52 are elegant wall speakers with 2-way technology that feature a frequency response up to 20 kHz and high speech intelligibility. The speakers are designed for a wide scope of applications, providing a discreet sound in hotels, restaurants, bars, lounges, training and conference rooms, shopping centres and at home. The LD Systems LD CWMS 42 and CWMS 52 are offered in white and black versions (LDCWMS42W, LDWMS52W, LDCWMS42B, LDCWMS52B).
For ELA systems, all models are also available as 100 Volt versions (LDCWMS42W100V, LDCWMS42B100V, LDCWMS52W100V, LDCWMS52B100V) with 5 connection values (1.25 W / 2.5 W / 5 W / 10 W and 8 Ohm, or 2.5 W / 5 W / 10 W / 20 W and 8 Ohm).

CONNECTIONS, CONTROLS, DIMENSIONS AND MOUNTING

Distance between holes in the wall bracket (hole centre to hole centre)
LDCWMS42: 146 mm
LDCWMS52: 169 mm
A suitable current and temperature protect device should be used for the end- product power amplifier as overload and short circuits could cause audio transformer burnout and ignite.
WALL BRACKET
The speakers can be mounted using the wall bracket either horizontally or vertically. The mount features multiple suspension points, and is thus universally usable. Remove the holder from the speaker by releasing the two thumbscrews (figure A) on the top and bottom. Mount the wall bracket onto a suitable place on the wall or ceiling using suitable mounting hardware, and ensure a secure hold. Now mount the speaker using the two thumbscrews onto the wall bracket and adjust the angle as desired.
SCREW TERMINALS FOR SPEAKER CABLES (8 OHM SPEAKERS)
Connect the positive pole (+) of the speaker cable coming from the amplifier to the red screw terminal (+), and the negative pole (-) of the speaker cable coming from the amplifier to the black screw terminal (-). When connecting multiple speakers in parallel to a power amplifier, please be sure to have the same polarity, minimum impedance (power amplifier) and total load (speakers). For example: 2 speakers with 30 W of power and an impedance of 8 ohms each, when connected in parallel produce a total power of 60 W and a total impedance of 4 ohms. Therefore, a channel of the power amplifier with a power of at least 60 W at 4 ohms is required and must therefore also be stable at 4 ohms (see figure below).

2 SCREW TERMINALS FOR SPEAKER CABLES (100 V SPEAKERS WITH BUILT-IN TRANSFORMER)

The speaker is equipped with a 5-way switch (figure B), which allows you to set the desired connection value.
IMPORTANT: Make sure that the setting of 8 ohms is used nly in connection with a low-impedance speaker amplifier (otherwise equipment damage may occur!). After selecting one of the 4 connection values for 100 V systems on the B switch with a suitable tool, connect the 100 V connection of the speaker cable coming from the amplifier to the red screw terminal (+), and the COM connection (C) of the peaker cable coming from the amplifier to the black screw terminal (-). For the parallel connection of multiple 100 V speakers, please use the same type of speaker and make sure they are all of the same polarity. The output power must be at least the sum of the connection values of the connected speakers. For example: 5 speakers with 10 W of power and an impedance of 8 ohms each, when connected in parallel produce a total power of 50 W (see figure below).
