Frequently Asked Questions - MQ100L RCF

How do I set the power tap for a 100 V line?

Use a screwdriver to rotate the rear panel rotary switch to the desired power: 5 W, 10 W, 20 W, or 40 W. Never set to 16 Ω when connected to a constant voltage line.

What impedance should I use for low impedance connection?

Set the rotary switch to the 16 Ω position. The loudspeaker can handle up to 60 W musical power (40 W RMS) at 16 Ω.

Can I use this loudspeaker outdoors?

It is designed for indoor use. Outdoor use is only allowed if the loudspeaker is protected from rain, humidity, and dust. The enclosure is not weatherproof.

How do I mount the MQ 100L to a wall?

Fix the wall-mount support vertically using four M4 dowels. Attach the mounting bracket to the rear panel with the included self-tapping screws. Then slide the column onto the support and tighten the central screw. Choose from three bracket lengths for 0°, 5°, or 10° tilt. Use the safety steel wire for extra security.

What is the vertical coverage angle?

The vertical coverage is 60° with an asymmetric pattern: 20° upward and 40° downward. The dispersion axis is already angled 10° downward, so tilting the column excessively is unnecessary.

How do I connect the loudspeaker to a 100 V line?

Connect the amplifier's 100 V output (+) to the '+' terminal and the common (0 V / COM) to the '-' terminal. Set the rotary switch to the desired power (5-40 W). Ensure the total connected power does not exceed the amplifier's rated power.

What is the maximum cable wire size for the Euroblock connector?

The Euroblock terminal accepts a maximum wire cross-section of 2.5 mm².

Is this speaker suitable for speech reinforcement?

Yes, it is designed for both speech and music. The 3-way column provides natural hi-fidelity sound and high intelligibility, especially in acoustically critical environments with long reverberation times.

How do I clean the loudspeaker?

Do not use solvents, alcohol, benzene, or other volatile substances. Clean the external parts with a dry or slightly damp cloth. Avoid letting any liquid enter the enclosure.

What safety precautions should I follow during installation?

Always disconnect the amplifier before connecting or installing the speaker. Ensure the supporting wall can bear the weight (4.2 kg). Use the provided safety steel wire and follow all local electrical regulations. Never expose the speaker to rain or moisture.

SAFETY AND OPERATING PRECAUTIONS

1. All the precautions, in particular the safety ones, must be read with special attention, as they provide important information.
2. Loudspeaker lines (amplifier outputs) can have a sufficiently high voltage (i.e. 100-70 V) to involve a risk of electrocution: never install or connect this loudspeaker when the line is alive.
3. Make sure all connections have been made correctly and the loudspeaker input voltage (in a constant voltage system) or its impedance is suitable for the amplifier output.
4. Protect loudspeaker lines from damage; make sure they are positioned in a way that they cannot be stepped on or crushed by objects.

5. Make sure that no objects or liquids can get into this product, as this may cause a short circuit.

6. Never attempt to carry out any operations, modifications or repairs that are not expressly described in this manual.

Contact your authorized service centre or qualified personnel should any of the following occur:

The loudspeaker does not function (or works in an anomalous way).

The cable has been damaged.

Objects or liquids have got into the unit.

The loudspeaker has been damaged due to heavy impacts or fire.

1. Should the loudspeaker emit any strange odours or smoke, remove it from the line after having immediately switched the amplifier off.

2. Do not connect this product to any equipment or accessories not foreseen.

For suspended installation, only use the dedicated anchoring points and do not try to hang this loudspeaker by using elements that are unsuitable or not specific for this purpose.

Also check the suitability of the support surface to which the product is anchored (wall, ceiling, structure, etc.), and the components used for attachment (screw anchors, screws, brackets not supplied by RCF etc.), which must guarantee the security of the system / installation over time, also considering, for example, the mechanical vibrations normally generated by transducers.

1. RCF S.p.A. strongly recommends this product is only installed by professional qualified installers (or specialised firms) who can ensure a correct installation and certify it according to the regulations in force.

The entire audio system must comply with the current standards and regulations regarding electrical systems.

1. There are numerous mechanical and electrical factors to be considered when installing a professional audio system (in addition to those which are strictly acoustic, such as sound pressure, angles of coverage, frequency response, etc.).

IMPORTANT NOTES

WARNING

1. Hearing loss

Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different from person to person and depends on the duration of exposure.

To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices.

When a transducer capable of producing high sound levels is being used, it is necessary to wear ear plugs or protective earphones.

See the technical specifications in the instruction manual for the maximum sound pressure the loudspeaker is capable of producing.

1. To ensure a correct sound reproduction, loudspeaker phase is to be respected (loudspeakers are connected respecting the amplifier polarity). This is important when loudspeakers are installed adjacent one another, for instance, in the same room.

2. To prevent inductive effects from causing hum, noise and a bad system working, loudspeaker lines should not be laid together with other electric cables (mains), microphone or line level signal cables connected to amplifier inputs.

3. The loudspeaker cable shall have wires with a suitable section (twisted, if possible, to reduce inductive effects due to surrounding electro-magnetic fields) and a sufficient electrical insulation. Refer to local regulations since there may be additional requirements about cable characteristics.

4. Install this loudspeaker far from any heat source.

5. When connect to its low impedance input, do not overload the loudspeaker with too much power.

6. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external parts of this product.

DESCRIPTION

MQ 100L (/ MQ 100L-W) is a 3 way column loudspeaker providing natural hi-fidelity sound of both speech (to improve the intelligibility) and music, suitable for sound system having fixed loudspeakers where the environment is acoustically critical or there are architectural constraints.

The wide horizontal coverage angle (180°) and the 60° vertical dispersion allow the correct sound reproduction in a wide space, in order to limit feedbacks and improve the sound directivity (important in halls having a long reverberation time).

THE 60° VERTICAL DISPERSION IS ASYMMETRIC: IT IS THE DIFFERENCE BETWEEN 20° UPWARDS AND 40° DOWNWARDS. THE VERTICAL DISPERSION AXIS IS IN FACT ALREADY ANGLED 10° DOWNWARDS, MAKING IT UNNECESSARY TO TILT THE SOUND COLUMN EXCESSIVELY.

MQ 100L IS EQUIPPED WITH:

• 4 rubber surround 3.5" woofers
• 2 cloth coated 0.75" dome tweeters.

Mounting accessories are included. These have been studied to keep the column as close as possible to the wall and simplify its installation. Its tilt angle can be chosen among 0^-5^-10^ .

It includes a transformer inside for the connection to (100 - 70 V) constant voltage lines, yet it can also be set to 16 Ω (low impedance connection).

The power / mode selection is made by means of the rear panel rotary switch.

LOUDSPEAKER RMS POWER IS:

a. 40 - 20 - 10 - 5 W (selectable), if connected to a 100 V constant voltage line.

b. 20 - 10 - 5 - 2.5 W (selectable), if connected to a 70 V constant voltage line.
c. Max. 60 W on low impedance (16 Ω).

Its body is made of self-extinguishing (HB level) high density polystyrene.

AVAILABLE IN 2 COLOURS:

• Black MQ 100L
• White MQ 100L -W.

SETTING (REAR PANEL ROTARY SWITCH)

Use a screwdriver to select.

OFF position: the loudspeaker is disabled (muted).

a. 100 V (/ 70 V) constant voltage line Select the desired power (referred to a 100 V line) among 5 – 10 – 20 – 40 W.

b. Low impedance input Set the rotary switch to the 16 Ω position.

When using a 70 V line, the power is halved: 2.5 - 5 - 10 - 20 W.

WARNING: NEVER SET THE 16 Ω POSITION WHEN THE LOUDSPEAKER IS CONNECTED TO A 100 / 70 V CONSTANT VOLTAGE LINE.

CONNECTION

WARNING: loudspeaker connections should be only made by qualified and experienced personnel having the technical know-how or sufficient specific instructions (to ensure that connections are made correctly) in order to prevent any electrical danger.

To prevent any risk of electric shock, do not connect loudspeakers when the amplifier is switched on. Before turning the system on, check all connections and make sure there are no accidental short circuits. The entire sound system shall be designed and installed in compliance with the current local laws and regulations regarding electrical systems.

The input connector is on the column rear panel (picture 5).

Connect the line positive wire (coming from the amplifier output usually marked '100 V', '70 V' +' or 'a') to the '+' loudspeaker terminal.

Connect the line negative wire (coming from the amplifier output usually marked '0', '-', 'COM' or 'b') to the '-' loudspeaker terminal.

NOTES ABOUT CONSTANT VOLTAGE SYSTEMS

• The loudspeaker input voltage (Vd) shall correspond to the amplifier output voltage (Va).
• The sum of nominal power values (Pd x n) of all loudspeakers connected to the line shall not exceed the amplifier power (Pa).
• Make sure all loudspeakers are connected in phase to ensure a correct sound reproduction.

Pa = Amplifier power

Pd = Speaker power

n = Number of speakers

Vd = Speaker input voltage

Va = Amplifier output voltage

NOTES ABOUT LOW IMPEDANCE CONNECTIONS

• The total loudspeaker impedance must not be lower than the amplifier output IMPEDANCE. NOTE: A LOUDSPEAKER TOTAL IMPEDANCE EQUAL TO THE AMPLIFIER OUTPUT ONE PERMITS TO GET THE MAXIMUM DELIVERABLE POWER (BUT AN HIGHER LOUDSPEAKER IMPEDANCE ENTAILS LESS POWER).
• The total loudspeaker power shall be adequate for the maximum deliverable power of the amplifier.
• The loudspeaker line shall be as short as possible (for long distances, it may be necessary to use cables with large cross-section wires).

ADDITIONAL NOTES

• Always use cables having wires with an adequate cross-section, considering the cable length and the total loudspeaker power.
• Loudspeaker lines must be kept separated from mains cable, microphone cables or others, in order to avoid inductive phenomena may cause hum or noises.
• Use loudspeaker cables having twisted wires to reduce hum caused by inductive effects due to coupling with electromagnetic fields.
• NEVER set the rotary switch to the 16 Ω position when the loudspeaker is connected to a (100 – 70 V) constant voltage line.
