Before operating your product, read this manual first and understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.

When Installing the Unit

• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and/or property damage.
• Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket. Doing otherwise may result in the unit falling down and causing personal injury and/or property damage.
• Since the unit is designed for in-door use, do not install it outdoors. If installed outdoors, the aging of parts causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a danger of electric shock.
• Owing to the unit’s size and weight, be sure that at least two persons are available to install the unit. Failure to do so could result in personal injury.
• Do not use other methods than specified to mount the bracket. Extreme force is applied to the unit and the unit could fall off, possibly resulting in personal injuries.
• Use screws that are appropriate for the ceiling’s or wall’s structure and composition. Failure to do so may cause the unit to fall, resulting in personal injury.
• Ensure that all screws are securely tightened. If they are not tightened or firmly secured after installation, the unit could fall down, possibly resulting in personal injury.
• Use the specified mounting bracket in combination. Doing otherwise may cause the unit or component to fall off, resulting in personal injury.
• Do not mount the unit in locations exposed to constant vibration. The mounting bracket can be damaged by excessive vibration, potentially causing the unit to fall, which could result in personal injury.

When Installing the Unit

• When unpacking or installing the unit, be sure to handle it with two or more persons. Falling or dropping the unit may cause personal injury.
• Avoid touching the unit’s sharp metal edge to prevent injury.
• To avoid electric shocks, be sure to switch off the amplifier’s power when connecting speakers.

When the Unit is in Use

• Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.
• Make sure that the volume control is set to minimum position before power is switched on. Loud noise produced at high volume when power is switched on can impair hearing.
• Do not operate the unit for an extended period of time with the sound distorting. This is an indication of a malfunction, which in turn can cause heat to generate and result in a fire.

DIMENSIONAL DIAGRAM

INPUT TERMINAL SECTION

• As the Speakon connector is internally connected in parallel to the screw terminal as shown below, you can use either of the two.
• The usable connector (on the cable end) that matches the NEUTRIK NL4MP Speakon is NEUTRIK NL4FX Speakon.
• Input terminal connection diagram is as shown below.

IMPEDANCE CHANGE

To change the impedance, use a standard screwdriver to rotate the rotary switch on the speaker’s rear panel to select the desired input power.
This switch is factory-preset to 670 Ω.

Note

When using a high-impedance amplifier, never select 8 Ω, as this will damage the speaker and the amplifier.
Be sure to turn the rotary switch to 8 Ω when using a low-impedance amplifier.

ABOUT THE INPUT OVERLOAD PROTECTION CIRCUIT

The speaker system has a built-in input overload protection circuitry. If an excessive input signal is applied to the speaker, the protection circuitry is activated and cuts off the signal input to the tweeters. A sudden drop of the sound volume level during speaker operation indicates that the protection circuitry has been activated. In such a case, reduce the amplifier volume and wait. The protection circuitry is automatically reset after approximately 10 seconds. After the circuitry is reset, set the volume at a lower level than before.

Note

This input overload protection circuitry does not completely protect the speaker component. Depending on the nature of the excessive input signal applied to the speaker, there may be damage to the speaker components before protection circuitry can operate. Also, if the excessive input signal is applied to the speaker for extended periods of time, the protection circuitry may be damaged and will not recover. Take special care that the excessive input signal is not applied to the speaker during use.

FREQUENTLY ASKED QUESTIONS

Are line array speakers good?

Column speakers and vertical line arrays typically offer good vertical coverage control at the expense of a fixed horizontal. Point source speakers may perform better than a line array in this situation, depending on the aspect ratio of the room and the nature of the horizontal reverberation in the area.

What is an array speaker?

A line array is just a group of speakers that all operate in the same frequency range that are arranged in a line, usually vertically. Since the speakers are positioned at somewhat different vertical angles, they may cover a larger area than a single speaker could.

What are the 4 types of speakers?

Traditional loudspeakers, in-wall/ceiling speakers, soundbars, and subwoofers are the four basic speaker kinds now available in homes. Each variety of speaker has a distinct function and is advantageous in certain contexts.

What is the highest watts in a speaker?

This amazing speaker has a maximum sound output level of 165 dB. As simple as it may sound, the manufacturer of this speaker claims that its primary purpose was to produce noise. This speaker has a 30,000-Watt output and a 165dB sound level, which might be harmful to your health.

What are line array speakers for?

A line array speaker system is often made up of a series of passive or active (powered) speakers that are suspended from a truss, winch, or beam on either side of a stage in order to provide the audience with loud, clear, and high-quality sound.

Why do line arrays sound different?

Lowering the level from the lower cabinets will give a lower sound-pressure level to the front of the audience since those rows are considerably closer to the lower cabinets of the array than they are to the top cabinets.

When would you use a line array?

A line array system projects sound in a more cylindrical-like shape. Because of this, much less sound energy is vertically projected (to the ceiling and floor). Reduced vertical dispersion is advantageous for two reasons.

Is 2 way or 4-way speakers better?

Two parts, a tweeter for high frequency and a mid-range, make up a two-way speaker. The 4-way speaker is slightly better for high range sound than the 2 way since it has a bass and a mid-range component in addition to 2 tweeters, but it is not significantly better overall.

Is 20 watts louder than 10 watts?

The 20-watt amp has twice the power of the 10-watt amp, although this power increase only results in a 3 dB SPL increase. A 20W amplifier will sound substantially louder than a 10W amp, but it won’t sound twice as loud because an increase of 10dB is required to sound “twice as loud.”

How many watts is loud enough?

Most people won’t need more than 50 watts, yet Denon’s most affordable receiver, the AVR-1513, has a 110 watts per channel rating.

How many watts do you need for good sound?

A lot depends on how well you listen and how well you speak. If your speakers are 90 dB efficient and you enjoy listening to loud, uncompressed music, 200 Watts should be more than plenty for you. 50 Watts is plenty if all you listen to is jazz and light classical music and you don’t expect them to rock the house.

What are the drawbacks of linear array?

An array’s capacity for storing elements should be predetermined. As a static structure, an array (which means the array is of fixed size). The array’s size cannot be changed after it has been declared.

Do you need tweeters with 4-way speakers?

Any audio system that wants to produce high frequencies up to the upper limit of human hearing needs tweeters. Any audio system without them is merely inadequate and constrained. Installing tweeters will improve the overall sound quality and help the music have a sense of presence and space.
