Frequently Asked Questions - NM250A Montarbo

How to connect a microphone to the NM250A?

Use the MIC input with an XLR or Jack connector. Press the Line/Mic switch to set it to 'mic' position (pressed in). Adjust the volume with the VOL control.

Can I chain multiple NM250A speakers?

Yes, use the LINK output (XLR) of the first speaker to the MIC input of the next. Ensure the Line/Mic switch on each speaker is in 'line' position (raised) unless you are connecting a microphone directly.

What does the LED level meter mean?

The indicator shows the output level: if it never lights, the signal is below maximum power; if it flashes occasionally, you are close to the limit; if it stays lit continuously, there is a risk of saturation (clipping).

How to avoid clipping on the NM250A?

Set the mixer input levels so channel indicators do not exceed 0 dB. Adjust the speaker volume with the VOL control so the level meter does not light continuously. Input sensitivity is -10 dBu.

What is the required power supply voltage?

The voltage must match that indicated on the rear panel (e.g., 230 V or 110 V depending on model). Use exclusively the supplied power cable with grounding.

Can I use the NM250A outdoors?

Yes, but protect it from rain and bad weather. Avoid direct sunlight and dusty or humid environments.

How to clean the speaker?

Use a soft brush or compressed air to dust the grille and baffle. Never use alcohol, detergents, or solvents.

What to do if the fuse needs replacing?

Introduction

The NM250A is an active, bi-amplified, high-performance system that combines the high power and sound pressure levels typical of much larger and heavier professional systems with the sonic accuracy and precision of hi-fi systems, all in a compact package that is incredibly easy to transport and fast to set up. Designed for small concerts, press conferences, and talk shows, the NM250 gives you the fidelity, dynamics, and versatility you expect from a reference monitor system for your home studio.

The cabinet's shape allows for vertical (also mounted on a speaker stand) or horizontal placement, even in restricted spaces, enhancing its great flexibility of use.

High-quality components, custom designed to our specifications:

- 8" high-efficiency woofer,

- 1" compression driver loaded by a 90° H x 60° V horn (integrated in the cabinet's body).

2 class AB MosFet power amplifiers (200 + 50 W)

Each one of the two power amplifiers is controlled by an active processor, designed to optimize the linearity of the frequency response as well as the working performance of the systems and is fitted with our exclusive transducers protection circuitry.

Description

A 1" compression driver loaded by a 90° x 60° horn. B 8" high efficiency woofer. C Injection moulded polypropylene cabinet. E Perforated steel grid. F Tuning ports. G Transport handle.

H Control and connection panel. I Speaker stand adaptor with safety lock. L Internal threaded inserts (M8) for brackets. M Mating feet and cavities for cabinet stacking.

Construction and components conform to the highest professional standards for maximum reliability.

Control and connection panel

1 MIC: balanced input, with adjustable sensitivity (microphone -40dBu / 2kOhms or line -10dBu / 20kOhm), dotted with a Neutrik Combo ^® connector which accepts both 3 pin XLR and jack plugs.

See 'connectors' and 'connections' at pages 25 and 26, and 'applications at pages 27, 28 and 29.

2 LINE/MIC: input sensitivity switch (mic when pushed in). The switch is factory set in the 'line' position (button up) for the most common applications (connection to a mixer or to other active systems). If you want to connect a microphone directly to the input you must push the button to 'mic' (as input and output of the NM250A are connected in parallel and carry the same signal, should the output be connected to another NM250A the line/mic switch of the latter should also be set in the same way of the other).

3 LINK: balanced output, (in parallel with the input), using a 3 pin XLR connector. It allows for easy parallel connection of other NM250A or active systems.

See 'connectors' and 'connections' at pages 25 and 26, and 'applications at pages 27, 28 and 29.

4 Peak led indicator. The PEAK indicator is of great help to get an idea of the output level:

- if it never blinks, this means that the system is still below its power limits.

- Occasional blinking of this LED indicates that the working condition is near the maximum level, yet the musician's experienced ear still continues to be the best judge of the signal quality.

5 VOL: This is the master volume control.

Adjusts the input levels of the 2 built-in power amplifiers to adapt them to the output level of the mixer. It also allows adjusting the speaker volume when this system is used in parallel with others. Typical operating setting is at maximum position (sensitivity -10dBu). When a microphone is connected to the input, this control must be adjusted to reach the desired volume.

6 HIGH / LOW: 2-band equalizer. It allows changing the response curve of the system depending on the requirements of each different application. This enables optimizing the NM250A's working condition for each specific requirement, whether it is used, for example, in a conference hall, on stage for monitoring, and many other situations.

Note: To obtain a flat response, it is advisable to set both the HIGH and LOW controls to their mid settings.

7 POWER /0 - I: Mains power on/off switch.

8 Mains power cord socket (with built-in fuse).

Use only the factory supplied mains cable or a suitable cable with a ground connection and marked with the safety approvals valid in the country of use.

When installing, make sure that it is easy to get to this connector and to the mains plug.

Important!

Product care and maintenance:

• Never expose the enclosure to heat sources (heaters or other products that produce heat).
• Never place burning candles or other sources of open flame on top of the device.
• Never expose the enclosure to direct sunlight, excessive vibrations, or mechanical shocks.

- Avoid operating and storing the enclosure in damp or dusty places: this may lead to malfunctions and premature degrading of specifications.

- Avoid using the enclosure close to strong sources of electromagnetic interferences (e.g. video monitors, high power electrical cabling). This may lead to degradation of audio quality.

- When setting up the system outdoors, be sure to protect it against rain.

- Care should be taken so that objects do not fall and liquid is not spilled onto the enclosure. In public events, don't let people, musicians, technicians, or anyone put glasses, cups, ashtrays, or cigarettes on the enclosure.

• Always leave the protective grid mounted on the enclosure.

- Use a soft brush or a jet of air to clean the enclosure. Do not use alcohol, solvents, or detergents.

- Take care of your connector cables. Make sure that they are not damaged, knotted, or twisted.

- Do not force connectors and controls.

- Make sure the mains power switch is off ('0') before starting any connection.

- As long as it is plugged in, there can be potentially dangerous electrical potentials inside the device. So, before undertaking any sort of maintenance work, etc., always make sure it has been unplugged from the mains socket.

Power supply connection:

• Make sure the mains power switch is off ('0').
• Check that the mains voltage corresponds to the voltage indicated on the panel, under the mains socket.
• Use only the factory supplied mains cable or, if a different plug style is needed, a suitable cable with a ground connection and marked with the safety approvals valid in the country of use.
• Leave enough room to get to the mains power socket and the mains connector on the back panel.

As long as it is plugged in, there can be potentially dangerous electrical potentials inside the device, even when the mains switch is in the '0' (off) position and the power indicator is off. So, before undertaking any sort of maintenance work, etc., always make sure it has been unplugged from the mains socket.

Connection to the mixer:

• Always use only heavy gauge, high quality SHIELDED cables (signal cables).
• Always make sure that the mixer and the powered enclosures are switched off before connecting them. This will avoid annoying noises and signal peaks, which can also be dangerous for the enclosures themselves.

• Always make sure that the 'Line/mic' switch is up. - If the mixer has XLR balanced outputs: use standard balanced XLR connectors. - If the mixer has XLR unbalanced outputs: in this case, unless using a Montarbo mixer, make sure that the XLR outputs on the mixer are unbalanced to IEC 268 standard: pin 1 = GND, pin 2 = HOT, pin 3 = GND. - If the mixer has JACK balanced outputs (stereo jacks): it is possible to use stereo Jack-stereo Jack cables or stereo jack-XLR adapters, wired according to IEC 268: pin 1 = ground (sleeve), pin 2 = tip, pin 3 = ring. - If the mixer has JACK unbalanced outputs (mono jacks): use suitable Jack-XLR male adapters unbalanced according to IEC 268: pin 1 = ground, pin 2 = tip, pin 3 = ground

See 'connectors' at page 25.

Parallel connection of two or more systems:

- Always make sure to use only heavy gauge, high quality SHIELDED cables. Connect the LINK OUT of the first NM250A to the input (MIC) of the second one (make sure that the 'Line/mic' switch is up), the LINK OUT of the second system to the input of the third one, and so on.

See 'connection example' at page 26.

Output sensitivity and clipping.

Every amplified speaker system is characterized by a value of input sensitivity. The sensitivity is defined as the value of the amplifier's input signal that will result in maximum power output. An increase in input signal over that threshold will result, not in increased power, but in a distortion phenomenon called 'clipping' (output stage saturation).

In this condition, the speaker will operate improperly. The diaphragm will exceed its excursion limits, and the voice coil will overheat beyond its thermal limits, resulting in overheating and premature failure. The active processors will help in avoiding clipping, by reducing the amplifier gain and thus the input sensitivity, but this type of protection may be overridden in very extreme conditions. What the active processor cannot modify is a signal that is distorted before getting to the active speaker's input.

The effects of this type of signal are the same as described above.

How to avoid clipping

The simplest way to avoid clipping is to check each level in the signal chain. Start from each input channel of the mixer and adjust the gain control and the equalizer's controls so that the PFL meter will never (or only occasionally) indicate more than 0dB. In simpler mixers, check that the 'clip' or 'peak' indicator is always off, or blinks only occasionally.

If these levels are exceeded, reduce the channel's input gain. Once the desired mix is obtained, adjust the output level so that it never exceeds the active speaker's or the power amplifier's input sensitivity, as displayed on the master output VU-meter. In model NM250A the input sensitivity is -10dBu.
