INDICATORS & POSITIONING

Indicators

On the front you will find 2 diodes. These are positioned just above the Dynaudio Logo.

The green power diode indicates speaker on/off status. Green indicates; “power on”.

The second diode has two functions. This will light up orange when the input signal reaches a level where the limiter is activated to

prevent the internal bass amplifier from clipping. And it will light up red when the amplifier gets too hot. At the same time the monitor will be muted, in order to reduce the temperature.

The woofer channel has a built in limiter that protects the woofer unit from too much excursion. It works by reducing the gain of the circuit when a certain threshold level is reached.

Positioning

The BM 5A is designed as a near to mid-field monitor and can be equally well used in both stereo and surround setups. Optimal performance is achieved when positioned 1-3 meters from the listener.

It can be placed on stands or on the meter bridge of a console provided that the meter bridge is sufficiently sturdy. For best results the speakers may be aimed towards the listener in both vertical and horizontal planes.

Note:

Be aware that proper air circulation around the monitor for sufficient cooling is necessary. Also notice that the heat sink is designed to provide maximum cooling when the monitor is positioned vertically.

Protection

The BM 5A monitor has several built in protection systems to reduce the risk of hazard or damage due to overloading.

Both power amplifiers have thermal protection. This activates if a problem should occur, and helps protect both the electronics and the loudspeaker drivers.

There is also a thermal sensor measuring the temperature on the heat sink. An electronic circuit will mute the signal when too high temperature is reached. The protection diode on the front will light up when this happens.

On the tweeter output there is an overload protection to prevent burning the tweeter driver in case of overloading. This circuit will mute the tweeter signal if too much current is fed to the tweeter.

BM 5A specifications

The Dynaudio BM 5A is a highly regarded active studio monitor that has earned a reputation for its exceptional sound quality and precision in professional audio environments. Designed for critical listening, the BM 5A is particularly favored among recording engineers, music producers, and sound designers for its reliable performance and transparency across various audio frequencies.

One of the standout features of the Dynaudio BM 5A is its meticulous engineering, which includes a robust woofer and tweeter system. The monitor is equipped with a 5.1-inch polypropylene woofer that delivers powerful bass response, while the 1.1-inch soft dome tweeter provides smooth and accurate high-frequency reproduction. This combination ensures that the BM 5A can handle a wide range of musical styles and intricate sound mixes, making it a versatile choice for any studio.

The BM 5A comes with built-in amplification, utilizing a Class AB power amplifier that drives both the woofer and tweeter. This onboard amplification is specially tuned to match the speaker drivers, providing an ideal balance between power and fidelity. The result is a dynamic range that allows for both soft and loud passages to be faithfully reproduced without distortion.

Another defining characteristic of the BM 5A is its advanced acoustic design. The cabinet is made from high-quality MDF, which minimizes resonance and contributes to the monitor's overall clarity. Dynaudio also incorporates a rear bass reflex port that enhances low-frequency performance while maintaining tightness and accuracy.

The BM 5A is designed with flexibility in mind, featuring rear panel controls for tailoring the monitor's response to different acoustic environments. This includes adjustments for high and low-frequency levels, enabling users to compensate for various room characteristics and achieve an optimal listening experience.

Additionally, the Dynaudio BM 5A is known for its outstanding transient response, allowing it to capture minute details within a mix. This makes it an invaluable tool for mixing and mastering, where precision is paramount. With its combination of advanced technologies, high-quality components, and a well-thought-out design, the Dynaudio BM 5A stands out as a top choice for professionals seeking an accurate and reliable monitoring solution in the studio.
