CHECKING - SUBWOOFER PLACEMENT

Do not place the subwoofer on these lines quarter or halfway between walls.

Overview

1Main menu, set volume -20 dB

2Main menu, select Bass Management:

120 Hz

3Set Bass Management to “on”

4Check the monitor position using the CD, tracks 30-44

5Go to: Calibrating the subwoofer with the main system.

Test signals on CD

With the monitors you received a CD containing a lot of useful test signals to be used for the set up of the monitors.

Low frequency sweeps

The tracks 30 to 37 contains the following sweep sequences

Track 31:

200

Hz - 20 Hz

Track 32:

160

Hz - 20 Hz

Track 33:

125

Hz - 20 Hz

Track 34:

100

Hz - 20 Hz

Track 35:

80

Hz - 20 Hz

Track 36:

63

Hz - 20 Hz

Track 37:

50

Hz - 20 Hz

Track 38:

40

Hz - 20 Hz

Track 39:

32

Hz - 20 Hz

During the sweeps you will hear short "bleebs" telling when the signal passes one of the ISO center frequencies. There are two “bleebs” every time the frequency passes a whole octave center frequency and one “bleeb” every time the in- between 1/3-octave center frequencies are passed.

Play all the tracks using only the subwoofer.

Mute all other monitors.

Evaluation

In the listening position you should hear the signal smooth and even throughout all frequency sweeps (bearing in mind that the frequency response of the ear is not flat).

If you have a sound level meter this should be set to "LIN" with no frequency weighting. If the meter does not have a LIN position you can use the C-weighting, though the response is attenuated approximately 3 dB at 31.5 Hz and approximately 6 dB at 20 Hz.

In the background reading (page 39) you can find instructions on how alternatively to use a studio microphone if you do not have a sound level meter.

If OK continue to next chapter: Calibrating the subwoofer with the main system.

If not OK you must find new positions for the subwoofer.

pmn specifications

Dynaudio, a company renowned for its high-fidelity audio products, has made significant strides in the field of professional monitoring through its PPM (Professional Precision Monitoring) series. Among the standout models in this series is the Dynaudio PMN (Professional Monitoring Nearfield), which has garnered attention for its outstanding sound quality, precise technical performance, and sophisticated design.

One of the key features of the Dynaudio PMN monitors is their advanced driver technology. Equipped with proprietary drivers, the PMN series employs custom-designed woofers and tweeters that deliver an incredibly accurate frequency response. The woofers utilize a lightweight diaphragm, ensuring that low frequencies are produced with power while maintaining clarity. The tweeters, known for their soft dome design, excel in reproducing high frequencies with exquisite detail and minimal distortion, making the listening experience both immersive and enjoyable.

In terms of design, the PMN monitors boast a sleek and modern aesthetic that fits seamlessly into any studio environment. The cabinet construction employs advanced materials and techniques that minimize resonance, thus reducing unwanted coloration in sound. The unique curved shape of the cabinets is not only visually appealing but also supports optimal acoustic performance by enhancing sound dispersion.

Another notable characteristic of the Dynaudio PMN is its versatility. The monitors are equipped with multiple inputs, allowing for seamless integration into various set-ups, whether in a professional studio or a home listening environment. This flexibility is further complemented by adjustable bass and treble controls, empowering users to tailor the sound profile to their specific requirements.

Dynaudio has also incorporated advanced technologies such as room correction in certain PMN models, which enables precise calibration according to the acoustics of the room. This feature ensures that audio professionals can rely on consistent and accurate sound reproduction regardless of their monitoring environment.

Overall, the Dynaudio PMN series represents a blend of pioneering audio technology, meticulous craftsmanship, and user-focused design. For professionals seeking precise monitoring solutions for music production, film scoring, or any audio-related projects, the Dynaudio PMN monitors provide an exceptional listening experience that stands the test of time. With their stellar performance and innovative features, these monitors have become a top choice for sound engineers, musicians, and audio enthusiasts alike.
