Important news from DPA Microphones, a brand distributed in Italy by RCF: the 4098 gooseneck microphone model has been updated to DPA’s CORE technology, fulfilling a further development of its already high potential.
The gooseneck 4098 microphone, thanks to the recent update, joins the other CORE products by DPA, thus offering minimal distortion throughout the dynamic range, increasing the clarity of the audio and further improving the already remarkable performance of the sound.
An ideal model for both podium and conference rooms, DPA 4098 CORE now becomes a more than suitable solution for all applications where high speech intelligibility is essential. For example, let’s think about the growing need to organise remote video conferences and meetings: social distancing means the need for greater audio clarity, so that physical distancing between people does not result in difficulty in understanding.
DPA’s CORE technology
CORE is the amplification technology developed by DPA microphones to extend the frequency response, minimise distortion and extend the dynamic range of microphones. Originally created for the lavalier and headset models, CORE proved to be a winning technology, so much so that it was subsequently extended to many other microphones, which further demonstrated its effectiveness.
Furthermore, by increasing the dynamic range of the microphones, CORE technology actually extends the application possibilities of each model equipped with it. This is why the update to this technology of the 4098 model will allow the voice of the speakers, in a conference or sharing session, to reach the listeners in a lively and effective way, as if there were no distances to overcome and the speaker was right in front of the listener.
The ‘new’ DPA 4098 model
At this point, we draw a new identikit of the 4098 microphone in its CORE version. Thanks to the contribution of this technology, the microphone is now able to capture a wider dynamic range, so that the THD (Total Harmonic Distortion) at 1% is now lifted with 8 dB to 133 dB SPL. THD is the overall harmonic distortion value, which measures the introduction into an equipment of a disturbing noise on an audio signal. The main cause of THD, very briefly, is the structural change of the input signal in a device (for example a microphone): the input frequency can be altered, which generates new frequencies considered as noise. This is why THD is a very important datum when evaluating the quality of an audio capture device, which should only send out the ‘original’ frequencies of the input signal, without modifications (ie. distortions.)
Even if the harmonic distortion of a device is not a universally codified parameter, what interests us is to evaluate the reduction of its impact on the DPA 4098 model after its ‘transition’ to CORE technology. The microphone is therefore now more suited to the installation market, offering clearer, more transparent and natural sound and being able to handle extremely high SPL before clipping, which allows it to provide very high speech intelligibility regardless of the type of speaker, which offers an engraved and loud sound or with a soft and suffused tone.
With linear response, low distortion and an extremely wide dynamic range, the DPA 4098 CORE microphone is designed to perform well even in the toughest of environments, from conference rooms to places of worship, from council and parliamentary rooms to school and corporate applications.
DPA 4098 CORE is available in a variety of configurations. All that remains is to take a look at the DPA website, or the Italian distributor RCF, to get more information and… choose the model and configuration. And after that, happy listening everyone!
