Decibel and Meter – IV

Fig, 1 Before proceeding to analyze the LUFS meter that have defined legal limits and recommendations of use in the production of mix and master audio after years of battles to make music and sounds with the highest values of loudness for the song or audio track that sounds "louder," it’s good to take a … Continue reading Decibel and Meter – IV

Digital Meter The digital meter (fig. 1) are the meter that identifies the output values and the signal input to digital scale used in digital audio equipment (after the A/D converter and before the D/A converter when it comes to analog inputs and outputs and software. Fig. 1 At the hardware level they are such … Continue reading Decibel and Meter – III

Meter Types We said that the meters have been created to facilitate the reading of the voltage circulating in audio equipment so that you know when the signal level is low, high, right, so as not to create distortions, maintain proper dynamic and correctly interface different devices audio. As it regards to the structure of … Continue reading Decibel and Meter – II

Decibel and Meter – I

The Decibel is the logarithmic measure unit used for the sound, but depending on its application has its own scale and reference values. We leave aside for the moment the decibel acoustic (pressure, power, density and loudness) that requires arguments apart and instead concentrate on the scales and measurements in decibels used in analog and … Continue reading Decibel and Meter – I

MAIN TYPES OF CONNECTION Here we see some common types of connection, how to be links for the transport unbalanced signal to the balanced and mixed. It’s represented the signal path from the output to the input of connections, the possible presence of the shield and the voltage values transported as generally used. n.b. A … Continue reading Analog Audio Cables – VII

RCA and MiniJack Cables and RCA connectors or PIN and MiniJack are mostly used for the transport of analog audio signal consumer (- 10 dBV or 0.3 V) generally to send and receive signals from CD players, radio tuners, plates for vinyl LP. Once in some cases it was also possible to find them as … Continue reading Analog Audio Cables – VI

Objective differences between XLR and Jack In terms of sound quality as seen in previous articles, the unbalanced system is better than his successor balanced be it passive or active as it does not have the center-tapped transformer or electronic balancing circuitry means. The Jack is much more used of XLR to carry voltages in … Continue reading Analog Audio Cables – V

Active mode In the passive balance transformer has the task of balancing and unbalancing the signal to then be amplified if necessary by an amplifier device, the active audio balance instead exploits the use of electronic components such as amplifiers to balance-unbalance and very often also amplify the signal itself. In terms of listening, the … Continue reading Analog Audio Cables – IV
