D.I. Box – II

Remember that each example made and advice given is referred to D.I. Box having the same quality, while as we know in a real context there are Passive D.I. Box better than Active ones and vice versa independently of the use made of it. Passive D.I. Box The D.I. Box Passive can be as simple … Continue reading D.I. Box – II


D.I.Box – I

The D.I. Box (direct injection box) (fig. 1) is a component which serves to adapt the level of voltage and impedance of an outputting signal from an audio device (generally musical instrument, unbalanced signal) and entering into another having characteristics of different circuit, such as to optimize the correct load transfer without sending distortion in … Continue reading D.I.Box – I

Decibel and Meters – VI

Loudness Manager or Loudness Engineer In summary, controlling the loudness of a music program is fundamental not only to fit reenter in the normative terms of law (see broadcast and limits un live) but also to follow recommendations by performed studies and experiments guarantee at the time the best possible solution to get quality sound … Continue reading Decibel and Meters – VI

Decibel and Meters – V

Where do we find the meter in the most commonly used audio equipment? Following the path that generally goes through the audio signal we see what common equipment (modern) use the scales in decibels and how. Premise There is no defined meter number, the number of meters depends on how many channels / signals we … Continue reading Decibel and Meters – V

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

Decibel and Meter – III

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

Decibel and Meter – II

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

Analog Audio Cables – VII

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

Analog Audio Cables – VI

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
