Splitters and Summings – I

Audio Splitter The Audio Splitter (fig. 1 and 2) is a useful tool when you need to divide an audio signal into multiple parts and also seen as a D.I. Box can be in some cases a Splitter. For example, in a live situation where you have the F.O.H (front of house mixer). (for mixing … Continue reading Splitters and Summings – I

Stage Box – III

Digital Interfaces As defined, Digital Audio Mixers and Digital Stage Boxes, but also as we will see any audio device that allows to accept and transmit to this type of protocols (such as power amplifiers, radio microphones and signal processors) to dialogue each other they need Interfaces that work in the same protocol, some already … Continue reading Stage Box – III

Stage Box – II

Digital Stage Box or I/O Interface For the management and transfer of audio signals from and toward the Stage Box, in digital domain it does not have input and output connections but bidirectional connections are used (generally on conductors Cat 5 - 6 - 7, BNC, Fiber Optics) (for Standard such as MADI, DANTE, AES50, … Continue reading Stage Box – II

Stage Box – I

STAGE BOX A Stage Box as the word itself tells is a module that is generally found on the stage (live concert) or in the recording room (recording studio context) or however in proximity of microphones and signal lines whose task is to collect all these lines and transfer them over long distances, example from … Continue reading Stage Box – I

D.I. Box – III

Objective differences between Passive D.I. Box and Active D.I. Box (from Radial Engineering Ltd.) The representations that follow are references of 2 D.I. Box of the highest quality. Passive D.I. Box (Radial JDI) Activate D.I. Box (Radial J48) Dynamic and Frequency response: The Passive D.I. Boxes dominate the aspect of Dynamics, but only in the … Continue reading D.I. Box – III

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
