What is Jack Plug and Lead cable?
Jack plug is the most basic form of connector found on instruments such as Guitars, keyboards etc. The jack plug connector normally carries a mono signal, but there are also a jack plugs with ‘TRS’ (like the headphones) setting that carry a stereo signal. Lead cables are the wires that join the two connectors. Lead cables can be balanced (microphone lead) or unbalanced. (guitars/ keyboard).
What do you mean by ‘level’ in Sound Engineering?
Level refers to the intensity of the audio signal.
What do we mean by ‘loudspeakers’?
We all know loud speakers very well, but technically speaking they are ‘transducers’ that converts the electronic audio signal back into a sound wave. For accurate conversion of the audio signal to sound and to capture the complete frequency range, these loudspeakers have inbuilt small circuits which are named depending on the frequencies it will be handling, for example ‘tweeters’ handle high frequency signal, mid frequency is handled by ‘squawkers’ and low frequency is handled by ‘woofers’. Loudspeaker companies also sell these frequency handling units separately.
What is a Microphone?
This is a very large topic to discuss. We will explain it in brief here, but make sure to check our website for videos on Microphones for better understanding. Just like a loudspeaker, microphone is also a transducer but designed to convert a sound wave into an audio signal or a electrical current. Microphones are largely classified based on its pick up pattern and its frequency response. Therefore many Microphones are manufactured for specific application. Mainly Microphones are divided into two types Dynamic microphones and Condenser microphones. There are also Ribbon microphones which are a part of the dynamic mics but are rarely used these days.
What do you mean by a Cardiod Microphone?
The word “Cardiod” basically tells a lot about the sound pickup pattern of the microphone. Cardioid or uni-directional microphones typically have a heart-shaped pick-up pattern and are sensitive in only one direction. This means they have less sensitivity to instruments to the side or behind them. In studios this means that they pick up best the instrument they are pointing directly at and are less sensitive to other instruments in the room.
