Loudspeaker

A transducer that converts the electronic audio signal back into a sound wave. Due to physical constraints, it is difficult for one loudspeaker to convert accurately the entire audio spectrum, so manufacturers use a number of drivers in a single cabinet to properly reproduce the full frequency range. Each frequency-range speaker is given its own name. High-frequency units are called tweeters, midfrequency units squawkers and low-frequency units woofers. It is not uncommon to also get very low-frequency units called sub-woofers. It has become a common practice for manufacturers to incorporate amplifiers within the sp

Microphone

A transducer designed to convert a sound wave into an electrical current. Microphones are one of the most important elements of any signal path as they are the initial conversion point for any signal to be recorded. It is therefore important that highquality microphones are used in recording studio situations. All microphones have their own ‘sound’ due to tiny fluctuations in their frequency response, and many microphones are manufactured for a particular purpose or even instrument.
