The main role of the microphone preamplifier is to raise microphone level signals to line level, although some units may offer extra features such as equalisation and compression. Microphone preamps differ in sound and while some devices may be broadly described as ‘transparent,’ others alter the nature of audio material noticeably. In addition to that, equipment deemed as ‘transparent’ will …
The most important areas to treat are the so-called mirror points – those areas of reflective surface that bounce the sound from the monitors directly back to your listening position. You can find these by getting someone to hold a real mirror flat against the wall when you are seated in your usual monitoring position. At any point where you …
So far we have not considered what was happening in the field of synthesizer design in Japan, where one of the biggest players was a company that predated all the American and British synth designers by more than half a century. Yamaha was founded in 1887, and built up a strong tradition of building pianos and reed organs, as well …
In order to determine the electrical input level to a sound system we need to measure the electrical output generated by the system microphone when it is subjected to a known sound pressure (SP). In making such measurements an LP of 94 dB (1 Pa) is recommended as this value is well above the normally encountered ambient noise levels.

It was performed with audience at the Cathedral of Saint John the Divine in New York in 1996 during a convention of the American Guild of Organists, Dennis Keene, conductor. The Cathedral is the largest gothic structure in …
Depending on the program material and desires of the producer, an alternate to either a pair of discrete direct radiators, or to surround arrays, is to use special radiation pattern surround loudspeakers. A pair of dipole loudspeakers arranged in the AES/ITU configuration, but with the null of the radiation pattern pointed at the listening area, may prove useful. The idea …
