Document Summary

Chapter 2 the anatomy of high-fidelity systems: Riaa equalization amplifier: a collection of electronic circuits which boosts and equalizes the signal coming from the magnetic phono cartridges. (recording industry association of america) is found in the preamp/control centre. Condensations: regions along a sound wave where the pressure is largest. Rarefactions: regions along a sound wave where the pressure is the smallest. Law of refraction: when sound travels from a low-velocity medium into a higher velocity medium the refracted sound will bend away from the normal. If the sound travels from a higher- velocity medium into a lower-velocity medium, the refracted sound will bend toward the normal. Reverberation: numerous reflections of sound which arrive close together and cannot be perceived as individual echoes. Reverberation time: the time required for the reverberated sound to decay to one-millionth of its original level after the speakers have been turned off. Typical reverberation times are between 0. 5 and 2. 2 seconds.
