What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

PSB Avante loudspeakers


The most popular model in the PSB line, the Avante is recommended for use in conjuction with home stereo systems. It is ideal for both recerational and professional listening where reliability, accuracy and compactness are required. Professional users include the CBC (cost to cost), the national ARTS Centre, The National Research Council, Tv and radio stations, recording studios.
" Transient response is excellent, with good attack and well damped suspension of ringing. A very realistic sttereo image is created, both in spread and depth, as a result of the good dispersion pattern and phase coherence of the Avanté"
