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.

UREI 813


Time Aligned™ Studio Monitor System
Features:
First Time Aligned™ monitor system designed for the professional studio
Features UREI 800 series TA™ network (patentpending)
6048G duplex with UREI custom H.F. horn for extended and more uniform H.F. response
Second L.F. 15" direct radiating driver fed from 3-way TA network for extended L.F. response and higher power handling capability at low frequencies
Graeter than 11,5 cu ft. Enclosure with pressure cotrol aperture for excellent L.F. damping, good efficiency and low distortion.
Unique enclosure damping method provides high efficiency conversion of low frequency aound pressure to adiabatic enrgy.

The 813 Studio Monitor System is the first generation product of a joint R & D effort of UREI and E. M. Long Associates. The Time Align™ Technique is a realtime design method, utilizing proprietary instrumentation developed by Long which allows the driver placements and network parameters to be adjusted simultaneously, achieving near perfect alignment of the frequency components of a complex transient waveform as heard by a listener.

The importance of time (phase) parameters of loudspeaker systems, in addition to smooth frequency response, has been postulated for many years. These group time delay anomalies may be severe in some multi transducer systems, although they may exhibit satisfactory or even excellent frequency response.
For stereo applications the model 813 Studio Monitor System is built in "mirror-image" (813 L, 813 R) to produce identical dispersion towards the listening position between two systems. The series 800 TA networks with the 800H custom H.F. horn, are also available separately in two way and three way configuration for both the 6048G and the 604E.
