Movie Theater Installation
A properly designed and calibrated sound system makes all the difference in the enjoyment of a film or movie presentation. Unlike many other audio application scenarios, movie theaters are designed to exhibit good acoustic properties. Most sound system calibrations center around creating a broad, flat, high-fidelity audio response throughout the seating area.

A multiple-channel theater surround sound system is shown in (Figure 7.5), and a connection diagram is shown in (Figure 7.6). The PSR1212 can customize the response of each loudspeaker through the use of parametric equalizers, filters, and compressors designed to compensate for speaker and room characteristics and deficiencies. A complete description of these adjustable parameters (and how to configure them) is found in the PSR1212 Installation and Operation Manual.

A CD player and tape deck can be connected to play background music between movies—over both the theater and lobby speaker systems, and a microphone can be used to facilitate the occasional announcement.
