CHAPTER 1: INTRODUCTION

8

Integration of the X-800C within Meyer Sound EXP cinema
installations is easily achieved with MAPP Online Cinema, a
powerful, cross-platform, Java-based application for accu-
rately predicting the coverage pattern, frequency response,
impulse response, and maximum SPL output of Meyer
Sound cinema loudspeakers.

Meyer Sound’s optional RMS™ remote monitoring system
provides comprehensive monitoring of system parameters
on a Windows

®

-based computer.

The X-800C cabinet is constructed of premium birch ply-
wood and coated with a durable, low-gloss, black textured
finish.
