Align and verify cinema sound systems to meet target performance.

Public Cinema sound has to be so much better than the incredible sound experiences of Home Cinemas in order to encourage audiences to come to the movies. The NTi Audio Cinema Meter is the tool you need to achieve this.

Modern soundtracks can create a totally engaging experience that immerses and thrills the audience, but only if the speaker system is setup correctly. NTi Audio provides a handheld solution for complete calibration and verification of cinema sound systems.

Cinema Meter XL2

An XL2 Analyzer, with the Cinema Meter Option installed, forms the dedicated solution for efficient calibration and repetitive verification of cinema loudspeaker systems in accordance with SMPTE ST 202:2010 and SMPTE RP 200:2012. An interactive assistant guides the user through the calibration and verification process. The M2211 Measurement Microphone with class 1 frequency response is recommended for accurate measurements in cinemas, as the specified tolerance bands are very tight.
