- Sound pressure level SPL
Sound levels alignment of individual speakers and setup of LFE channel about 10dBSPL higher than the surround level.
- Real time analyzer RTA
Fine tuning the system performance with pink noise at each seating position. The reference spectra of speakers may be captured for comparative measurements, thus achieving the same sound performance of all speakers.
- 1/12 octave analysis
Loading standardized X-Curve tolerance bands according ISO 2969 or SMPTE 202M for reference measurements with selectable 1/1, 1/3, 1/6 or 1/12 octave band resolution.
- FFT analysis
Analysis of reflections and cancellations (comb filter effects) for improving the room architecture and speech intelligibility.
- RT60 reverberation time
Verifies the room acoustics for optimized system performance and speech intelligibility.
- Polarity
All speakers shall be verified for the same polarity, thus achieving a broad stereo or surround sound image.
- Delay
Setup of acoustical delays for optimized surround sound performance.
