Measured at distances of 4m and 8m, in free field and on ground plane. Sensitivity is calculated based on measured
SPL response averaged in 200Hz-3kHz range and scaled back to 1m.
2 AES refers to AES2-2012 standard. IEC refers to IEC 60268-5 standard. Max continuous SPL calculated based on sensitivity
and AES power handling. IEC short-term power tested using IEC pink noise with 9dB crest factor. The crest factor was specifically
increased to reflect real-life parameters of digital cinema sound tracks. Maximum peak SPL calculated using peak voltage during
IEC short-term power test.
3 Averaged in 500Hz-16kHz range, at -6dB.
4 4 cables required when flown. See User Manual for details.
