6. SPECIFICATIONS
6.1 dV-DOSC SPECIFICATIONS
L-ACOUSTICS specifications are based on measurement procedures which produce unbiased results
and allow for realistic performance prediction and simulation. Some of these specifications will appear
conservative when compared with other manufacturer's specifications. Measurements are conducted
under free field conditions and scaled to a 1 m reference distance unless otherwise specified.
Frequency response (+/-3 dB) 160 Hz - 18 kHz (single unit)
100 Hz - 18 kHz (coupled array)
Full system bandwidth with SB218 25 Hz - 18 kHz
Sensitivity
(average SPL over component's rated bandwidth, equivalent to 2.83 Vrms at 1 metre)
MF 99 dB SPL (100 - 800 Hz)
HF 109 dB SPL (800 - 18k Hz)
Long Term Power Rating (100 Hz HPF for low section, pink noise with 6 dB crest factor)
