Notes:
1- Calculated maximum peak SPL at 1 meter distance, half-space, speaker operating at rated RMS power with 6 dB crest factor pink noise
input, 35- 100 Hertz.
2- Measured maximum RMS SPL referenced to 1 meter distance, loudspeaker operating at rated RMS power with 6 dB crest factor pink
noise input, 35- 100 Hertz. Measurement taken at 2 meters, half-space, after 15 minutes of full power operation.
3- Maximum continuous SPL at 1 meter in dBA. The dBA scale is typically used to identify sound sources which have the potential to cause
permanent hearing loss.
4- Maximum input power tested in accordance with AES and/or IEC recommendations, 35- 100 Hertz band limiting, 6 dB signal crest factor.
5- QSC DSP configurations available at http://www.qscaudio.com. Parameters for alternative processing hardware available upon request.
