2 Continuous Pink Noise Rating is IEC-shaped pink noise with a 6 dB crest factor for 100 hours continuously. Continuous Program Power is a conservative expression of the system’s ability to handle normal speech and music program material, and is defined as 3 dB above the Continuous Pink Noise Rating.
3 Half-space (in ceiling) average 1 kHz to 16 kHz.
4 For protection against driving below resonant frequency and to keep transformer out of saturation.
JBL continually engages in research related to product improvement. Changes introduced into existing products without notice are an expression of that philosophy.
