1、JBL Professional Series RadioFans.CN 收音机爱 好者资料库 1 This catalog contains JBLs current Professional Series loudspeaker systems, components and elec tronics. They reflect the very latest developments in acoustic and electronic engineering, and will provide the performance, durability and versatility re

2、quired of profes sional installations. Transducer capacities are described in terms of continuous program power, which is twice continuous sine wave power (RMS). Expressed another way, continuous program power is 3 dB greater than continuous sine wave power and is a conservative expression of the tr

3、ansducers ability to handle normal speech and music program material. Horn and lens distribution patterns indicate the inclusive angle through which output is no more than 6 dB below on-axis response at the selected frequencies. Elec tronic equipment is also conserva tively rated: amplifier outputs

4、are given in Watts RMS at specified impedance with distortion at or below the rated maximum, and distortion figures are referred to full rated output levels. All quoted operational characteristics are based on actual production units not laboratory prototypes. Professional Products Warranty Every JB
