1、JBL . Professional Series RadioFans.CN 收音机爱 好者资料库 JBL Professional Series This catalog contains JBLs current Professional Series loudspeaker sys tems, components and electronics. They reflect the very latest develop ments in acoustic and electronic engineering, and will provide the per formance, dur

2、ability and versatility required of professional installations. Transducer capacities are described in terms of continuous program power, which is twice con tinuous sine wave power (RMS). Expressed another way, continuous program power is 3 dB greater than continuous sine wave power and is a conserv

3、ative expression of the transducers 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 se lected frequencies. Electronic equip ment is also conservatively

4、 rated: amplifier outputs are given in watts continuous sine wave at specified impedance with distortion at or below the rated maximum, and dis tortion figures are referred to full rated output levels. All quoted operational characteristics are based on actual production units, not laboratory protot

5、ypes. Unless otherwise noted, all active electronic products are designed for operation on 120/240V AC, 50/60 Hz.
