Resumen del manual
See AES Recommended Practice section. Power Frequency Response: 500-20,000 Hz (essentially flat 500-3,000 Hz with 6-dB-per-octave roll-off to 20,000 Hz, rapid roll-off beyond) Nominal Impedance, on HP Series Horns above 500 Hz, DH2A: 8 ohms DH2A-16: 16 ohms Minimum Impedance at 7,000 Hz, DH2A: 6 ohms DH2A-16: 12 ohms dc Resistance, DH2A: 4.5 ohms DH2A-16: 11.0 ohms Long-Term Average Power Capacity on HP Horns, Indicated Bands of Pink Noise, 8-Ohm Impedance Assumed, 24 Hours, 10-dB Crest Factor: 30 watts (800-20,000 Hz) 2 Hours, 6-dB Crest Factor: 40 watts (800-8,000 Hz); 60 watts (1,500-15,000 Hz) Nominal Efficiency, 800-3,000-Hz Pink Noise, 8-Ohm Impedance Assumed: 25% Maximum Long-Term Acoustic Power Output (24 hours): 7.5 watts Recommended Minimum Crossover Frequency: 800 Hz Sound Pressure Level at 1 Meter, 1 Watt Input Averaged from 500 Hz to 5,000 Hz, HP4020 horn:1 115dB HP6040 horn: 113dB HP9040 horn: 111 dB HP64, HP94: 111 dB HP420 horn: 114dB HP640 horn: 112dB HP940 horn: 110 dB HP1240 horn: 108 dB Throat Diameter: 4.92 cm (1.94 in.) Voice Coil Diameter: 5.08 cm (2.00 in.) Voice-Coil Construction: Pure aluminum wire wound on high-temperature polyimide coil form Diaphragm Construction: Integral all-titanium construction consisting of spherical diaphragm dome and geometrically optimized suspension; high-temperature, long-duration-cure adhesive bonds the coil form to the diaphragm. Electrical Connection: Screw terminals, each of which will accept a pair of 12-gauge wires and any smaller size. 1. Measured on axis in the far field with 1 watt input of band-limited pink noise from 500-5,000 Hz and calculated to 1 meter equivalent by inverse square law. Polarity: A positive voltage applied to the positive (red) terminal produces a positive acoustic pressure in the throat Mechanical Connection: Bolt on, four equally spaced holes on a 10.2-cm (4.00-in.) diameter circle, Otros modelos de este manual:
