Detailed Product Description: | Henan line array loudspeakers offer sound power handling capability is the case with pink noise signal and press (AES2-11984) treatment plus two hours of continuous work after their permanent change electrical and mechanical properties of not more than 10% of the measured technical parameters. Load (heat) after SPL drop (also known as power compression) on all product specifications are nominal power of the manufacturers custom sound signal is not a sine wave signal, but a random, these random signals are available can be expressed as the number three, RMS (RMS), also known as the root mean square value, based on a measurement signal peak amplitude of the sinusoidal signal, close to the mean, basically represents the heat energy of the signal line array sound Henan offer. Peak (Peak) is the signal reaches the maximum level of Jiaming Yang Cheng 1393 + 90 664 + 17 * City technology market in Milan sun, Building 5, Unit 2, 208 in a sine wave, the peak level is greater than the rms level 3dB, for music signal, the peak level exceeds the rms displacement of up to 10-15dB in assessing the ability of a speaker, the peak is important, the peak factor for explaining the peak level and RMS level ratio for press AES2-1984 of pink noise source, the peak factor of 6dB, that is four times the peak voltage rms voltage. , Is a linear array of acoustic optimum value at the factory and selected test signal conditions, when the rear (after such full power is equal to or greater than 20 seconds) into the working state linear audio, the voice coil and the magnet heating temperature, due to They changed the original characteristics of performance degradation before heating unit, then the actual sound pressure output will be reduced, the conventional line array sound, such as a voice coil temperature of 60 degrees -80 degrees, common nominal decline 3dB SPL for tolerance limit, such as excellent voice coil cooling, the temperature reached 100 degrees, the actual Jiaming Yang Cheng 1393 + 90 664 + 17 * City technology market in Milan sun, Building 5, Unit 2, 208 sound pressure drop up to 6 to 8dB, which is pretty amazing decline, as previously title and doubling the line array sound pressure level 3dB if only to enhance the linear sound pressure level by up to 6dB, to make up such a large SPL drop a line array sound must be increased from the original only four, very sorry, no audio industry SPL nominal decline this must be good to improve the thermal design of the speaker unit. |
