Detailed Product Description: | Henan line array speaker system sound How to improve the reliability of daily life, even if the loss is Yang Shun unit change in the event of power loss matching amplifier and speaker system will happen fairly, the impedance of the speaker unit speaker unit G impedance including inductance, capacitance and resistance, inductance and capacitance varies with frequency, although a nominal impedance of the speaker system has changed so much, it will affect the stability of the entire sound system, JBL latest DCD double impedance differential drive design circle becomes [pure resistance] resistance, not affected by changes in the frequency, so that the entire sound system stability. Three reasons: improper operation, the amplifier output power is too great when the show reached its climax, inside a warm atmosphere, the need Henan line array audio program Jiaming Yang Cheng 1393 + 90 664 + 17 * City technology market in Milan sun, Building 5, Unit 2, 208 to be enhance the sound pressure at the time to increase the signal, the microphone input signal is too large lead amplifier overload clipping, produce a large number of harmonic waveform distortion, damage tweeters produce strong acoustic feedback howling microphone, amplifier strong overload, damage to the speaker system to this end, modern The new speaker system to take a variety of protective measures, which can be divided into two categories: improving the cooling power of the speaker unit so that it does not occur when thermal overload protection device limiting damage to the installation in the speaker box, when the driving power and peak power When the level exceeds the rating of the speaker, the limiter exceeds the power level using nonlinear resistor (lamp) of the voice coil to prevent these measures to improve the ability of the speaker against over load, but can also affect the dynamic range of the sound, so that broad enough range, timbre and dim fuzzy feeling. Therefore, the best way is to take measures on the amplifier, so that it does not produce an output clipping and power overload problem linear type of sound and performance indicators, also known as line array speaker sound system, sound system, it is extremely important a link. Because the audio playback quality linear impact on the entire sound system is great. 1393 + 90 664 + 17 Jiaming Yang Zheng * City technology market in Milan sun, Building 5, Unit 2, 208 Henan line array audio program |
