Gain anti-howling processor\"\"<\/span><\/h2>\n
\r\nThe gain anti-howling processor series products are a new generation of equipment designed by our company for conferences and teaching. The line adopts dual anti-howling technologies of five-band parametric equalization and digital frequency shifting, which effectively increases the pickup distance of the microphone and increases the microphone gain to 5-14dB, making speaking easy and natural. Due to its anti-howling effect, it more effectively protects your power amplifiers, speakers and other valuable equipment, and is the protector of sound reinforcement equipment. The user-friendly design makes your operation simpler. There is no need to debug before the meeting. You can enter the meeting immediately after turning on the power. The workmanship is exquisite and the products are rigorous and reliable. The sound quality is clear and the fidelity is high, ensuring the quality of voice transmission. Choose with ease. The volume can be adjusted independently, giving you easy debugging options. Feature 1: Built-in ALC function, amplified signal distortion is small. Increase design freedom with gain adjustment capabilities. With the ALC function, it is easy to control the input of excessively large signals, and the amplified signal has little distortion. In addition, the limiting level (limiting level when the input signal is exceeded) and microphone gain can be freely adjusted, and can be set arbitrarily according to the equipment equipped.\r\n<\/span><\/pre>\n
Feature 2: Contributes to improving sound quality through low input noise voltage and high gain setting. \r\nMicrophone amplifiers receive tiny sound signals and amplify them. An amplified signal with a high S\/N ratio is required. NJM2783 can achieve low output noise voltage and high gain, which can reach more than 100db. Therefore, the sound quality of the device can be greatly improved. \r\nFeature 3: Wide power supply voltage (2.7~13V), applicable to various fields. \r\n\r\n(2) Technical parameters:\r\n\u25cfPower supply mode: AC220V-230V, 50\/60Hz\r\n\u25cfMicrophone and line input frequency shift effect switch selection\r\n\u25cfConference system local speakers realize independent effect connection port (EFX)\r\n\u25cfFrequency shift amount: 5 Hz\u00b11 Hz\r\n\u25cfSound transmission gain improvement 5-14 dB\r\n\u25cfLine input impedance \u22655K\u03a9\r\n\u25cfLine output impedance\u2264600\u03a9\r\n\u25cfFrequency response: non-shifted state 20 Hz-20K Hz\r\n            Frequency shift state 150 Hz-15K Hz\r\n\u25cfWorking power supply voltage 2.7\uff5e13V\r\n\u25cfMono microphone amplifier\r\n\u25cfEquipped with Auto Level Control (ALC) function\r\n\u25cfGain can be adjusted with external components (+20\uff5e63dB)\r\n\u25cfUse external components to adjust the limiting level (200mVrms\uff5e2Vrms)\r\n\u25cfGain switching possible: 0dB\/20dB]\r\n\u25cfBuilt-in buffer amplifier\r\n\u25cfLow input noise voltage 1\u03bcVrms\r\n\u25cfBuilt-in high-frequency noise countermeasure circuit<\/span><\/pre>\n
