Conference speakers Microphone common current configuration in three ways: 1. Conference Microphone + mixer; 2. Conference Microphone + smart mixer or conference microphone + digital media matrix; 3. Hand in Hand digital conference microphone. Their impact on the climate has a strong anti-jamming performance microphone, ideal for a number of new areas, such as the use of Kara OK expedition conference microphone, day and night operation in outdoor dual-channel microphone Technica microphone, face extreme temperatures, outdoor weather conditions super-cardioid condenser microphone microphone, the microphone is still outstanding performance. In 1961, the industrial fair in Hanover, Germany, Sennheiser introduced the MK102 and MK103 microphone type. Both microphones interpretation of a new manufacturing concepts --RF microphone RF capacitance, which uses small, thin diaphragm, with small size, light weight, while ensuring excellent sound quality; In addition, this microphone on very sensitive to electromagnetic interference. To release the microphone and microphone amplifier clinic in the studio recording the impact on sound quality, you must first understand the evaluation method of the specific object sound quality, sound quality and sound. Therefore, this paper introduces the sound, the sound quality, the factors affecting the sound quality, and the subjective evaluation and objective evaluation method analysis platform sound quality will be described. Then with a microphone and microphone amplifier for the point, by contrast, induction of different microphones at the same recording microphone amplifier recordings, as well as different microphone amplifier with a microphone in recording recordings analyzed herein set Topics were solving.
