The abbreviation of the frequency operator, commonly known as the "amplifier", is the most fundamental device in the audio system. Its mission is to expand the weak small electrical signal from the signal source (in the professional audio system) A sound. The effect of the amplifier is to expand the weak signal from the sound source or the front -level extensor to promote the sound of the speaker. The effectiveness of a set of amplifier amplifiers in the audio system is indispensable.

   The amplifier is the largest clan in various audio devices. The effect is mainly to expand the weaker small signals of the audio source device input, and a sufficient current occurs to promote the loud release of the speaker. Because of considering power, impedance, distortion, dynamics, different use scope and control and conditioning function, different amplifiers are different in the internal signal processing, line planning and production process.

    In addition to the function of the general amplifier's enlarged signal driving speakers, the frequency transfers can also use the screaming of the scene to ensure the quality of the voice transmission. Maintaining audio equipment will not burn out due to howling.

    The frequency power amplifier is widely used in high -level multimedia classrooms, training rooms, small conference rooms or other simple sound expansion occasions. The microphone can directly connect to the frequency transposition amplifier. Entry sound expansion.
