Sofa butler technology AV amplifier and HIFI amplifier is the most common two kinds of equipment in the speaker equipment market. For many small white users, he may not know "What AV amplifier, what is HIFI amplifier", how to buy Need a power amplifier? Do not worry, today, the author and I said to you: The difference between AV amplifier and HIFI amplifier, and what kind of power amplifier is good.
What is an AV amplifier
The AV amplifier's A (audio) indicates audio and audio, and the V (video) indicates audio and video. Therefore, the AV power amplifier is a combination of audio and video signal processing audio and video amplifiers, emphasizing the sound field atmosphere, dedicated to home theater. .
AV power amplifier
What is a HIFI amplifier
HIFI amplifier Hi-Fi is the abbreviation of English Hight-Fidelity, literal translation as a high fidelity, it requires the audio equipment in the playback process, the sound signal indicators are amplified, processing, in order to restore the original appearance of the sound source Emphasis is on authenticity and is dedicated to music, such as classical music.
The difference between AV amplifier and HIFI amplifier
In the above section, we briefly learned about “What is an AV amplifier and what is a HIFI amplifier?†and realized the difference between the AV amplifier and HIFI amplifier. The former is mainly used in the field of home theater and requires audio and video equipment. While the latter only needs to provide audio equipment, focusing on listening to music, then what is the difference between AV amplifier and HIFI amplifier? Let's continue reading.
1, the number of channels is different
AV amplifiers have 4-9 channels to drive multiple speakers to create a surround sound field. For example, the Dolby AC-3 requires 5.1 channels. The Hi-Fi amplifier is generally two-channel when playing, ie, the signals of the left and right two channels are amplified, and the left and right two groups of speakers are pushed, thereby forming a stereo sound field.
2, different parameters
The parameters of AV power amplifiers mainly include output power, harmonic distortion, signal-to-noise ratio, frequency range, rated impedance, and damping coefficient. In particular, the parameters such as channel isolation, delay time range, and various sound field modes are emphasized. More indicators for the video section. Although Hi-Fi amplifiers also have these parameters, they emphasize harmonic distortion and signal-to-noise ratio.
HIFI amplifier
3, different sound atmosphere
The AV amplifier is mainly designed to create a sound field, emphasizing the sense of orientation of the sound, and simulating the atmosphere of the listening environment. Hi-Fi amplifiers are often designed with high fidelity as their design purpose, paying attention to authenticity. Amplify the signal sent by the signal source, mainly for the appreciation of music, vocals, etc., in pursuit of the true effect of the sound.
Can AV amplifiers be used as HIFI amplifiers?
AV power amplifier put together two audio and video signal processing amplifiers, while HIFI power amplifiers only have audio amplifiers. Can we use AV power amplifiers instead of HIFI power amplifiers? The answer is no. There are three reasons for this.
1, AV power amplifier when playing a large dynamic range of music
The output power of the AV amplifier in the two-channel state is greater than the output power in the four-channel state. At this time, using a large dynamic range of music for auditioning, obviously feel powerless. The Hi-Fi amplifier seems to be calm.
2, AV power amplifier line affects sound quality
AV amplifier sets a variety of video, audio ports, access to multiple audio and video signal sources, resulting in multiple signal lines and miscellaneous, easily lead to mutual interference of the signal. The original rich high-frequency components of a good signal source are attenuated or interfered, so that the listener does not enjoy the high-fidelity effect.
3, AV power amplifier screen will interfere with sound quality
The AV power amplifier panel has a large-scale fluorescent display. Character display is driven by the pulse signal, which will radiate many electromagnetic interferences to the surroundings, which will obviously affect the sound quality.
It is said that the AV amplifier cannot replace the HIFI amplifier, but it does not have to be so true. If you do not require too much sound quality, the AV amplifier can also be used as a HIFI amplifier. For example, Onkyo's AV amplifier is recognized by the industry as both Can be used in home theater, but also can be used in music appreciation amplifier equipment. Of course, the final effect is not as good as a professional HIFI amplifier.
