This article mainly introduces the meaning of phono interface, which is very detailed and has certain reference value. Friends who are interested must finish reading it.

The phono interface is an analog audio input interface, which is specially used to access the analog jukebox and belongs to a high impedance interface; generally, after the audio source is amplified by the front stage of the PHONO interface, the amplitude of the signal is too large, which exceeds the input range of the front stage of the power amplifier, resulting in distortion.

After the power amplifier, CD means CD, VCD/DVD (CD), TUNER is connected to the AM/FM receiver head, AUX is connected to the backup auxiliary interface, and PHONO means analog audio input interface, which is specially used to access the analog disc player, high impedance interface, and TAPE access tape booth.

The main contents are as follows: 1. The signal source is different: when using the plug-in connector, the signal source will be processed accordingly, so the signal strength of these kinds of sockets is also different after accessing the signal source.

2. Different locations: these access sockets are different in the location of the device, and the most commonly used ones are placed on the far left, but they are also different according to the location of the equipment.

3. The access is different: because the access type of each socket is different, the access of the socket behind each power amplifier is different.

CD:CD 、 VCD/DVD

TUNER:AM/FM radio head

AUX: backup secondary interface

PHONO: turntable record player

TAPE: tape booth

Extended data:

It is important to know that the channel of the AV amplifier is backward compatible. The amplifier has 32 channels and can also be connected to the 5.1channel speaker. The number of speakers is generally affected by the room environment and shape, sofa against the wall, or the room is flat, width direction projection, the rear surround speakers can not be installed, but does not affect the purchase of other speakers.

It is important to know that the decoding technology and amplification capability of the combined home theater power amplifier are the two cores. The reason why the Japanese AV power amplifier monopolizes the market is that the decoding technology is leading, the product update iteration is rapid, and the high and low grades are distinct. The more high-end it is, the stronger the decoding ability is, and the greater the amplification power is.
