What does phono interface mean?

The phono interface is an analog audio input interface. It is specially used to connect to analog turntables. It is a high-impedance interface. Generally, after the sound source is amplified by the preamp of the PHONO interface, the amplitude of the signal is too large and exceeds the preamplifier of the power amplifier. input range, distortion will occur.

What does phono interface mean?

The CD behind the amplifier means CD, VCD/DVD (compact disc), TUNER is connected to the AM/FM radio head, AUX is connected to the spare auxiliary interface, and PHONO means the analog audio input interface, dedicated For connecting to analog turntables, high-impedance interface, TAPE is connected to the tape deck.

1. Different signal sources: When using the plug-in connector, the signal source will be processed accordingly. Therefore, the strength of the signal after the signal source is connected to these types of sockets is also different.

2. Different positions: The positions of these access sockets on the device are different. The most commonly used ones are placed on the far left, but the positions are also different depending on the device.

3. Different access: Because the specified access type of each socket is different, the socket access behind each power amplifier is different.

CD: CD, VCD/DVD

TUNER: AM/FM radio head

AUX: Alternate auxiliary interface

PHONO: Turntable record player

TAPE: Tape deck

Extended information:

You must know that the audio channels of AV amplifiers are backward compatible , the amplifier has 32 channels and can also be connected to 5.1 channel speakers. The number of speakers is generally affected by the environment and shape of the room. If the sofa is against the wall, or the room is flat and projected in the width direction, the rear surround speakers cannot be installed, but it does not affect the purchase of other speakers.

You must know that decoding technology and amplification capabilities of combined power amplifiers in home theaters are the two cores. The reason why Japanese AV power amplifiers monopolize the market is that they have leading decoding technology, rapid product updates and iterations, and distinct middle, high and low grades. The higher the high-end, the more decoding The stronger the ability, the greater the amplification power.
