Coaxial audio cable and lotus audio cable are two common audio cables, both of which can be used to connect different devices in the audio system, such as computers, decoders, power amplifiers, etc., but there are also some differences and characteristics. Although the appearance of the plug looks the same, there are still some differences between the coaxial audio cable and the Lotus audio cable.
Coaxial audio cable
Coaxial audio cable is a technology that uses coaxial cables to transmit digital audio signals. It is a high-fidelity and high-definition audio transmission method that can transmit LPCM streams and surround sound compressed audio signals such as Dolby Digital and DTS. The connectors of coaxial audio cables are divided into two types: RCA (commonly known as lotus connector) and BNC. Among them, the RCA connector is more common. It looks like a round metal plug with a raised needle in the middle and a circle of elastic around it. sheet metal.
The advantages of coaxial audio cables are：
01.The electro-optic and photo-electric conversion processes are reduced, resulting in higher fidelity.
02.The time base error of digital coaxial transmission is very small, so this transmission method has a better performance on sound quality.
03.It can transmit multi-channel surround sound signals, which improves the sense of stereoscopic and immersion.
The disadvantages of coaxial audio cables are：
01.The loss of long-distance transmission is large, so high-quality cables and connectors are required.
02.It needs to be used with devices that support digital audio input and output, not for devices with only analog audio interfaces.
03.It may be affected by external electromagnetic interference or ground loop interference, which will affect the signal quality.
Coaxial audio cables are suitable for scenes that require high-fidelity, high-definition, and multi-channel surround sound, such as movie theaters, digital music, and webcasting.
Lotus audio cable
Lotus audio cable is a technology that uses RCA terminals to transmit analog audio signals. It is a simple, intuitive, low-cost, and highly compatible audio connection method that can transmit stereo or mono signals. Lotus audio cables are divided into left and right channels. Generally, the right channel is marked in red, and the left channel is marked in white or black. The appearance of the Lotus audio cable is similar to the RCA connector of the coaxial audio cable, but the internal structure is different.
The advantages of the Lotus audio cable are:
01.What is transmitted is an analog audio signal, which does not need to be decoded, and can be directly connected to the post-stage amplification process.
02.It is the most common and basic audio connection method at present, and it is suitable for many occasions.
03.The cost is low, the equipment is popular, the compatibility is good, and the interface is flexible.
The disadvantages of the Lotus audio cable are:
01.Analog audio signals are limited in bandwidth and are lost during transmission, so they are not suitable for long-distance transmission.
02.Only stereo or mono signals can be transmitted, and multi-channel surround signals cannot be transmitted.
03.It may be affected by external electromagnetic interference or ground loop interference, which will affect the signal quality.
The Lotus audio cable is suitable for scenes that require simple and intuitive, low cost, and high compatibility, such as recording studios, radio stations, record players, etc.
Both the coaxial audio cable and the lotus audio cable can be used to connect different devices in the audio system, but the coaxial audio cable is more suitable for transmitting digital audio signals, and the lotus audio cable is more suitable for transmitting analog audio signals. Generally speaking, when choosing an audio cable, the following aspects should be considered:
01.The type, quality, characteristics, content, etc. of the audio signal to be transmitted.
02.The type, performance, cost, etc. of the equipment to be used.
03.The distance and environment of the required transmission.
According to different situations, you can choose the appropriate audio cable to achieve the best effect. Here are some suggestions for common scenarios:
01.If you need to transmit digital audio signals and the device supports digital audio input and output, you can choose a coaxial audio cable.
02.If you need to transmit analog audio signal, and the device only has analog audio interface, you can choose Lotus audio cable.
03.If you need to convert the digital audio signal to an analog audio signal, you can use a digital optical fiber coaxial to analog converter (such as: digital optical fiber coaxial to analog converter eKL-DAA) to convert the audio and then use the lotus audio cable to connect Audio.
