What does D in Samsung Soundbar Means? [Detailed-Guide]

Have just bought a Samsung soundbar, and you are wondering, what does that D.IN written on the input section of your soundbar mean?

Well, you are not alone, a good percentage of folks get confused about what does that means, what it is exactly used for.

If that rings a bell, then we have a piece of good news for you. In this blog post, we have thoroughly discussed the function of D.IN mode, whey it is used for, and how it is different from the conventional input.

That being said, let’s jump right into the details.

What is the Function of D.IN Mode on a Samsung Soundbar?

So, you have seen the D.IN input on the backside of your Samsung soundbar, and you are wondering what is the purpose of this mode on the soundbar, and how it is different from the conventional input on the soundbar.

Firstly, the D.IN means Digital Input, although the terminology is a little bit strange, however, it is how it is. The Digital Coaxial Input on the soundbar allows you to have a digital connection on the soundbar using an optical connection.

The core function of this mode is to send the audio input signal from the TV (or any other source) to the soundbar in the digital audio. Thus, the quality of the audio transmitted via the D.IN mode is of much higher quality, and you can easily feel it in the sound of your soundbar. It’s the reason this input type is preferred over the other input types.

Is the D.IN Input Different From Conventional Mode?

The next thing that you may have in mind, is the Digital Optical Mode (also known as the D.IN) mode different from the other modes? The short and sweet answer is a “Yes”, this mode is different from the RCA input, HDMI, and the AUX. Below, we have discussed in detail the differences, and similarities between all of these input types.

Optical Vs HDMI Vs Aux (3.5mm): Which One is Better?

Optical, HDMI, or AUX, which one is better and why, this debate has been here for a while now, you will witness this question over and over again in different audiophile forums, and with this detailed comparison, we will put it at rest.

Firstly, there is the AUX input, which is an analog input, thus the signal quality is not as good as the two former connection types given below. The fidelity of these connection types makes it inferior to the HDMI or optical connection, as you cannot carry Dolby Atmos DTX signal with this connection type. The only benefit of using this connection over the other two connections is that you can connect the 3.5mm jack to laptops, and mobile phones, which is absolutely amazing.

The HDMI connection is another reliable way of connecting the soundbar to an audio source. There are various benefits of using the HDMI connection over the conventional RCA or AUX connection, as it’s a digital audio format, and carries digital signals.

Since the HDMI carries digital signals, thus it is compatible with the Dolby Atmos, Dolby DTI, etc. Alongside, it also supports 5.1 channels, and 7.1 channel audio. If you are using Blu-ray or another hi-fi system, you have to use the HDMI connection to get the best audio fidelity. Also, using this connection type is super-quick, and easy. You can easily use the HDMI connection using a single HDMI cable. The only downside that you may have to face with the HDMI connection is that it does have interference with electrical and ground, which may be annoying at times.

The most recommended type of audio connection that you can use with the soundbars is the D.In or the optical connection. Just like the HDMI connection, this connection type works in digital format. So, it is compatible with the Dolby Atmos, & Dolby DTS:X connection types, which is absolutely amazing.

Interestingly, it also has support for 5.1 channel and 7.1 channel sound, and unlike the HDMI connection, it does not have any interference with the ground or electrical appliances. The only thing people do not like about digital optical sound is its complexity of usage.
