Let's compare Samsung HW-Q900T and VIZIO SB3621n-F8M for an overview of all their audio functions. And according to the comparison results, we can see that HW-Q900T is superior to SB3621n-F8M in quality and number of functions. According to the results of our comparison, HW-Q900T received 8.2 points out of 10 possible, and SB3621n-F8M was rated 4.6 points.
The HW-Q900T is rated 8 of 10 against 6 for the SB3621n-F8M according to the audio features rating.
It worth understanding the difference between the two types of amplification: a passive soundbar does not have its own amplifier and receives amplification from the signal source, while an active soundbar has a built-in amplifier. The same active type of amplification is used in the HW-Q900T and the SB3621n-F8M.
There are stereo soundbars and multichannel ones. It is with the help of multichannel devices that you can get volumetric sound. It is worth noting one of the main differences, the HW-Q900T has 7.1.2 channels, while the SB3621n-F8M has 2.1 channels.

Unlike stereo, when reproducing multichannel sound, each specific direction of sound corresponds to its dedicated channel with a separate independent loudspeaker, which creates a three-dimensional sound stage. The HW-Q900T received rating 9 out of 10 for multichannel audio processing, but the SB3621n-F8M, in the same category, earned 4 out of 10 points.
The peculiarity of Dolby Atmos is that this format is object-oriented, that is, each object of the audio signal is sounded separately and linked to its spatial location. Dolby Atmos surround sound support is implemented only in Samsung HW-Q900T.
DTS:X is an algorithm for processing sound scenes by the processor, linking directly to objects, rather than channels, and calculating the optimal distribution of sound output in a room. The manufacturer has implemented DTS:X technology only in HW-Q900T.

The existence of a sufficient number of current connectors significantly expands the functionality of the device. For example, only through HDMI is it possible to implement the transfer of object-oriented formats, and the presence of a Bluetooth connection will allow remote control, etc. The devices received different ratings for connectivity: Samsung HW-Q900T was rated 8 out of 10, and VIZIO SB3621n-F8M was rated 4 out of 10.
The presence of Wi-Fi in the soundbar allows you to get rid of wires when connected to a sound source and get minimal audio latency when playing content from streaming services. Wireless connection via Wi-Fi is possible on the HW-Q900T.
Bluetooth connection is now one of the main communication protocols for speaker systems, which provides excellent quality and minimal audio latency. The availability of Bluetooth protocol, we can see in both models.
HDMI ARC is a very usefull technology that creates a two-way communication channel between a TV and another device. This is convenient since there is no need to use optical and other cables in the system. HDMI ARC is a feature unique to Samsung HW-Q900T.
