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 SR-C20A and the Shockwafe Pro 7.1 eARC.

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 SR-C20A has 2.1 channels, while the Shockwafe Pro 7.1 eARC has 7.1.4 channels. Also, the output power of the soundbars under consideration is different, Yamaha SR-C20A has 100 (overall) W, and 850 (overall) W has the competitor.

Subwoofers

Soundbars can have a built-in or external subwoofer. The first type is inseparable from the soundbar body, but for the second, you can choose a good location for deep bass. A built-in subwoofer is only present in the SR-C20A. The Shockwafe Pro 7.1 eARC comes with an external subwoofer.

Multichannel surround

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 SR-C20A received rating 6 out of 10 for multichannel audio processing, but the Shockwafe Pro 7.1 eARC, in the same category, earned 10 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 Nakamichi Shockwafe Pro 7.1 eARC.

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 Shockwafe Pro 7.1 eARC.

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. Such connection as via Wi-Fi is not possible on any of the devices in comparison.

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. The SR-C20A has 0/1 HDMI inputs/outputs, but the Shockwafe Pro 7.1 eARC got 1/1 HDMI inputs/outputs from the manufacturer.

HDMI ARC is a very usefull technology that creates a two-way communication channel between a TV and another device.
