AV receivers 2.1 represent a possible appearance of audio channels in the context of AV receivers. However, not many of these models exist on the market.
The fact of functioning only stereo should not hide the existing functionalities. These receivers are also known under the widespread designation AV-Receiver Stereo*.
AV receiver 2.1
AV receiver 2.1 surround sound
AV receivers 2.1 operate two audio channels and a subwoofer. The placement of this AV receiver is very simple. There is room for one speaker each to the left and right of the screen, TV or projection screen. In addition to the two speakers, there is a subwoofer that is responsible for the low tones.
AV receiver stereo HDMI
The acronym HDMI stands for High Definition Multimedia Interface. This interface is now widely used as a unified method for an interface. This technology is built into most AV receivers as standard. The AV receivers 2.1 HDMI are no exception.
AV receiver 2.1 Internet radio
The AV receivers stereo have the convenient option of accessing the multitude of international stations worldwide via a stable Internet connection. Unlike conventional FM radio, the quality of data transmission is subject to fewer fluctuations; it is less susceptible to interference.
Bluetooth AV receiver 2.1
The industry standard Bluetooth is found in smartphones as well as in AV receivers 2.1, which is suitable for connecting to suitable speakers that have this technology. As already mentioned, an AV receiver 2.1 needs two speakers and a bass channel for adequate functionality. Although this means that the speakers have to be very close to the multichannel amplifier, cables can be saved by connecting them with Bluetooth. Any reduction of cables helps to reduce the temperature in the rack to the bare minimum. After all, too high a temperature can have a negative effect on the installed components inside the AV receiver stereo when it is running at full capacity.
AV receiver stereo WLAN
With regard to the speakers, the widespread and almost standard WLAN technology plays a significant role. Now, the fact is that wireless speakers can work either via Bluetooth or via WLAN or via both technologies equally. If the AV-Receiver 2.1* has WLAN, this has an equally positive effect on the required space, temperature and compatibility with wireless speakers.
