Operating AV receivers wirelessly is a growing trend that is advancing more and more thanks to the steady expansion of wireless connection technologies such as WLAN and Bluetooth for various systems. The manufacturers Denon, Yamaha, Pioneer, Marantz and Sony, for example, rely on this with their products.

AV receiver wireless

Multiroom or voice control as a wireless function

The advance of speakers and voice assistants reduces the number of required cables to a minimum. This means a high gain in comfort, because the already high number of cables is reduced. The Bluetooth transmission standard has paved this way. For example, the first loudspeakers were equipped with this data transmission method.
The new multi-room systems set a new standard with the wireless connection options. WLAN is used here as the basis for enabling communication between the home theater control center and individual speakers and subwoofers.
The power supply of the individual components of the speaker system works via integrated batteries. This makes positioning easier, because there is an unusually high degree of flexibility.

Certainly, the Multiroom application is a special case in the context of sound transmission in this respect. Now, the fact is that a classic surround system like 5.1 has a fixed place to create a fully comprehensive sound in the room.
The need for speaker cables results from the permanent space occupied by the individual speakers. Before placement, the integrated measuring technology measures the individual distances between seats in the home theater, distance to the AV receiver and distance between the individual speakers.

If no measurement technology is available, these steps must be carried out manually. Moving the speakers, if they were operable via battery, would equalize the performed calibration. Besides the Multiroom application, common voice assistants like Alexa or Siri act as a measure to operate AV receivers wirelessly. The communication of the individual components of the home theater system is done via app and is theoretically realized via Bluetooth, practically rather via WLAN. Besides Yamaha MusicCast speakers, Sonos is one of the popular components that help to operate an AV receiver wirelessly*. Meanwhile, there are even wireless subwoofers.
