What is the primary function of a wireless transmitter in an AV system?

The primary function of a wireless transmitter in an AV system is to send audio or video signals wirelessly. This process allows for the transmission of content over the air, enabling greater flexibility in the placement of audio and video equipment and eliminating the need for physical cables that can clutter spaces and restrict movement.

Wireless transmitters take the encoded audio or video signals and convert them into a format suitable for wireless transmission, which is then picked up by compatible receivers. This capability is essential in various applications, such as live events, presentations, and installations where mobility and accessibility are important considerations. The other options pertain to functions not associated with a wireless transmitter, such as receiving signals, converting formats, or amplifying sound.
