No wires, no problems, just plug in an A/V transmitter.

What is an A/V transmitter?

A.V transmitters are designed to eliminate wires between your devices. They transmit an audio signal from a source device to a destination. For example, an A/V transmitter would let you stream audio wirelessly from a TV to a Bluetooth speaker.

How do A/V transmitters work?

A/V transmitters work by converting the signal from one device into a digital signal that is then transmitted wirelessly to a receiver on another device. The receiver decodes the signal so the audio can be played.

When used with a smartphone or device that already supports Bluetooth, then a receiver plugs into a destination device (for example an older stereo system) so it can play music streamed from the smartphone.

What are the best uses for A/V transmitters?

A/V transmitters are best used to eliminate unwanted wires. They keep your audio setup clean, so there are fewer cables to hide or trip over. They are ideal for adding wireless audio/video capability to a device that lacks the built-in capability. They also allow you to listen to music at a distance, without having to patch together a series of extension cables.

One of the classic examples is using a Bluetooth transmitter that connects to a TV to stream audio wirelessly to a pair of Bluetooth headphones. This lets you watch TV at night without worrying about disturbing other people. Another great use is plugging a Bluetooth receiver into the AUX input of an older car stereo. This lets you stream music from a smartphone over the car stereo.

There are also A/V transmitters that can wirelessly send and receive video signals. This sort of solution would let you wirelessly connect a DVD player or laptop to your TV.

What A/V transmitter is best for me?

When choosing an A/V transmitter, there are several factors to consider to make sure you get the best one for your situation.

The first consideration is whether you want to wirelessly connect a video source, or just audio. If video, make certain the connection standards supported by your devices are included (this will usually be HDMI).

Audio is the most common application of the technology. With a Bluetooth transmitter you will primarily be focused on the connection port used by the transmitter and/or receiver. These need to match the intended devices, and will usually be 3.5mm AUX jacks, or USB, although some solutions may offer optical, HDMI, or RCA connectors.

Finally, check the A/V transmitter for range. You want to make certain the signal will be strong enough to reach the required distance.
