You are probably familiar with Bluetooth. This technology was invented nearly a decade ago and is now being used by almost every smart phone and other portable device. This is not surprising because they are many applications. The main application for which Bluetooth was originally designed is to connect peripherals such as printers and tablets to computers. The Bluetooth with essentially replace the cable. Lately, Bluetooth has also been adopted for transmission of high-quality audio without wires.
In this post, I will show you how to use Bluetooth receivers in order to stream music to some speakers. Several manufacturers are offering products which are suitable for speakers. As an example, Amphony Bluetooth products can be connected to any passive speaker. Other types of Bluetooth receivers typically connect to either active speakers or audio amplifiers. The wireless range of either of these devices is usually fairly short. Typically, Bluetooth receivers will allow you to stream for distance of at least 30 feet. Some models extend the distance to up to 100 feet. However, achieving 100 feet distance with Bluetooth requires that both devices are within line of sight and that there is not any heavy wireless interference nearby.
Installing a Bluetooth audio receiver is pretty straightforward. Usually all that you need to do is establish power by plugging in the wallwart which is normally included with the package and then make a short cable connection between the receiver and the input of you speakers were amplifier. If you have a Bluetooth amplifier then most likely you will need some speaker cables in order to connect the amplifier to some speakers. Some models of fairly small and can be attached to the rear of the speaker to become totally invisible.
However, keep in mind that most likely your Bluetooth receiver or amplifier will offer to outputs. When mounting the receiver to his speaker, you will still need to string a wire between the receiver and the second speaker which might be located away from the first speaker. It is not possible to use multiple Bluetooth receivers in order to stream to two speakers without any special software. That is because you can typically only sink to a single receiver.
There are some Bluetooth speakers on the market which overcome this shortcoming by incorporating a wireless link such that one of the speakers can receive the Bluetooth signal and then transmit a signal to the second speaker by using a different wireless technology.
