A Bluetooth® audio transceiver is typically a small device that allows you to play digital audio from any number of devices through a stereo system. Many products with different designs and features offer users and audio enthusiasts the ability to transmit audio signals wirelessly from small devices to larger ones, such as home or car stereo systems. These components can vary in terms of their individual capacities, signal strengths, and hardware capabilities. Compatibility with multiple digital formats and technology products requires an assessment of the specifications of your devices and your audio needs. Features to consider when selecting the best Bluetooth® audio transceiver include size, design, quality, range, and power consumption.
Quality of construction as well as user reviews and reports may influence your choice. Compatibility with intended devices may factor in, as well as compromises in audio fidelity and signal bit rates versus degradation of high-end audio in the compression process within the Bluetooth® bandwidth. Whether you are drawn by vivid colors or technical power, there is likely a Bluetooth® audio transceiver designed expressly for your purposes and within your price range.
Typically a small handheld dongle, or desktop device, a Bluetooth® audio transceiver may be fitted with various ports or jacks for compatibility with equipment such as laptop computers, cell phones, or stereo systems. Digital audio formats such as Moving Picture Experts Group Audio Layer 3, or MP3, MPEG-4, compact disc, or other digital signals are transmitted between other digital media devices; compatibility between devices is fully preserved, while quality of compression coding or interference can sometimes degrade the signal. These signals may be transmitted through a single transceiver to one or more media players located around a home. As long as the Bluetooth® device is within range, wireless signals can be broadcast conveniently from a player to a separate transceiver located elsewhere, and into a speaker set-up, without any use of wires or cords. It should be noted that digital formats usually compress audio, resulting in slightly reduced quality through a stereo system, compared to playing from a compact disc directly.
Generally, a transceiver is a device that transmits and receives digital signals, such as those from a compact disc or a computer file. Bluetooth® audio transceiver devices combine the capabilities of dedicated receivers or transmitters, so it's important to determine which type you specifically need. Furthermore, devices might be limited in how many signals they can process at one time. Consider how many other people may want to use the device at the same time, where they may be located, and your combined bandwidth needs.
Households might benefit from a transceiver capable of processing multiple streams while preserving audio quality against interference dropouts. These units are typically capable of converting digital and analog signals for compatibility with more traditional equipment, as well as the latest mobile devices. They may be subject to dynamic range limitations from signal amplifications and receiver outputs — that is, the power limitations of each component.
The Bluetooth® wireless protocol permits simultaneous broadcasting by separating signals throughout available channels. Some equipment may feature more powerful antennas, audio cables, and alternating current (AC) adapters in order to better service residential needs. Other handheld or remote devices might feature electronic readouts, player controls, or cigarette lighter jacks suitable for use in a vehicle. Wireless transmission can quickly absorb battery power, so including alternative power sources for remote uses may serve your needs.
Devices may be designed for use with portable or console video gaming equipment, personal digital assistants, and televisions. Certain types are limited to battery power, while others come with their own docking stations or are able to plug into a computer Universal Serial Bus (USB) port. Consider the compatibility issues with your preferred equipment and audio environment in order to best select a device that can accommodate your desired set-up.
