Although a higher bitrate does not always automatically mean better quality, the attached diagram shows the ability of different codecs to transfer data.
Main Bluetooth receiver connections
Bluetooth receivers offer versatile interfaces that enable them to be connected to different devices and sound sources. In this section, we discuss the most common connections that bluetooth receivers have:
3.5 mm AUX audio:
Many bluetooth receivers have a traditional 3.5 mm audio connection, also known as an AUX connection. This allows the receiver to be connected to almost any audio source with a corresponding connection, such as phones, computers, portable players and older speakers. The 3.5 mm audio connection is an easy and common way to add a bluetooth connection to existing audio devices. For example, many cars do not have bluetooth support, but AUX is available. In this case, it is very easy to use AUX to add a bluetooth receiver to the car.
Optical connection (Toslink):
An optical interface is a digital interface that transmits an audio signal using light. Many of the more modern audio systems have an optical connection that enables high-quality audio transmission. Bluetooth receivers with an optical connection are an excellent choice for applications that require high-quality sound, such as home theater systems or listening to music.
USB connection:
Some bluetooth receivers have a USB connection, which provides a convenient way to connect the receiver to computers or other USB-supported devices. Through the USB connection, the receiver can be powered directly from the device, so a separate power source is not necessarily needed. In addition, the USB connection can also offer better sound reproduction, because the sound is transferred in digital form.
RCA connections:
RCA connectors are common analog audio connectors often used in audio-visual equipment such as televisions, DVD players, and amplifiers. Some bluetooth receivers offer RCA connections, allowing them to be connected directly to these devices and enjoy wireless audio transmission.
XLR connection:
XLR connections are professional audio connections that provide a balanced audio signal. XLR connections are common in studio equipment and sound systems. Some high-end bluetooth receivers may offer an XLR connection, which is especially suitable for professional use.
