Establishing the connection is easy: activate Bluetooth on the speaker and TV, pair them, and you're done.

Wireless base station transmits signal to external TV speakers

Base stations offer another wireless connection option, transmitting the audio signal from the TV to external wireless TV speakers. With this technology, the signal is sent wirelessly from the base station connected to the TV to the speakers. This type of transmission is particularly advantageous as it maximizes the flexibility of speaker placement without the need for cables. Unlike Bluetooth, which is often limited to shorter distances and smaller rooms, base stations offer greater range and more stable connections, making them ideal for larger rooms or for using speakers in different areas of the home. Audio quality also remains high, as the base station is specifically designed to deliver a strong and clear signal. This technology is a practical solution when the freedom of wireless speakers is desired without compromising sound quality.

HDMI ARC and eARC

HDMI ARC (Audio Return Channel) is one of the best options for lossless audio signal transmission. With ARC, both sound and control signals can be exchanged between the TV and speakers, simplifying operation. The improved version, eARC (Enhanced Audio Return Channel), even allows the transmission of high-resolution audio formats such as Dolby Atmos. These connections offer excellent sound quality and are particularly interesting for home theater systems.

Optical connection (TOSLINK)

The optical connection (also known as SPDIF) is a digital transmission method that enables loss-free and interference-resistant transmission of audio signals. TOSLINK transmits the signal via light waves, which prevents interference from electromagnetic influences. This connection is particularly useful if the TV does not offer Bluetooth functionality or if a more stable, interference-free connection is desired. The optical connection is ideal for older devices or for users who want precise sound reproduction without the complexity of wireless connections. Although the optical connection does not support the latest formats such as Dolby Atmos, it offers an excellent and reliable solution for many applications, especially when connecting to external TV speakers.
