Transmitter/receiver audio Bluetooth 5.0 AUX RCA - PLUGGER STUDIO BT 7RT

The PLUGGER STUDIO BT 7RT is a compact Plug & Play Bluetooth 5.0 audio transceiver, compatible with a wide range of audio devices and equipped with numerous functions and connectors. In receiver mode, it can make any audio device wireless by connecting it to the BT 7RT's 3.5 mm or RCA AUX output. Audio files can then be streamed from a smartphone, tablet, computer or any other device with Bluetooth connectivity; the wirelessly received signal is converted into analogue audio output.

In transmitter mode, the operation is reversed: a conventional device such as a turntable, TV or video projector can be converted into a wireless source for Bluetooth 5.0 receivers, including speakers and headphones. The integrated microphone enables hands-free use, phone-call management and compatibility with vehicle navigation systems. Its built-in 3.7 V, 400 mAh lithium-polymer battery provides 6–8 hours of uninterrupted music, including while charging.
