The BTA-2 is a Bluetooth transmitter/receiver that allows you to connect your phone wirelessly to record interviews with remote participants. Once the connection is established, you can use any application such as Skype, Zoom, phone, and many others to invite guests from afar for an interview for your podcast. The BTA-2 features two ports: a 3.5 mm TRRS port for the audio signal on the right side and a 2.5 mm TRRS power supply port on the left side. Thanks to the easy setup, you can start recording in no time.
