BTA 30 users can select 3 different switch buttons corresponding to 3 different usage modes:
- BT RX mode (Bluetooth Receiver): This product will work like other Bluetooth Receiver on the market today. Receive signals from source devices such as music players and output analog RCA or Optical/Optical ports
- DAC mode: This is a fairly simple name when the product will receive digital signals from Coaxial and Optical ports (such as from TV or CDP) to export to analog RCA ports.
- BT TX mode (Bluetooth Transmitter receiver): This is the mode that many users expect. The user transmits digital signals into Coaxial and Optical ports and then decodes and emits Bluetooth to the wireless headphone and speaker devices.
