Digital Decoding Mode (DAC) Setup
In DAC mode, the BTA30PRO acts as a high-quality digital-to-analog converter, taking digital audio input and outputting an analog signal to your audio system.
- Set the BTA30PRO to DAC mode using the MODE switch.
- Connect your digital audio source (e.g., computer, CD player, game console) to the BTA30PRO's USB, Optical, or Coaxial input.
- Connect the BTA30PRO's RCA, Optical, or Coaxial output to your amplifier or active speakers.
- Ensure your source device is configured to output audio to the BTA30PRO.

Operating Instructions
Mode Switching
Use the MODE switch on the front panel to cycle through the three operating modes: RX (Bluetooth Receiving), TX (Bluetooth Transmitting), and DAC (Digital Decoding).
Bluetooth Codec Indication
The STATUS light on the BTA30PRO indicates the currently active Bluetooth codec:
- White: LDAC
- Yellow: aptX HD
- Green: aptX LL (Low Latency)
- Purple: aptX
- Blue: SBC
- Cyan: AAC
In TX mode, you can short press the LL/HD button to switch between available Bluetooth codecs if connected to a compatible device.
Volume Control
The large knob on the right side of the unit controls the output volume. Rotate clockwise to increase volume and counter-clockwise to decrease. This allows for precise volume adjustment for both Bluetooth transmission and reception.

Connecting Two Bluetooth Devices (TX Mode)
The BTA30PRO supports connecting to two Bluetooth headphones/speakers simultaneously in TX mode:
- Connect the first Bluetooth device (e.g., headphone A) as described in the TX mode setup.
- Once connected, put the second Bluetooth device (e.g., headphone B) into pairing mode.
- On the BTA30PRO, hold the INPUT button for about 3 seconds until the STATUS light flashes alternately in red and blue again.
- The BTA30PRO will search for and connect to the second device. Both A and B lights will be on simultaneously when both devices are connected.

Maintenance
To ensure the longevity and optimal performance of your FiiO BTA30PRO, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the unit. Avoid using abrasive cleaners, solvents, or strong chemicals, as they may damage the surface.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable not connected properly; power adapter faulty. | Ensure USB Type-C cable is securely connected to both the BTA30PRO and the power source. Try a different USB port or power adapter. |
| Cannot pair Bluetooth device | BTA30PRO not in pairing mode; device too far; interference. | Ensure BTA30PRO is in pairing mode (STATUS light flashing red/blue). Move devices closer. Reduce interference from other wireless devices. |
| No sound output | Incorrect mode selected; cables loose; volume too low; incorrect input/output selected on connected device. | Verify BTA30PRO is in the correct RX/TX/DAC mode. Check all audio cable connections. Increase volume on BTA30PRO and connected audio system. Ensure correct input/output is selected on your amplifier/speakers. |
| Poor sound quality (Bluetooth) | Low-quality codec active; signal interference; source audio quality. | In TX mode, try switching to a higher-quality codec (LDAC, aptX HD) by short pressing LL/HD button. Minimize interference. Use high-quality audio files. |
| Cannot connect two Bluetooth devices in TX mode | Second device not in pairing mode; pairing sequence incorrect. | Ensure the first device is connected, then put the second device into pairing mode. Re-enter pairing mode on BTA30PRO by holding the INPUT button for 3 seconds. |
