3.2 Connecting to Devices

The BTR17 offers three primary connection modes: PC (USB DAC), BT (Bluetooth DAC/AMP), and PHONE (Smartphone Tail DAC/AMP). Use the physical switch on the side of the device to select the desired mode.

3.2.1 Bluetooth Mode (BT)

1. Switch the mode selector to "BT".
2. On your source device (smartphone, tablet, etc.), enable Bluetooth and search for available devices.
3. Select "FiiO BTR17" from the list to pair.
4. Once paired, audio from your source device will be transmitted wirelessly to the BTR17.

3.2.2 PC Mode (USB DAC)

1. Switch the mode selector to "PC".
2. Connect the BTR17 to your computer using the USB-C cable.
3. The computer should recognize the BTR17 as an audio output device. Select it in your system's sound settings.
4. For optimal performance, FiiO may provide specific drivers for Windows. Refer to the FiiO official website for driver downloads if necessary.

3.2.3 PHONE Mode (Smartphone Tail DAC/AMP)

1. Switch the mode selector to "PHONE".
2. Connect the BTR17 to your smartphone using a compatible USB-C to USB-C cable (or appropriate adapter).
3. The BTR17 will function as an external DAC/AMP for your smartphone.

3.3 Desktop Mode (D.Mode)

The BTR17 features a dedicated Desktop Mode (D.Mode) switch. When activated and an external power supply is connected to the dedicated power input (Sub Type-C port), the BTR17 will draw power directly from the external source. This prevents the internal battery from being used, charged, or discharged, and allows for maximum power output (up to 650mW) without draining the connected smartphone's battery.

4. Operating Instructions

4.1 Power On/Off

Press and hold the power button (usually located on the side) for a few seconds to turn the device on or off.

4.2 Volume Control

Rotate the multi-function knob to adjust the volume. The knob can also be pressed for various functions depending on the context (e.g., play/pause, menu navigation).
