HiBy FC5 Display Setup for Headphone Amp Output

Quick answer

Connect the HiBy FC5 to your source via USB, select the correct output mode on the display, and adjust the volume with the physical knob for optimal headphone amp performance.

Setting up the HiBy FC5 for headphone amp output

1. Connect the FC5 to your source: Use the included USB cable to connect the FC5 to a computer, smartphone, or tablet. The display will light up and show 'USB Audio' mode. If the display stays off, check the cable connection and try a different USB port.
2. Select the correct output mode: Press the mode button on the side of the FC5 until the display shows 'Headphone Amp' (not 'Line Out'). The amp output is designed for headphones with a 3.5mm jack. Using 'Line Out' with headphones can produce a very quiet or distorted signal.
3. Adjust the volume with the physical knob: Rotate the volume knob clockwise to increase volume and counterclockwise to decrease. Start at a low level and gradually increase to avoid sudden loudness. The volume knob controls the amplifier gain; setting it too high with sensitive IEMs may cause hiss.
4. Verify the sample rate on the display: Check the display shows the correct sample rate (e.g., 44.1kHz, 192kHz, or DSD). If it shows an unexpected rate, adjust the source device's audio settings. Mismatched sample rates can cause stuttering or no audio output.
