6. Operation

6.1. Input Switching

• Manual Switching: Press the SWITCH button on the front panel or the corresponding input button on the remote control to cycle through the HDMI inputs (IN 1-4). The active input indicator will light up.
• Automatic Switching: Press the AUTO button on the front panel or remote control to enable/disable automatic input switching. When enabled, the AX341 will automatically detect and switch to the most recently activated source device. Note: Automatic switching may not be fully compatible with all devices (e.g., Apple TV or Xbox).

6.2. eARC Audio Extraction

• The AX341 can extract eARC/ARC audio from either HDMI OUT 1 (TV1) or HDMI OUT 2 (TV2).
• Press the eARC button on the front panel or remote control to select which TV's audio return channel should be used for extraction. The corresponding TV1 or TV2 eARC Audio indicator will light up. This is particularly useful when switching between a TV and a projector.
• The extracted audio will be available on the HDMI OUT 1 (eARC/ARC), Optical TOSLINK, and 3.5mm analog audio outputs.

6.3. CEC Control

The AX341 supports CEC (Consumer Electronics Control), allowing for integrated control between compatible devices. This enables functions such as:

• Controlling the volume of your soundbar using your TV's remote control.
• Automatic power-on/off of connected devices (e.g., the AX341 powering on with your TV).

Ensure CEC is enabled on all connected devices (TV, soundbar, source players) for this functionality to work.

8. Troubleshooting

If you encounter issues with your FeinTech AX341, please refer to the following common troubleshooting steps:

• No Video/Audio Output:
  • Ensure all HDMI cables are securely connected to both the AX341 and your source/display devices.
  • Verify that the correct input is selected on the AX341 (check input indicators).
  • Confirm that your display is set to the correct HDMI input.
  • Try different HDMI cables, as faulty cables can cause signal issues.
  • Bypass the AX341 by connecting a source directly to a display to isolate the problem.
  • Restart all connected devices, including the AX341, by unplugging them from power for 30 seconds and then reconnecting.
• Audio Issues (No Sound, Distorted Audio):
  • Check audio connections to your soundbar or AV receiver (HDMI eARC/ARC, Optical, 3.5mm Jack).
  • Ensure the correct audio input is selected on your sound system.
  • If using eARC, verify that eARC is enabled on your TV and the AX341 is set to the correct TV's eARC audio (TV1 or TV2).
  • Confirm that the audio format from your source device is supported by your sound system and the AX341's audio extraction ports (e.g., TOSLINK only supports stereo or Dolby Digital).
  • Adjust volume levels on all devices.
• Automatic Switching Not Working:
  • Ensure the AUTO function is enabled on the AX341.
  • Note that some source devices (e.g., Apple TV, Xbox) may not fully support automatic switching.
  • Try manually switching inputs if auto-switching is unreliable.
• CEC Control Problems:
  • Verify that CEC (often called Anynet+, Bravia Sync, SimpLink, etc.) is enabled on your TV, soundbar, and source devices.
  • CEC functionality can be inconsistent between different brands and models.
• Resolution/Picture Quality Issues:
  • Ensure your HDMI cables are rated for HDMI 2.1 and support the desired resolution (e.g., 8K or 4K@120Hz).
  • Check the resolution settings on your source device and display.
  • If using the downscaler, ensure it is functioning as expected for 1080p displays.
