Matters needing attention:
1. Please use standard HDMI cable and connect the cable before powering the equipment.
2. The output port OUTA can output audio only. Connect OUTA to the HDMI input port of the audio device (Power amplifier, Soundbar…) by an HDMI cable.
3. The audio output of the audio ports can be turned on/off by using the "SPDIF" key on the remote control.
4. Analog audio can only be output when the audio format is LPCM, so it is recommended to choose the EDID mode in 2CH mode when using analog audio output.
5. If you want to use ARC or CEC, you must connect the TV to the OUTB port. Before using ARC, make sure your TV HDMI port supports ARC and the ARC have been turned on.
6. The product has power off memory function. The setting state of the output channel is recorded and saved. After the power is off, the saved data will be automatically retrieved for configuration.
