Connection and operation:
Please note:
- Please use standard HDMI cable and connect the cable before powering the equipment.
- Please preferentially connect 8K TV to OUTB. OUTA outputs 8K@60 or 4K@120 resolution only in split mode (In this mode, OUTA and OUTB select the same input source). The maximum output resolution is 8K@30 or 4K@60 in other modes.
- 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.
- The AUDIO OUT is a set of multiplexed ports that allow you to select HDMI OUTA/B sounds by using the “A-B” key.
- The Audio EDID mode selection is also available for multiplexed. When the audio source selects channel A, the audio EDID mode is valid for channel A. When the audio source selects channel B, the audio EDID mode is valid for channel B.
- 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.
- If you want to use ARC or CEC, you must connect the TV to the OUTA port. Before using ARC, make sure your TV HDMI port supports ARC and the ARC have been turned on.
