Operation Controls and Functions
Left Panel
| No. | Name | Function Description |
|---|---|---|
| 1 | Power LED | Red LED will be on when the device is powered on. |
| 2 | DC 5V | 1) DC 5V power supply port. 2) Firmware update port. |
| 3 | eARC switch | The switch is used to turn on/off the eARC function: Switch to "ON" position — the AUDIO OUT2 port will output the eARC/ARC audio. Switch to "OFF" position — the AUDIO OUT2 port will output the audio from the HDMI IN port. |
| 4 | EDID switch | The switch is used to select EDID setting: Switch to "OUT1" or "OUT2" position — the product will copy the corresponding EDID from the device connected to OUT1/OUT2 port. If the copy fails, it will use the internal EDID defaulting to 1080p 2CH. |
| 5 | INPUT port | HDMI signal input port, connected to HDMI source device. |
Right Panel
| No. | Name | Function Description |
|---|---|---|
| 1 | eARC/ARC OUT 1 | TV eARC/ARC audio output port. Connect to TV with eARC function. |
| 2 | AUDIO OUT 2 | HDMI audio output port, connected to amplifier or speaker. When the eARC function is disabled, this port outputs a 720p black screen and the audio extracted from the HDMI IN port. When the eARC function is enabled, this port outputs a 720p black screen and the eARC audio returned from the eARC/ARC OUT 1 port. |
Application Example
Mode 1: eARC / ARC Application
Notes:
1. It is recommended not to connect any device to the INPUT port.
