5. 작동 모드

The device supports two primary operating modes, configurable via the EDID DIP switches and port usage.

5.1. 2x1 HDMI Switch Mode

In this mode, two HDMI source devices share one HDMI display. The device acts as a traditional HDMI switch.

• Connect two HDMI sources to HDMI IN1/eARC OUT1 and HDMI IN2/eARC OUT2.
• Connect your display to HDMI OUT.
• Use the 'Select' button on the device or remote control to switch between the two HDMI input sources.

5.2. 1x2 HDMI eARC Splitter Mode

This mode allows audio from your TV's eARC/ARC port to be sent to two eARC/ARC compatible audio devices simultaneously or selectively.

• Connect your TV's eARC/ARC port to HDMI IN1/eARC OUT1.
• Connect your primary eARC/ARC audio device to HDMI IN2/eARC OUT2.
• Connect your secondary eARC/ARC audio device to HDMI OUT.
• The EDID DIP switch setting (4th dial) determines if it acts as a splitter (simultaneous output) or a switch (selectable output).

6. EDID Configuration

The EDID (Extended Display Identification Data) DIP switches on the device allow you to configure audio output behavior and operating modes.

영상: Detailed table of EDID DIP switch settings for audio modes (TV, 2.0CH, 5.1CH, 7.1CH) and operating modes.

The 4th dial of the EDID DIP switch specifically controls the eARC functionality:

• 4th Dial UP ("0"): eARC Switch 2X1 Mode. In this mode, only one of the two eARC output ports (HDMI IN1/eARC OUT1 or HDMI IN2/eARC OUT2) will output sound at a time. You can switch between them using the 'TV Audio' button.
• 4th Dial DOWN ("1"): eARC Splitter 1X2 Mode. In this mode, the TV sound is transmitted to both eARC audio devices simultaneously for synchronized high-quality audio.

6.1. General EDID Settings

The first three DIP switches (1, 2, 3) control the audio EDID settings:

Note: "0" indicates the DIP switch is in the DOWN position, "1" indicates the UP position.

7. Important Notes for ARC/eARC Usage

• When using the ARC feature, both the TV and the audio device need to support ARC.
• When using the eARC function, ensure the soundbar is connected to either the HDMI IN1/eARC OUT1 or HDMI IN2/eARC OUT2 port.
• When the audio format is 7.1 channel, the coaxial and optical ports cannot output sound.
• Remember the 4th DIP switch setting: "0" (Down) for eARC Switch 2X1, "1" (Up) for eARC Splitter 1X2.
