6. Arahan Operasi

This section details how to use the various features of your HDMI Matrix Switch.

6.1 Input/Output Switching

You can switch inputs for each output independently using the front panel buttons or the IR remote control.

• Butang Panel Depan: Press the "HDMI OUTPUT1" or "HDMI OUTPUT2" buttons repeatedly to cycle through the connected HDMI inputs (1-4) for the respective output.
• Kawalan Jauh IR: Use the numbered buttons (1-4) under "HDMI OUTPUT1" or "HDMI OUTPUT2" on the remote to directly select the desired input for each output.

6.2 Pengurusan EDID

The EDID (Extended Display Identification Data) switch on the rear panel allows you to manage how the source devices detect the display capabilities. This is crucial for ensuring compatibility and optimal audio/video formats.

• 4K7.1: Forces the EDID to report support for 4K resolution with 7.1 channel audio (e.g., Dolby Atmos, DTS:X).
• 4K5.1: Forces the EDID to report support for 4K resolution with 5.1 channel audio.
• SALINAN: Copies the EDID from HDMI OUT1. This is useful if you want the source to detect the exact capabilities of your primary display.

Nota: Change EDID settings while the device is powered on, then restart source devices for changes to take effect.

6.3 4K to 1080P Down-Scaling

Imej: A terperinci view of the Scaler DIP switches, labeled 1 and 2, for controlling 4K to 1080P down-scaling for each output.

The matrix switch can down-scale a 4K source signal to 1080P for displays that do not support 4K resolution. This allows 4K and 1080P TVs to work simultaneously.

• Use the DIP switches labeled "SCALER" on the rear panel.
• Switch 1 controls down-scaling for HDMI OUT1.
• Switch 2 controls down-scaling for HDMI OUT2.
• Set the switch to "ON" (1080P) to enable down-scaling for the respective output. Set to "OFF" (PASS) to pass the original 4K signal.

Nota: Down-scaling applies only to 4K to 1080P. It does not down-scale 4K HDR Dolby Vision (4K60Hz 4:2:2) or VRR signals.

6.4 Audio Return Channel (ARC) and Consumer Electronics Control (CEC)

Image: Two diagrams showing how CEC and ARC function with the HDMI Matrix Switch. The top diagram shows CEC enabling audio output to headphones or speakers from HDMI OUT1. The bottom diagram shows ARC allowing audio from the TV connected to HDMI OUT1 to be sent back to the SPDIF output.

HDMI OUT1 supports ARC and CEC functionalities. These features are mutually exclusive; only one can be active at a time.

• ARC (Saluran Pulangan Audio): Allows audio from the TV connected to HDMI OUT1 to be sent back to the matrix switch's SPDIF output. This is useful for playing TV's internal apps audio through an external sound system. Select "ARC" using the "Optical Out Select" switch.
• CEC (Consumer Electronics Control): Enables control of connected devices through a single remote. When "CEC" is selected via the "Optical Out Select" switch, audio from HDMI OUT1 can be stripped and sent to the L/R 3.5mm output.

Nota: ARC is supported via the SPDIF port. This device is not compatible with Sonos ARC. Ensure your TV and connected audio devices also support ARC/CEC for these features to function.

6.5 Pengekstrakan Audio

Image: Diagram illustrating the different audio output formats: 2.1CH via HDMI, L/R OUT, SPDIF OUT; 5.1CH via HDMI, SPDIF OUT, ARC; and 7.1CH via HDMI Amplifier Dolby Atmos Soundbar. It notes that two different channels cannot be output simultaneously.

The matrix switch can extract audio from the HDMI signal and output it through dedicated audio ports.

• SPDIF/Optical Out: Provides 5.1CH digital audio, following the audio from HDMI OUT1.
• L/R OUT (3.5mm): Provides 2.1CH stereo audio, suitable for headphones or stereo speakers.

Nota: The device does not support simultaneous output of ATMOS 7.1 and 5.1 audio. It is not an audio down-mixer.
