HDMI Wall Plate with Audio Extraction

Similar to Video EDID, you can control how the parts of the EDID table

that pertain to audio capabilities are constructed. Clicking these controls

selects either PASS-THRU, 2 CHN or MULTI modes

AUDIO EDID

2 CHN – EDID from SINK is set for 2 channel LPCM audio with 2 speakers.
MULTI – EDID from SINK is set for LPCM, DTS and Dolby audio with multiple speakers.
PASS-THRU – EDID from SINK is used
2-Channel is the FACTORY DEFAULT setting. Since the VSA-51 has a stereo 2-channel

audio amplifier, it is best to have the EDID set for two channel regardless of what is

connected downstream.

EDID Routing Modes

On HDMI output

Mute Audio

Clicking this control removes the audio portion from the HDMI video output (on the VSA-

51 HDMI output connector). You can use this command to make sure no audio comes

out of the display's built-in speakers.
FACTORY DEFAULT is not muted.

Cycle HPD

Misc

Clicking this control sends causes a 0.5 second pulse on the

Hot Plug Detect signal that is sent to the video source. So

basically the source will see an unplug and a re-plug. It has the

same effect of unplugging the HDMI input cable and plugging it back in. This forces the

source to re-initialize its HDMI video output connection (read EDID, and implement

HDCP if required) This indicator is ‘filled green’ when the source is connected.
