Audio Configuration (All Models)

Audio Configuration allows the user to set volume level (0 dB to -100 dB range), turn audio mute on or off, adjust input gain and attenuation levels (–53 dB to +9 dB range) for the current analog input. It also allows selection of an input audio format (none, analog,

2-channel digital, full digital, 2-channel auto, or full auto), and the audio output type (stereo or dual mono), which can be adjusted for each input.

NOTE: Volume level and input gain and attenuation adjustments are only available on
audio models (DVS 605 A and DVS 605 AD).
• For analog inputs 1 and 2, the choice of input audio format is analog or none.
• For non-audio models format selection for inputs 3 through 5 is limited to
none, 2-channel digital, or full digital.
• For inputs 3, 4, and 5, when in auto mode, digital audio is used when
present. If no digital audio is present it defaults to analog audio.

Input Audio Format

Description

None	All audio for the input is muted: 128 byte EDID (VGA/DVI) is presented to the source.
Analog	5-pole captive screw connector is used for audio input: 128 byte EDID (VGA/DVI) is
	presented to the source.
2-channel digital	256 byte EDID (HDMI) is presented to the source requesting 2CH PCM audio.
Full digital	256 byte EDID (HDMI) is presented to the source allowing for all digital audio formats.

NOTE:	DVS 605 anlog audio outputs are active only if analog or PCM audio is detected on HDMI
inputs 3,4, and 5.

2-channel auto	256 byte EDID (HDMI) is presented to the source requesting 2CH PCM audio.
	If digital audio is not present this automatically defaults to the 5-pole captive screw
	analog audio input.
Full auto	256 byte EDID (HDMI) is presented to the source allowing for all digital audio formats.
	If digital audio is not present this automatically defaults to the 5-pole captive screw
	analog audio input.

Audio Delay Setting

The DVS automatically delays all analog and digital audio inputs to compensate for internal video processing delay. Occasionally additional audio delay is required to account for other signal processors, scalers, or display devices in a system. For these situations, the DVS 605 offers an additional 0-255 ms static global audio delay which can be set via SIS command or internal web pages to eliminate audio “lip sync” issues.
