Audio Configuration

The Audio Configuration page (see figure 25) provides information and control of the analog audio output. The controls do not affect embedded audio on the HDMI output.

Analog audio can be delayed or muted. A master gain control for the selected audio is provided.

Figure 25. Configuration - Audio Controls

The analog audio output format is displayed in the Audio Output panel. Click Stereo to maintain a 2 channel audio output. Select Dual Mono when there is only single channel source audio. Dual mono provides two channel output from a single channel input or mixes left and right channels and sends the mix to both the left and right outputs.

The audio delay control allows the user to achieve audio-to-video synchronization when timing differences occur between the audio and video streams. By default, the audio and video streams are synchronized (Audio Delay: = 0 mS). Audio delay is adjusted between +255 to -255 milliseconds.

•Positive delay results in audio lagging video by the set value.

•Negative delay results in audio leading video by the set value.

NOTE: The source input must be restarted for an audio delay change to take effect.

Output audio can be toggled on and off using the master Mute button.

A master level control graduated in 1 dB steps from -100 dB (full attenuation) to 0 dB (unity gain) to set or match output levels. Move the slider or enter a value in the field below the slider to adjust volume from 0 (maximum output) to -100 (no output).

Audio mute and level settings are retained through reboot or power cycle events.
