Switches
Mini Converter Audio to SDI’s switches provide the following settings:
Switch 8 - Analog Audio, AES/EBU Audio
Set switch 8 to OFF to select balanced analog audio, or to ON for digital AES/EBU audio input.
Switch 7 - Sample Rate Conversion, No Sample Rate Conversion
Set switch 7 to OFF to enable sample rate conversion, or ON to disable sample rate conversion.
This switch should almost always be set to OFF to ensure audio is embedded at the correct
sample rate for television.
When switch 7 is set to OFF this setting converts the sample rate of your analog or AES/EBU
audio and embeds audio into the SDI output at a sample rate of 48 kHz. When switch 7 is set to
ON, sample rate conversion is disabled and audio is output at the original sample rate of your
input audio.
Switch 6 - Audio Group Bit 1
Switches 6 and 5 are grouped together to provide four ON/OFF combinations. Having four
different combinations allows up to four analog audio channels, or eight AES/EBU audio
channels to be embedded in your SDI output.
Switch 5 - Audio Group Bit 0
See switch 6 description.
