Audio
The HA5-Plus converter supports 8 audio channels (4 stereo pairs) at 24-bit/48 KHz which
it dis-embeds from HDMI and embeds into SDI. For proper embedding, audio must be
synchronous to video. If audio is not synchronous with video or the sample rate is not 48
KHz, then MiniConfig must be used to set the Sample Rate Converter to convert audio to
24-bit/48 KHz and then synchronize it with input video before embedding.
