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 Mini-Config 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.
