HA5 Simplified Block Diagram
Audio
HA5 Mini-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. However, if audio is not synchronous with video or the sample rate
is not 48 KHz, then jumper #1 must be installed. Having jumper #1 installed forces an
onboard Sample Rate Converter to convert audio to 24-bit/48 KHz and then synchronize
it with input video before embedding. In this scenario only channels 1/2 are
embedded—the other 6 channels are muted.
