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.

NOTE: The Lock LED indicates valid input video by color. Green is SD video, red is HD video, off is

no input.
