NOTES:
• Multi-channel audio does not include audio processing when it is sent to the
output. It is also unaffected by volume control.
• Auto modes default to digital audio. If digital audio is not available, then the
unit outputs analog audio.
• HC 404 can only de-embed digital 2Ch PCM audio to the analog audio
output. It cannot de-embed multi-channel audio.
