Audio De-embedding from SDI
In addition to audio channels input to MFR-16ADI, embedded audio channels input to
MFR-16SDI/16SDIA can output from MFR-16ADAO by de-embedding audio from SDI
signals.
SDI-embedded audio should be set in the [Web-based Control: Audio Settings page].
Note that embedded audio should meet the following requirements. Otherwise, audio
output should be choppy or noisy.
- Audio signals at 48kHz sample rates.
- HD-SDI embedded audio signals that are synchronized to the external reference signal
(REF IN2 input). 3G and SD SDI embedded audio signals are not properly synchronized.
MUTE
Mute can be enabled or disabled for stereo pair (2 channels).
Mute should be set in the [Web-based Control: Audio Settings page].
Digital-to-Analog Conversion
8 channels (4 stereo pairs) can be converted and output as analog audio. Audio level and
gain can be set for each stereo pair.
Audio level and gain should be set in the [Web-based Control: Audio Settings page].
Selects 4 stereo pairs (8 channels) output as analog audio
from the AES/EBU output channels.
Sets analog signal output level for each channel.
Audio output level is determined by the digital input level and
this setting as shown in the table below. Maximum output
level is +24dBm.
Adjusts signal gain for each channel.

Analog Audio Connection
For balanced audio signals, connect the hot, cold and shield conductor to "+" ," - " and
"COM" pins respectively.
For unbalanced audio signals, connect the conductor that carries audio to a "+" pin and
ground to "COM."
