2-4. Audio Input / Output Cards
Source and destination assignment procedures for audio signals are the same as those for SDI
signals. Refer to Sec. 2-3. “SDI Input / Output Cards.”
This chapter describes audio specific setup. Audio signals should be setup in the Web-based
Control pages
► See [Web-based Control: Audio Settings page].
2-4-1. MFR-8AAI (Analog Input)
MFR-8AAI is an analog audio input card with A/D converter.
Up to 8 cards can be installed into Slot No. 01 to 08.
► See “Input /output cards and Slots” in Sec. 2-2. "MFR-3100EX Rear Panel."
25-pin D-Sub (female) x 2 (8 stereo pairs, 16 channels), 600-ohm or high impedance
◆ Analog Audio Input
Select the input impedance and adjust the input level per each stereo pair (2 channels) in the
[Web-based Control: Audio Settings page].
Analog Input Terminal
Select 600-ohm or High impedance for analog audio
input.
Analog Input Termination
(*1)
Analog Input Level
Select the analog audio input level for each stereo pair.
Analog Input Ref Level
(*1)
Analog Input Adjust Gain
(*1)
Adjust analog input signal gain for each stereo pair.
(Settings: -20dB to 20dB
0.1dB steps for -3dB to +3dB and 1dB steps for
other range.)
Digital Output Ref Level
(*1)
Sets digital output reference level in A/D conversion.
(Settings: -20dBFS, -18dBFS)
(*1) MFR-8AAI FPGA version 1.02.0 or higher
◆ 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 "-" and "COM."
