8 Ethernet PoE+
Connects to a network switch or computer so you can change settings using
Blackmagic Teranex Setup. The Ethernet port also supports power over Ethernet.
9 SDI In
SDI video input BNC connector.
10 Optical Input and Output
Optical video input and output LC connectors via optional SMPTE compatible SDI
optical fiber module. The optical input automatically detects between
SD/HD/6G/12G-SDI. The optical output provides the converted video with
embedded audio.
11 L – Analog or AES/EBU
Balanced left channel analog audio, or digital AES/EBU audio input XLR connector.
12 R – Analog, AES/EBU or Timecode
Balanced right channel analog audio, or digital AES/EBU audio input XLR connector.
Can also be configured for timecode input.
Switches
Teranex Mini Audio to Optical 12G's switches provide the following settings:
Switch 8, 7 – Input Audio Selection Bit 1, 0
Switches 8 and 7 are represented as bits 1 and 0, respectively. This simply means that by setting
various on/off combinations for switches 8 and 7 you can select from four input audio options.
Switch 6, 5, 4 – Embed Audio Bit 2, 1, 0
Switches 6, 5, and 4 are represented as bits 2, 1, and 0, respectively. This simply means that by
setting various on/off combinations for switches 6, 5, and 4 you can select which channels of
your SDI or optical signal you wish to embed audio into.
If you are embedding analog audio, there are eight combinations, allowing you to embed audio
into the channel pairs from 1-2 through to 15-16.
If you are embedding AES/EBU audio, there are four combinations. You can select between
embedding audio into channels 1 to 4, 5 – 8, 9 – 12, or 13 – 16.
Switch 3 – Sample Rate Conversion, No Sample Rate Conversion
Set switch 3 to OFF to enable sample rate conversion, or ON to disable sample rate conversion.
This switch should almost always be set to OFF to ensure audio is embedded at the correct
sample rate for television.
When switch 3 is set to OFF this setting converts the sample rate of your analog or AES/EBU
audio and embeds audio into the optical output at a sample rate of 48 kHz.
Switch 2 – Ch 2 or AES/EBU 3+4 Embed / Bypass
Once you have selected your audio channels, use switches 2 and 1 to select which channels to
embed or disable. The disable setting lets you avoid overwriting audio channels you wish to
keep in the audio signal.
Set switch 2 to ON to bypass channel 2, or AES/EBU channels 3 and 4. Set switch 1 to ON to
bypass channel 1, or AES/EBU channels 1 and 2.
