Audio Configuration Menu
Mitto has three possible audio inputs.
1. The first type of audio input is analog. There is a 1/8 inch mini-jack in the back of Mitto that will
accept two channels of stereo analog audio. When the Analog input is selected, the left channel is
assigned to Input 1 and the right channel is assigned to Input 2. Mixer Inputs 3 and 4 are not used.
2. The second type of audio input is AES. If you choose AES, the 1/8 inch mini-jack in the back of
Mitto can accept two AES bitstreams (four channels), one on the left pin of the connector and one
on the right pin. When AES (or S/PDIF) is selected, the bit stream connected to the left input will
appear on Mixer Inputs 1 and 2, and the right bit stream will appear on Mixer Inputs 3 and 4.
3. The third type of audio input is through HDMI video coming in through the DVI port. The HDMI
standard can support eight channels of digital audio. HDMI audio will appear on Mixer Inputs 1
and 2. If you select DVI, an HDMI source fed to the DVI connector will provide the audio into Mitto.
Mitto has two audio output capabilities.
1. The four channels of audio from the audio mixer can be embedded in the SD SDI or HD SDI output.
Embedded audio travels with the digital video through cables, distribution amps, and routers
without the need for any additional wiring. The SDI standard allows 16 channels of embedded
audio, which is organized into four groups of four channels each. The four channel output from
Mitto fits into a single group. You can assign the audio to a specific group using the Embedding
control in the Audio Config Menu. This control also allows you to turn embedding off.
2. Mitto can also output two channels of digital audio as an AES bit stream (just like the input
capability). This AES output shares a connector with the Composite Video output. The Cpst/AES
Out control in the Output Menu configures this connector to output either Composite video,
AES channels 1 and 2, or AES channels 3 and 4.
• Audio Input – Select from Analog, AES or DVI. See section directly above for more specific
details on Analog, AES and DVI.
Analog – Select Analog if you are feeding Mitto analog audio. Mitto will accept two
channels of stereo analog audio via the 1/8 inch mini-jack in the rear of the unit. The analog
audio can be embedded onto the SD SDI or HD SDI outputs.
AES – Select AES if you are feeding Mitto digital audio. Mitto can accept two AES bitstreams
(four channels) via the 1/8 inch mini-jack in the rear of the unit. The digital audio can be
embedded onto the SD SDI or HD SDI outputs.
DVI – Select DVI if you are using audio that is present on the HDMI video coming in through
the DVI port.
Note: You can assign the audio to a specific group using the Embedding control.
This control also allows you to turn embedding off.
