Connections

Labels on the module show the position and type of
expected connections. SDI input can connect via BNC
connectors or a choice of the following SFPs:

Operation

The IDC 1411 module supports automated plug-and-play functionality. In
case the default parameters are not suitable for your intended purpose it
is possible to change them via the yellow interface of our control software
LynxCentraal or yelloGUI. A USB Connection to the module is necessary for this.

Settings

With a USB connection to a LynxCentraal or yelloGUI workstation established
you get access to the device settings.
The IDC1411 processes one stereo audio channel which can be freely cong­ured to be sourced either from one of the SDI Inputs embedded stereo chan­nels or from AES Input.
The AES Output will always contain the processed stereo audio channel.
Additionally one of the SDI Outputs embedded audio channels can be over­written by the processed stereo audio channel.
Audio processing is split into three function blocks:

• Audionamix® IDC

• Equalizer

• Compressor

Processing Delay

The timing of the SDI and AES Output will be locked to the SDI Input. Additional
delay introduced by the audio processing will be compensated depending on
the video refresh-rate resulting in the following input to output delay:

Audionamix® Instant Dialogue Cleaner

This audio filter is based on the plugin developed by Audionamix® to provide a
hardware based solution that works independently of software in realtime with
minimal delay.

Powered by a deep neural network that separates and preserves speech in real
time you are able apply a gain (-66.3 – +18dB) to speech and background sepa­rately. This allows you to remove background interference without compromis­ing integrity of the dialogue.
The Strength parameter allows you to slightly modify what is identified as
speech and respectively as noise. Increasing the strength will cause the filter to
be more “agressive”, i.e. it will identify more content as noise.

Dialogue Cleaner can be enabled separately from the other functions like the
Equalizers or Compressor.

If your audio signal needs to be increased or reduced after this process, a master
gain is available as IDC Output Gain, which can be enabled separately.

Equalizer Settings

Two fully parametric peak/notch equalizers are provided which are applied in
series.
Both Equalizers provide parameters for the center frequency (20Hz – 20kHz),
gain (-66.3 – +18dB) and Q (0.3 – 50) which controls the bandwidth.

Equalizers can be enabled separately from the other functions like the Dialogue
Cleaner or the Compressor.

If your audio signal needs to be increased or reduced after this process, a mas­ter gain is available as EQ Output Gain, which can be enabled separately.

Compressor Settings

A hard-knee, peak-sensing, stereo-linked audio compressor is provided with
parameters for Threshold (-60 – 0dBFS), Ratio (1:1 – 30:1), Attack (0 - 200ms)
and Release (5 – 5000ms).

Compressor can be enabled separately from the other functions like the
Dialogue Cleaner or Equalizers.

If your audio signal needs to be increased or reduced after this process, a
master gain is available as Comp Output Gain, which can be enabled sepa­rately.
