Downmix Audio Input
In sound recording and reproduction, downmixing is the process by which multiple recorded paths are combined into one or more
paths.
In multi-track recording, multiple sound sources are recorded from separate microphones to individualized audio paths.
Downmixing is the process of combining those audio paths to produce one or two paths that include all content.
Dante Audio Switching Board Downmix Input
Dante Audio Switching Output Boards provide the ability to downmix the audio signal from one input (must be assigned as the
downmix input) to stereo audio.
The downmixed input is fed from a single selectable embedded audio input from any Enova DGX Input Board. While the sample rate
can be any valid rate, the data will be sample rate converted to 48 kHz. Downmixed audio from a single input can be switched to any
or all embedded or Dante-connected audio outputs.
Input Gain -24 dB to +24 dB
• Allows source signals of varying amplitudes to be equalized
• Inputs are set to unity gain at the factory
TIP: Make input gain adjustments before fine tuning the outputs.
EQ Gain -12 dB to +12 dB
Compression (Enable/Disable) Audio inputs (when enabled) can be independently configured for the following
settings:
• Attack from 1 to 2000 milliseconds
• Release from 10 to 5000 milliseconds
• Threshold of -60 dB to +0 dB
• Ratio 1 to 20
Delay 0 to 200 milliseconds (each audio signal independently)
10-Band Parametric Equalizer Selectable center frequency for each band independently
• Used to boost or cut the frequencies for each output
• Each equalization band spans one octave and is identified by its center
frequency
• Bands are set for a flat response (0 dB) at the factory
Preset Filter Types Available preset filter types (apply to each band independently):
• Bell
• Bass shelf
• Treble shelf
• Low pass
• High pass
• Band pass
• Band stop
Band Gain -12 dB to +12 dB
