Figure 23: Gyda configuration view of the audio cross point matrix
All outputs have a common fallback option that can be set in Gyda. The priorities can be
selected between matrix (being the choice in the cross point matrix), sine, mute or delete.
Mute is merely silence, while Delete deletes any audio content and set the audio control
package to channel delete for its respective channels.
5.15 Audio generator
The stereo audio generator is available in the audio cross point matrix as a source. It is a
high purity 1 kHz sine wave with a 250ms interruption on the left channel every 3 seconds.
The audio level may be set to one of two standards. The two levels are -18 dBFS and -20
dBFS. These two levels correspond to EBU R68 and SMPTE RP 155.
5.16 Audio processing block
The output of each stereo signal from the audio cross point matrix may be processed in the
audio processing block. This is controlled with the Gyda controller. The processing includes
channel L/R manipulation and audio gain.
