An application for channel bias is when there are wireless presenter microphones that are also reinforced

into the local room in addition to other microphones that are not reinforced into the room. The wireless

microphones can be biased to become active even if the presenter gets close to another microphone – this

keeps the reinforcement heard in the local room and not change the tonality as could happen if another

microphone became active.

Processing Delay

The delay processing allows the designer to add up to 1000 milliseconds of delay on the input channels.

While the delay is set in milliseconds in the user interface, it can be manually set through the command

console in samples where each sample represents 1/48 of a millisecond.

The input delay may be enabled and disabled and may be adjusted from 0 to 1000 msec.

The fader control enables the user to add gain or attenuate the input signal from +20 dB to -100 dB in 0.1

dB increments. This gain or attenuation is applied in the digital domain. The fader control is shown in the

following figure.

Fader Control in SoundStructure Studio

A maximum and minimum gain range can be specified for the input faders to make it possible to limit user

gain control by moving the triangles associated the gain slider. To set the maximum fader gain, adjust the

main slider to the desired maximum gain and then move the upper triangle to that level.
