Gain Compensation

When your NSB-series stage box is connected to multiple mixers, you have the option to designate only

one to have control over the preamps. In this way, only one engineer is in charge of gain staging on

stage. Once the preamp level is set by the master mixer, every other mixer on the network has the option

of listening to the same stream or the gain compensated stream.

Routing the AVB stream that isn't gain compensated means that you will have no control over the level of

the streams feeding the inputs ofyour mixer. While this may be fine in some situations, this could create

gain staging issues in others.

Using the Gain Compensated (GC) stream allows you to retain independent gain control on each mixer

without potentially harming the Front-of-House mix. NSB stage boxes have an onboard DSP that adjusts

the level of the gain compensated streams relative to gain set on the master mixer. In this way, every

mixer on the network has a working gain range of +/- 20 dB, even if they are not the set as the master

preamp controller for the stage box.

Once Gain Compensation is engaged, the Master mixer can adjust the gain of each NSB preamp +/- 15

dB before the change will be heard locally on any mixer receiving the Gain Compensated stream.

stage box, select the non-Gain Compensated

streams for your inputs.

After you route the NSB inputs to your console

mixer, select Network for the source on the cor-

responding channels.
