The Scaler DB module scales multichannel signals by a single gain value specified in dB, ( gainDB). gainDB is automatically converted to a linear value: gain. Internally gain is the gain actually applied to the signal. The module has 1 input pin and 1 output pin of the same dimension as the input.

Note that the The module is not smoothly varying, and the gain value is applied to both the real and imaginary parts. If you update the gain value, you may introduce an audible click. For clickless operation, use the ScalerDBSmoothedFract32 module instead, which does not work with complex data.
