The SX-22 balanced analog I/O levels are specified in dBu, where 0 dBu is 0.775 Vrms or
2.19Vpp for a sinewave. If an I/O is connected as unbalanced then the level is 1/2 the balanced
I/O. The adjustable level is referred to as Trim. The following Trim settings are available on the
SX-22.

The input and output trims may be adjusted separately, but both input or both output channels
must have the same setting.
