on those signal paths. More frequently used controls such as input gain and
input fader are always available and are visible even when the control is
collapsed.
SoundStructure devices have a continuous analog input gain stage that oper-
ates on the analog input signal and has a range of -20 dB to +64 dB with 0.5 dB
gain increments. Values are rounded to the nearest 0.5 dB. This continuous
gain range is different from the gain Vortex products uses because the Vortex
microphone inputs have a mic/line switch that adds 33 dB of gain to a Vortex
