Analog Signal Gain
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
input signal. As a result, 48 dB of gain on a SoundStructure input is equivalent
to a gain of 15 dB on a Vortex mic/line input that is in mic mode because of the
additional 33 dB of gain on the Vortex when in mic mode.
