Question: What does the compressor work in the GO XLR?

Compressor with expanded controls

Compressors even out sounds by reducing the loud portions and increasing
the quiet parts, i.e., they “squish” or compress the sound into a more narrow
dynamic range. Compression is extremely important to voice professionals,
such as radio DJs and voiceover artists, so your livestream broadcast will sound
more professional.
The expanded Compressor controls include these functions:
•     Threshold—This parameter controls the signal level at which the
compressor begins to work. If you want to manually control the Threshold,
speak into the mic while slowly lowering the Threshold slider from the top
0 dB setting, until you find an acceptable level. A high Threshold setting
will only affect the highest signal peaks, while a lower ratio will apply
compression to a greater proportion of the signal.
•     Ratio—The Ratio controls the intensity of the compression effect. Higher
ratios will produce a more intense effect, while lower ratios will be gentler.
•     Attack—The Attack parameter controls how quickly the compressor reacts
to signals that go over the Threshold setting.
•     Release—This parameter determines how quickly the compressor lets go
of the signal.
•     Make-Up Gain—This control is important because by reducing the loudest
parts of the signal, compression makes the overall signal seem more quiet,
even though you haven’t changed the volume. By increasing the gain on the
way out of the compressor, you can restore the original perceived volume.
