1. GAIN (stepped, 12-position switch): clockwise
rotation yields an increase in input signal amplitude,
counterclockwise rotation yields a decrease in input
signal amplitude
2. 48V: engage to turn phantom power on, disengage
to turn phantom power off
3. PHASE: engage to adjust input signal polarity by
180°, disengage to leave input signal polarity
unchanged
4. OUT LEVEL: clockwise rotation yields less
attenuation, counterclockwise rotation yields more
attenuation (for beginners, it’s best to leave the
output level fully clockwise and increase Gain as
needed so as not to saturate the input transformer)
5. Hi-Z: engage to select faceplate TS jack as input
source, disengage to select XLR input jack on 500
series rack as input source (GAIN does not adjust
signal level, however, OUT LEVEL does attenuate
the signal)
