OVERVIEW & INSTRUCTIONS
2
» HP Button
Depress this button to engage a 12dB/Oct highpass fi lter at 80Hz to
remove undesired low frequency content, e.g. rumble or pop noises,
from your signals.
» Phase invert
Use this button to fl ip the polarity of the processor‘s output signal.
» In Button
Engages or bypasses the processing altogether.
» Gain
Controls the virtual preamp gain b18 and +72dB. While the
knob on the original unit is stepped we went for continuous operation
for better adjustability of the added harmonics. You can drag the
gain knob holding your right instead of your left mouse button and
the trim knob will follow in the opposite direction. This way you can
dial in as much THD as desired without aff ecting the volume of your
signals too much.
» Trim
Use this knob to adjust the output gain of the processor in the range
between -30 and +30dB to compensate for any level changes applied
by the preamp section. The trim gain stage is completely linear and
does not add any additional harmonics. You can also drag the trim
knob holding your right instead of your left mouse button and the
gain knob will follow in the opposite direction. This way you can
dial in as much THD as desired without aff ecting the volume of your
signals too much.
» HF Gain
The HF gain knob adjusts the high shelving gain applied to your signal
aft er the preamp stage. The range is roughly -15 t15dB.
» Signal LED
The signal LED monitors the VPRE-73‘s output level in diff erent levels
of green. It will light up in red once your signal hits the 0dBFS mark.
