Configuring and using the Torpedo VM-202
8.2
Center
• Determine the distance between the axis of the loudspeaker
and the microphone (placed at right angle). The in-axis po-
sition (0%) allows the maximum amount of treble, which are
highly directional. Moving the microphone away from the axis
decreases the treble to the benefit of the bass response. At
maximum position (100%), the microphone is placed at the
edge of the speaker when Distance is 0%, and 1 meter (3 feet)
away from the axis when Distance is 100%.
8.3
Position
• In standard sound capture, the microphone is usually placed in
front of the cabinet. However, placing the microphone behind
the cabinet can be quite interesting. The sound is usually softer
and darker. This is particularly obvious with closed cabinet, less
with open ones.
8.4
Variphi
• The Variphi parameter is a one-of-a-kind control, exclusively
found in the Torpedo technology. It allows you to modify the fre-
quency content of the signal, using the properties of the sum of
two signals with different phase. You are emulating a situation
where two microphones are used, and the Variphi parameter
controls the distance (hence the phase relationship) between
the two microphones. To easily hear this effect, we recommend
to start with a crunch/saturated sound on your amplifier and
change the Variphi parameter. You will hear a periodic change
in the signal with frequency modifications. Using Variphi, you will
fine tune the frequency content of the signal, whether you are
looking for a "mid-scooped" or a "full" sound. Note that this pa-
rameter is always working. The O position is not a 0 value, but
a first shift phase value between the first and the second virtual
microphone
