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
