Configuring and using the Torpedo VM-202

Output volume control and headphone output
Depending on the output routing configuration (refer part 3. 1),
you have different configurations (Volume or Pan) assigned to
the encoders.
As the VM-202 is a digital audio processor, it is absolutely critical
to avoid any saturation of the input signal, at the risk of consid-
erably reducing the audio quality. The output volume or PAN is
digital data, like all the parameters in the VM-202, and is saved
with the preset. You will have to adjust the output volume for
each preset. Please note that output volume depends on the
speaker cabinet and microphone used for the simulation, as
well as microphone positioning. You may need to readjust the
output volume when modifying these parameters.
The output volume adjustment must be done with input signal present at the input selected (analog or
digital). The "OUT" label a the upper right corner of the main screen indicates the current output volume
value. The output bargraph gives you a visual indication of the output signal amplitude.
For optimum quality, we advise to keep the peak levels of the output signal at a maximum of -6dB on
the bargraph.
If you have to apply a high output volume gain, your input signal is probably too low. A too high output
volume will reduce the signal-to-noise ratio and degrades overall performances of the VM-202. If you
notice a drop in the sound volume and a "Gain Reduction" display on the screen while you play, the "Safe
Gain Adjustment" is certainly activated. Report to section 4 for more information.
The "PHONES" potentiometer controls the headphone volume on the 6,35mm (standard 1/4") jack
headphone output. This control is placed after the output volume control. A too low output volume
setting, offset by a high headphone volume setting, will reduce the signal-to-noise ratio and degrades
overall performance of the VM-202.
The power delivered by the headphone output is high enough to remain
efficient even when using high impedance headphone. Therefore, it is
possible to have very high audio levels with the VM-202 output.
We strongly
advise against the use of headphones with high audio levels. The improper
use of headphones can lead to irreversible damage to your hearing.
