Setting Input Gain
The
Percussion Interface
boosts low level signals in order to generate gates and envelopes at
modular level. There are two controls for adjusting gain: the
L|M|H
switch sets the gain range, and the
Sensitivity
pot adjusts within that range.
Setting the Gain Without a PI Expander
If you are using the
Percussion Interface
alone
(without the
PI Expander
) the gain range can be
set using a jumper on the back of the
Percussion
Interface
. Note that if the jumper is missing
completely, the default setting will be MEDIUM
GAIN.

Range
Use Cases
L (Low Gain)
0–2x
gain
Best for modular level and some professional line level
signals
M (Medium Gain)
0–20x
gain
Best for instrument, line, and some low impedance mic
signals
H (High Gain)
0–500x
gain
Best for high impedance mics, piezo discs (contact
mics), and other very low signals
