Mic preamp effect types
(7) ZNR (ZOOM Noise
Reduction)
OFF, 1 – 16
Adjusts the sensitivity of the noise reduction circuit
developed by ZOOM.
SVT Simulation of Ampeg SVT sound.
BASSMAN Simulation of Fender Bassman 100 sound.
HARTKE Simulation of Hartke HA3500 sound.
SuperBass Simulation of Marshall Super Bass sound.
SANSAMP Simulation of Sansamp Bass Driver DI sound.
TUBE PRE ZOOM original tube preamplifier sound.
The above 6 effect types have the same parameters.
(1) CABINET
0 –2
(2) GAIN
0 – 100
Adjusts the intensity of the speaker cabinet sound. Adjusts the preamp gain (distortion depth).
(3) BASS
-12 – 12
(4) MIDDLE
-12 – 12
Adjusts boost/cut in the low range. Adjusts boost/cut in the middle range.
(5) TREBLE
-12 – 12
(6) BALANCE
0 – 100
Adjusts boost/cut in the high range.
Sets the mixing balance between the signal before
input and after passing the module. Higher values
result in a higher ratio of post-module signal.
(7) LEVEL
1 – 100
(8) ZNR (ZOOM Noise
Reduction)
OFF, 1 – 16
Adjusts the level of the signal after passing the
PREAMP module.
Adjusts the sensitivity of the noise reduction circuit
developed by ZOOM.
VO MICPRE Preamp with characteristics optimized for vocals.
AG MICPRE Preamp with characteristics optimized for recording an acoustic guitar.
FLAT MPRE Preamp with flat characteristics.
The above 3 effect types have the same parameters.
(1) COMP OFF, 1 – 10 (2) DE-ESSER
OFF, 1 – 10
Adjusts the parameter which keeps the level within a
certain range by attenuating high-level signals and
boosting low-level signals.
Adjusts the degree by which sibilants are attenuated.
(3) LOW CUT OFF, 1 – 10 (4) BASS
-12 – 12
Adjusts the frequency of a filter designed to attenuate
low-frequency noise that is easily picked up my a mic.
Adjusts boost/cut in the low range.
(5) MIDDLE -12 – 12 (6) TREBLE
-12 – 12
Adjusts boost/cut in the middle range. Adjusts boost/cut in the high range.
