The Decimator II Noise Reduction pedal is the latest
generation in noise reduction technology. The
Decimator features improved Linear Time Vector
Processing that offers the smoothest, ripple free
approach in tracking the envelope of the input signal.
The LTVP will instantly respond to short staccato notes
and at the same time provide ripple free control of long
sustained notes while downward expanding. The
Decimator pedal is easy to use and simple to operate.
The threshold control on the Decimator II should be
adjusted by listening to the noise floor while no
instrument signal is present. The threshold control
should be turned clockwise until the noise floor
becomes inaudible. It may be necessary to readjust the
threshold with the guitar volume all the way on in order
to accommodate the additional noise the guitar may
induce. Adjusting the threshold too far clockwise may
cause the downward expander to attenuate the output
level too quickly and not allow the signal to decay
naturally.
BATTERY / ADAPTER
To install the battery, loosen the thumbscrew shown
above and raise the switch cover to allow access to the
battery compartment. Insert a 9v battery to the
connector and place the battery into its compartment
and close by holding the switch cover down and
tightening the thumbscrew.
To use the Decimator II with an external power adapter,
select an adapter with at least 100 milliamps capability
at 9 volts DC. Make sure the adapter is polarized “TIP
NEGATIVE”.
CONNECTIONS
For best performance place all gain pedals in
front of the Decimator II. You can put Delay
and Reverb effects pedals after the Decimator
II to avoid cutting off reverb and delay tails.
NOTE: When connecting the Decimator into
the effects loop of your amplifier connect the
send to the Decimator II Input and return to
Decimator II Output.

The guitar is connected to the input of the first pedal and Guitar Out feeds the input of a guitar head or
input of a pedal chain. The second Decimator II is connected in the effects loop of the Head with Send
connected to Guitar IN and Return connected to Guitar OUT. Adjust the Threshold by setting the
Threshold of the first pedal to remove the noise of the Guitar first and then adjust the second pedal
Threshold to remove the HEAD gain noise.
The first Decimator pedal in the chain is a Decimator II G String and the G String is required to provide
a separate Guitar IN and Guitar OUT to feed the front end of a Stereo system. The Guitar is connected
directly to the Guitar IN of the Decimator II G String. The Guitar OUT requires a Y Cable to feed the
input of both channels in Stereo. In this example the Guitar OUT is connected to a Stereo Pair of
pedals. The outputs of the stereo pedal chains are connected to the Decimator IN on both the G-String
II and standard Decimator II pedals. The Decimator OUT of both the G String II and Decimator II pedals
are connected to the Stereo Input of an ISP Technologies STEALTH power amplifier. Connect an RTS
1/8 inch cable from the LINK OUT of the first Decimator II G-String pedal to the LINK IN of the second
Decimator II pedal. Adjust the threshold control of both pedals for the proper noise reduction and no
further adjustment should be required.
This diagram on the left
shows how to LINK two
Decimator II pedals allowing
the second pedal to track the
direct instrument input. This
will allow the second pedals’
internal level detector to track
the guitar directly, providing
tracking performance similar
to the professional rack mount
Decimator ProRack G.
Connect an RTS 1/8 inch
cable from the LINK OUT of
the first pedal to the LINK IN
of the second pedal.
This diagram shows just one
example of how to connect a
Decimator II G String pedal
with a standard Decimator II
pedal for true Stereo
applications. A true stereo
Decimator system can be
realized by linking a Decimator
II G String and a standard
Decimator II. The above
Diagram shows how to connect
two pedal chains in Stereo.
There are countless True
Stereo Applications: this
Diagram simply shows an
illustration of how to connect
the two Decimator II pedals for
true stereo use.
