Non default option 2B
The buffered out (jack 3) becomes a volume pedal insert with the jack
functioning as a “trs” type with the tip being a post pip level control send
to the volume pedal and the ring being the return to the pip. The lower
impedance volume pedals (typically 25k ohms) are recommended for
this application. You can use a pre made cable such as a hosa 3SR-03Q
to seperate the send and return, or some expression pedals will work as
a volume pedal, these have a sngle send/return plug.#112 jumper 2&3 /
#128 jumper 2&3 / on #129 jumper 2&3.
Non default option 3B
This will turn the buffered out (jack 3) into a summing input jack. It will
then function the same as the summing in (jack 2). This will sum after
the main input stage with whatever is plugged into the instrument input
(jack 8),and the summing in (jack 2). See non default option 2A for more
information.#112 jumper 1&3 / #128 jumper 4&3 / on #129 jumper
1&3.
Jumpers #190 and #191, determine the lo z setting input im-
pedance and the level control impedance.
The default impedance for the lo z setting and the level control is
10k ohms. Jumper #190 & #191 jumper 2&3
Non default option 1C
This sets the level control and the lo z input impedance to 5k ohms useful
in the volume pedal default option 2B setting and the non default option 1B
setting because you can use a longer cable if the send to the volume pedal
or the buffered out is a maximum of 5k ohms rather than the maximum
10k ohms( at 10k ohms the hi end frequency response could be affected).
Jumper #190 & #191 jumper 1&3.
Jumpers #71 and #72 determine the functionality of the main output
xlr (jack 7)
The default function for this jack is as follows:
The xlr balanced main output (jack 7) is fed pre the re-amp in (jack 6)

Main instrument in. This front panel jack is where you plug your instrument in or, in a rack
mounted application, you can plug your instrument into the rear panel instrument thru jack.
Instrument thru. This can be used as a rear main instrument input jack
OR
a thru jack (mult) out
to feed your instrument amp(the default setting)
OR
as a rear main instrument input jack that is
interrupted when you plug in the front (especially useful in a rack mounted situation )
OR
as an
extra summing amp input.
Summing amp in. Use this input to sum with the main input devices such as bass pedals, key-
boards etc. The PIP can be used as a mini hi fidelity mixer!
Buffered output. Internal user configurable jumpers can set this output to be fed from either
pre or post the level pot (pre is the default setting)
OR
this output can be configured as a trs
volume (tip send /ring return)"expression" pedal jack pre or post level pot
OR
this output can
be an extra summing amp input.
Balanced only expansion out. This line level output can be used as a balanced insert send pre
the instrument level hi Z transformer out (re-amplifier) and, if installed, pre the line level or mic
level lo Z output transformer. This allows you to insert a piece of pro gear before the PIPs main
xlr output. This insert will also allow you to properly interface pro gear before your guitar amp
and still achieve the proper tone of a pickup plugged directly into the amp.
Re-amplifier input and instrument level hi Z main output (re-amp out).The re-amplifier section
can be used completely independent of the rest of the Multi Z PIP. Use it to re-amp guitars or
to use vintage pedals on a send, Use it in conjunction with The DI section (for gain make up) to
use vintage pedals on an insert. Re-amplifier level is set by a 10 turn trim pot located on the
rear of the PIP. The re-amplifier out is also the main guitar level/impedance, transformer
isolated, ground liftable output for the Multi Z Professional Instrument Preamp.
Balanced main XLR output. This ouput is available with three options. Line level transformer-
less out, Line level transformer isolated out, or mic level/impedance transformer isolated out.
Internal user configurable jumpers can set this output to be fed pre or post the re-amplifier
input jack or when using the mic transformer, pre or post the level pot.
