the default and custom configuration

options for the multi z 

professional instrument preamp

The following describes where the blue jumpers inside the PIP must be set 

in order for it to function, either in its default mode or other custom modes 

to suit your needs.  To gain access to the PIP jumpers you need  to remove 

the rear panel and the top cover. In order to do this you need a 1/16” Allen 

hex tool to remove the two rear panel cap screws and the 2 xlr cap screws. 

The rear panel and the plastic frame should come right off. A service loop 

is provided to keep the power connector attached.
Jumpers #30,#31,#35 and #75 all determine the functionality of the 

instrument input (jack 8) and Instrument thru (jack 1). Please Note: 

These jumpers and the default has changed on Revision 2 

 

 

The default function for these jacks is as follows: 

Whatever is plugged into the instrument input (jack 8) will appear at the 

Instrument thru (jack 1). Useful when you would like to use the PIP as a 

traditional DI with the instrument “Yed” feeding the instrument input (jack 

8) and instrument amp at the same time. With nothing plugged in the instru-

ment input (jack 8), the input to the PIP is shorted and the outputs will be 

quiet, useful when you are leaving the PIP connected to a console or amp.  

#30 and #31 jumper 2& 3 / on #35 jumper removed on #35X jumper

page).
Non default option 1A 

Whatever is plugged into the Instrument thru (jack 1) is interrupted by what 

is plugged into the instrument input (jack 8). With nothing plugged in the 

Instrument thru (jack 1), or the instrument input (jack 8), the input to the 

PIP is shorted and the outputs will be quiet, useful when you are leaving 

the PIP connected to a console or amp.  #30 and #31 jumper 1 & 3 / on
