INSTALLATION - RK100PK (BLACK), RK100PKW (WHITE)
The RK100PK and RK100PKW preamp comes assembled for

use with microphones using a miniature 4-pin connector. To wire a

microphone cable directly to the preamp, follow these instructions:

Turn screw (A) counter-clockwise until it recedes below

the case.
Remove the cap (C) by removing the set screw (B) with

the provided hex wrench (.05 in.).

Insert the rubber flex relief (G) into the cap (C) and feed

through the microphone cabling.

Note: You will need to reuse the rubber flex relief from your old

preamp. If the rubber flex relief is unavailable, please contact the

Shure Service Department.

Push the circuit board back into the case, making sure

that the set screw (A) is lined up with the screw hole in

the side of the case (if the circuit board does not go in

all the way, twist it slightly until the screw and hole are

aligned). Raise the set screw (A) by turning clockwise

so that the preamplifier is held securely in place. Screw

on the cap (C). Do not use the set screw with the cap.
