Cable Assembly Procedure
Cable Assembly Procedure
The stereo preamplifier relies on the power supply contained in the audio amplifiers of the
WhitakerAudio line to function. Power from the amplifier is coupled to the preamp through a
connecting cable. This document describes the procedures for assembling the necessary cable.
The pinout for the power connector is given in Table 1.
1 Procedure
Expandable flexible sleeving is used to bundle the wires of the cable assembly. To properly
perform the following steps, it will be necessary to have a heat gun on hand. (A common hair
dryer may be sufficient.) In addition, the preferred method of cutting the tubing is to use a so-
called “heat knife.” If such a tool is unavailable, scissors may be used.
Examine the connector body. The pin numbers are stamped on both sides of the device. Be
certain to place each pin in the correct position.
The following procedure is recommended for assembling the connecting cable.
1.1 Step-by-Step Instructions
The standard length for this cable is 3 ft. Users requiring a longer (or shorter) cable should adjust
the following steps accordingly.
– Prepare two 3-ft pieces of #16 black stranded wire. Attach male connectors on one end
and female connectors on the other end.
