( ) Install J2 (MIC IN) - 8 Pin Male Mic Connector on back of case
( ) Install J3 (MIC OUT) - 5 Pin DIN connector on the back of the
case. (This will require 2 screws, 2 lock washers and 2 nuts)

( ) Pre-wire Rotary switch S4 as shown below and install on rear
of case. The wires going to J2, J3 and J4 should be cut to 3.5
inches. They can be trimmed when the switch is installed in
the case and wired. Pre-wiring the switch, with insulated wire,
makes wiring it significantly easier. (2 center posts on S4 wired later)
( ) Install the pre-wired switch S4 - Mic Select. Pay attention to
the alignment of the switch (per the figure 1). Install the round
