A98SPM ASSEMBLY
FIGURE 10
4. Mount the swivel adapter on the microphone stand.
5. Attach the microphone cable to the 98-A98SPM.
6. Mount the Microphone-Polar Modifier combination in the
adapter as in steps 3 through 5 of the Installation section.
7. To remove the microphone assembly from the swivel adapter
without disturbing the adapter and cable, reach into the open
slot of the adapter and press the cable-lock button while disen-
gaging the microphone.
NOTE: The Microphone-Polar Modifier assembly can be used
with or without its supplied acoustic foam windscreen. When
mounted on the SM98A-A98SPM, the windscreen not only pro-
vides excellent wind and pop protection, but helps protect the
A98SPM internal element from contamination.
DISASSEMBLING THE PREAMPLIFIER (SM98A)
1. At the XLR connector end of the preamplifier, turn the slotted
head setscrew fully inward (counterclockwise), and use a long-
nose pliers to carefully withdraw the connector from the case.
2. Unsolder the three lead wires securing the XLR connector to
the XLR board.
3. Remove all four Phillips-head screws from the preamplifier
case (three on the switch side, one on the back).
4. Grasp the end cap and withdraw the cap assembly, pc board
assembly, and connecting wires and jacks from the case.
REASSEMBLING THE PREAMPLIFIER (SM98A)
1. Make sure the pc board is seated in the slot of the end cap and
that no wires are pinched.
2. Insert the end cap-board assembly into the case, XLR connect-
ing wires first. Again, take care not to pinch the wires connect-
ing the board to the end cap.
3. Rotate the assembly inside the case until the four holes for Phil-
lips screws line up with the holes in the case.
4. Replace the four Phillips screws.
5. Resolder the three lead wires to the back of the XLR board as
shown in Figure 11.

6. Replace the XLR board-connector assembly in the case, lining
up the key in the connector with the slot in the case. Take care
not to engage the butterfly-shaped ground contact in the key
slot as it will prevent seating the connector properly.
7. Insert the connector fully in the case until the slotted setscrew
can be seen in the case hole; tighten the setscrew firmly by
turning it clockwise.
