PREAMPLIFIER INSTALLATION
Installing the In-Line Preamplifier (FIGURE 2)
Use the two supplied mounting clamps to hold the pream-
plifier in place on a wall or ceiling. Set the length of the cable
by cutting it appropriately and using the screw terminal con-
nections inside the preamplifier. The terminals are marked
B (black), R (red), and S (shield).
Plate-Mount Preamplifier Input Connections
1. Detach the preamplifier housing by removing the two
Phillips head screws from the back of the housing.
2. Remove the material from the hole in the center of the
cover plate or the center of the preamplifier housing.
3. Cut the cable to the desired hanging length, allowing for
a 76 mm to 101 mm (3 to 4 in.) service loop.
4. Clamp the strain relief around the cable and insert the
strain relief into the hole.
5. Connect the cable leads to the terminal block (B = Black,
R = Red, S = Shield).
Plate–Mount Preamplifier Output Cable Connections
1. Using professional-quality, two-conductor, shielded micro-
phone cable, thread the output cable from the outside of
the preamplifier through the hole with the black bushing.
2. Connect cable to pins as follows: Pin 2 = +, Pin 3 = –, Shield = S.
3. Reattach the preamplifier housing.
MICROPHONE INSTALLATION (FIGURE 3)
The microphone is most stable when the gooseneck is bent
into a "lazy S" shape as shown in Figure 3. Use the supplied
hanging clip and heavy thread or monofilament fishing line to
suspend the microphone at a specific location.
INSTALLING THE FOAM WINDSCREEN (FIGURE 4)
1. Press the foam windscreen onto the microphone until it
snaps into the groove located behind the cartridge.
2. To remove the windscreen, spread the gap in its mount-
ing ring with a screwdriver or thumbnail and pull the
windscreen off.
