PREAMPLIFIER INSTALLATION
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
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.
CEILING TILE INSTALLATION (Figure 4)
Remove: Plate-Mount Preamp Connection
1. Drill a 1/2" hole into the ceiling tile.
CAUTION: To avoid damaging the tile, use a 1/2" augur bit
and drill by hand or very slowly with a variable-speed drill.
2. Unplug the mini 4-pin connector from the preamp and feed the
cable through the hole.
3. Place the rubber grommet, tip down, over the cable and posi-
tion it to suspend the microphone at the appropriate height.
4. Fit the grommet securely into the hole. For 5/8" ceiling tile, use
the supplied washer.
5. Reconnect the Preamp.
INSTALLING THE IN-LINE PREAMPLIFIER (Figure 4)
Use the two supplied mounting clamps to hold the preamplifier in
place on a wall or ceiling.
ADJUSTING PREAMP GAIN: MX202B AND MX202W ONLY
(Figure 5)
MX202B and MX202W microphones include an adjustable gain
preamplifier, allowing the user to specify a 12 dB or 0 dB gain
setting. The preamp ships at 12 dB setting. To reduce the signal
gain at the MX202B and M202W preamplifier by 12dB, replace the
gain resistors to the 0dB setting (Table 5A).
RF FILTERING
MX200 Series must be used with RK100PK or RK202PK
preamplifier, in order to optimize RF immunity.
