3.Using the supplied mounting screws and wash- ers, screw the swivel mount to the lectern top. Tighten the mounting screws securely. Do not overtighten. Some slight wobbling of the base is normal when the microphone is moved.

4.For unlimited microphone rotation, remove the set screw in the base of the microphone. Caution:

If the boom arm is rotated fully around, it may twist and damage the microphone cable.

5.Using woodscrews, mount the base plate of the electronics module inside the lectern or wherever desired. You can remove the module cover by un- doing the screws on the side of the module.

Powering: The LM-201 is factory set for use with 12-48 volt phantom power. To change to 12-24 volt DC power, obtain from an electronics retailer a 12-24V DC power supply with a 1/8-inch phone plug connector, positive tip. Then follow the in- structions inside the electronics module cover.

Connections: Connect the LM-201 cable spade lugs to the electronics module as shown in Figure 3b. Plug the cable going to your mixer into the 3- pin XLRM output connector (see Figure 3c).

Warning: Do not lubricate the microphone swivel mount, as it may lose its friction and not stay in place. Use only mild soap and water to clean the microphone.

Tension Adjustment: If the swivel becomes loose, remove the swivel mount from the lectern and look under the mount. You’ll see a ring with two holes 180 degrees apart. Place the tips of a needlenose pliers in these holes, and rotate the ring clockwise until the swivel is sufficiently tight. Remount the unit.

Service

If the unit fails to work, replace or repair any additional mic cables, or check the power sup- ply. A Service Return Authorization (SRA) is required for product being sent to the factory for service. A SRA can be completed on line at www. crownaudio.com/support/factserv.htm. If service is required, return the microphone in its original packaging to: Crown Factory Service, 1718 West Mishawaka Road, Elkhart, Indiana 46517-9439. For further assistance or technical support call 800-342-6939.

At the factory, the electronics module is matched to your particular microphone’s fre- quency response. If you determine that just the microphone or the module needs service, send both anyway. Then we can match your electron- ics to your microphone. The serial number is on both pieces.
