Microphone Lift ML-2011

Installation Instructions

Structural attachment points will depend upon your specific installation. The
MicLift is designed to hang above the finished ceiling so your microphone is
slightly below the bottom of the finished ceiling. The actual mounting height will
vary depending upon your architectural situation. Structural channel and
threaded rods are common methods to install mounting points at the appropriate
height above the finished ceiling. The unit is shipped with a ¾” diameter conduit
that is 2” long reference to the right of figure 3.

NOTE

The lift is shipped fully assembled for installation into an unfinished ceiling application.
To install in a finished ceiling, you must disassemble the lower trim ring prior to
installation into the finished ceiling or ceiling tile.

The MicLift is designed to operate via our three-button remote or contact closures. See
the Control Interface section for control assignments.

The unit is designed to be mounted above the bottom of the finished ceiling.

Do’s and Don’ts

** Do not operate the lift up when the microphone cable is swinging – unit can jam.

** Do not replace or extend the factory-installed microphone cable.

** Do not operate the lift without the factory-installed weight (located at the end of the
cable) The weight is also the upper limit switch activation mechanism.

** When using directional microphones operate the lift 30 times to relax the cables
memory. The lift is cycled more that 30 times before shipping. The solenoid will get hot
if the unit is run continuously and could stop normal operation, so allow a couple
minutes between each cycle. Adjust the direction of the microphone after lengthy
operation.

MINIMUM WEIGHT CAPACITY: 2.5 OZ - MAXIMUM WEIGHT CAPACITY: 9 OZ

The weight that is provided with the lift is 2.5 ounces. Call tech support if your
microphone assembly is over 6.5oz.
