Programming Ramping Distance
You may determine the location where the lift slows its acceleration. Programming can
only be done with the three-button control. If other methods of triggering the lift are
normally used, first program the lift with the remote and then configure the lift for the
other trigger method.
1 Send lift to top position (‘Up’ button).
2 Press and hold ‘Stop’ button for 10 seconds.
3 Press the ‘Down’ button. Lift will travel down. Press ‘Stop’ at the position where
you would like the microphone to begin slowing down. We recommend no less
than six inches below the finished ceiling. THIS MUST BE DONE IN ONE
MOTION. DO NOT PRESS UP, DOWN, OR STOP FOR FINE TUNING OF
POSITION.
4 At proper position, press and hold the ‘Stop’ and ‘UP’ buttons for 10 seconds.
5 Lift is now set. Press ‘Up’ to send the lift to the home position. Press ‘Down’ to
lower the lift, and ‘Up’ to send it to home position and verify where the ramping
point is. If you start the procedure and wish to quit after step 2, you must reset
power to the lift before normal operation will resume.
Refer to figure 2. The microphone lift is held in place by a solenoid brake
mechanism, so when the lift is told to move the brake will pull back and the
stepper motor will run to the lift to the desired programmed location.
Microphone Cable
The balanced microphone cable is connected to the 3-pin XLR. The color code of the
cable is braided/ground – pin 1, Blue/Blue with white stripe – pin 2, White/white with
blue stripe – pin 3. It is very important that the weight is on the cable. If the weight is
removed and you operate the lift, YOU WILL DESTROY THE MICROPHONE AND
LIFT!
Also, make sure any splice is below the weight near the microphone.
