OPTOGATE Mic Lift V2 User manual

User instructions for the Mic Lift V2
The Mic Lift V2 Motorized microphone Stand is our answer to the many requests from customers. The
motor and the main mechanical parts are completely mounted in the foot in order to keep the visible parts
small and make the Mic Lift V2 usable for TV shows and other applications where smart solutions are
required. The Mic Lift V2 can be controlled from MX lighting desk as well as with an extra remote
control which supplied together with the Mic Lift V2. The remote control and the Mic Lift can be
connected via a 3 pin Mic cable or a Multicore. 50 different presets/heights can be saved and recalled
with the remote control. The actual height of the Mic Lift V2 is displayed on the rc. The surface of the rc is
clear with three push buttons and with a minimum number of program layers very easy to use.
Installation
ecide whether the unit is to be powered by batteries or an external 12V C power supply.
Battery Powering:
On the botton side is the battery box. The cover is fastened with 2 cross-head screws. Remove
the cover and insert 8 AA alkaline type batteries – ensuring correct orientation. Replace the cover.
The remote control is powered by one 9V block battery. The rc battery lifetime is between 18 and
30 hours, depending of the quality of the battery and the frequency of the use. It is time to change
the batteries when the speed of the motor is slow or when the current sensor does not work
correctly anymore. Remove the 4 screws on the bottom cover, remove the bottom and change the
battery, then replace the bottom cover.
External powering:
Any kind of 12 Volt, 1 Ampere power supply will do this job. Just remove the battery package and
connect a 12 Volt supply. Please take care of the polarity of the supply, otherwise you might
damage the controller board. However, an AA batterypackage will usually have a long lifetime and
there is in most cases no need for an external supply.
RS 85 or DMX512 Operation:
The RS485 interface allows control with the rc as well as with a dmx desk. We recommend the
use of the rc because you have indication of the adjusted height on the rc display and the rc will
only send data when a new height is requested. A dmx desk will always send data even when
they are not required and it could happen that an adjusted value can change between 3 least
significant bits due to the fader tolerances in the light desk. However if the artist will change the
height by foot then the Mic Lift V2 will not accept a new dmx value unless the new value is 2 bit
different from the old value. The XLR connectors in the Mic Lift V2 and in the rc are wired in
parallel in order to use any input or output of an existing sound multicore for the data transfer.
Connect the remote control and the Mic Lift V2 on both sides of an existing multicore and the
operation can begin. Please note that an accidential polarity change somewhere on the cable
between rc and Mic Lift V2 results in faulty data.
Local operation:
The Mic Lift V2 can be controlled via the implemented foot switches. A push on the right switch will
increase the height and a push on the left switch decreases the height. The program buttons and the
power switchs are almost flat to the cover in order to minimize the risk of an accidential push on
these buttons by a foot! The local footswitches can be disabled by pressing the “M3” button for 2
seconds while powering on the Mic Lift V2. (A “*” in the display of the Mic Lift V2 will indicate this
mode). ue to the toothbelt in the new version there should no re-adjustment of the decoder wheel
necessary anymore.

General points to observe
Ensure that all users of the Mic Lift are familiar with its operational requirements and the environment in
which it is to be used. The operator must have a good view of the Mic Lift V2 at all times. Please take
care that the height of the stand is not be changed by hand because the tooth belt can be damaged by
excessive force. If this happens you need to open the device and need to change the belt what is
availabe from us.
LCD background light: You can disable the lcd light in the Mic Lift V2 device by opening the device and
remove the jumper what is on the rear side of the pcb board. Please take care that no connector on the
board will be detached when assembling again. However, the currect consumption of the lcd light is very
low and will not affect a big difference in the battery life time, regardless if with or without lcd light.

Service infos for the OPTOGATE Mic Lift V2
The Mic Lift V2 case is made from ST37 steel and useable for professional use. However, it might be
necessary to tightening the tooth belt after a while of frequently use. Just remove the cover of the Mic Lift
V2, remove the 2 screws of the motor block and pull the motor block a bit back to the outside. Fix the
screws in this position. A clearance of about 5 mm at the middle of the visible part of the belt is ok and
there is no need to make the tooth belt very tight. The minimum height can be adjusted by turning the
decoder wheel carefully when the tooth belt is loose.
