Gemini Industries UX-1620 Operation Manual page 2

Congratulations on purchasing a Gemini wireless system. This state of the
art unit includes the latest features backed by a three year limited warranty.
Prior to use, we suggest that you carefully read all the instructions.
1. All operating instructions should be read before using this equipment.
2. To reduce the risk of electrical shock, do not open the unit. There are NO
USER REPLACEABLE PARTS INSIDE. Please refer servicing to a
qualified service technician.
3. Do not expose this unit to direct sunlight or to a heat source such as a
radiator or stove.
4. Dust, dirt and debris can interfere with the performance of this unit. Make
an effort to keep the unit away from dusty, dirty environments, and cover
the unit when it is not in use. Dust it regularly with a soft, clean brush.
5. When moving this equipment, it should be placed in its original carton
and packaging. This will reduce the risk of damage during transit.
6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
7. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY
CONTROLS OR SWITCHES.
Gemini wireless systems are the type accepted under FCC rules parts 74
and 15. Licensing of Gemini equipment is the user's responsibility and
licensability depends on the user's classification and application.
This equipment has been tested and found to comply with the limits set forth
under part 15 and 74 of FCC rules. This equipment operates at a frequency
that has been authorized by the FCC. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does
cause interference to radio or television reception, try one or more of the
following suggestions:
1. Change the frequency you are using to another one of the 16 selectable
frequencies. See the instructions for selecting frequencies for more
information.
2. Repoint or relocate the receiving antenna.
3. Plug the equipment into a socket on a different circuit.
Remember, any changes made to the unit without authorization from
Gemini will void your warranty.
The UX-1620 wireless system has two separate mic-transmitters that
transmit to one unit which houses two receivers.
The different systems available all operate on a UHF high band frequency
between 790.375 MHZ to 805.875 MHZ.
UX-1620M - with two UM-68 hand held microphone transmitters.
UX-1620L - with two UB-68L belt pack transmitters with two lavalier mics.
UX-1620H - with two UB-68H belt pack transmitters with two headset mics.
UX-1620ML - with one UM-68 hand held mic and one UB-68L belt pack
transmitter with lavalier mic.
UX-1620MH - with one UM-68 hand held mic and one UB-68H belt pack
transmitter with headset mic.

1. Remove all packing materials. Save the box and packing material to
transport the unit in the unlikely event that the unit requires service.
2. The UX-1620 has 16 selectable frequencies so that you can choose the
one with the least amount of interference. The illustration shows the dip
switch settings for the 16 frequencies.
Since the UX-1620 receiver uses two mic-transmitters, you must set
channel 1 and channel 2 to different frequencies from one another. The
dip switches for the receiver are located on the front panel. The dip
switches for the belt pack transmitter are located on the side of the belt
pack. The dip switches for the hand held mic can be accessed by
opening the battery holder on the side of the mic.
Set the receiver dip switches for channel 1 (the set of four dip switches
on the left) and the belt pack transmitter or hand held mic transmitter
that you will use with channel 1 to matching frequencies. Set the receiver
dip switches for channel 2 (the set of four dip switches on the right) and
the belt pack transmitter or hand held mic transmitter that you will use
with channel 2 to matching frequencies.
3. Plug the AC adapter into the rear of the receiver where the jack is
labeled DC 12-18V. Then plug the adapter into an appropriate AC outlet.
Note: The adapter is available in 120V AC or 230V AC.
4. The receiver is supplied with 2 balanced XLR output connectors and one
1/4" output connector. The UNBALANCED OUTPUT is used to connect
the receiver to your amp, effects or mixer mic jack using a standard mic
cable with a 1/4" connector. The BALANCED OUTPUTS are used to
connect the receiver to your amp, effects or mixer mic jack using
standard mic cables with XLR connectors. We recommend using the
balanced outputs if the cables to your amp, effects or mixer mic jack are
10 feet or more. The BALANCED OUTPUTS have three separate
conductors, two of which are signal (positive and negative) and one
shield (ground). Pin 1 is ground (shield). Pin 2 is signal hot (positive). Pin
3 is signal cold (negative). You can use both the XLR and 1/4" outputs at
the same time if you choose to.
There is a MIXING switch located between the XLR and 1/4" output
connectors that allows you to adjust the output signal being sent from the
XLR outputs. When the MIXING switch is in the OFF position, the XLR
output for channels 1 and 2 are separate. When the MIXING switch is in
the ON position, the XLR output for channels 1 and 2 are mixed, so that
both XLR outputs have signal from both channel 1 and channel 2. In
other words, channel 1 and channel 2 are combined into both output
jacks.
5. Point the antenna upward. Switch the power to the ON position.
6. Adjust the volume using the LEVEL controls on the front panel.
