Introduction
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.
Cautions
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.
Note
If this equipment causes 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 15 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.
UX-1620 Wireless System
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 863.125 MHZ to 864.875 MHZ.
The systems available are:
UX-1620M- with two UM-68hand held microphone transmitters.
UX-1620L- with two UB-68Lbelt pack transmitters with two lavalier mics.
UX-1620H- with two UB-68Hbelt pack transmitters with two headset mics.
UX-1620ML- with one UM-68hand held mic and one UB-68Lbelt pack transmitter with lavalier mic.
UX-1620MH- with one UM-68hand held mic and one UB-68Hbelt pack transmitter with headset mic.
UX-1620 Receiver Operation
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 15 selectable frequencies so that you can choose the one with the least amount of interference. The illustration shows the dip switch settings for the 15 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.
7.Adjusting the squelch on the receiver can eliminate such problems as bleeding that occurs from using several systems at the same time or interference from local television. To adjust the squelch, place the small plastic tool (included with the unit) in the hole marked SQ (squelch) at the back of the unit, and slowly turn the tool to adjust the output level to just above the level of background noise. Setting the squelch too high will reduce the range of the system. Setting the squelch too low will increase the level of unwanted noise.
