- Pannello posteriore: Features two BNC antenna inputs (ANT.A, ANT.B), two balanced XLR microphone level outputs (BALANCED A, BALANCED B) for each channel, a 1/4-inch summed line audio output (SUM), two squelch adjustment knobs, and a power input jack (12-18VDC/150mA).
U-1100GT Bodypack Transmitters
The U-1100GT bodypack transmitters are compact units designed for instrument use. They feature a metal belt clip for secure attachment.
- Fronte: An LCD display shows frequency, channel, and battery level. An infrared (IR) window is located below the display for syncing with the receiver.
- Top: Includes an external attached antenna, an ON/MUTE/OFF switch, and a 3.5mm locking mini-jack input connector for your instrument cable.
- Compartimentu di batterie: Houses two AA alkaline or NiMH batteries, providing 8-10 hours of typical operation. The frequency band label is also located here.
Antenne
Two removable swivel BNC antennas are included to enhance the operating range and performance of your wireless system. These attach to the rear panel of the receiver.
Instrument Cables
Two 1/4-inch-to-3.5mm locking connector cables are provided to connect your instruments (e.g., guitar, bass) to the U-1100GT bodypack transmitters.
Istituisci

- Connect Receiver Output: Connect the 1/4-inch SUM output from the receiver to your mixer or recording interface. Alternatively, use the individual balanced XLR outputs (BALANCED A, BALANCED B) for separate channel outputs.
- Installate e batterie in i trasmettitori: Open the battery compartment of each U-1100GT bodypack transmitter and insert two fresh AA batteries, observing correct polarity.
- Connect Instrument to Bodypack: Plug one end of the 1/4-inch-to-3.5mm locking instrument cable into your instrument and the 3.5mm locking end into the input jack on the top of the U-1100GT bodypack transmitter.
- Power On Receiver: Press and hold the POWER button on the front panel of the U-2100 receiver for one second to turn it on.
- Trasmettitori di accensione: Slide the ON/MUTE/OFF switch on each U-1100GT bodypack transmitter to the 'ON' position.
For a visual guide on unboxing and initial setup, please refer to the video below. Note that the video may show different transmitter types (handheld or lapel microphones) than your instrument-specific bodypacks, but the receiver setup and syncing process remain similar.

Istruzzioni di funziunamentu
Channel Scan and Synchronization
To ensure interference-free operation, it is recommended to perform a channel scan and synchronize your transmitters with the receiver.
- Initiate Channel Scan (Receiver): On the U-2100 receiver, press the 'Up' arrow button above 'SET A' for approximately one second to initiate an automatic channel scan for Channel A. The display will show an animated icon during the scan and then settle on the best available channel number. Repeat this process for Channel B by pressing the 'Up' arrow button above 'SET B'.
- Sync Transmitter (IR Sync): Once a channel is selected on the receiver, turn on the corresponding U-1100GT bodypack transmitter. Press the 'Down' arrow button above 'SET A' (or 'SET B') on the receiver to activate the IR search. 'IR' should appear on the receiver's display.
- Align IR Windows: Align the IR window of the bodypack transmitter with the IR window on the receiver's front panel. Hold them close together until the channel number on the transmitter's LCD display matches the receiver's selected channel. This process typically takes a few seconds.
- Segnale di prova: After synchronization, test your signal by playing your instrument. Observe the RF/AF bar graphs on the receiver's display to confirm signal reception and audio levels. Perform a sound check through your amplifier o sistema di parlante.
Volume and Squelch Adjustment
- Controlu di u voluminu: Use the 'VOL A' and 'VOL B' knobs on the receiver's front panel to adjust the output volume for each channel independently.
- Ajuste di squelch: The squelch control knobs on the rear panel allow you to adjust the receiver's sensitivity to incoming signals. If you experience unwanted noise or interference when the transmitter is off or out of range, slowly turn the squelch knob clockwise until the noise disappears. Do not set the squelch too high, as this may reduce the system's operating range.
