The DOWN/SET BUTTON (3) is used to transfer the selected channel info from the receiver to
the transmitter for easy synchronization prior to use. Press the DOWN/SET BUTTON to start
the transfer. The TX LCD DISPLAY (17, 27) lights up indicating IR transmission is in progress.
If needed, press it again to restart synchronizing. When the synchronization is completed
successfully, the RF LED/LCD (5, 6) on the receiver will light up.
See Programming the U-1100HT/U-11100LT/GT Transmitters to the Selected Channel in the following
section.)
Instructions for Setup of Simultaneous Multi-channel Operation
The U-1100/2100 receiver is capable of nding an open channel with its Auto Scan capability.
This built-in feature is a quick, convenient way to set up many wireless systems at the same
location for simultaneous multichannel operation.
If you are using multiple transmitters at the same location, set up the rst transmitter and leave
it ON and keep 10 feet away from the receivers and 1 foot away from transmitter to transmitter.
This avoids possible duplicate selection of the same channel as already selected for the rst
receiver. Then start the Auto scan function on the second U-1100/2100 receiver. Repeat this
procedure for all receivers and transmitters to be used in your system. Finally with all the
transmitters ON, perform a range walk test in the location these systems will be used in to check
for potential crosstalk interference in this application.
If you are not satised with any of the channels scanned for a particular receiver, repeat the Auto
Scan procedure for that receiver again anytime for nding another free channel.
Connecting the Audio Output
The U-1100/2100 audio output has an adjustable Line level ¼” Unbalanced OUT (10) and xed
MIC level XLR Balanced OUT (9). The ¼” unbalanced line out is controlled by the Volume Control
(2).
For unbalanced line output connection, plug an audio cable with a ¼” mono (Tip/Sleeve) plug
into the Unbalanced Line Out jack and plug the other end into your mixing board or amplier.
Adjusting the RX Volume control will increase or decrease the audio level at the ¼” Unbalanced
Line Out only. When using the U-1100GT instrument transmitter system, connect the
Unbalanced Line Out directly to your instrument amp or preamp. At maximum receiver volume
setting, the system output is approximately +4dB higher than a direct cord-to-amp connection.
For XLR Balanced Mic Output connection, plug an audio cable with an XLR connector into the
XLR Balanced MIC OUT (9) socket and plug the other end into your mixing board or amplier
and control the audio levels from there.
Both the ¼” Unbalanced Line Out and the XLR Balanced Mic Out can be used at the same time to
connect to your mixing board, eect, or amplier.
Note: As when making any connection, make sure the amplier or mixing board volume is at the
minimum level before plugging in the receiver to avoid possible sound system damage.
Note: Only one transmitter can be used with one receiver. It is not possible to use two transmitters on
the same frequency and mix the output of these transmitters into one wireless receiver.
Your U-1100/2100 receiver is now in operational state and ready to use. Proceed to the following
instructions for the U-1100HT handheld microphone transmitter or U-1100LT/HM or GT
bodypack transmitter included with your system.
Setting up the Transmitter
The U-1100HT requires two AA alkaline or NiMH batteries to operate (do not mix types). To
