Audio Level and Peak LED Indicator
The U-800 receiver has a 5 bar AF LCD (7) display that typically shows a few bars
indicating normal level audio signal from the transmitter. Occasional flickering of
the fifth AF LCD (peak level) on loud inputs to the transmitter is normal. If the AF LCD
lights up full bars continuously decrease the input audio level to the transmitter or
overload distortion may result.
Connecting the Audio Output
The U-800 receiver has two type of outputs available, an adjustable level ¼”
UNBALANCED LINE OUT (19) and a fixed level MIC out BALANCED MIC
OUT XLR JACK (22). The ¼” unbalanced line out is controlled by the VOLUME
CONTROL (21).
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 amplifier. Adjusting the Volume control will increase or decrease the
audio level at the ¼” Unbalanced Line Out only.
(Note: When using the UB-800 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 balanced Output connection, plug an audio cable with an XLR connector into the
Balanced Mic Out XLR Jack socket and plug the other end into your mixing board or
amplifier 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, effect, or amplifier. Please follow below drawing for the audio cable/
connector wiring.
Your U-800 receiver is now operational and ready to use. Proceed to the following
instructions for the UH-800 handheld microphone transmitter or UB-800 bodypack
transmitter included with your system.
Note: As when making any connection, make sure the amplifier 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.

or available channels in each group. The previous group and channel used is stored
in memory automatically when receiver and transmitter are turned off after operation.
Selecting a different group on the receiver in subsequent use will display a differ-
ent channel as previously selected for that group, however, the transmitter will need
again to be sync’ed to that new frequency to complete the system setup for operation.
Receiver ASC/IR Sync GR/CH (Frequency)
If different frequencies than previously stored in both the receiver and transmitter
memories are needed, there are three ways to program the receiver and then sync

5 seconds, the receiver will start process automatically with no further user action
required. A running bar in a clockwise direction on the LCD DISPLAY (5) shows
the scanning process which normally takes about two seconds. When it finds an
interference-free channel, the receiver stores the channel for use, and it will begin

After selecting a group, press the MENU BUTTON twice for channel selection

the frequency chosen will be displayed. See section “11. U-800 Frequency

press the MENU BUTTON once or wait a few seconds for IR MENU, and then
press UP BUTTON to start IR programming.
This completes the GP/CH (frequency) programming. The next section outlines the
procedure for sync’ing the receiver’s programmed channel to the transmitter.
