RECEIVER
FRONT PANEL FEATURES
1. POWER SWITCH
Depress to power the receiver. The RED led indi-
cates power to the unit.
2. LEVEL CONTROL
Adjusts the audio level to your amp or mixer. If
distortion occurs, reduce the level.
3. SQUELCH CONTROL
The squelch control is preset at the factory,
but can be adjusted if you must use the system in an area with consid-
erable RF interference. If there is audio output from the receiver when
your transmitter is off, adjust the squelch control so the system will
receive the signal from your transmitter but “squelch” or eliminate the
unwanted background RF noise. This adjustment can cause a reduction
in useable range of the wireless transmitter, so set the control to the low-
est position that reliably mutes the unwanted RF signals.
4. ACTIVE DIVERSITY CHANNEL LED
(On U7000 UHF Receiver
only) The A and B LED indicate which antenna signal is being used. This
diversity receiver will automatically choose the stronger of the two.
5. AF LEVEL LED
The AF level is displayed by an LED meter, which indi-
cates the strength of the audio signal received.
6. RF LEVEL LED
The RF level is displayed by an LED meter, which
allows you to estimate the RF power with which a transmitted signal is
received. If less than 2 LED, reception will become noisy.
7. ANTENNA
“A”
Antenna for receiver “A.”
8. ANTENNA “B”
Antenna for receiver “B.”
9. MOUNTING ADAPTERS
For mounting the receiver in any stan-
dard 19” rack, attach adapters to receiver with screws supplied.
FRONT & REAR PANEL CONTROLS
1.
Use only fresh alkaline batteries.
2.
Position the receiver so that it has the fewest possible obstruction between
it and the normal location of the transmitter. Line-of-sight is best.
3.
The transmitter and receiver should be as close together as conveniently possible.
4.
The receiver antenna should be in the open and away from any metal or cement walls.
If in a rack, have the unit on top or angle antennas outward away from the metal rack.
5.
A receiver cannot receive signals from two transmitters at the same time.
6. Each transmitter/receiver system operates on a factory-aligned, crystal co trolled
frequency. Look on the back of the receiver to obtain the channel number. This
number must match the transmitter if you purchase a replacement transmitter.
7.
Turn the transmitter off when not in use. Remove the battery if the trans-
mitter is not used for a period of time.
TIPS TO OBTAIN THE BEST RESULTS
REAR PANEL FEATURES
10. ANTENNA JACK “A”
Antenna connector for receiver ”A.” Attach
the antenna directly or extend it with an antenna cable for front mounting.
11. ANTENNA JACK “B”
Antenna connector for receiver “B.” Attach
the antenna directly or extend it with an antenna cable for front mounting.
12. DC POWER INPUT
Use AC power adapter, which supplies 12V DC.
13. OUTPUT LEVEL
If the signal going to your amp or mixer is too loud or
distorted, set the output level to Low. If you lack volume, set the switch to High.
14. FUSE
Turn the unit OFF and unplug the power supply before checking or
replacing the fuse. Use a philip screwdriver to remove the fuse holder.
Replace the fuse with the same rated fuse.
15. UNBALANCED AUDIO OUTPUT JACK
1/4” phone jack. Can be
connected to an unbalanced input of a mixer or tape recorder.
16. BALANCED AUDIO OUTPUT JACK
XLR-type connector. A stan-
dard 2-conductor shielded cable can be used to connect the receiver out-
put to a balanced input on a mixer.
17. FREQUENCY CODE
The transistor and receiver must have the same
frequency number.
