U-81 OCTAVO RECEIVER OPERATING INSTRUCTIONS
1. Rack-Mounting The Receiver
The U-81 OCTAVO receiver has pre-drilled holes for rackmounting. Simply attach the
Rack Mount Ears (1) on each side and fasten with supplied screws.
(Note: Do not mount the receiver in a rack directly above an amplier or other source
of high heat. This could degrade the performance of the U-81 OCTAVO. Always ensure
adequate airow and heat dissipation in any rack conguration.)
2. Installing Antennas
If not rackmounting the receiver, the two Antennas (2a) can be mounted directly on
the Receiver Antenna Input Jacks (2b) on the receiver’s back panel. If rackmounting,
antennas can be front mounted on the Rack Ear Jacks (2d), after installing the jacks
on the Rack Ears (1) provided. Use the Antenna Connecting Cables (2c) to feed the
received signal to the receiver’s antenna jacks as pictured, connecting them from the backs
of the rack ear jacks to the receiver antenna jacks. The optimal positions of the antennas
are 45° from the receiver, so 90° from each other.
3. Powering The Receiver
Powering the receiver by plugging the provided 15VDC/1000mA adaptor into the
DC INPUT jack (3) on the back of the receiver; then plug the adapter into an AC outlet.
(Note: Any 15VDC source with 1200mA capacity can also be used.) Turn volume
controls of all channels counterclockwise for minimum setting. Once the receiver is
connected to a power source, press the power switch to the ON position, Power LED
indicator (4) is ON. The TX LEDs indicator (7) and AF LEDs indicator (8) on the front
panel of the receivers will not light up at this time, but only until one or more of the eight
channels is receiving a signal from your system’s transmitters. To turn OFF, press the
Power Switch (5) to the OFF position.
4. Mute (Squelch) & RF LED Display
The U-81 OCTAVO has a preset mute (Squelch) internally for each channel for
maximum range and performance. There is no need to adjust this. In normal condition,
the RF LEDs indicator (7) should be lit when a correct frequency is received from a
transmitter. However, when the RF LEDs indicator (7) is extinguished, the transmitter
is out of range for that given location, and the user should move closer to the receiver
to re-establish the radio link.
5. AF LED Display
The U-81 OCTAVO receiver is equipped with an AF LEDs indicator (8). The AF LED
indicator lights whenever an audio signal is being received from a modulated transmitter
signal. The AF LED indicator is not a peak level indicator so it can light continuously
during audio signal input to the transmitter.
6. Connecting Audio Outputs
(Using the UH-81 handheld or UB-81 bodypack transmitters)
• For microphone use, the xed Balanced XLR out (9) or the adjustable 1⁄4” MIX
out (10) can be used. The U-81 OCTAVO audio output stage of each channel is
congured for XLR balanced microphone level when loaded by a 600 ohm balanced or
unbalanced mixer input. Make sure the Phantom Power on your mixing board in turned
off and the volume in turn down when making the audio connections. Start the receiver
VOLUME at minimum and adjust until the level is optimal.

• For each channel you wish to use, insert an audio cord with a XLR female plug into its
Balanced XLR out (9) jack on the back of the receiver. Plug the other end of this cord
into your amplier, effects or mixing board. The individual receiver outputs are all xed
mic level.
• The U-81 OCTAVO also has a MIX unbalanced output (10), which is a SUM line
level output of all the channels. To use it, just plug an audio cable with a 1⁄4” mono
plug into the MIX out (10) and plug the other end to your amplier or mixing board.
The front panel individual receiver volume controls (6) can be used to adjust any
channels level on the MIX out (10). Turn the volume controls on each of the channels
being used clockwise to near full gain. Adjust each volume up or down so that no
audio distortion is present when the ampier or mixer is set at their usual levels.
(Note: Turn the volume controls of any unused channel all the way off, full counter-
clockwise, so that only the channels being used are in the MIX output.)
• Your U-81 OCTAVO is now operational and ready to use. Now that you have completed
the above step, proceed to instructions for the UH-81 or UB-81 transmitters included
with your system.
Note:
• To prevent possible undesired noise during use, keep the volume controls of unused
channels (corresponding transmitter off) turned off in the amplier or the mixer.
The audio should only be “live” if the transmitter is on.
• As when making any connection, make sure the amplier or mixing board volume
is at the minimum level before plugging in the receiver to avoid possible sound
system damage.
• 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.

7. UH-81 Transmitter Set Up
• Release the Battery cover (11) by pressing the locking tab and slide down as
per arrow, exposing the Battery holder (12). Insert two fresh AA alkaline or NiMH
batteries, observing the correct polarity as marked, and slide the battery cover back
on to the microphone. Make sure the cover is closed completely. Fresh alkaline
batteries can last up to 10 hours in use, but in order to ensure optimum performance,
it is recommended that you replace the battery after every 6-8 hours of use. NiMH
batteries should be replaced with fresh ones recharged fully (with separate charger, not
supplied, and as per its charging instructions) whenever low or dead battery status is
indicated as per the following.
• Turn on the UH-81 by sliding the ON/STDBY/OFF switch (13) to the STANDBY
position rst (transmitter on, audio muted) or the ON position (transmitter and audio
both on). The Battery indicator LED (14) will give a single quick ash, indicating
usable battery strength. In the case of dead or low batteries, the LED will either not
go on at all or will stay on continuously, indicating that the batteries should be replaced
with fresh ones. To preserve battery life, turn the transmitter off when not in use.
• The microphone is now ready to use. The RF Signal LED (7) on the corresponding
channel of the U-81 OCTAVO receiver should now be lit, indicating a received signal
from the same frequency transmitter. When ready to speak, slide the ON/STDBY/OFF
switch (13) to the ON position.
• Adjust the volume of the receiver as per the Connecting Audio Outputs, section 6 of
the U-81 OCTAVO receiver instructions above.
[Note: Observe care in selecting P.A. volume, transmitter location and speaker
placement so that acoustic feedback (howling and screeching) will be avoided.
Please also note the pickup pattern characteristics of the microphone selected.
Omni-directional mics pick up sound equally from all directions, and are prone to
feedback if not used carefully. Unidirectional mics, as provided with the UH-81, are
more resistant to feedback, but pick up sound sources best that are directly in front
of the mic. Also, mics that are farther from the sound source, such as lavaliers,
require more acoustic gain and thus are also more prone to feedback than
close-source mics such as handheld or headworn
models that are used close to the mouth].

UB-81 BODYPACK MIC TRANSMITTER
8. UB-81 Transmitter Set Up
• Install by battery for the UB-81 transmitter by snap-opening the Battery door (15)
and inserting a fresh 9V alkaline or NiMH battery into the Battery compartment
(16), observing the correct polarity. Close the battery door to its original position
and completely cover the battery. Fresh alkaline batteries can last up to 10 hours
in use, but in order to ensure optimum performance, it is recommended that the
battery be replaced after 6-8 hours of use. A NiMH battery should be replaced with
another recharged fully (with separate charger, not supplied, and as per its charging
instructions) whenever low or dead battery status is indicated as per the following.
• Selecting Audio Input Operating Mode of the UB-81. The UB-81 is equipped with two
Input selector switches (17) located under the cover on the circuit board for selecting
the type of audio input you will be supplyin g to the transmitter. Select from the choice
of two positions: HEADWORN MIC and LAVALIER MIC (Condenser Microphones).
• There are two switches with selectable positions HM, LT together at same time.
To select inputs: (see chart on page 9)
A. Headworn Mic — set both switches to “HM”
B. Lavalier Mic — set both switches to “LT”
(Note: Use only the input audio source as per the input selected with the internal
Audio input selector switches (17) or the audio will not be optimal–a muddy or
distorted sound may result. Do not select the GT setting as the U-81 receiver outputs
are not suitable for wireless instrument use.)
• Connection for the selected input to the UB-81 is provided with a 3.5 mm Locking jack
(18) for connecting the audio input selected. Connect either the Instrument cord (19)
or the Headworn mic (20) or Lavalier mic cord (21) as desired, according to the input
selected. To secure the connection, turn the slip ring on the plug clock wise to thread
it on the jack. To unplug, reverse the process. Slip the transmitter into a pocket or
Clip (22) it on to your clothes or instrument strap (if using the UB-81 as an instrument
transmitter).
• Turn on the UB-81 by sliding the ON/STDBY/OFF switch (23) to the STANDBY
position (transmitter on, audio muted) or the ON position (transmitter and audio both
on). The Battery indicator LED (24) will give a single quick ash, indicating usable
battery strength. In the case of a dead or low battery, the LED either will not go on at all
or will stay on continuously, indicating that the battery should be replaced with a fresh
one. To conserve battery life, turn unit off when not in use.
• The U-81 transmitter is now ready to use. The RF Signal LED (7) on the
corresponding channel of the U-81 OCTAVO receiver should now be lit, indicating a
received signal from the same frequency transmitter.

UB-81 BODYPACK MIC TRANSMITTER
• Adjust the volume of the receiver as per the Connecting Audio Outputs, section 6 of
the U-81 OCTAVO receiver instructions above. [Note: Observe care in selecting P.A.
volume, transmitter location and speaker placement so that acoustic feedback (howling
and screeching) will be avoided. Please also note the pickup pattern characteristics
of the microphone selected. Omni directional mics pick up sound equally from all
directions, and are prone to feedback if not used carefully. Unidirectional mics are more
resistant to feedback, but pick up sound sources best that are directly in front of the
mic. Also, mics that are farther from the sound source, such as lavaliers, require more
acoustic gain and thus are also more prone to feedback than close-source mics such
as handheld or headworn models that are used close to the mouth].
9. Microphone Use (with either a lavalier or headworn mic)
• Secure the connection from the Lavalier (21) or Headworn mic cord (20) by turning
the slip ring on the plug into the transmitter clockwise to thread it on to the jack. To
unplug, reverse the process. To use the lavalier mic, attach it at chest level. Do not
place it too close to the mouth–a distance of about six inches usually works best. To
use the headworn mic, place it on the head and adjust the boom so that the mic is
about one inch to the side of the front of the mouth. When ready to speak, slide the
ON/STDBY/OFF switch (23) to either the “STDBY or ON” position.
• For optimum performance, an Input level control (25) is provided. Adjust the gain by
turning the control with a small screwdriver. For lavalier mic use, it is recommended
that the level be set at about 1/2 maximum. For headworn mic use, it may be advisable
to turn the gain down somewhat, depending on the volume levels expected. In either
application, experiment and set for maximum possible gain without audible distortion
on the high level peaks.
(Note: Turning down the gain too much can compromise the signal-to-noise and it is not
recommended.)

CAUTIONS AND TROUBLESHOOTING
10. No Audio
If you are not getting audio through the U-81 OCTAVO system, slide the transmitter
POWER or MUTE (STDBY) switch to ON, carefully check all connection and system
setup. Check or replace transmitter battery. Check that the receiver is powered.
The receiver and transmitter must be set to operate on the same RF channel.
11. Audio Distorted or Unwanted Sound
Remove or turn off nearby RF sources (such as other wireless system, CB radio,
CD player, computer, digital effect, ect...) Check or replace transmitter battery.
12. Feedback
Observe care in selecting P.A. volume, transmitter location and speaker placement so
that the acoustic feedback (howling and screeching) will be avoided. Please also note
the pickup pattern characteristics of the microphone selected. Omnidirectional mics
pick up sound equally from all direction, and are prone to feedback if not used carefully.
Unidirectional mics are more resistant to feedback. However, pick up sound source
best that are directly in front of the mic. In addition, mics that are farther from the sound
source, such as lavalier, required more acoustic gain and thus are also more prone to
feed back than close-source mics such as handheld or headworn models that are used
close to the mouth.
13. RF Interference
If you encounter receiving interference (from other than an operating TV station),
often it can be checked by turning off each transmitter at a time to nd the source of
causing interferences. Please note that wireless frequencies are shared with other radio
services. According to FCC regulations, wireless microphone operations are unprotected
from interference from other licensed operations in the band. If any interference is
received by any Government or non-government operation, the wireless microphone
must be cease operation or change frequencies. The above statement is valid only for
use in the U.S.A.
14. Signal Loss
Reposition the receiver and perform walk-thought test. If audio dropouts persist, locate
“dead” spots and avoid them during performance. Check receiver MUTE level setting.
Check or replace transmitter battery.

TIPS
• If the Volume Control of the receiver is set too high, it may overdrive the input of the
mixer, causing distortion. Conversely, if the output is set too low, the overall signal-
to-noise ratio of the system may be reduced. Adjust the output level of the receiver
such that the highest sound pressure level going into the microphone causes no input
overload in the mixer, and yet permist the mixer level control to operate in the normal
range (not too high and not too low). This provides the optimum signal-to-noise for the
entire system.
• Do not place the receiver antennas within 3 feet (1 meter) of another receiver or antennas.
• The receiver antennas should be kept away from any metal surface.
• For the best operation, the receiver should be placed at least 3 feet above the ground
and 3 feet away from a wall or metal surfaces. All operating transmitters should be
also at least 3 feet from the U-81 OCTAVO receiver. Keep antennas away from noise
source such as motors, automobiles, neon light, signal processor, computer, as well as
large metal objects.
• A single receiver cannot receive signal from two or more transmitters on the same
frequency simultaneously.
• For operation with an external antenna, low loss RF shielded cable should be used and
the length of the cable should not exceed 10 feet (3 meters).
• Position the receiver such that it has the least possible obstructions between it and the
transmitter. Line of sight is best!
• The transmitter and the receiver should be as close as possible but never less than
1 meter.
• Before inserting the batteries, please make sure that they are inserted according to the
correct polarity.
• Use only brand new alkaline batteries. Do not use “general purpose” batteries. When
batteries are weak, replace the batteries altogether at the same time. Do not mix and
use new and old batteries together.
• Turn the transmitter off when it is not in use. Remove the batteries if it is not to be used
for a long period.
• Headset and lavalier mic users, note that the microphone element can easily be
destroyed by the buildup of salts and minerals from perspiration and saliva. It is good
practice to put a windscreen on the mic at all times to protect it.
