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 amplier, 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 amplier 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 ampier 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 amplier or the mixer. The audio should only be “live”
if the transmitter is on.
• 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.
• 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.
