Nady Systems OCTAVO U-81 Owner's Manual - page 5
• 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 amplifier, effects or mixing board. The individual receiver outputs are all fixed
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 amplifier 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 ampflier 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 amplifier or the mixer.
The audio should only be “live” if the transmitter is on.
• 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.
• 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.
