RADA DUO
QUICK INSTALLATION GUIDE
CLIP, WALK AND
TALK WITH RADA DUO

RADA Duo is a lavalier wireless microphone de-
fined by its miniature and lightweight design,
high-quality audio, long battery life and precise
noise cancellation with LCF mode for especially
loud environments. Duo is focused on flexibility
and thus features clips on the receiver and trans-
mitters that can be attached to a jacket, shirt, or
belt.
The system relies on UHF wireless transmission
– it ensures outstanding signal stability and a
professional-level audio quality. RADA Duo is de-
signed as a dual-channel system, able to record
two microphone transmitters simultaneously, and
also supporting volume monitoring and adjust-
ment via hotkeys.
Duo is primarily designed for usage with AREC
Media Stations, allowing users to record present-
ers’ and guests’ voices. However, there are other
applications for it – you can also use it with cam-
eras and tablets, mobile devices, such as phones,
as well as PCs, AV audio mixers and other record-
ing and streaming devices.

WARNINGS
1. Some amount of ambient noise is unavoidable in particularly
noisy environments
2. Store in dry and clean place when not in use. Avoid storing in
hot and humid locations, as it can affect the product’s sensitivity
and tone
3. Avoid pulling by the cables and bumping them, since that can
cause the microphone sensitivity to drop or damage the cables.
4. Keep the devices dry and avoid touching them with wet hands.
RADA Duo is not waterproof, therefore do not expose it to rain or
water
PRECAUTIONS
1. Check that all cables are properly inserted when using the
devices
2. RADA Duo is equipped with rechargeable lithium batteries
that have a certain life limit as is normal for batteries. Over time
the maximum working hours will be reduced. You can take the
following steps to extend the battery life:
• Pull out the power cord after the device finishes charging.
• Fully discharge and fully recharge the batteries at least once
every three months

Configuring the devices

Devices are shipped already paired. In case you need to pair
the devices again or fix channel misalignment, follow this
procedure :
1. Power on the devices
2. On the receiver, press power button 3 times to enter
pairing (coding) mode
3. On the transmitters, press “+” button three times to do
the same

Troubleshooting
1. Objects and walls can block the devices and reduce
effective range. In crowded environments particularly,
human bodies attenuate radio waves, and thus it is im-
portant to keep the devices free from obstruction. If you
are getting interference or low signal, try clearing the ob-
stacles
2. When using outdoors or speaking directly into the
microphone, it is recommended to use the windshield to
prevent distortion and wind background noise
3. If you are experiencing audio issues, check that the
cables are properly connected
4. If you are not getting audio, make sure that the devic-
es are properly paired (coded). Follow the pairing guide
above if needed
5. It is possible to mute the devices. If you are not get-
ting audio, please check the volume level on the devices
6. Try switching to a different channel if you are still ex-
periencing interference
7. If your problem is not resolved by any of the above
suggestions, please contact a-dena.com for further tech-
nical support
