QUICK INSTALLATION GUIDE
CLIP, WALK AND
TALK WITH RADA DUO

RADA Duo is a wireless microphone system with a minia-
ture and lightweight design, high-quality audio, extended
battery life, and precise noise cancellation, including the
LCF mode for particularly loud environments. The Duo pri-
oritizes flexibility and features clips on both the receiver
and transmitters, allowing them to be easily attached to
jackets, shirts, or belts.
The system utilises UHF wireless transmission to guaran-
tee exceptional signal stability and professional-grade
audio quality. RADA Duo is designed as a dual-channel
system capable of processing audio from two microphone
transmitters simultaneously. It also supports volume
monitoring and adjustment through convenient hotkeys.
Duo is primarily designed for use with AREC Media Sta-
tions, enabling users to capture the voices of presenters
and guests. Nevertheless, it has a variety of other applica-
tions. You can also utilise it with cameras, tablets, mobile
devices (such as phones), PCs, AV audio mixers, and other
recording and streaming equipment.

WARNINGS
1. A certain level of ambient noise is inevitable in espe-
cially noisy environments.
2. Store the product in a dry and clean area when not in
use. Avoid storing it in hot and humid locations, as this
can impact the product’s sensitivity and tone.
3. Refrain from pulling or bumping the cables, as this
can lead to a decrease in microphone sensitivity or
damage to the cables.
4. Ensure the devices remain dry and avoid handling
them with wet hands. Please note that RADA Duo is not
waterproof; therefore, refrain from exposing it to rain or
water.
PRECAUTIONS
1. Ensure that all cables are correctly inserted before
using the devices.
2. RADA Duo is outfitted with rechargeable lithium bat-
teries, which, like all batteries, have a finite lifespan. As
time passes, the maximum operating hours will diminish.
To prolong the battery life, consider the following mea-
sures:
•Disconnect the power cord after the device com-
pletes charging.
•Completely discharge and recharge the batteries at
least once every three months.
