It also includes ancillary equipment like repeaters, power supplies, and remote controls to enhance the monitoring capabilities.

1. Versatile and modular UHF Audio Monitoring system.
High audio quality, low power consumption and
miniaturised dimensions thanks to the patentedTMVWB
transmission system.
Ancillary equipment also allows re-routing of the audio
signal through several types of communication channels.
UHF AUDIO MONITORING
TMWB
The Time Modulation Very Wide Band
(TMVWB) is a pulsed transmission
technique developed and patented by
BEA.
This proprietary modulation reduces the
probability of detection and interception
with RF detectors or other conventional
sweeping techniques and drastically
reduces the average power consumption
of the transmitter, allowing operating
times over 30 times longer than
conventional transmitters with the same
peak output power level.
TMVWB devices produce an excellent
audio quality thanks to the wide
bandwidth and high dynamic range, and
are particularly indicated for long term
deployments using small battery packs.

2. The TMVWB family of transmitters is characterised by a thin package, making it an ideal candidate for deployments where deep concealment
is paramount. Available in several versions, each one developed to answer specific operational requirements and fully compatible with all
other system components, BEA’s micro transmitters can also be remotely controlled by an external miniature RF Switch.
Transmitters
Micro2 NT
Represents the basic transmitter of the
TMVWB family and is characterised by an
exceptionally small footprint. Its very low
power consumption allows operating
times in excess of 700 hours using a
standard 9 volt Lithium non rechargeable
battery.
Adoption of the latest generation of
semiconductor devices and a carefully
designed layout ensure frequency
stability and power efficiency. It can be
easily concealed, and includes a thin wire
antenna for quick transmitter installation
and rapid system deployment.
Micro2 HP NT
A high powered version of the Micro2 NT
is also available in order to provide a
robust radio link in situations where
longer distances between the target and
the observation post may be required.
The addition of an internal RF amplifier
increases the operational range of the
Micro2 HP NT transmitter whilst
maintaining power consumption well
within the capability of battery packs.
The built-in AGC ensures an optimal
audio level even in difficult acoustical
environments.
Micro3
A revised modulator gives Micro3 an
extended audio bandwidth of up to 8
KHz, providing exceptional speech
intelligibility even in reverberant
acoustical environments.
The built-in automatic microphone gain
control ensures that an optimal audio
level is transmitted at all times,
irrespective of the acoustical level in the
environment.
Micro2 ST
Micro2 ST pushes the boundaries of
concealment & miniaturisation.
This special-purpose transmitter uses a
proprietary low profile radiator and
matching network design instead of the
usual 1/4 wave wire antenna.
The solution decreases its effective
footprint and thus allows rapid
deployment in confined spaces without
the need to worry about the placement
of the antenna.
Micro2 Magnetic
Micro2 Magnetic is a coin-shaped
transmitter with microphone, antenna
and battery embedded in a compact
package.
The magnetic support allows quick
installations onto metal surfaces that,
thanks to our proprietary matching
network, will also act as an antenna.
Easy to use and to conceal: once set up,
the two non-rechargeable Lithium
batteries ensure up approx. 200 hours
working.
