ULTRANOISE & ULTRASOUND
Operating modes
ULTRANOISE-2
and
ULTRASOUND-2
are 2 different algorithms of
formation of ultrasonic noise.
COMMON IN ULTRANOISE-2 AND ULTRASOUND-2 MODES
Ultrasonic carrier is modulated by noise signal of audible range. In sound recorder
microphone this modulated signal turns into loud noise which covers all other
sounds. In the 2nd generation jammers, 2 ultrasonic frequencies are used, which
significantly expands the number of types of recording devices suppressed.
DIFFERENCES IN ULTRANOISE-2 AND ULTRASOUND-2
The main difference is the modulation depth of the ultrasonic carrier. Ultranoise
mode has maximum depth of modulation, which provides maximum suppression,
but the signal of the jammer is heard by the human ear as a sound resembling the
background AC sound of unattached loudspeaker. In Ultrasound mode the
jammer is almost silent, but the radius of suppression decreases approximately
1.3 times.
CONTROLS AND INDICATORS
At the back of the panel there is a power connector, red power button combined
with on/off indicator and green Ultranoise/Ultrasound switch button.
USAGE
To activate the device, just connect the power supply and press the red button. It
is advisable to point the jammer toward possible location of sound recording
device. Placing the jammer on the celling usually is not the best option, because in
such a way the jammer is closer to persons’ heads than to possible recording
devices. Often the optimal location of the suppressor is under the table, as close
as possible to the place of the probable location of an audio recorder.
SWITCHING JAMMING MODES
In
ULTRANOISE
mode the sound of the jammer is perceived by the human ear as a
light crackling. If you want the suppressor to work as quietly as possible, you
should enable silent mode
ULTRASOUND
by pressing the green button.
POWER ADJUSTMENT
If it is necessary to change the power of ultrasound, voltage can be change within
10 to 7 volts. To do this, unplug the AC adapter and change the adjusting resistor
on the side of the adapter. We supply 10V, 9V, 8V and 7V resistors. The
recommended voltage is 9V. To slightly increase power, change it for 10V. To
decrease power, use 8V or 7V resistors.
CONDITIONS OF EXPLOITATION
SPYSONIC PANEL XXL+
can be used over a wide temperature range (-20⁰C ... + 50⁰C)
with humidity up to 95%. Operating in direct exposure to rain or snow is not
allowed. In the event of a short circuit or reverse polarity,
SPYSONIC
has built-in
protection.
APPROXIMATE DISTANCES OF SUPPRESSION
SPYSONIC PANEL XXL+
provides probably the best range of suppression, but its
efficiency is not the same for various devices.
For iPhones 4 and 5 and most Chinese transmitters (bugs) jamming distance is
more than 10 m. For iPhone 6 and iPhone 6 plus the distance is 3 - 5 m. For video
cameras, microphones in headsets and laptops, suppression distance is in the
range 4 - 8 m. For some smart phones the distance of suppression may not exceed
2 m. In Ultrasound mode the radius of suppression decreases approximately 1.3
times. If microphone is covered with some cloth, the jamming distance is reduced.
