ULTRANOISE TECHNOLOGY
ULTRANOISE technology is 2 key points:
1. Ultrasound carrier is modulated by special noise signal of audio range. The
result is a signal that is perceived by the human ear as a quiet sound like the
background AC of an unattached speaker. However, in a microphone of sound
recorder the sound turns into a loud noise that overrides all other sounds.
2. Very high efficiency of conversion of electrical energy into ultrasound. This
allows one to create powerful and energy-effective device.
CONTROLS AND INDICATORS
On the side panel there are power button (POWER), volume control of audio
interference (VOLUME) and tone controls (TREBLE) and (BASS).
On the rear panel of the jammer there are power cord and power indicator (red
LED ).
DELIVERY SET
SPYSONIC XL COMBI jammer, desktop version –1 pcs.
User’s manual –1 pcs.
USAGE
To activate the device, connect the speaker to mains and press the POWER button
on the side panel. Red LED on the back panel indicates the device is on.
Ultrasound suppressor starts working immediately after switching on.
To enable additional audio noise generator with floating spectrum (combined
mode), set the volume of the sound generator by VOLUME control. Adjusting the
tone of audio noise is made by TREBLE and BASS regulators.
ULTRASOUND JAMMER
To enable only ultrasound jammer, press POWER button on the side panel.
VOLUME control must be set to the leftmost position. It is advisable to point the
suppressor toward possible location of sound recording device.
COMBI MODE
To turn on the combined mode, turn on the device by POWER button and set the
level and tone of the audio noise generator by VOLUME, TREBLE and BASS
controls. Recommended position of the TREBLE control - at minimum, the BASS
control - at maximum. To maximize the effectiveness of suppression, the volume
of sound interference must correspond to the volume of speech. Volume and
tone controls do not affect the ultrasound part of the jammer.
CONDITIONS OF EXPLOITATION
SPYSONIC DESCTOP 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.
