With the external speaker used together with the device, it lets you organize a more effective system that protects your conversations from a recording by directing sources of ultrasound from different directions. The speaker is equipped with 4 ultrasonic transducers and connects to the device via a mini-jack 3,5 mm port, up to two speakers can be connected to one jammer by using a splitter.

The device is powered from a 110/220V power source via an adaptor (included). You can increase the effectiveness of the Microphone Suppressor in silent mode by connecting one or two additional ultrasonic speakers. By using the external speaker, you will be able to protect your meeting room from spyware more reliably. By itself, the jammer offers protection directly in front of you and additional speakers generate interference from other sides. In this case, ultrasonic interference becomes denser and more effective in jamming spyware.

How to correctly place ultrasonic speakers:

If you have only one speaker place it under the table… Or point the side with transducers towards the other person while the jammer itself will be lying on the table in front of you. When using two speakers, usually one speaker is placed under the table and another one is placed on the wall or shelf. To connect 2 speakers to a single device, use a splitter for 2 mini-jacks 3,5 mm
