P-SB11 Spirit Box 

The SB11 is the fastest sweeping Spirit Box available giving it a higher probability of creating clearer and more EVPs. The SB11 has been used consistently on paranormal TV shows and investigations to capture remarkable EVPs that relate to the investigated site.

How Does it Work?

The white noise of the SB11 and the fast scanning of radio frequencies is believed to provide the energy and transmission spirits need to get their voices through. The SB11 also features Temperature Detection Deviation to - or + 5 degrees F. Sudden drops in temperature indicate simultaneous paranormal activity. The red flashlight makes the P-SB11 Spirit Box night vision friendly and has minimum interference with capturing video and photos during your paranormal investigation.

How to Use

When using the P-SB11, you can choose between AM or FM, or run both at the same time in either forward or reverse while choosing the rate of sweep. It also has Dual Simultaneous Audio Outputs for simultaneous dual sweeps in either FM or AM. There are 2 Audio Output jacks, one for AM and one for FM. Running AM and FM at the same time creates clearer EVP transmissions. Turning off the antennae reduces the pick up of radio stations. Don’t forget your Voice Recorder so that you can listen to what you captured later!

You get the clearest EVPs by using this configuration: SB11 through an ANC-Mini that is then connected to a Portal. The ANC-Mini has one Audio Input Channel. When using an SB11, if you want to use both AM and FM channels simultaneously, you have to add a small mixer in between the SB11 and the ANC-Mini, such as for example the Maker Hart JUST Mixer S.
