SB-7 Spirit Box REV4 (with free ball speaker) for Ghost Hunting (with new noise cancellation circuit!)
DAS is using a new noise cancellation circuit that they believe is a great improvement. DAS added noise reduction on the FM channel and we brought back the AM. The FM and AM are balanced equally so both can be heard. The refinements of the new version are made specifically into the AM bandwidth. You will hear more radio detail in the AM bandwidth, it will be clearer during the sweep session.This new Revision 4 now sweeps from 88.0 to 108.0 in the FM frequency range. The B-PSB7 Spirit Box is a great compact tool for attempting communication with paranormal entities. It uses radio frequency sweeps to generate white noise which theories suggest give some entities the energy they need to be heard. When this occurs you will sometimes hear voices or sounds coming through the static in an attempt to communicate.
This new model allows for both FM and AM sweep modes, for balanced amplification. Now with balanced frequency power and noise reduction you can expected cleaner results and greater clarity while sweeping.
This unit utilises a milli-second adjustable Forward or Reverse frequency "sweep" technique coupled with a proprietary high frequency synthetic noise or "white noise" distributed between frequency steps. There are two discreet audio outputs; (1) earphone or external speaker, and (2) internal speaker. It also features a bright LED back light display with manual ON/OFF select ideal for viewing in the dark.
