APF-D Processor

APF-D Processor

Regular price $249.00 Sale

New product from the makers of the REM Pod and SB7T!


The APF-D (Audio Playback Filter with Display) processor is a fantastic new tool that works with your SB7T Spirit Box to discover your best EVPs yet. The APF-D is a real time recorder that continues to record during your session even when you back and listen to an EVP - so you never miss an EVP again! This nifty device will record and play back the audio. You can go back and listen to it again but still receive EVPs without missing a beat. The audio can be adjusted through the four control buttons for a more in-depth analysis of the received communication. The audio cannot be transferred from the AFP-D. Therefore, be sure to always record the session with a Digital Voice Recorder. 

It will run for up to four hours when using the included rechargeable 9Vdc battery. Bluetooth receivers will convert your Spirit Box or Ghost Box frequency scanner to have Bluetooth function and allows you to have the choice to wirelessly connect to the APF-D.
