The J Portal is a device that is used to amplify and shape the incoming audio from a sweeping Spirit Box or Phone app designed for EVP capture.

​

Runs on 12 AA Batteries (not included). This is to allow for maximum run time with 6 batteries operating the two effect pedals, and 6 batteries operating the amplifier.

​

OR...Choose the Rechargeable power supply that powers the entire device without batteries!

​

The Noise reducer helps to eliminate much of the static associated with sweeping radios. The reverb helps to shape the sound.
