ANC-Mini Spirit Box Noise Reducer

product sample photoClean up the noise from your spirit box sessions.

The ANC-Mini is an Adjustable Noise Control used to clean up and amplify all of your ghost box sessions. This helpful device is compatible with most major spirit box / radio sweeping devices including the SBox, SB7, SB11 and some others with a designated output for sweep audio.

One touch clarity.

With just one touch, it is easy to use and simply to adjust for control.

In short, this accessory helps remove excess white noise and static while allowing the spikes we're looking for to come through. Utilizing a proprietary software algorithm, the ANC dynamically adjusts the audio properties which enables a more clear spirit response that can be better heard and deciphered by the user.

A must-have accessory for spirit boxes.

The ANC-Mini is compatible with SBox, SB7, SB11 and some others with a designated output for sweep audio. You will also need a speaker to hear the cleaned ouput from the ANC.

Need a spirit box to go with this? We've got you covered.


You MUST have a speaker or headphones to use this device. The ANC does not have its own speaker built in. Speaker shown in the photo right is sold seperately as an option above.

If using your own speaker, it must have a 3.5 jack (male or female) with clearance enough for the other input jack. If you have one of the ball speakers that used to come with the SB7, that will work great.


* This listing is for the purchase of ANC-Mini ONLY. Speaker and spirit boxes shown in photos are for demonstration purposes to show how they connect together. Spirit boxes and speakers are sold seperately. See our selection of ghost boxes that go well with this product below.

    This is a great little device. It does exactly what it's supposed to. It's a must for anyone who uses the Sbox or SB7.

    This device is definitely a game changer. I will be using this when we investigate the Haunted Hinsdale/Dandy House in New York. I can't wait to share how it performs in a highly active location.

    Worth it!

    This is a must-have with your spirit box. It work well with our SB-7,. It eliminates most of the excess white noise without spending a small fortune on a portal.

    Tiny and mighty!

    This little beauty is amazing! I've been getting clearer sweeps on a non SB11 unit. At first I didn't think it would work but as long as you have a true spirit box device with an input and output jack it works perfectly! I highly recommend any investigator picking one up!

    Serious Game Changer

    The ANC-mini removes excess white noise and static effortlessly. Small enough to attach to SBOX or SB7-11 with the added Velcro. Cables included.

    A “Must Have” for any Spirit Box Radio

    Posted by Ryan L Randall on May 18th 2022

    I bought this for my SBox. I am extremely satisfied with the results. This will clean up 95% of the static. It does need an additional “output” speaker. I agree with recommendations and would also buy the “Premium Speaker for ANC” sold by GhostStop. I hope this helps.

    Oh, this is a must have! I love that you have control over how much white noise is heard. We used it to do an investigation at an bar and the voices were clear and undeniable. Telling everyone! Love It!
