The Valcom Stacking Feedback Eliminator is a professional-grade solution engineered for clear, uninterrupted audio in demanding paging, intercom, and conference environments. Designed for installations that demand reliability and scalable performance, this compact device uses advanced suppression technology to target and eliminate feedback without compromising voice clarity. Whether you’re outfitting a single meeting room or a multi-zone campus, stacking multiple units provides flexible gain management, precise feedback control, and a clean, natural sound that keeps speech intelligible even in challenging acoustic spaces. Built by Valcom, a trusted name in professional audio, this device blends solid construction with intuitive operation to deliver dependable results in daily use.

  • Stacking and scalability: Built to be stacked with other units, the Stacking Feedback Eliminator lets installers scale their system to match room size, ceiling height, and loudspeaker arrangements. This modular approach minimizes the need for oversized single-box solutions and enables tailored coverage across zones, corridors, and auditoriums. The result is consistent feedback control from the smallest classroom to the largest venue, with predictable performance as you add more units.
  • Adaptive feedback suppression: The core feature is precision feedback elimination that preserves natural voice tone while suppressing screeching loops. By using adaptive filtering and careful notch placement, the device reduces howling and ringing without dulling the intelligibility of speech. This means cleaner announcements, clearer paging, and more comfortable listening for audiences in rooms with challenging acoustics or close-miking.
  • Easy integration with existing systems: The Stacking Feedback Eliminator is designed to work with standard professional audio gear. It integrates with typical AV racks, wall-mount options, and compatible consoles or amplifiers, allowing for seamless connections via balanced and unbalanced inputs/outputs. Its straightforward signal path minimizes phase and gain issues, so you can retrofit it into current configurations without a major overhaul.
  • Rugged build and reliable operation: Constructed for daily use in education, corporate, and hospitality environments, this device features a durable chassis suited for rack mounting or surface mounting in accessible locations. The reliable performance under continuous operation helps ensure that critical announcements—whether a campus-wide alert or a routine schedule message—come through with confidence, every time.
  • User-friendly controls and indicators: Front-panel controls and indicators provide quick access to essential functions and status. The interface is designed for technicians and Audio-Visual staff who need fast adjustments during setup, maintenance, or in-room troubleshooting. Clear LEDs and simple controls reduce the time needed to optimize system performance, so operators can focus on delivering clear communications rather than chasing feedback.

How to Install Valcom Stacking Feedback Eliminator

Installations begin with a clear plan for where the units will be located, how many you’ll stack, and how they fit into the overall signal chain. Begin by powering down the system and gathering all compatible components—mixing consoles, amplifiers, and loudspeakers that will interface with the eliminator. Position the devices in a standard equipment rack or on a stable shelf in an equipment room or AV closet, keeping them within easy reach for maintenance. Ensure adequate ventilation so units remain cool during operation, especially in high-use environments.

Connect the signal path in the order that preserves signal integrity. Start with the mixing console’s output feeding the Stacking Feedback Eliminator’s input, then route the processed signal from the output of the eliminator to the amplifier or to the next device in the chain. When stacking units, use appropriate interconnects to link each unit, following the manufacturer’s recommended daisy-chain or parallel configuration for cascading effects. Use balanced connections (XLR or TRS where applicable) to minimize noise pickup over longer cable runs, particularly in sites with high electrical interference or extensive cabling. If your installation requires multiple zones, arrange each unit to serve its designated area, maintaining consistent gain structure across the stack so that all zones maintain similar levels and feedback behavior.

Power up the system and perform a careful initial test. Begin with a modest volume and gradually increase until you encounter any feedback. Adjust the front-panel controls or software-determined parameters as needed to suppress feedback without compromising the naturalness of speech. When setting up multiple units, verify that stacking produces a consistent response across zones. Listen for any artifacts or changes in timbre and adjust notch filters, gain, or other parameters to maintain clear, intelligible sound. Document all settings for future maintenance and for consistent reproduction if you add or remove units later.

Maintenance and optimization are straightforward. Periodically check for dust in the rack area and ensure cable connections remain secure. If a new room or audience size necessitates different coverage, reposition units or re-balance the gain to preserve consistent levels and to continue delivering reliable feedback suppression. The Stacking Feedback Eliminator is designed to be a long-term part of your AV distribution chain, providing a dependable foundation for announcements, paging, and intercom communications, even as equipment and room layouts evolve.

Tip for best results: keep microphones away from loudspeakers and maintain an appropriate speaker-to-microphone distance. In rooms with unusual acoustic profiles, consider a staged approach to adding units to the stack to minimize accumulation of gain and ensure smooth, natural sound across all listening points. By combining thoughtful placement with careful adjustment, you’ll maximize the benefits of the Valcom Stacking Feedback Eliminator and protect your system from disruptive feedback without sacrificing vocal clarity.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

I appreciate that they don’t feel restrictive, allowing me to walk around my home while wearing them without any discomfort. They are also lightweight, making them easy to slip on before bed. User-Friendly: They are super easy to use—just wear them overnight, and let the socks do their magic. I love the simplicity of incorporating them into my nighttime routine. Durable Quality: The quality of the socks is impressive. They wash well and have maintained their shape and effectiveness after multiple uses. I feel confident that they will last a long time.

These worked for me!
Color: Original Grey
They worked great. I bought these for cracked sore heels. It took 2-3 weeks but my heels no longer hurt and the cracks have closed and look more like an indention than a crack now. They feel so much better, but I'll probably wear them another week just to be sure they stay healed. They look and feel like regular socks from the outside but only cover the heel with the toe open. Not think but not thick, again like regular socks. They would probably be slippery on a smooth surface the same as socks. The inside feels like rubber or something smooth at the heel. I have washed them once each pair and accidentally dried one pair in the dryer. They still seem to feel the same so I think they're fine. They're pretty inexpensive and had different colors and sizes.

Truly Helped My Cracked Heels
Color: Original Grey
I didn't include a photo cause they look exactly like their advertisement photo. I so liked the silicon-type heel lining as it kept the heel-repair cream on my heel and did not get soaked up by the sock. But, it is so, so slippery when walking around in them! Take care to be mindful when you set each foot down as the lotion can slide your heel across the sock quite a bit. If these socks were for an elderly person, I would have them only sit while using the sock - no walking around for fear of falling. I have larger ankles and found that having both the top and the bottom hems/elastic, etc. the same size to be quite troublesome and was not a nice feeling or fit on my upper hem that hit my ankle. Don't get me wrong, I am so glad that I got them and I continue to use them and they are helping my horribly-cracked heels greatly, but I find that I have to keep moving the top hem up and down so that it doesn't stay in one position as it cuts in to my ankle. My feedback and advice might be to please make the upper hem somewhat larger than the one that is on the bottom and goes over my actual foot. They really should not be the same circumference...or else make different sizes - S, M, L, etc. That's really my only complaint or "con" to ordering these. I think they are a great concept and I like the fact that I can throw them in the washer and dryer.

Actually works, and really well
Color: Original Grey
I bought these because I got them on a great deal and was quite skeptical, but they actually worked exactly as advertised and I saw a huge difference after the first night! I understand why they don’t cover the whole foot like a regular sock (it would be stifling), but it would be incredible if they made a pair that go forward enough to cover the ball of the foot. One pair lasted about 3 weeks before the moisturizer wore out (I did notice a dropoff after washing, so for best results put them on when you’re clean and just for overnight, so you can avoid washing). Apologies for no photos- no one wants to see the before photos. These work so well I’ve just come back to order more even though I’m now paying full price. Definitely, definitely recommend.
