The SA-HumDropper eliminates ground loops, hum, and electrical interference that plague live sound setups and studio recordings. This passive noise isolation device solves the annoying buzz and hum issues that occur when connecting microphones to mixers, mixers to amplifiers, or when running long cable runs in electrically noisy environments.

The unit works by isolating audio signals from ground loops and electrical interference without requiring external power. Built around a high-quality transformer with XLR male input and XLR female output, it maintains signal integrity while filtering out unwanted noise that can compromise your mix.

The SA-HumDropper handles line-level signals and works with both powered and passive PA systems. Its compact, durable black housing integrates seamlessly into any professional audio setup, and the passive design means it never needs AC power or batteries to function.

Use it to clean up signals between your mixer and power amplifier, eliminate hum from long microphone runs, or solve ground loop issues when connecting multiple pieces of equipment. The device is particularly valuable for mobile DJs and bands who perform in venues with questionable electrical systems, or for permanent installations in churches and schools where multiple audio sources create ground loop potential.

Simply insert the SA-HumDropper inline between your audio source and destination using standard XLR cables (sold separately). The unit comes ready to use out of the box with professional XLR connectors that ensure reliable connections show after show.

Frequently Asked Questions

Will the SA-HumDropper work with my powered speakers?

Yes, the SA-HumDropper works with both powered and passive speaker systems. Since it's a passive device that doesn't require power, you can use it anywhere in your signal chain where you have line-level audio signals and XLR connections.

What cables do I need to use the SA-HumDropper?

You'll need standard XLR cables to connect the SA-HumDropper inline between your audio source and destination. The unit has an XLR male input and XLR female output, so it connects like any other device in your signal chain.

Where should I place the SA-HumDropper in my audio setup?

Insert the SA-HumDropper between any two pieces of equipment where you're experiencing hum or ground loop issues. Common placements include between your mixer and power amplifier, between a microphone and mixer input, or anywhere you have long cable runs that pick up electrical interference.

Can I use multiple SA-HumDroppers in the same system?

Yes, you can use multiple units throughout your system wherever ground loops or hum issues occur. Each SA-HumDropper works independently to isolate that particular signal path, so using several units won't cause any interaction problems.

Will this fix hum issues in large venues with poor electrical systems?

The SA-HumDropper effectively eliminates ground loops and electrical interference regardless of venue size. It's particularly valuable in older buildings, outdoor events, or any location where multiple pieces of equipment create ground loop potential or where electrical systems introduce noise into your audio signal.
