What is the Behringer MicroHD HD400 and what does it do?

The Behringer MicroHD HD400 is a compact, 2-channel hum destroyer designed to eliminate unwanted hum and buzz from your audio signals. It effectively breaks ground loops, which are a common cause of noise in audio systems, ensuring a clean and clear sound. This passive device is perfect for connecting instruments, mixers, or other audio gear without introducing noise.

How do I connect the HD400 to my audio setup?

The HD400 features two 1/4-inch TRS inputs and two 1/4-inch TRS outputs. You simply connect the audio source (like a keyboard or guitar amp output) to the HD400's input, and then connect the HD400's output to your destination (like a mixer or audio interface). Its 2-channel design allows you to process two mono signals or one stereo signal.

When should I use the Behringer HD400?

You should use the HD400 whenever you experience a persistent low-frequency hum or buzz in your audio system, often heard when connecting different pieces of gear. It's ideal for live sound, home studios, or even DJ setups where ground loops can create distracting noise, ensuring your sound remains pristine.

Does the HD400 require power or batteries?

No, the Behringer MicroHD HD400 is a passive device, meaning it does not require any external power supply, batteries, or phantom power to operate. This makes it incredibly convenient for quick setup and use in any situation, as you can simply plug it in and let it do its job.
