Handy buzz-hunting tools
Unwanted buzz can ruin otherwise excellent audio in the blink of an eye. The HE18 is equipped with several buzz-hunting features that help tackle noise at the source. Most audio buzz is caused by ground loops from AC power. The HE18's tools remove that AC hum and ground-loop potential, but leave the ground itself intact. The result? Audio that’s clean and crisp without any need to edit noise out in post. The HE18 also facilitates balanced and unbalanced line conversions. This tool ensures your gain stages match each other. Mismatched stages are a subtle but common cause of signal distortion.
Flexible lightweight design
Clocking in at just one pound with two output channels and multiple input options (1/4-inch TRS, RCA, 3.5mm), the HE18 is flexible and light enough for both field and home use. A totally passive design means there’s no need to carry a power source or manage additional cables. An impressive 20Hz to 70kHz response range is suitable for all audio genres whether you’re dealing with detailed low end, ample treble, or both.
