JH Audio™ is proud to introduce the Pearl™ Tri Amp Micro Speaker Management System, our latest innovation in audio technology. The system includes our PC-based Pearl™ Control Software and Pearl™ Loader program, which offer functions that allow users to precisely control gain, phase, time, and equalization of low, mid, and high frequencies of an in-ear monitor.

The Pearl™ system is sold with a pair of JH Audio’s™ Ruby Universal™ in-ear monitors, pictured here with our signature Ruby Universal™ design (not customizable). When used together, the Pearl™ and Ruby™ will make it possible to reproduce any frequency response or audio signature.

This Pearl bundle is also available with a custom-fit Ruby IEM.

Included with the system is our Pearl™ Control Software that allows the user to shape the audio and program the Pearl™ with user-defined, instantaneous presets. Multiple frequency response preset files will be included in the software; we will publish new preset files as they’re developed. Using this software, users can set different levels for each ear, which is especially beneficial to those experiencing hearing loss. Additionally, the Pearl™ Loader function is used to instantly change the Pearl™ Processor from one frequency response setting to another via a USB-C cable.
