In-Ear Monitor Amplifier is the core of a high-quality personal two-channel monitoring system for musicians. This lightweight unit is designed for performers who remain in a relatively fixed position on stage. It provides professional sound quality and a high-volume, high-fidelity signal allowing users to clearly hear a stereo or two separate monitor signals on any stage or in any studio. It can be used with a belt clip or mounted on a microphone stand using the integrated screw-on adapter. Simply activate the unit with the ON/OFF switch and adjust the desired volume for the headphone signal.
