The Samson EarAmp EWM100 Wireless In-Ear Monitor System, 470-502 MHz is a wireless stereo in-ear monitor system that offers performers the flexibility to move and showcase their talents on stage while maintaining high audio quality. Its user-friendly setup and customizable mixes enable musicians, theatrical artists, presenters, and broadcasters to hear their performances clearly and accurately.

Integrating wireless in-ear monitoring into your setup is straightforward with the Samson EarAmp. This system wirelessly transmits audio signals to in-ear monitors worn by performers, eliminating the need for bulky floor monitors, which can be inconvenient to transport and manage during live performances. With EarAmp, performers can hear themselves and their fellow musicians clearly and instantaneously, granting them more control and enhancing their performances.

The compact stereo bodypack ER100 receiver allows for easy customization of your monitoring experience. It comes with a 1/8” headphone level output and a large volume control for quick adjustments. The receiver also features controls for activating a high EQ shelf, limiter, balance, and stereo/mono operation, enabling you to fine-tune your sound preferences. Its high-contrast display ensures that all settings are easily visible, even in low-light conditions. The ER100 is powered by two AA batteries, providing up to 6 hours of usage.

Designed for durability in touring and stage environments, the half rack unit ET100 Transmitter includes two XLR-1/4” combo inputs for connecting various audio sources. Additionally, two 1/4” output jacks allow for the mix to be sent to multiple locations. A 1/4” headphone jack provides engineers with easy access to monitor the transmitted signal. The high-contrast display ensures clear visibility in low-light settings, while the large encoder and buttons grant access to all settings. The ET100 features a detachable antenna that can be mounted to the front or rear BNC connectors or set up remotely. The ET100 can broadcast to multiple ER100 receivers for simple system expansion.

Setting up the EarAmp system in any venue is a breeze. Perform a quick scan to identify the clearest operating frequency from either the transmitter or receiver. Selected frequencies can be added to a custom preset group, allowing engineers to cycle through and monitor all mixes from a single receiver. Both the receiver and transmitter can be named, simplifying the management of multiple systems. The EarAmp system includes a rackmount kit that enables two systems to be mounted side by side.

The included Zi150 earphones deliver exceptional sound quality with impressive dynamics. They come with three foam and three rubber ear tips to ensure a comfortable and secure fit for all ear types. The foam tips provide long-lasting comfort and conform to the ear's shape to stay in place during performances. Additionally, the earphones effectively block outside noise, allowing performers to focus on the music. Lastly, they offer robust bass response to enhance the overall listening experience.
