Donner EM1 Rechargeable Portable Personal In-Ear Monitor Amplifier

Designed specifically for stage musicians, the EM1 is a rechargeable and portable personal in-ear monitor amplifier that boasts outstanding technical and sonic characteristics. Translating high-quality audio reproduction into a more compact format, the EM1 allows you to clearly hear the sound of your performance on stage anytime, anywhere, whether you're a drummer, keyboardist, vocalist, or other musician.

Featuring a professional-grade XLR and TRS input connector with a locking mechanism, the EM1 offers a stereo/mono source switch depending on the cable connection. When the XLR is connected to a balanced input, the EM1 will output in balanced mono, while the TRS connection to an unbalanced input will result in an unbalanced stereo output.

Powered by a long-lasting Li-ion battery that provides up to 12 hours of use, the EM1 can be recharged via the Micro USB Type-C jack, which accepts a DC 5V, 1A or higher current. The LED indicator will glow red to signal that the device is charging.

The EM1 is equipped with a 1/8" TRS headphone output, designed to work optimally with impedance-matched headphones ranging from 8Ω to 250Ω, ensuring a superior listening experience.

Boasting an analog circuit design, the EM1 delivers impressive technical specifications. The 1/4" TRS impedance is 10K, the XLR impedance is 20K, and the headphone output impedance is a low 10Ω. The maximum input level is +2dBu, and the maximum output power is 125mW @ 32Ω. The device's noise level is a respectable -77dB (A-weighted), with a remarkably low THD+N of 0.001% and a dynamic range of 96dB.

Drawing a current of 70mA, the EM1's rechargeable 1000mAh Li-ion battery can be fully charged in approximately 4 hours, providing over 12 hours of continuous use. Compact and portable, the EM1 measures 103.4mm (D) x 41mm (W) x 40.7mm (H) and weighs just 95g.

Included with the EM1 are a Micro USB charging cable, a 1/4" TRS to 1/8" TRS stereo audio cable (male to male), and a user manual, making it a complete and versatile solution for stage musicians.

Key features of the EM1 include: - High-power headphone amplifier suitable for use with high-impedance professional headphones, ensuring adequate volume even in noisy environments (note: does not support microphones) - Outstanding technical and sonic characteristics, delivering exceptional audio reproduction for professional in-ear monitoring - Practical interface with XLR and TRS input connectors, along with a stereo/mono source switch - Strong battery endurance, with up to 12 hours of runtime on a single charge - Compact, portable, and easy to carry design with a solid metallic belt-clip
