EMB Professional EBM55 Dual UHF Wireless Microphone System

The EMB Professional EBM55 is a dual UHF wireless handheld microphone system designed for two-person voice and vocal applications. It combines two battery-powered handheld transmitters with a portable rechargeable receiver for a compact wireless setup. This configuration helps eliminate microphone cables between presenters or performers and the audio system.

The EBM55 is suited to karaoke, DJ use, weddings, classrooms, churches, business presentations, stage events, and outdoor gatherings. Its dual-handheld format supports duets, shared announcements, interviews, and presentations with two active users. The published operating range is up to 60 meters when the receiver has a practical wireless path to the microphones.

For vocal reproduction, the microphones are specified with a 60 Hz to 18 kHz frequency response, a 100 dB dynamic range, and a 98 dB signal-to-noise ratio. These published specifications position the system for spoken word and general vocal use. UHF operation and selectable channels provide flexibility when configuring the system in its intended operating environment.

The system provides 45 selectable UHF channels with 250 kHz channel spacing. EMB specifies auto mute and an impact-eliminating circuit to help limit unwanted noise during power-on and power-off operation. The receiver uses DPLL receiving mode and is rated with a published sensitivity of 7 dBµV.

Connect the receiver to compatible speakers, amplifiers, mixers, or DJ controllers through its optional 1/4-inch jack connection. This makes the EBM55 an appropriate add-on for portable PA, karaoke, and event sound systems that accept a suitable audio input. Select the proper cable or adapter for the destination equipment before installation.

Design & Installation

The EBM55 combines two handheld wireless transmitters with a compact portable receiver. EMB identifies built-in transmitter antennas and a BNC receiver antenna input with 50-ohm impedance. Detailed enclosure-material and construction specifications are not published for this model.

Place the receiver near the mixer, powered speaker, amplifier, or DJ controller, then connect it with the appropriate optional 1/4-inch cable or adapter. Power the handheld microphones, select the desired UHF channel, and adjust microphone level at the receiving audio equipment. For practical wireless performance, position the receiver where it has a clear path to the handheld microphones.
