Emb Uhf EMIC2300HT Professional Quad / 4 x Wireless Headset Microphone System

The EMB Professional EMIC2300HT is a four-channel UHF wireless headset microphone system built for situations where multiple presenters, instructors, performers, or speakers need to be heard at the same time. It combines one quad-channel receiver with four bodypack transmitters and four condenser headset microphones. This configuration helps simplify multi-user voice reinforcement without requiring four separate wireless systems.

Designed for spoken-word applications, the EMIC2300HT provides a specified 40 Hz to 15 kHz frequency response and more than 90 dB of dynamic range. FM modulation supports clear voice transmission for presentations, group fitness, worship, classrooms, karaoke, and small event setups. Its specified operating range is up to 50 m in ideal conditions.

The system uses PLL frequency selection across a stated 480–680 MHz UHF range, while the receiver uses DPLL reception. This architecture is intended to support stable wireless operation across its selectable frequency range. Frequency stability is specified at ±30 ppm.

Each included bodypack transmitter has a built-in antenna and DSP modulation, with stated RF output from 10 to 30 mW. The bodypacks operate on two AA 1.5 V batteries each and are specified for approximately 6 to 8 hours of use. Four condenser headset microphones are included for hands-free operation.

For system integration, the receiver provides mixed and balanced audio output paths. This makes the EMIC2300HT suitable for connection to compatible PA, mixer, amplifier, or recording systems using the appropriate audio cabling. It is a practical choice when a four-person headset solution is needed in one coordinated receiver package.

Key Features

• Four-Channel Operation: Supports four bodypack-and-headset users simultaneously.
• Included Headset Microphones: Includes four condenser headset microphones for hands-free speaking.
• UHF PLL Selection: Uses selectable frequencies across the stated 480–680 MHz range.
• DPLL Receiver Design: Provides DPLL reception for the quad-channel receiver.
• Mixed And Balanced Outputs: Offers two audio-output formats for compatible sound systems.
• AA Battery Bodypacks: Each transmitter uses two AA batteries for portable operation.

Design & Installation

The EMIC2300HT is organized around a single quad-channel receiver and four matching bodypack transmitters, keeping a four-user wireless setup consolidated in one system. The bodypacks use built-in antennas, and the included condenser headset microphones provide a hands-free microphone format. Published specifications identify the operating design and included components, but do not specify chassis or headset materials.

Position the receiver where it has the clearest practical path to the bodypack transmitters, then connect its mixed or balanced output to a compatible external audio system. Fit each headset securely, connect it to its assigned bodypack, and install two AA 1.5 V batteries per transmitter. Actual range can vary with obstructions, RF conditions, battery condition, and installation environment.
