EMB Professional EMC900R Large-Diaphragm Condenser Microphone

The EMB Professional EMC900R is a wired large-diaphragm condenser microphone for project-studio recording and other XLR-based audio applications. Its red zinc-alloy body and standard 3-pin XLR connection make it suited to recording setups that use a compatible mixer, microphone preamp, or audio interface. It requires 48V phantom power, so it is intended for equipment with a suitable phantom-powered microphone input.

This microphone is listed with a cardioid, unidirectional pickup pattern that concentrates capture toward the front of the capsule. That focused pattern can help reduce sound entering from behind the microphone when compared with an omnidirectional design. It is appropriate for placing in front of a vocalist, instrument, presenter, or other intended sound source.

The EMC900R has a published frequency response of 30 Hz to 20 kHz, supporting broad-range capture for voices and instruments. Its listed sensitivity is -38 dB, with a 76 dB signal-to-noise ratio and 18 dB A equivalent noise level. These specifications describe a condenser microphone designed for detailed close-mic recording with compatible gain staging.

A large-diaphragm capsule is central to the EMC900R design, while onboard sensitivity adjustment and high- and low-frequency adjustment are listed for adapting the microphone to a source or setup. The microphone also includes a power-indicator light to show operating status when connected to phantom power. Its published 135 dB maximum input SPL supports use with louder sources when placement and input gain are managed appropriately.

The EMC900R fits into a conventional balanced XLR signal path between a sound source and a phantom-powered audio interface, mixer, or microphone preamp. It can be used for project-studio recording, broadcasting, television-oriented audio work, and supported stage applications. A stable microphone stand, suitable XLR cable, and properly configured 48V phantom power are needed to integrate it into a recording system.

Key Features

• Large-Diaphragm Capsule: Supports detailed condenser-microphone capture for recording applications.
• Cardioid Pickup Pattern: Focuses pickup toward the front of the microphone.
• 48V Phantom Power: Works with compatible powered XLR microphone inputs.
• 30 Hz–20 kHz Response: Covers a broad published audio frequency range.
• Onboard Adjustments: Includes listed sensitivity and high/low-frequency adjustment controls.
• Zinc-Alloy Housing: Provides a metal body with a red exterior finish.

Design & Installation

The EMC900R uses a red zinc-alloy body and a large-diaphragm condenser configuration. Its physical design includes a 3-pin XLR connector, power-indicator light, and listed adjustment functions for sensitivity plus high- and low-frequency response. The handheld or stand-held form factor allows it to be positioned for fixed recording or supported live-use applications.

Connect the microphone with an XLR cable to a microphone preamp, mixer, or audio interface that provides 48V phantom power. Mount it securely on a compatible microphone stand and aim the front cardioid pickup side toward the performer or sound source. Start with moderate preamp gain, then adjust microphone placement and the listed onboard controls as needed for the source and room.
