## Long description

The Omnitronic MLM-81 8-channel 19" rackmount microphone preamp offers eight independent mic inputs with individual gain control, designed to raise microphone signals to line level for use in live sound, studio patch bays and broadcast setups. Its rackmount format conserves space and provides organized connectivity for multi-microphone configurations and recording chains. The unit focuses on reliable signal amplification and straightforward integration into existing audio systems.
Advantages
The preamplifier delivers consistent gain staging across eight channels, allowing matching of microphone levels before routing to mixers or recorders. Its 19" rackmount housing provides durable, space-efficient installation in racks and flight cases. Individual front-panel controls enable quick adjustments during setup or performance, while standardized audio connectors ensure compatibility with common professional equipment. The design emphasizes clear signal transfer and practical operation without unnecessary complexity.
Suitable for
Live sound reinforcement and multi-microphone stage setups
Studio patch bays and multitrack recording chains
Broadcast and streaming environments requiring multiple mic inputs
Installations where rack-mounted, space-saving equipment is required
Key specifications
Channel count: 8 independent microphone preamplifier channels
Form factor: 19" rackmount unit suitable for standard equipment racks
Gain control: Individual gain knobs per channel for level adjustment
Inputs: Microphone-level inputs for dynamic and condenser microphones (requires external phantom power sources when applicable)
Outputs: Line-level outputs for connection to mixers, recorders or patch bays
Construction: Metal rack chassis designed for professional use and mounting
How to use
Install the unit in a standard 19" equipment rack and secure it with appropriate mounting screws. Connect microphones to the channel inputs and route the line-level outputs to mixer channels, audio interfaces or recording devices. Use the individual gain controls to set each microphone’s level, monitoring signal strength and headroom on your downstream equipment. If using condenser microphones that require phantom power, supply phantom power from the microphone input device or an external phantom power source, as the preamp requires an appropriate phantom power arrangement when applicable.
Usage recommendations
Use conservative gain settings during initial setup, then fine-tune while monitoring to avoid clipping. For consistent results across multiple channels, match gain values while listening to a reference source or using meters on your mixer or recorder. Ensure proper rack ventilation and secure mounting to reduce mechanical noise and maintain long-term reliability.
