Overview
The EZ-MCP1 is an in-line microphone compressor that produces consistent audio levels despite wide variations (up to 30 dB) from the microphone. It is installed between a dynamic or condenser microphone and a mic-level mixer or amplifier input. The only setup required is a front-panel level trimmer that is adjusted during normal speech until the compression LED just begins to flash. A rear-panel output level trimmer is provided although it is typically left in the normal default position. Phantom voltage (24 V) is automatically switched on when the EZ-MCP1 output is connected to a mic jack that provides phantom voltage. The EZ-MCP1 improves sound quality and intelligibility by producing consistent audio levels and controlling overloads that produce distortion and clipping. It is used for recording, paging and public address in houses of worship, restaurants, clubs, meeting rooms, educational facilities, conference rooms and commercial sound systems.
