Intended to produce consistent audio levels despite wide variations in the microphone output due to inconsistent technique, the EZ-MCP1 is installed between a dynamic or condenser microphone and a microphone-level input to a mixer or amplifier. This improves sound quality and intelligibility by producing consistent audio levels and controlling overloads that produce distortion and clipping in applications including, paging and public address in houses of worship, restaurants, clubs, meeting rooms, educational facilities, conference rooms and commercial sound systems.
The EZ-Series offers a wide range of stand-alone designs including distribution amplifiers for line level audio, headphones, composite and XGA/XGA video, audio pre-power and mixer amplifiers, AV input selectors and computer video selectors. All models may be connected and operated without the use of tools, using standard cables. They are housed in enclosures with the same height, with widths in increments of one sixth of a rack-width, so they may be mounted singly or in multiples in a range of accessory mounts. Audio and video are switched using solid-state circuitry to avoid degradation due to dirty switches; critical connectors are gold-plated for reliable connections. All use 24 volt power, supplied from external AC adapters.
On the front panel there is a 3-pin XLR connector for the microphone input, and a blue LED to indicate power is present. Another green LED indicates when 24V phantom power is switched on; this happens automatically when the EZ-MCP1 output is connected to a microphone input that provides phantom voltage. A preset rotary control is adjusted during normal speech until the red compression LED just begins to flash. The rear panel has an 3-pin male XLR for the balanced microphone output and a preset rotary control to set output level. Power is connected with a locking co-axial connector
