Check the listing for details. RDL EZ-MCP1 Microphone Compressor. Condition: New. Listed at 225.13 USD. Radio Design Labs' 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.Radio Design Labs EZ-MCP1 Features:Produces Consistent Levels from Any MicrophoneInstalls Between Microphone and Mixer/AmplifierImproves Intelligibility with Fast Automatic Level ControlControls Overloads that Cause Distortion and ClippingFront-Panel Set-Up Trimmer with LED IndicatorAutomatic Phantom Voltage Switching with LEDXLR Input and OutputGold-Plated Connector ContactsSimple Setup using LED IndicatorExceptional Level Control Range (30 dB)Radio Design Labs EZ-MCP1 Specifications:Input: Mic level, -60 to -30 dBu nominalInput Impedance: >1k Ohms balancedInput / Output Connectors: XLRLevel Adjustment: Single turn audio taper (front panel)Minimum Input Level:60 dBu (to cross compressor threshold)@ max gain30 dBu (to cross compressor threshold) @ min gainMaximum Input Level: 0 dBu @ min gainOutput: Mic level, -55 dBu to -30 dBu, adjustable; NORMAL: -45 dBuOutput Impedance: 150 Ohm nominal, balancedOutput Level Adjustment: Single turn audio taper (rear panel)Frequency Response: 50 Hz - 20 kHz (+/- 0.5 dB)THD+N:Compression: 30 dB, automatic adjusting attack and release timesNoise:CMRR: >55 dB (50 Hz to 120 Hz)Phantom: 24 V (IEC 1938: 1996-12), present when phantom detected at module outputIndicators:Red LED: Compression - Indicates compressor activityGreen LED: Phantom - Indicates phantom voltage presentBlue LED: Power24V DC power supply current: 55 mA (idle), 60 mA (max.), 70 mA (max. with phantom)Power Supply Input Voltage: 100 to 240V ACWarranty: 3 Years; contact RDL technical support department for assistanceCase Dimensions: 2.9" W x 5" DMounting Size: 1/6 rack width
