The Kenwood MC-50 instruction manual provides detailed guidance on setting up the microphone, including impedance selection and connector alignment for both hand-held and base-mounted operations. It also covers the operation of the "Piano key" switches for transmit and receive functions, as well as troubleshooting tips for ensuring proper connectivity with transceivers.
Manual Overview
The Kenwood MC-50 is a dynamic cardioid microphone designed for amateur radio use, compatible with all Trio-Kenwood equipment. It features a die-cast zinc base for stability and “Piano key” switches for seamless transmit-receive switching. The microphone offers dual impedance settings: high impedance at 50k ohms and low impedance at 600 ohms, selectable via connector alignment. Sensitivity is rated at -56dB for high impedance and -76dB for low impedance, with a frequency response from 150Hz to 10kHz. For troubleshooting, ensure proper alignment of connectors and verify that the coil cord connections are secure. The microphone’s push-to-talk (P.T.T.) function can be operated via a slide switch for handheld use or the base unit’s key switches for mounted operation. No specific error codes or diagnostics are provided in the manual. Calibration involves selecting the correct impedance setting and ensuring the microphone is positioned at a minimum distance of 10 cm for optimal performance. Board-level guidance is not detailed in the manual.
Quick Issues Covered
- Diagnose push-to-talk circuit issues with 'Piano key' switches.
- Calibrate impedance using connectors A and B for Hi-Z/Lo-Z settings.
- Trace schematic for relay connections and audio output circuit.
Overview
The MC-50 is a cardioid dynamic microphone designed for amateur radio operation, compatible with all Trio-Kenwood Amateur Equipment. It features “Piano key” switches for smooth transmit and receive switching, and a die-cast zinc base for stability. The microphone has dual impedance ratings and selectable connectors for different operation modes.
Specifications
- Configuration Dynamic microphone with push-to-talk circuit.
- Element Moving coil type, unidirectional
- Impedance Dual ratings: Hi-Z 50k ohm + 30% (at 1000Hz), Lo-Z 600 ohm + 30% (at 1000Hz), Selectable: Connector “A”, Connector B’ switching
- Sensitivity —56dB + 3dB/50 k ohm, —76dB + 3dB/600 ohm (OdB=1V/zbar, T1000Hz)
- Frequency response 150Hz to 10KHz (—6dB)
- Recommended Operation Distance to mic.: 10CM (4") Minimum Distance
Controls & Indicators
The front-panel controls of the MC-50 include “Piano key” switches for send-receive switching, with one key for push-to-talk and another for the Lock Key function.
Installation / Setup
The installation of the MC-50 microphone involves selecting the appropriate impedance by aligning the microphone’s male connector A with either the RED H (Hi-Z) or BLACK L (Lo-Z) marker. For hand-held operation, the Coil Cord connector B’ should be aligned with the appropriate marker and the Slide Switch used for push-to-talk operation. For base-mounted operation, connector A’ should be aligned with the appropriate marker, and the Key Switches used as the Microphone Slide P.T.T. Switch becomes inoperative. The Coil Cord 5 pin female connector B’ must be joined to the Base 5 pin male connector B with the RED markers aligned. Finally, connect the Coil Cord 4 pin female connector to the transceiver.
Operation
The “Piano key” switches provide flexibility in send-receive switching. There are two keys; one for push-to-talk, and the other for Lock Key function. To lock the transmitter ON, press the Lock key. Pressing again returns the system to receive.
