K-PO MB+5 DX Power microphone 4 pins

The K-PO MB+5 P4 is a robust desk microphone designed for CB and amateur radio use. It features rotary controls for precise adjustment of volume and tone, allowing you to set the audio to your personal preference.

The microphone connector is pre-wired for use with our K-PO DX-5000 series, CRT SS-6900 series, AnyTone AT-5555 series and other equivalent radios.

A built in high gain amplifier of approximately 35 dB delivers a strong and clear audio signal, while the integrated volume compressor ensures consistent modulation during transmission. The output level can be accurately matched to almost any transmitter, and the internal equalizer allows fine tuning of the sound characteristics.

The microphone operates on a 9 Volt battery, which is not included. An integrated analogue VU meter provides continuous visual feedback of the modulation level, helping you maintain optimal audio performance at all times.

Always check carefully if your transceiver is compatible with your version of the MB+5 microphone. We are not responsible for any damage caused due wrong usage (or wiring) of the microphone to your microphone or transceiver.
