switch, etc) to any of four radios at the push of a button. You can switch between a headset, desk or hand mic, TNC, Phone Patch, Sound Card, etc. The Multi-Switcher matches the impedance, audio level and pin-out of nearly any microphone to virtually any radio including vintage rigs. The Multi-Switcher also switches your foot- or hand-switch and CW keyer to the selected radio.
Works with nearly ANY Microphone or Other Audio Source.
Pushbuttons select one of four audio sources. Matches most any microphone or other audio source to most radios. Preset controls avoid adjustments when switching microphones. Now you can switch between a headset, desk or hand mic, phone patch, sound card, voice keyer, tape recorder etc without plugging and unplugging cables. Two adjustable high gain stages make low output mics and low sensitivity radios WORK and SOUND MUCH BETTER!
