Microphone Control Center

INTRODUCTION

Thank you for purchasing the new MFJ-1262. Your new microphone control center allows you to switch between two microphones with the push of a button. From a boom mic/headphone to a desk or hand mic, a hi-fi ragchewing mic to a hard-hitting DX mic, or a hand mic to a desk mic, switching microphones is now quick and easy. Moveable jumpers allow you to make any 8-pin microphone compatible for use with any radio. Plug in an external PTT foot switch to free your hands for contesting and DXing. Alternatively, let a computer or voice keyer control the PTT line for automated operation. Plug in headphones and set the volume to privately monitor

transmissions. Or, push in the speaker ON/OFF switch to broadcast your transmissions over your radio's speakers.

MICROPHONE AND RADIO CONNECTIONS

Different manufacturers and different radios may wire the same style connectors differently. The MFJ1262 and 1262M have internal headers that use small moveable jumpers. The MFJ-1262 uses common round 8-pin microphone connectors found on most transceivers. The MFJ-1262M comes with an 8-pin modular microphone jack (like telephones might use).

Internal jumpers are used to program connections for any radio that connects to the prewired connectors. This feature eliminates the need for soldering jacks or purchasing adapter cables. The MFJ-

1262/1262M must be configured using the internal jumpers before use.

The microphone/radio setup procedure requires a few minutes of time. Before you start, you will need the manual of your radio and microphone readily available.

IMPORTANT INFORMATION CONCERNING THE MFJ-1262M

Note: The MFJ-1262 and MFJ-1262M jumpers only allow for the programming of one microphone pin-out to one radio pin-in. To use another microphone, it must have the

same 8-pin output configuration as the microphone currently programmed for use.
