MFJ-126211262M Instruction Manual 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 micr opho ne co mpati ble for use
with any radio. Plug in an exter nal 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 jac k (like telephon es m i ght 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.
