I recently purchased a Ten-Tec Speech processor model 234 to utilize with my Drake TR7A, both are (4) pin connectors, however the pin-out is different. I wanted to stay with the Drake line, specifically SP75 speech processor but I could not justify spending 2+ times the cost.
The output cable of the 234 plugs into transceiver (I assume needs to be rewired) and the Shure microphone plugs into the 234 (I assume needs to be rewired)
Now to my request......could anyone be specific as to the wiring from the microphone that I use (Shure model 450) to the Ten-Tec Speech processor model 234.http://cdn.shure.com/user_guide/upload/405/us_pro_450seriesii_ug.pdfhttp://www.qsl.net/tentec/manuals/234.pdf
Thank you in advance.
