XLR microphone cables are among the most common type of cables in the audio industry. XLRs connect condenser and dynamic microphones to sound mixers and amplifiers. TA4F cables are referred to as "Mini XLR" cables. They feature four pin holes compared to three in XLR cables. XLR audio signals can be converted to TA4F with the help of an adapter.
Things You'll Need
XLR cable
TA4F cable
XLR to TA4F adapter
Determine the gender of the XLR to TA4F adapter. Most adapters contain female inputs on both ends. Female adapter ends will have small holes in them. If your adapter contains holes on both ends then you must use male XLR and TA4F cables.

Insert the male end of the XLR cable into the female XLR input on the adapter.

The male XLR cable end will have three prongs that match that XLR input holes on the adapter. Slide these prongs into their matching holes. You will hear a "click" noise when the XLR cable connects securely to the adapter.

Insert the male side of the TA4F cable into the female TA4F input on the adapter. The TA4F will have four prongs instead of three. Slide these prongs into place into the TA4F input just as you did for the XLR side.

Connect the XLR and TA4F cables to an audio system. The other side of the XLR and TA4F cables must be connected to an audio source like a microphone or to an audio processor like a sound mixer. Review your microphone's or mixer's user guide for further instructions on connecting audio cables.

Send audio signal through the cables and test the connection. The cables must be connected to audio speakers before you can test the sound. Review your speaker's user manual for further instructions on connecting audio cables. Speak into the microphone connected to the audio cables. Listen for audio from the speakers as you speak. Repeat steps one through five if you do not hear audio.
